Moreover, the Report of the Board of Directors includes the explanatory report under paragraph 7, article 4, Law 3556/2007

Fiscal year 2021 was characterized by the final settlement of chronic outstanding issues with the Greek State:
- The renewal of the exclusive right of water supply and sewerage in the area of responsibility until 2040
- The determination of the reasonable transaction price in relation to the raw water supplied by EYDAP Fixed Assets Company to
EYDAP during the period 12/10/2013-31/12/2020, i.e. 157.2 million euros
- The determination of the sale price of raw water by the Greek State to EYDAP for the next 20 years - lower by about 40%
compared to the price paid by EYDAP from 2004 to 2013 and
- The agreement for the signing of the contract for the operation and maintenance services of the External Water Supply System
(EWSS) for three (3) years.
As a capstone, on December 24, 2021, the Extraordinary General Meeting of the Company's Shareholders decided to ratify the
agreement between EYDAP and the Greek State. The contract with the Greek State, which follows the recent issuance of the
relevant law 4812/2021, includes the renewal of the exclusive right and the definition of the exchange of water supplied by
EYDAP SA. The overdue debts of EYDAP to the Greek State for the supply price of raw water for the period 2013 - 2020 as well as
the operating costs of EYDAP SA for the management, maintenance and supervision of good operation of EWSS during the same
period, were determined by no. 352462 / 14.12.2021 J.M.D. (Government Gazette 5830).

regulatory framework provided by J.M.D 135275 (no. 3, par. 9) Government Gazette 1751/22.05.2017, which we expect to be

Environment and Energy, or through a new Independent Water Regulatory Authority.
The goals of the Company are its transformation into a more efficient organization, the efficient utilization of water resources,
the sustainability of its investments, the strengthening of its market value, the achievement of a reasonable return on invested
capital, the attraction of new investors, the securing of a fair and dynamic work environment, the creation of new jobs, as well as
the provision of added value to society through the improvement of the level of services we offer and the development of new
water supply & sewerage networks.

Ι. Presentation of the Company’s Key Financial Results
In 2021, post due debts of EYDAP S.A. and the Greek State determination was finalized following the publication of no. 352462 /
8.12.2021 Joint Ministerial Decision (JMD) (Government Gazette B '5830 / 14.12.2021) which defined the post due debts: (a) of
EYDAP to the Greek State due to supply of raw water in accordance with the provisions of par. 2 of Article 2 of Law 2744/1999
and the Contract 1999 and (b) of the Greek State to EYDAP for the period from 12.10.2013 to 31.12.2020. The amount due by
EYDAP SA for the amount of raw water supplied in the period from 01.10.2013 to 31.12.2020, stood at Euro 346.7 million while
the receivables for management, maintenance and supervision services of its proper External Water Supply System operation
during the same period amounted to Euro 189.5 million. The aforementioned JMD stated offsetting the above receivables
between the Greek State and EYDAP SA and that the latter should pay the balance, after the offset, amounting to Euro 157.2
million. The above items were invoiced on 28.12.2021.
At the end of the year, a decision of the Extraordinary General Meeting of Shareholders of EYDAP held on 24.12.2021 approved
the terms of renewal the right under par. 1 of Article 114 of Law 4812/2021, the consideration paid by EYDAP for the supply of
raw water, the specific rights and obligations of EYDAP as well as any other regulated issue for the achievement of the objective
of the granted right and the other relations between the contracting parties. On 02.02.2022, the relevant contracts were signed
between the Greek State, EPEYDAP and the Company regarding the supply of raw water and assignment of provision of
operation and maintenance services of the external water supply system effective from 01.01.2021.
On 27.04.2022 a memorandum of understanding was signed which regulated the implementation of the contracts and
specifically clarified that the right to exclusive supply of raw water is provided in return for the entire twenty years (01.01.21 -
31.12.2040) of the Contract, which amounts to Euro 87.5 million amortized over twenty years of the contract. Moreover, it was
agreed that the selling price of raw water is determined on the basis of a price per cubic meter applicable for every reporting
year according to a table included in that contract and for the year 2021- the burden amounts to Euro 28.4 million. The
consideration paid for the intangible asset as well as for the annual supply of raw water is paid by E.YD.A.P. to EPEYDAP and is

further available from the State for financing operation, maintenance and upgrade of the External Water Supply System (EYS) of
the major Capital region.
Article 9 (Contractor's Fee) of the EYS contract makes provisions for the services of regular operation and regular maintenance, a
fixed annual flat fee of twenty-five million Euro 25 million is agreed upon, in addition to the corresponding VAT for the three-
year period of validity and in case of its extension, for an additional six months, the consideration will amount to Euro 12.5
million.
As a consequence of the above, in 2021, EYDAP SA recognized the exclusive right to water supply, in the statement of financial
position, in the item "intangible assets" amounting to Euro 87.5 million as well as in the Income Statement:
• "cost of sales" item (depreciation) amounting to Euro 4.4 million,
• "cost of sales" item (raw water burden) the annual cost of raw water supply amounting to Euro 28.4 million,
• "turnover" item, income from the Operation and Maintenance Contract amounting to Euro 25 million. This
receivable for cash collection purposes will be offset with the corresponding EPEYDAP receivable from
granting the exclusive right to water supply.
The Company’s turnover amounted to € 360.8 million against € 330.3 million in 2020, recording an increase of 9.2% (+ € 30.4
million). The amount of 25 million arising from this increase is due to the revenue from the Operation and Maintenance Contract
of the External Water Supply System (owned by EYDAP Fixed Assets) according to the respective contract that has been signed.
According to this contract, this amount is not paid in cash but is offset with the corresponding obligation to EYDAP Fixed Assets
for operation and maintenance of these facilities for 3 years (with the possibility of extension by six months) due to the granted
a discount from the initial prices for raw water. Excluding this revenue, turnover would have been increased by € 5.4 million (+
1.6%) to € 335.8 million. In total, the Company’s key operations (water supply and sewerage) presented an increase in revenues
of € 6.1 million (+ 1.9%).
In particular, revenues from water supply and related services increased by € 4.5 million (+ 2.0%), while revenues from sewerage

18% (+37 k €), other revenues mainly consisting of revenues from disconnections / reconnections / withdrawal of hydrometers
increased by +273 k € (+ 18%) and finally, the category of revenues from restoration works increased by +54 k (+ 19%). This
revenue category is linked to the water customers' hydrometer replacement plan included in the company's investment plan.
It should be noted that revenues from water consumption (as well as the revenues from the right to use sewerage related
services), in addition to the invoiced revenue shown in issued water bills, also include the adjustment to this revenue on an
accrued basis. For financial year 2021, these amounts stood at € 214,534 k and € -7,790 k respectively.

to income invoiced after termination of water supply (fixed charge, minimum consumption, water price in case of violation) and
which - due to the application of IFRS 15 and the respective revenue recognition criteria - are deducted from revenues and
therefore are recognized as revenues only upon the cash collection from the customer.

Adjustments from the application of IFRS 15, amounting to € +8 k (versus € +1,046 k in 2020). These adjustments are linked to
the revenues priced after the termination of water supply (fixed charge, minimum consumption, water price in case of violation)
and which, due to the application of the revenue recognition criteria in the context of IFRS 15, are deducted from revenues and
therefore are recognized as revenues only upon the cash collection from the customer.

ALTERNATIVE PERFORMANCE MEASURES (“APMs”)
In the Annual Management Report, as well as in its disclosures to the investors, the Group utilizes Alternative Performance
Measures (APMs) in addition to the financial sizes included in its financial statements which are prepared in accordance with the
current financial reporting framework.
The objective of the analysis of the APMs is that both - the Company's Management and the investors – should have a more
complete picture of the Group's profitability, capital structure, operations and liquidity and in no case should they be taken into
account independently of the measurement indicators. arising directly from the financial statements.
The Group uses the following Alternative Performance Measures:
EBITDA
This Ratio is prevailing in the investment community and is part of the general category of profitability ratios, having the
advantage of isolating the effects of financial-investment results, income tax and the main category of non-cash expenses which
are depreciation and amortization.
The Ratio is calculated by deducting the cost of sales, distribution expenses, administrative expenses, other expenses and adding
other operating income and total depreciation/amortization. Moreover, the item "Impairment of financial assets" of the Income
Statement is deducted, which relates to the provision-expense of doubtful receivables for the period, which in previous periods
was included in the cost of sales. These sizes are used without any adjustment in the Financial Statements and Notes.

• Return on Equity/ROE
In general, return on equity presents the profit that corresponds to the investment of the company’s shareholders. It belongs to
the group of profitability ratios and is also generally used for the purpose of comparing similar companies and evaluating the
company’s management. The ratio is calculated by dividing net income (Profit after Tax) by the average of opening and closing
period equity. It can also be calculated by multiplying five factors, each one of them is corresponding to a separate ratio.
Separate ratios are as follows:
Tax Burden: which is the ratio of Net Income (Profit after Tax) to Profit before Tax
Interest Burden: which is the ratio of Earnings before Tax to EBIT
EBIT margin: is the ratio of EBIT to Turnover
Assets Turnover: which is the ratio of Turnover to Total Assets (average Total Assets at the opening and closing period).
Leverage: which is the ratio of Total Assets (average Assets Total at the opening and closing period) to Equity (average Equity at
the opening and closing period).

By means of analyzing the Return on Equity Ratio into five separate factors, the Company’s Management, as well as the
stakeholders, can be aware of what part of the net profit is burdened with tax (Tax Burden), what part is burdened or benefits
from the financial or investing activity (Interest Burden), what is the contribution of operating profit margin (at EBIT level - the
EBIT margin), what is the Asset Turnover and finally what is the contribution of Leverage.
• Operating Expenses (OPEX)
The Ratio is used by the Company’s Management in decision making and in its communication with investors as it includes all the
categories of expenses that are divided into operations, i.e. cost of sales, administrative expenses and distribution expenses net
of depreciation. It also includes the item "Impairment of financial assets" in the Income Statement, which concerns the
provision-expense of doubtful receivables for the period, which in previous periods was included in the cost of sales. Other
expenses are excluded as they cannot be allocated to operations.

Alternative Performance Measures less the effect of provision for the additional cost of raw water
• Adjusted EBITDA
In 2020, the Company made a provision for the additional cost of raw water for the period 2013-2020, amounting to € 157.5
million, which burdens the income statement of the current year.
In 2020 the provision amounts to approximately € 22.2 million, and is included in the cost of sales. For the years 2013 to 2019,
provisions made amounted to € 135.3 million in total, and are included in the Other Expenses item.
In 2021 the Company was burdened, based on the consideration provided in the contract signed with the Greek State, by €
28,395 k. Moreover, based on the Operation and Maintenance contract of EYS, it formed an Intangible Asset of € 87,500 k (due
to granting a lower price for the real estate than the initial price). In 2021, the Company depreciated one twentieth of this
amount, which corresponds to € 4,375 k. Having undertaken an equal obligation of 87,500, it entered the corresponding
obligation for the provision of operation and maintenance services at the beginning of the fiscal year and decreased it by €
25,000 k, recognizing an equal amount of income.
To facilitate the separation of the adjustments in relation to raw water first recorded in the Financial Statements of 2020 and
finalized in 2021 through both - the concession contract and the operation and maintenance contract of the EYS - and to capture
in the best possible way the performance of the company regardless of these events, we adjusted EBITDA, deducting the
relevant effects. In particular, the Ratio is calculated if the cost of sale, distribution expenses, administrative expenses and
miscellaneous expenses are deducted from the turnover and the other operating income and total depreciation are added.
The item "Impairment of financial assets" in the Income Statement is also deducted, which concerns the provision-expense of
doubtful receivables for the period. Provision for the cost of raw water for 2020 (which is included in the cost of sales) and
provision for the costs of raw water for the period 2013-2019, included in the Other Expenses item, are added to the relative
total. In 2021, both the cost of the raw water under the contract as well as the income of the operation and maintenance
contract and the cost of the amortization of the intangible asset are deducted.

To facilitate the separation of the :
• adjustments recorded in the Financial Statements of 2020 and 2021 for the first time in relation to the raw water as
well as
• significant change in the impairment of financial assets
and in order to present in the best possible way the company’s performance regardless of these extraordinary events, we
adjusted EBITDA, deducting the relevant effects.
In particular, the Ratio is calculated by deducting the cost of sales, distribution expenses, administrative expenses, other
expenses from turnover and the other operating income and by adding the total depreciation/amortization. The item
"Impairment of financial assets" in the Income Statement is also deducted, which concerns the provision-expense of doubtful
receivables for the period. Provision for the cost of raw water for 2020 (which is included in the cost of sales) and provision for
the costs of raw water for the period 2013-2019, included in the Other Expenses item, are added to the relative total.
Impairment of financial assets is not included either.

Respectively, the invoiced consumption decreased by -4.5%, resulting in a decrease in non-invoiced consumption. The non-
invoiced water is the reason for the annual non- invoiced consumption in the internal water supply system (I.W.S.S.) of EYDAP,
to the annual volume of water output of water treatment plants. The non-invoiced consumption is calculated on the basis of the
consumption data from which the water supply revenues of refined water within I.W.S.S. are derived in the financial statements
of the company. In 2021 the non-invoiced water amounted to 25.4%, increased by 2.2% compared to 2020.

The decrease in invoiced consumption by 4.5%, which corresponds to 14 million cubic meters, is mainly due to the General
Tariff, which recorded a decrease of -9.3%, corresponding to -18.7 million cubic meters . The decrease of the general invoice is
attributed to the suspension of invoicing from 27.04.2021 to 15.06.2021 and from 07.09.2021 to 08.11.2021 due to the lack of a
postal service provider, which resulted in the delay of revenue invoicing mainly in the general invoice category. The Company
temporarily restarted the daily issue of accounts from 16.06.2021 and definitively on November 8. On November 15, the
distribution of the accounts to the consumers started.
A lesser effect on the amount of invoiced consumption was caused by the increase in the consumption of raw water from
external aqueducts, by 19.5%, which corresponds to 1.5 million cubic meters. The increase in the consumption of external
aqueducts is mainly due to the size of the needs of the Municipality of Oropos, defined by the degree of operation of the
pumps, in drillings belonging to the Municipality itself, in the area of Mavrosouvala.
During the year 2021, the gradual lifting of the restrictions imposed due to the pandemic, does not seem to have had a
significant impact - it seems to have had a slightly increasing effect on the separate categories of Industrial – Business and
Network upgrade tariffs.
In addition to the lack of a postal service provider that affected the invoiced consumption in 2021, the gradual lifting of
restrictions due to the pandemic restored the operation of the majority of companies and the Industrial - Business tariff
category increased by 3.1%, corresponding to 3.1%. 0.6 million cubic meters.
Total water consumption is the sum of the following separate quantities:
• Outgoing quantity from the Water Treatment Units (MEN).
• Recorded amount of raw water supplied by water meters, connected to the external aqueducts.
• Recorded quantity of supplied refined water from external aqueducts from fast-refineries.

The decrease in revenues from the water sales and the right-of-use sewerage by -4.8% (€ -16 million) is a result of the decrease
in revenues from the General Tariff category, which constitutes 73% of total revenues.
Five (5) scales of monthly consumption are applied in invoicing of water with general tariff, based on the principle of gradual
invoicing, according to which, the more water is consumed, the higher the unit sale price is, which corresponds to the revenue

EYDAP-Greek State Agreement
On December 24, 2021, the Extraordinary Shareholders’ General Meeting of EYDAP was held which, with a positive vote of
99.96%, ratified the decision of the Board of Directors to sign the contract with the Greek State in which are defined, the terms
of renewal of the exclusive right for water supply and sewerage services, granted to EYDAP SA until 31.12.2040 and for the
signing of the contract for the operation and maintenance services of the External Water Supply System (E.W.S.S.) for three (3)
years. With the ratification of the agreement between EYDAP and the Greek State, the sale price of raw water from the Greek
State to EYDAP is determined, for the next 20 years, at a price about 40% lower than the previous one in force for the period
2004-2013.
The setting of a fair and reasonable price for raw water for the next twenty years, is a determining factor for the Company's
business plan and now provides a stable pricing environment for its consumers, but also a clear picture for investors who want
to support the company in its demanding investment plan and its transformation. The fact that EYDAP is able to recover the
amount payable of € 157.2m concerning the period 2013-2020 within the period of validity of the contract of article 114 of Law
4812/2021, contributes to the further positive evaluation of the development for the Company.
With the signing of the two contracts, a long-standing issue was finally settled, a fact that now allows the Company to have long-
term visibility and gives it the opportunity to implement its demanding strategic plan, for the benefit of all parties involved. This,
in essence, means the possibility of streamlining operating costs, accelerating the implementation of the investment program,
improving the services provided, expanding the activities and the customer base, participating in activities outside the area of
responsibility if regulations are made and an overall positive future for EYDAP.
All relevant documents (draft contracts, opinion letters, JMD) are posted on the corporate website www.eydap.gr.
New Regulatory Framework
The signing of the new contract with the Greek State, which has retroactive effect from 1/1/2021, places the Company in a new
regulatory framework under JMD 135275/2017, Government Gazette 1751/Β/22-5-2017 "Approval of general water service
pricing and pricing rules. Method and procedures for recovering the cost of water services in its various uses ", based on the
provisions of article 3 par. 1 of law 3199/2003 (A’ 280) "Water protection and management - Harmonization with Directive
2000/60/EC of the European Parliament and of the Council of 23-10-2000 ".
The purpose of JMD 135275/2017 is the approval of general rules for costing and pricing of water services for various uses and
rules and measures to improve these services, as well as defining the procedures and method of recovering the cost of these
services, including environmental costs and of water resource costs, , according to article 12 of law 3199/2003, as in force and
article 8 in combination with article 12 of p.d. 51/2007, as in force, in order to achieve the sustainable use and the improvement
of the water condition, in accordance with the environmental objectives of article 4 of the above p.d. and to ensure the
constitutionally guaranteed public character of water as a social good absolutely necessary for human life.
In particular, the main objective of the JMD is to ensure:
(a) that water pricing policy provides sufficient incentives for users to use water resources efficiently; and,
(b) adequate contribution of different water uses to recovering the cost of water services at a rate defined in approved
river basin management plans taking into account, where appropriate, the social, environmental and economic impacts
of the restoration as well as geographical and climatic conditions.
EYDAP sent on January 28, 2022 a letter to the Ministry of Environment and Energy, as the Competent Authority for the
implementation of the general rules of costing and pricing of water services, in order to answer specific questions about the JMD
to be implemented the new regulatory framework by EYDAP. In the response received by the Company on April 14, 2022, it is
stated that "the task of monitoring and controlling the implementation of the policy of costing and pricing of water services in
accordance with the provisions of JMD 135275/2017 (B '1751)" Approval of general costing rules and pricing of water services.
Method and procedures for recovering the cost of water services in its various uses" by water service providers, such as EYDAP,
will be assigned to an independent regulatory authority which will be established for this purpose.
This is a reform that has been included as a milestone in the Recovery Facility with a time frame for the relevant legislative
framework to be adopted by the end of 2022. This independent authority is very likely to be integrated as a new address in an
existing independent authority to facilitate its staffing and operation, which is expected to be complete within the first half of
2023."
The reform seeks to strengthen and optimize water management through the establishment and operation of a National Water
Regulatory Authority. The Authority will assume clear and specific responsibilities and responsibilities, which will arise as a result

Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
27
of study and extensive consultation with all interested parties. The operation of the Authority will be based on Directive
2000/60/EC, as incorporated into national law. The new Authority is expected to strengthen the institutional framework and
oversight the sector, including streamlining water pricing policy under "the polluter pays" principle, and ensuring the
sustainability of water services in Greece.
The response of the Ministry of Environment and Energy also states: "We remind you of the validity of the recent legislative
regulation (Article 114 Law 4812/2021) according to which" The validity of the invoices of EYDAP SA is extended for the provision
of water services that it offers to its consumers, which have been approved by the joint decision D6/2027/16.12.2013 of the
Ministers of Finance, Transport and Networks and Environment, 2Energy and Climate Change (B` 3188), for the period from
1.1.2019 until the approval of the new invoices based on the new contract, according to par. 2». Therefore, any issues of over-
recovery or/and under-recovery in each regulatory period will be addressed in accordance with the above one hundred and
fourteenth article of Law 4812/2021 and the provisions of JMD 135275/2017, with the approval of the new invoices of water
service suppliers.»
The new invoices that will be formed will enable EYDAP to recover, among other things, the cost of raw water and the increased
energy costs.
Final solution in the distribution of bills
In November 2021, EYDAP gave a final solution to the issue of the provision of postal services, which due to the obligation of the
Company to comply with Law 4412/2016 "Public Procurement of Works, Supplies and Services", led to time delays in
appointment of a postal service contractor and consequently in the suspension of issued bills, which temporarily affected the
pricing of the Company's customers. The suspension of billing due to the lack of a postal service provider resulted in a delay in
revenue invoicing. The Company temporarily restarted the daily issue of bills from 16.06.2021 and definitively on November 8.
On November 15, the distribution of the bills to the consumers started.
The Company through legislative regulation (law 4850/2021), ensured that the contracts for the provision of postal services
between EYDAP SA and the companies ELTA SA and ACS P.R.E.U. respectively, are automatically extended with the same terms
and conditions, either from their expiration or from the exhaustion of their financial object, until the signing of a new contract
with the contractor that will result from the completion of the relevant tender procedure. The Court of Audit also accepted the
revocation appeal filed by EYDAP, rejected as inadmissible the intervention exercised by ACS and ruled that the signing of a
contract with Hellenic Post SA can proceed. The contract of EYDAP with Hellenic Post signed in December 2021 with duration of
2 years.
EYDAP, recognizing the inconvenience created to the consumer public by the delay in the delivery of the water bills, proceeded
to extend the payment period of the bills. For this reason, the smoothing of receipts was achieved in a greater depth of time as
shown in the diagram below. Nevertheless, the Company managed to respond successfully both in terms of communication and
revenue, resulting in the normalization of revenues and the dynamics for a better course in 2022. From April 2022, the extension
in the payment of bills ceased to apply.

Immediate response to water supply problems due to fires
EYDAP SA immediately responded to the problems caused by the serious fires in August in areas of Attica. The temporary
water supply problems (pressure drop) observed in Municipalities of Eastern and Northern Attica, were due exclusively to
lack of electricity, which EYDAP dealt with by setting up backup supply systems.
Impact of energy crisis
Electricity consumption in 2021 amounted to 26.2 million euros, recording an increase of 18.8% or 4.2 million euros compared to
2020 where consumption amounted to 22 million euros. Gas also increased by 141% from 280,000 thousand euros to 680,000
thousand euros in 2021. Consumption of oil and gasoline is not significant, but due to the change in the share of vehicles-diesel
vehicles, diesel increased in 2021 by 85% from 147.6 thousand euros to 273.1 thousand euros while the supply of gasoline
decreased by 21.4% from 70 thousand euros to 55 thousand euros. The Company maintains contracts for the supply of unleaded
gasoline with a fixed profit margin for the supplier, while the price is defined as the current price per liter as announced by the
Hellenic Refineries on the day of delivery.
However, the ongoing energy crisis combined with the geopolitical crisis in Ukraine has created an unfavorable situation
regarding the increase in costs along the production chain. From January 2022, the state subsidy for the Medium Voltage
started, specifically to €65/MWh, therefore the cost of electricity for the Medium Voltage is estimated at €220/MWh and for the
low at €240/MWh. Based on current prices and state subsidies, energy costs for 2022 are projected to reach 43.4 million euros,
increased by 69.5%.
After the continuous price increases of electricity prices, and to reduce operating costs, EYDAP SA:
1. It is in the process of finding an electricity supplier through a tender, to reduce supply costs (more competitive energy and
power billing prices and bigger discounts).
2. It has launched studies and competitions in its energy-intensive facilities for the replacement of old machines, such as pumps,
with more energy efficient ones.
3. It plans to install energy control systems (monitoring) of the facilities to improve their energy performance.
4. It has launched tender procedures for the creation of Photovoltaic Power stations with energy offset, to reduce the total
consumption of electricity.
Regarding the existing Renewable Energy Sources, the current contracts for both Micro-Hydropower Plants as well as for the
existing PPS 1.97 MW, relate to fixed prices.
EYDAP in the context of the utilization of renewable and alternative energy sources has developed:
• Power generation facilities from small hydroelectric projects installed in its aqueducts and in WMC Psitalia.
• Thermal and electricity installations, utilizing the biogas produced by the treatment of sludge in the urban wastewater
treatment plants.
• Photovoltaic power station at the facilities of MEN Acharnes.
• Commencement of installation of low-consumption street lighting lamps in extensive outdoor areas of EYDAP
The contribution of RES to the total consumption: 47.5%

the materiality analysis carried out by the Company, the factors related to the ability of EYDAP to create value were determined
and are, therefore, essential for the company and its shareholders. EYDAP is the first public company to incorporate the SASB
standards in the Sustainability Report, a fact that demonstrates the Company's commitment to full and continuous
harmonization with new practices.
The transformation that is being attempted lays the foundations for the next 20 years through the modernization of operations,
the business upgrade and the utilization of resources.
In 2022, the Company will continue its investment program and the effort for greater absorption, with the main goal of
sewerage projects in Eastern Attica, 4 of which have already begun to be implemented.
EYDAP from 2022 becomes a growth actor with significant investments in green and digital transition. The Company aims to
achieve "zero carbon water", i.e. to operate the water cycle with zero carbon footprint. The Company has conducted a study
which identified further development actions, based on the diffusion of know-how and the zero carbon footprint policy that
increase the value of EYDAP and give the opportunity to offer to the rest of Greece.
With regard to the conflict in Ukraine, it is a fact that geopolitical instability is being created with macroeconomic consequences
at both national and pan-European and global levels, the extent of which cannot yet be estimated. EYDAP is not active outside
Attica, therefore it is not directly exposed. Nevertheless, unfavorable developments in the energy sector and raw material prices,
which have been increased by the situation in Ukraine and the wider macroeconomic impact, are expected to influence market
trends and increase the risk of inflationary pressures. The inelasticity of the product is expected to be a bulwark against these
pressures, while the most vulnerable invoice category is the Industrial/Corporate one due to greater market exposure.
In addition, the geopolitical crisis is likely to negatively affect the course of construction projects of the investment program due
to the inability of contractors to meet the increased prices of fuel, materials and raw materials.
The Company takes care of the adequacy of raw materials and is not expected to have a problem in the basic water supply and
sewerage operations but also in general in its supply chain.
MAIN RISKS AND UNCERTAINTIES
The Company manages its capital in such a way as to meet its objectives, as provided in paragraph 4a of Article 1 of Law
2744/99. Moreover, according to paragraph 8 of the same Article, it is prohibited to establish a right-of-use fixed assets, which

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
36
are used for the exercise of its activities related to the provision of water supply and sewerage services. It is to be noted that
according to Article 5 of the same Law there is no recovery debt enforcement of EYDAP assets used to exercise its operations
related to the provision of water supply and sewerage services.
The Company currently has no loan liabilities either long-term or short-term. After its listing on the stock exchange in 2000 and
until 2013, the Company had mainly short-term borrowings, in order to meet its operating obligations due to unpaid water bills
from certain municipalities and other public entities.
The Company maintains sufficient capital in order to serve its business objectives and to apply the appropriate dividend policy.

Financial Risk Management
Risk management is processed by the Company’s pertinent Departments which operate under certain rules which have been
approved by the Board of Directors.
The Board of Directors sets the objectives, defines the policy, and selects the risk management framework, the implementation
of which is assigned to the Company's executives. The existence of a risk management framework is of central importance and
the monitoring process is structured, continuous and consistent.
(a) Credit Risk
The Company’s exposure with respect to the credit risk is limited to the financial assets which at the reporting date of the
Financial Statements are analyzed as follows:

Trade and other receivables are included in receivables from private clients for which there is a relative risk, which is limited by
measures and actions taken by the competent directorates. The actions concern the assumption of measures in order to deal
with the arrears of due liabilities and the provision of facilities for their repayment.
For the category of local government liabilities, the Company examines the possibility of collecting arrears through the signing of
contracts (network management or settlements) or through regulatory arrangements.
The Group and the Company have revised the methodology for measuring the impairment of financial assets in accordance with
IFRS 9.

It is noted that the repaid amount of the installments and of the arrangements with private customers on 31.12.2021 stands at
Euro 7,575 k compared to Euro 11,586 k recorded in the corresponding period last year and is not included in the balance of
private customers, in the time analysis table.
The Department of Revenue & Trade Receivables Management, as well as the Department of Special Customers Management,
continuously monitor the claims of the Company, either separately or based on groups (invoice codes, customer categories) and
incorporate this information into the credit risk control procedure.
With regard to credit risk management, the Department of Collection Enforcement of the Legal Services Division reviews on
constant basis and settles via judicial procedures (LD 356/1974 “Code for the Collection of Public Revenues”) overdue
receivables concerning water supply, utilization rights and property connection rights from retail customers and local
government authorities (OTA).
The cash and cash equivalents are subject to an impairment test in accordance with the requirements of IFRS 9 and the
estimated impairment loss is not judged as significant. Credit risk management is carried out by aggregating the largest part of
the Company's assets into the Bank of Greece (approximately 60%) and by limiting the exposure to other credit institutions
(mainly systemic banks).
None of the financial assets has been placed as collateral or in any other form of credit insurance.
Correspondingly, the Company has not assigned to third parties as a form of guarantee financial instruments through Assets.
(b) Liquidity Risk
The liquidity risk is being managed by the preservation of sufficient cash available and by the assurance of bank credits for use.
There is no liquidity risk due to the existence of sufficient cash reserves which can cover the current operating and investment
needs.
The following table analyses the Company’s financial liabilities which are classified in groups according to their expiration date
which are calculated according to the time balance from the balance sheet date until the contractual arrangement expiration
date at non-discounted values.

c) Market Risk
Market risk is related to the Company's equity portfolio, which is a long-term, strategic investment and as a result is limited to
pre-defined Position Limits.
(d) Regulatory Risk
The signing of the new contract with the Greek State, which has retroactive effect from 1/1/2021, places the Company in a new
regulatory framework under JMD 135275/2017, Government Gazette 1751/Β/22-5-2017 "Approval of general water service
pricing and pricing rules. Method and procedures for recovering the cost of water services in its various uses. ", Based on the
provisions of article 3 par. 1 of law 3199/2003 (AD 280)" Protection and management of water - Harmonization with Directive
2000 / 60 / EC of the European Parliament and of the Council of 23-10-2000 ".
The objective of JMD 135275/2017 is the approval of general rules for costing and pricing of water services for various uses and
rules and measures to improve these services, as well as defining the procedures and method of recovering the cost of these
services, including environmental costs and the cost of water resource, according to Article 12 of Law 3199/2003, as effective
and Article 8 in combination with Article 12 of p.d. 51/2007, as effective, in order to achieve the sustainable use and the
improvement of water conditions, in accordance with the environmental objectives of Article 4 of the aforementioned p.d. and
to ensure the constitutionally guaranteed public character of water as a social asset absolutely necessary for human life.
In particular, the main objective of the JMD is to ensure:
(a) that the water pricing policy provides sufficient incentives for users to use water resources efficiently; and
(b) an adequate contribution of miscellaneous uses of water to the recovery of the cost of water services at a rate specified in
the approved river basin management plans taking into account, where appropriate, the social, environmental and economic
impacts of the rehabilitation as well as the geographical and climatic conditions .
EYDAP has sent since January 28, 2022 a letter to the Ministry of Environment and Energy, as the Competent Authority for the
implementation of the general rules of costing and pricing of water services, in order to answer specific questions and launch the
necessary actions to define the new regulatory framework. In the response received by the Company on April 14, 2022, it is
stated that "that the task of monitoring and controlling the implementation of the policy of costing and pricing of water services.

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
39
Method and procedures for recovering the cost of water services in its various uses "by water service providers, such as EYDAP,
will be assigned to an independent regulatory authority which will be established for this purpose. This is a reform which has
been included as a milestone in the Recovery Fund with a time horizon of the adoption of the relevant legislative framework at
the end of 2022. This independent authority is very likely to be integrated as a new management in an existing independent
authority in order to facilitate its staffing and operation, which is expected to be complete within the first half of 2023. "
The reform seeks to strengthen and optimize water management through the establishment and operation of a National Water
Regulatory Authority. The Authority will assume clear and specific responsibilities, which will arise as a result of study and
extensive consultation with all stakeholders. The operation of the Authority will be based on Directive 2000/60/EC, as
incorporated into national law. The new Authority is expected to strengthen the institutional framework and oversight of the
sector, including streamlining water pricing policy under the "polluter pays" principle, and ensuring the sustainability of water
services in Greece.
The response of the Ministry of Environment and Energy also states: "We remind you of the validity of the recent legislative
regulation (Article 114, Law 4812/2021) according to which" The validity of the tariffs of EYDAP SA is extended for the provision
of water services it offers to its consumers, which have been approved by the joint decision D6/2027/16.12.2013 of the
Ministers of Finance, Transport and Networks and Environment,Energy and Climate Change (B` 3188), for the period from
1.1.2019 until the approval of the new tariffs based on the new contract, according to par. 2. ». Therefore, any issues of over-
recovery and / or under-recovery in each regulatory period will be addressed in accordance with the above one hundred and
fourteenth article of Law 4812/2021 and the provisions of JMD 135275/2017, with the approval of the new tariffs of water
service providers. »
The new tariffs that will be formed, will enable EYDAP to recover, among other things, the cost of untreated water and the
increased energy costs.
(e) Risk due to COVID-19 Pandemic
On March 11, 2020, the World Health Organization officially designated the coronavirus (Covid-19) epidemic as pandemic.
Corporate Policy
The Management of the company from the beginning of the pandemic, monitors the developments, evaluates the risks and
takes the necessary actions to continue its smooth operation, the service of its customers but also the protection of its human
resources. Guided by the corporate social responsibility towards its employees and the citizens, it harmonized from the
beginning its operation with special health protocols of the National Organization of Public Health (EODY) and the legislative
provisions (Legislative Content Acts, Circulars, etc.) of State.
From the first moment, a Special Crisis Management Team (CRMC) was immediately established for Covid-19, while a Covid-19
Internal Coordinator was appointed, with the responsibility of coordinating the actions in case of a case in the Company.
Individual protection means (antiseptics, masks, gloves) were provided in all services and facilities, while where possible, the
rotation work is applied remotely. Regular disinfection is applied in all workplaces, while emergency disinfections are performed
in case of a case.
For the protection of the customers, the Company encouraged the consumers to carry out their transactions or requests through
the digital channels of the Company, drastically limiting the attendance at the Regional Centers.
EYDAP maintains contracts with private diagnostic laboratories for the control of its employees and their family members for the
better management of the in-service dispersion.
Another important parameter in dealing with the pandemic is the highest vaccination rate of the staff that reaches 85%, making
EYDAP a Covid-Free Company. The employees of EYDAP who for so many years care for and offer the most valuable goods with
quality, in the difficult period of the pandemic with a sense of responsibility and contribution to the common good, are almost all
vaccinated, offering their customers and themselves a sense of security.
In addition, the Company participates in the private certification scheme CovidShield and is committed to a series of actions
which constitute the Corporate Policy Covid Shield which is posted on the corporate website at the following link:

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
40
https://www.eydap.gr/SocialResponsibility/BusinessPractice
For the management system applied by EYDAP, it received certification from the international certification organization TUV.
Consumption
Consumption was not affected in 2021 by the pandemic.
Investment program-Supply chain
The absorption of the investment program in 2021 amounted to 57.75%, compared to 2020 where the absorption was 55.42%
(on the annual budget). There was no significant issue in the supply of raw materials.
Earnings
The Company monitors on a continuous basis the evolution of receipts and overdue receivables, in order to take the appropriate
measures where needed. During 2021 the Company's revenues were not affected by the Covid-19 pandemic except by the
suspension of the accounts due to involvement in the bidding process (see Section Significant Events p.24).
Water supply – Sewerage
The Company did not face any problems regarding Covid-19 in the operation of its core business.
Customer service
During the COVID-19 period, the range of electronic services to customers was enriched through the site of EYDAP SA, who can
now make the majority of their requests electronically.
In September 2021, the upgraded application for mobile phones and tablets Eydapp was launched, through which customers,
among other things, can easily and safely pay their bill without switching to another digital environment.
Health Coverage
The staff of EYDAP and the protected members are covered healthily by the health fund of the Company and with group
insurance. During the corona virus crisis, all relevant instructions have been given to the staff and the yard prescription has been
implemented.
More information on workers 'safety measures against coronavirus can be found in the "Workers' Health and Safety" section.
(f) Risk of the Geopolitical Crisis in Ukraine - Energy Crisis
The current geopolitical crisis in Ukraine, with the consequent sanctions on Russia and the European Union, has brought
significant uncertainty to the economic environment at both national and pan-European and global levels. EYDAP is not directly
exposed in these areas, therefore there is no direct impact on its activities.
However, the geopolitical crisis, combined with the pre-existing energy crisis, has led to a further increase in energy costs, in
particular gas, which has dragged the market into price increases. It is pointed out that in general there is an increase in prices of
a variety of commodities (such as Aluminum, Nickel, Copper, Tin, Wheat, Soybean, Corn) and not only in energy products that
are at historical highs of 5 years.
In the event that this increase is passed on to some extent to the products and services used by consumers - customers and
therefore the family and business budget may be burdened and redistribution may occur in the family budget of the consumer -
customer, so there may be a lag of their debts to EYDAP.
In addition, increases in the energy sector are likely to have a negative impact on sectors such as tourism, the provision of hotel
services, which will lead to a possible reduction in consumption and revenue in the Industrial/Corporate Invoice (to those of
these companies granted). In the other invoices, due to the inelasticity of the product, the above mentioned sizes are estimated
to remain at the same levels. The wider macroeconomic implications are therefore estimated to influence market trends and
increase the risk of inflationary pressures for both our customers and suppliers.
Regarding liquidity, at present there is no impact on the Company's receipts. However, it is important to determine the
regulatory framework that will determine the new invoice according to JMD 135275/2017, Government Gazette 1751/Β/22-5-
2017 "Approval of general rules for costing and pricing of water services. Method and procedures for recovering the cost of
water services in its various uses ", In order to recover the cost of raw water and increased energy costs.
The increase in prices is likely to lead to delays and difficulties in some of the Company's projects as the prices of materials, and
therefore the initial budgets of the projects, have increased significantly between the period between the submission of the
offer by the contractor and the execution of the project. Many contractors are therefore unable to complete projects they have
undertaken or not sign new contracts they have undertaken as implementation costs are prohibitive. The contractors have
submitted requests to the Ministry of Infrastructure in order to facilitate the construction market through legislation.

Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
41
The management of EYDAP takes the necessary measures in order to minimize any consequences. Stocks of particularly critical
water supply network materials are constantly recorded and the immediate supply of materials that are deemed necessary is
carried out. At present the Company does not face any problem of insufficiency of materials or their supply.
Due to the volatility of the situation in Ukraine, it is not possible to accurately assess the economic impact. The management of
the Company monitors the developments and evaluates possible further effects on its operation and results.
The ongoing energy crisis combined with the geopolitical crisis in Ukraine has created an unfavorable situation regarding the
increase in costs along the production chain. From January 2022, the state subsidy for the Medium Voltage started, specifically
to €65/MWh, therefore the cost of electricity for the Medium Voltage is estimated at €220/MWh and for the low at €240/MWh.
Based on current prices and state subsidies, energy costs for 2022 are projected to reach 43.4 million euros, increased by 69.5%.
After the continuous price increases of electricity prices, and to reduce operating costs, EYDAP SA:
1. It is in the process of finding an electricity supplier through a tender, to reduce supply costs (more competitive energy and
power billing prices and bigger discounts).
2. It has launched studies and competitions in its energy-intensive facilities for the replacement of old machines, such as pumps,
with more energy efficient ones.
3. It plans to install energy control systems (monitoring) of the facilities to improve their energy performance.
4. It has launched tender procedures for the creation of Photovoltaic Power stations with energy offset, to reduce the total
consumption of electricity.
Regarding the existing Renewable Energy Sources, the current contracts for both Micro-Hydropower Plants as well as for the
existing PPS 1.97 MW, relate to fixed prices.
EYDAP in the context of the utilization of renewable and alternative energy sources has developed:
• Power generation facilities from small hydroelectric projects installed in its aqueducts and in WMC Psitalia.
• Thermal and electricity installations, utilizing the biogas produced by the treatment of sludge in the urban wastewater
treatment plants.
• Photovoltaic power station at the facilities of MEN Acharnes.
• Commencement of installation of low-consumption street lighting lamps in extensive outdoor areas of EYDAP
The contribution of RES to the total consumption: 47.5%
In addition, the Company completed the design of 4 PP Stations with a total capacity of 3.5 MW. Already in the process of
announcing a tender 2 of the 4 in MEN Acharnes and Polydendri with a capacity of 1.99 MW
Conventional vehicles are also gradually being replaced by electric vehicles.
(g) Risk of Climate Change
Tackling climate change is one of the great modern challenges. Scientific studies show that mitigation is directly related to the
management of greenhouse gas emissions from human activity. The EU aims to reduce greenhouse gas emissions by 80-95% by
2050 compared to 1990 levels. These objectives are achieved through compliance with environmental policies, as transposed
into national and European law.
Climate change is expected to significantly affect the hydrological cycle.
• water shortage conditions
• serious damage to critical infrastructure due to increased intensity of weather phenomena
• Less possibility of natural storage of water in snow or ice in catchments as the average temperature will increase
The pressures that will be created directly affect the companies providing water supply and sewerage services, such as EYDAP, as
there are direct effects on reservoirs and in general on water sources, infrastructure and the cities they serve.
Corporate policies and due diligence
The application of the principles of prevention and precaution in the projects and activities of EYDAP is covered through:
• Evaluation in new studies of the emission of gaseous pollutants that have a direct impact on climate change (greenhouse
effect).
• Formulation of a strategy to improve energy efficiency and reduce the carbon footprint

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
42
• Implementation of rational and sustainable management of water resources, with the parallel development of leakage
reduction programs in the water supply network and the use of new technologies for the optimal management of the network
(smart grid)
• Use of new technologies for the reuse of treated wastewater for irrigation and suburban use (projects of Eastern Attica,
operation of Hadrian Aqueduct for irrigation use, Sewer Mining)
• Energy saving - reduction of greenhouse gas emissions
• Strict observance of regulations and environmental standards in the design of water supply and sewerage projects with
reserves and safeguards against environmental accidents (accidents causing pollution)
• Selection of materials and machinery with modern environmental standards
• Studies for the protection of new infrastructures from extreme phenomena, such as floods, as a result of the increase of the
average temperature of the atmosphere.
• Electric vehicles - Gradual replacement of part of the fleet with electric vehicles aimed at switching to low greenhouse gas
emission systems
• Energy upgrade of buildings and facilities
The Company's goal is to reduce the carbon footprint to 75% in 5 years.

POST BALANCE SHEET EVENTS 2021
Geopolitical crisis in Ukraine
The current geopolitical crisis in Ukraine, with the consequent sanctions on Russia and the European Union, has brought
significant uncertainty to the economic environment at both national and pan-European and global levels. EYDAP is not directly
exposed in these areas, therefore there is no direct impact on its activities.
However, the geopolitical crisis, combined with the pre-existing energy crisis, has led to a further increase in energy costs, in
particular gas, which has dragged the market into price increases. It is pointed out that in general there is an increase in prices of
a variety of commodities (such as Aluminum, Nickel, Copper, Tin, Wheat, Soybean, Corn) and not only in energy products that
are at historical highs of 5 years.
In the event that this increase is passed on to some extent to the products and services used by consumers - customers and
therefore the family and business budget may be burdened and redistribution may occur in the family budget of the consumer -
customer, so there may be a lag of their debts to EYDAP.
In addition, increases in the energy sector are likely to have a negative impact on sectors such as tourism, the provision of hotel
services, which will lead to a possible reduction in consumption and revenue in the Industrial/Corporate Invoice (to those of
these companies granted). In the other invoices, due to the inelasticity of the product, the above mentioned sizes are estimated
to remain at the same levels. The wider macroeconomic implications are therefore estimated to influence market trends and
increase the risk of inflationary pressures for both our customers and suppliers.
Regarding liquidity, at present there is no impact on the Company's receipts. However, it is important to determine the
regulatory framework that will determine the new invoice according to JMD 135275/2017, Government Gazette 1751/Β/22-5-
2017 "Approval of general rules for costing and pricing of water services. Method and procedures for recovering the cost of
water services in its various uses ", In order to recover the cost of raw water and increased energy costs.
The increase in prices is likely to lead to delays and difficulties in some of the Company's projects as the prices of materials, and
therefore the initial budgets of the projects, have increased significantly between the period between the submission of the
offer by the contractor and the execution of the project. Many contractors are therefore unable to complete projects they have
undertaken or not sign new contracts they have undertaken as implementation costs are prohibitive. The contractors have
submitted requests to the Ministry of Infrastructure in order to facilitate the construction market through legislation.

The management of EYDAP takes the necessary measures in order to minimize any consequences. Stocks of particularly critical
water supply network materials are constantly recorded and the immediate supply of materials that are deemed necessary is
carried out. At present the Company does not face any problem of insufficiency of materials or their supply.
Due to the volatility of the situation in Ukraine, it is not possible to accurately assess the economic impact. The management of
the Company monitors the developments and evaluates possible further effects on its operation and results.
PPP tender of EWSS
In the financial statements and the presentation of the financial results of 2020, that are posted on the company’s website, it
was mentioned that the framework of the agreement with the Greek State "includes the regulation of institutional issues, such
as the capacity of EYDAP to participate in PPP tenders."
Also, in the financial statements of the first half of 2021, it was stated that ‘’with a contract between the Greek State
represented by the Minister of Infrastructure and Transport, the "EYDAP Assets Company" and EYDAP S.A., it is assigned to
EYDAP S.A. the maintenance and operation of the External Water Supply System (EWSS) of the major area of the Capital for
three years. After the expiration of this contract, the maintenance and operation of EWSS will be assigned by the Ministry of
Infrastructure and Transport to a contractor, who will be selected through a tender procedure in accordance with Law
3389/2005 (A '232), in which EYDAP intends to participate".
Based on documented studies by EYDAP and the opinion of an external legal advisor, the participation of EYDAP in the relevant
tender is possible only if the founding law of the Company is amended. It is noted that the founding law of EYDAP was made long
before the implementation of Public-Private Partnerships (PPPs) and therefore, does not provide the capacity for EYDAP to
participate in them, outside of the Attica area where it operates.
The amendment of the founding law was not made until the deadline for submission of an expression of interest file on
20/1/2022, despite the relevant actions of the Company, and therefore EYDAP cannot participate in the first (A’) phase of the
relevant tender.
It is noted that EYDAP will continue to operate and maintain the External Water Supply System (EWSS) until the end of its
relevant contract, as it has successfully done for the last 40 years, providing uninterruptedly affordable water of high quality in
Attica, taking advantage of its accumulated know-how and experience.
Decisions of the Cοuncil Of State
On February 4, 2022, the nos. 190-1/2022 decisions of the Plenary Session of the CoS which deemed unconstitutional the
transfer of the majority of the Share Capital of EYDAP SA and EYATH SA to the Hellenic Corporation of Assets & Participations by
law 4389/2016. The HCAP holds direct voting rights for 50.003% of the share capital of EYDAP and indirect voting rights for
11.33% of the share capital through the HRDF.
EYDAP has not received any relevant notification until the moment of the publication of the financial results.

614/22.02.2018), and of 1.3.2018 correction of error (GG B 697/01.3.2018) which partially revoked the decision 195/27.10.2011
(GG B’ 759) of the Interministerial Committee for Restructuring and Privatization, following the decision 1906/2014 of the State
Council Plenary Session.
The total participation rate (direct and indirect) of the Greek State has not changed.
On March 21st 2018, the Company received relevant notification from the Ministry of Finance, that the total number of indirect
voting rights controlled by the Greek State amounts to 65,319,740 (61.33%). This change in the voting rights is due to the
transfer of 53,250,001 shares of EYDAP S.A., from the Greek State to the "Hellenic Corporation of Assets and Participations S.A."
(HCAP S.A.), following the execution of an over-the-counter transaction, free of charge, on March 20th 2018, according to
paragraph 20, article 380 of Law 4512/2018, which replaced paragraph 1, article 197 of Law 4389/2016, as effective from
1/1/2018.
The total (100%) of the shares of HRADF is held by the "Hellenic Corporation of Assets and Participations S.A." (HCAP S.A.), which
now controls directly the voting rights of 53,250,001 shares (50%+1 share) and indirectly the voting rights of 12,069,739 shares
(11.33%) via HRADF. Consequently, the total percentage of voting rights (indirect and direct) of HCAP S.A. amounts to 61.33%.
The Greek State controls HCAP S.A. by 100%.
Paulson & Co. Inc. notified the Company on May 2014, that it held (indirectly) 10,648,800 voting rights since 30/4/2014, a
percentage of 9.99% of the total voting rights of the Company. John Paulson held (indirectly) 10,648,800 voting rights
corresponding to 9.99% of the total voting rights of the Company. John Paulson controls Paulson & Co. Inc., which manages
investment funds. Under this role it exercises the voting rights in the Company. Until 31.12.2020 there has been no notification

F. NOTIFICATIONS RELATED TO ARTICLE 8 OF TAXONOMY REGULATION
C. ENVIRONMENT
C.1 SUSTAINABLE MANAGEMENT OF NATURAL RESOURCES/WATER SOURCES
(material issue)
Main non-financial risks
Natural resources are defined as all the primary and basic goods provided by Nature. The rational use and exploitation of
natural resources without burdening the environment, while at the same time caring for and protecting the environment, is part
of the company's corporate responsibility and a vital factor for its growth.
Water is one of the most important natural resources for the existence of life; it is an irreplaceable and quantitatively limited
good.
The ever-increasing demand for water worldwide, man-made water pollution and climate change are some of the risks we face
today, which have led to the need for holistic, preventive and consistent management of water resources.
The main axis of EYDAP’s Sustainable Development is the Sustainable management of the water cycle and the general reduction
of the company’s environmental footprint. Being responsible for providing water supply services to approximately 40% of the
Greek population and as an organisation with a high standard of know-how in matters of water resource management, the
Company ensures the rational management of these resources by constantly integrating new technologies into its activities.
Corporate policies and due diligence
Outcomes of these policies and non-financial key performance indicators
SUSTAINABLE MANAGEMENT OF RESERVOIRS
EYDAP is supplied raw water exclusively by the Greek State at the entrance to the Water Treatment Plants, the only exception
being the Mavrosouvala boreholes, which are owned by EYDAP. The management of reservoirs primarily aims at ensuring the
quantitative and qualitative sustainability of the resource.
The raw water comes from the surface water resources of the drainage basins of Marathonas, Yliki, Mornos and Evinos, and
the backup underground water resources which can be utilized through the operation of boreholes depending on the
availability of underground resources and the policies regarding their use.

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
96
EYDAP ensures the protection of reservoirs by:
• strictly adhering to legislation (Health Regulation A5/2280/1983) “on the protection of water used for the water supply of the
Athens region against pollution and contamination” and to Presidential Decree 51/2007 on establishing measures and
procedures for the integrated protection and management of water, in compliance with the provisions of Directive
2000/60/EC;
• inspecting the works and activities in the protection zones of the reservoir drainage basins;
• performing sample measurements to test the quality of the water in the reservoirs;
The applied water resource management methods are defined by:
• Science-based rationality
• Efficiency: as they make optimal use of water resources
• Sustainability: as they do not cause the exhaustion of water resources in the future by covering current needs
(the issue is analyzed in section “Access to Clean Water, Supply & Water Network Coverage” of the same Report).
SUSTAINABLE MANAGEMENT OF WATER SUPPLY NETWORK & ASSETS (SMART GRID)
With the primary goal of ensuring the Sustainability of the water resource and covering water supply needs, EYDAP manages
water demand by developing leakage reduction programs (pressure management, water zones, immediate repair of
failures/breaks, etc.).
As part of the reform being implemented with the aim of modernizing and optimizing network and asset management, the
Company is in the process of developing a “Smart Grid”. This smart grid regulates and controls the production and distribution
of the resource, and aims at forming a smart connection between consumers and production, the ultimate goal being to create a
more cost-efficient and safe network with reduced losses. By reducing leakages and by optimizing and automating the
management of water resources, the smart grid ensures the sustainable management of these resources (the issue is analyzed in
the section titled “Reliable Water Network” in the same Report).
TIERED PRICING
Tiered pricing acts as a deterrent to the waste of the natural resource and raises awareness among consumers to apply rational
use of the resource.
PROTECTION OF THE MARINE ENVIRONMENT
The proper operation of Wastewater Treatment Plants (Psyttalia, Metamorfosi, Thriasio WWTPs), the observance of strict
outflow specifications, the control, constant maintenance and upgrading of WWTPs using high technology means, as well as the
development of the sewerage network all contribute to maintaining the good condition of marine ecosystems (the issue is
analyzed in section “Protection of the Marine Environment” in the same Report).
EAST ATTICA PROJECTS – REUSE OF TREATED EFFLUENTS
The planning of the construction and operation of integrated wastewater management systems in East Attica includes the reuse
of treated effluents for irrigation purposes through the use of cutting-edge technology, in full compliance with the current
institutional framework on reuse. These projects are a strategic choice for EYDAP and have a significant impact on the
enrichment of the groundwater aquifer, the protection of the marine environment and the conservation of the precious
resource of water. (the issue is analyzed in the section titled “Sewerage Projects in East Attica” of the same report).
MONITORING AND PROTECTION OF SURFACE WATER
After the successful completion of the INTCATCH European research program, EYDAP has at its disposal two autonomous
robotic boats which have come to reinforce its existing program for the monitoring and protection of water quality.
These robotic boats highlight EYDAP’s leading position in the Water Supply and Sewerage sector when it comes to protection of
the Marine Environment, putting it in a position to convey its know-how to all Public and Private Organizations involved in the
Management and Protection of Water Resources (Management Agencies, Municipal Water Supply and Sewerage Corporations,
Regions, Municipalities, Research Institutes, Universities, etc.).
The use of robotic boats for the second year in a row has shown that they can contribute to a better and more complete quality
control of the Reservoir, given that in the case of an indication of potential pollution caused by human activities and/or natural

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
97
processes, the boats can rapidly take operational action across the entire expanse of the lake and promptly identify the point
of inflow of the pollutant.
In 2021 inspections with autonomous vessels continued in all EYDAP’s reservoirs and more than 250,000 readings were
collected along a total of more than 90 kilometres around the Reservoirs.
The results were evaluated in real time, both on site (via suitable mobile applications) and digitally, and were validated through
the Reservoir Monitoring Reports. The results confirmed their very good oligotrophic-mesotrophic state. The boats are
equipped with sensors for measuring and recording environmental parameters such as chlorophyll, conductivity, dissolved
oxygen, pH, temperature, nitrates, total nitrogen and phosphorus, while they also have a suitable autonomous sampling system
for collecting water from points that are not otherwise accessible. All the above parameters remained at normal levels, which
are typical for Water Reservoirs, and were in line with the results of EYDAP’s existing monitoring program.
EYDAP’s aspiration and strategic objective is to consolidate its cooperation with all stakeholders, by providing services for the
protection of surface waters and the integrated management and sustainable development of water resources.
SEWER MINING
The reuse and recycling of water is gaining ever greater momentum in the Sustainable Development of cities, thus highlighting
the central role played by water in the triptych of water - energy - matter, which is the focus of circular economy.
In the context of applying the principles of circular economy, EYDAP implements research projects aiming at decentralized reuse
by utilising liquid wastewater directly from the sewerage network with the use of the sewer mining technique. Sewer mining
technology essentially constitutes a mobile wastewater treatment plant that can extract wastewater from local sewers and
treat it on the spot, supplying water ready for use at the points of demand, even in dense urban environments.
EYDAP is pioneering in Greece. Since 2021 it is responsible for the operation of two Model Sewer Mining Plants by applying new
technologies for the treatment and production of recycled water.
The first Plant has been set up at the Athens Municipality Plant Nursery, in the framework of the European NEXT-GEN research
project, as a result of the cooperation between EYDAP, the National Technical University of Athens, the Chemitec company and
the Municipality. The Plant produces 25 m3 of recycled water on a daily basis, which is tested by the Chemical Laboratory for
Research and Environmental Applications of EYDAP in terms of its harmonization with the requirements of the legislation, and is
used for the irrigation of expanses of ornamental plants on the Municipality’s premises in Goudi.
The second plant has been operating since 2016 on the Company’s premises in Metamorfosi, following the successful
completion of the DESSIN project, and the recycled water is used for the irrigation of the surrounding area.
The social and environmental benefits of Sewer Mining technology are remarkable, since it helps to achieve the following:
• Reduction in the quantities of treated effluents released to water bodies;
• Reduction in the amount of water demand from surface and underground aquifers, and thus conservation of their reserves;
• Possibility of enriching underground aquifers;
• Reduction in the cost of transporting waste water;
• The possibility of creating and maintaining urban green areas, important centres for quality of life in the city, and
consequently improving the aesthetic landscape of the area, without using up drinking water for their irrigation;
• Possibility of supplying reclaimed water for irrigation purposes in areas facing water scarcity problems (islands).
HADRIAN’S AQUEDUCT AS A WATER RESOURCE
For the purposes of enhancing resilience and Sustainable Development, and in the framework of the holistic utilization of
Hadrian’s Aqueduct, EYDAP actively participates in:
• the utilization of non-potable water to cover local irrigation needs;
• the connection of the monument to contemporary inspirational projects for the Municipalities it runs through;
• its promotion as a Cultural Heritage Monument (section on the “Management of Cultural Heritage” in the same Report).
CULTURAL HIDRANT Pilot Program
EYDAP is participating as a partner with the Municipality of Halandri in the creation of a non-potable water supply network for
irrigation purposes, as part of the UIA05-255 CULTURAL HIDRANT program co-financed by the EU with a total budget of
EUR 3,133,296.
The program includes the:

• EYDAP created the “Drop a Message” application - with the registration of 81 users - in order to promote the possibilities
offered by the use of non-potable water;
• 45,000 newsletters on the program and on the planning of the new non-potable water supply network were sent to all
EYDAP customers in the Municipality of Halandri. At the same time, a public survey on water needs was conducted (41
participants).
Collaboration with Agencies for the holistic management of Hadrian’s Aqueduct
In April 2021, with the aim of achieving the integrated utilization of Hadrian’s Aqueduct, EYDAP participated in the design of the
Integrated Territorial Investment proposal coming under the Sustainable Urban Development (SUD) axis of the NSRF 2021-2027,
and started a collaboration with the Ministry of Culture and Sports, the Region of Attica and the Municipalities located along the
route of the underground aqueduct from the foothills of Mount Parnitha to Kolonaki, covering a total stretch of over 20km.
The aim of the Program is to:
• protect the monument
• reduce the average temperature in the city
• use the water to cover local irrigation needs and connect the monument to inspirational works in the regions it runs
through
• align the project with the needs of the local economy, culture, education, etc.
At the same time, EYDAP has undertaken to:
• investigate the quantity and quality of the available water resource in Hadrian’s Aqueduct;
• restore and highlight the visible points of Hadrian’s Aqueduct (this involves 39 shafts, in collaboration with an expert civil
engineer-speleologist);
• install information signs and railings around shafts and open points of access, such as the inclined gallery at the Olympic
Village.
Links to the scientific community
• The Company provided material and scientific support for a master-level dissertation titled “Utilisation of non-potable
water from Hadrian’s Aqueduct in the urban fabric”.   
• EYDAP’s proposals for highlighting the layout of the underground Hadrianic Aqueduct through “green” urban planning
served as the subject of a workshop in the framework of the Infrastructure Planning Master Programme offered by the
New Jersey Institute of Technology in the USA.
• These Proposals have been included in the foundational material for the topic of Hadrian’s Aqueduct in an
Interdepartmental Postgraduate Study Programme between the National and Kapodistrian University of Athens, the
University of Patras and the University of the Aegean, which was completed successfully. 
CIRCULAR ECONOMY
The transition to circular economy is a necessary condition for the protection of natural resources and the environment. (the
issue is analysed in section titled “Circular Economy – Management of Liquid and Solid Waste” in the same Report).
ENVIRONMENTAL COMPLIANCE
EYDAP operates in compliance with environmental legislation.
• It complies with the approved environmental terms for all its facilities.
• The relevant environmental licensing procedure is followed for each new project or modification of the existing ones.
• A Decision of Approval of Environmental Conditions has been issued for each Wastewater Treatment Plant (WWTP) and
Water Treatment Plant (WTP) with their accompanying projects. The same applies to all the facilities of the External Water
Supply System.
• For all the projects and activities of the company, there are decisions in force for approval of environmental conditions.

C.2 PROTECTION OF BIODIVERSITY
Main non-financial risks
The basic parameter in the sustainable management of water resources is the preservation of biodiversity.
Through the management of the water cycle, EYDAP protects the aquatic ecosystems in the areas in which it exercises its
activities.
Corporate policies and due diligence and Results of such policies and non-financial key performance indicators
Due to the fact that human activities are strictly regulated, lakes are developing into significant wetland ecosystems, which
support protected avifauna species, interesting ichthyofauna and unique lakeside vegetation.
The basic role of EYDAP reservoirs is to store high-quality water for the capital’s water supply; however, they also constitute
significant wetlands:
• The natural lake of Yliki, a source of water abstraction for the Water Supply System of Attica, forms part of the Natura 2000
network of protected areas.
• The artificial lake of Marathon is the first reservoir of the Attica water supply system and a significant wetland.
• The Mornos and Evinos Reservoirs are important wetland ecosystems.
WATER FOR THE ECOSYSTEM - “ECOLOGICAL WATER SUPPLY”
For the purpose of preserving the continuity of wetland ecosystems, EYDAP has appointed researchers, in collaboration with the
National Technical University of Athens, to explore the possibility of maintaining “ecological water supply” in the river
ecosystems downstream of dams. Maintaining this minimum required flow is necessary according to the law, environmental
provisions and contemporary international trends in the environmental management of reservoirs.
The necessary interventions have already been implemented on the Marathon dam in order to increase the residual supply
downstream of the dam to 25 l/sec, according to the recent Technical Environmental Study implemented by EYDAP.
The river ecosystem downstream of the Mornos dam is in good condition due to the constant flow of surface water over the
river bed. EYDAP has completed the systematic monitoring of the ecological and chemical condition of the river ecosystem by
implementing a three-year hydromorphological, physicochemical, biological and chemical measurement program, in accordance
with the specifications of Water Framework Directive 2000/60/EC and the YD04 Water Management Plan set out in the
Technical and Environmental Study of the Mornos Dam, which was implemented by EYDAP S.A. The above monitoring indicated
that the river ecosystem downstream of the Mornos dam is in good ecological and chemical condition.
An “ecological supply” of 1m
3
/sec has been estimated for the Evinos river, which is the newest reservoir. Consequently, the
riparian ecosystems downstream of the dam maintain their physiognomy and their significant biodiversity.
C.3 PROTECTION OF MARINE ECOSYSTEM
Main non-financial risks
Protecting the marine ecosystem is one of EYDAP’s key concerns. As such, the Company institutes procedures and actions that
effectively contribute to maintaining the good status of the marine ecosystem, in compliance with environmental laws and
policies incorporated into national and European law.
Taking the vitally important issue of protecting the marine ecosystem into serious consideration, EYDAP adopts measures to
ensure preparedness and be able to respond and mitigate significant negative impacts on the environment. Such measures aim
at reducing the severity and extent of these impacts. The measures arise from the Company's operation and risks for serious
accidents.
However, it is noted that the status of the marine environment of aquatic receivers also depends on a number of other factors
outside of EYDAP's remit (illegal waste disposal, maritime accidents, storm water runoff, etc.).
Corporate policies and due diligence and outcomes of these policies and non-financial key performance indicators
WWTP DESIGN & OPERATION
WWTPs constitute key environmental infrastructures that significantly protect marine receiving waters by:

• collecting and treating urban wastewater;
• monitoring the proper operation of treatment facilities, the Psyttalia WWTP, the Metamorfosi WWTP, the Thriassio WWTP,
and continually upgrading and maintaining them with high-technology means;
• complying with strict effluent specifications;
• frequent sampling
• ongoing training of Company personnel to respond to potential hazards;
to help minimize impacts and maintain the good status of marine ecosystems.
EYDAP analyses the existing status of receiving aquatic ecosystems by preparing environmental impact studies (EIS), both when
designing WWTPs and during their operation. The choice of level of treatment performed at the WWTP under design is always
based on current regulatory provisions and the quality of the receiving waters and aims at protecting their ecosystems.
The treated effluent from the Psyttalia and Thriassio WWTPs ends up in the Saronic and Elefsina Gulfs while effluent from the
Metamorfosi WWTP is discharged to the Saronic Gulf, through its main receiver, the Kifissos River. The treated effluent from
WWTPs is discharged into the sea approximately 95% free of its pollutant load.
The start of operations at the Psyttalia WWTP in 1994 was a milestone in the improvement of the Saronic Gulf marine
ecosystem, which in previous years had dramatically declined due to discharge of untreated wastewater. Studies show
continuing improvement, both in terms of physicochemical parameters and the status of the marine ecosystem. As part of
Directive 2000/60/EC and the implementation of river basin management plans, the ecological status of the Saronic Gulf, which
is the receiver of the Psyttalia WWTP, has been assessed as “good”.
Another decisive factor in protecting the marine environment is the implementation of new sewerage projects in the East Attica
areas, with integrated management of wastewater and reuse of treated wastewater for irrigation and to minimize its discharge
into the sea. These actions have an indisputably positive impact on the protection of marine ecosystems.
SYNERGIES WITH SCIENTIFIC BODIES AND DISCLOSURE OF THE WWTP’S PROPER FUNCTIONING OUTCOMES TO THE PUBLIC –
HCMR
EYDAP conducts testing and studies of the marine environment to determine the impact on bathing waters at beaches in Attica
near the WWTPs, and at the respective habitats at the discharge sites of treated urban wastewater. Environmental monitoring
takes place with frequent measurements by competent state bodies (HCMR, Ministry of Environment and Energy’s Secretariat-
General for the Natural Environment and Water, Region of Attica, Blue Flag program).
EYDAP has implemented a program to modernize its facilities and ensure that effluent quality levels are maintained as specified
in the Decisions to Approve Environmental Conditions for the WWTPs, or at even higher levels. The concentration limits of
pollutants in effluents are much lower than those required by the DAEC; significant energy savings are also realized, particularly
at the Psyttalia WWTP.
Following a tender process, EYDAP has contracted with the Hellenic Centre for Marine Research for the systematic monitoring of
the Saronic and Elefsina Gulf ecosystems, which have been identified as “sensitive receivers”. Monitoring activities include
indicators and parameters to assess the environmental and ecological status of the marine ecosystem.
With regard to the effective operation of the WWTPs, analyses of treated wastewater effluent quality at the WWTPs are the
result of laboratory analyses and are accessible to the public on the Wastewater Treatment Plant Monitoring Database
maintained by the Ministry of Environment and Energy (http://astikalimata.ypeka.gr/).
Compliance with effluent quality limits for each parameter posted for each EYDAP WWTP for 2021 is shown in the following

In 2021, as in previous years, compliance with effluent quality limits at EYDAP's WWTPs greatly contributed to the improved
status of the Saronic and Elefsina Gulf marine ecosystems.
The quality of coastal waters is also indicated by the fact that almost all coastal areas intended for bathing around the Saronic
Gulf have been awarded a “Blue Flag”, which is a symbol of environmental quality chiefly based on the assessment of marine
water quality.
The Company did not identify any incidences of non-compliance with environmental laws and/or regulations during the
reporting period.
C.4 MEASUREMENT, MONITORING & MITIGATION OF GREENHOUSE GAS & OTHER GAS
(material issue)
Main non-financial risks
Climate change is one of the greatest challenges of today. Scientific studies show that mitigation of the phenomenon is in direct
link with the management of greenhouse gas, derived from human activity. EU seeks the reduction of greenhouse gas by 80-
95%, in comparison to 1990 rates, by 2050.
Targets are realized through compliance with environmental policies, as incorporated in National and European Law and with
the enforcement of measurement, monitoring and mitigation of greenhouse gas emissions. EYDAP, in the context of corporate
responsibility records the greenhouse gas emissions since 2019.
Corporate policies and due diligence and
The Company, with environmental sensitivity, aims at the mitigation of its carbon footprint (Net Zero)

reporting of greenhouse gas emissions and removals.
2. Greenhouse Gas Protocol, WRI (GHG Protocol Corporate Accounting and Reporting Standard, Revised Edition).
Emissions in 2021 showed a reduction of 2.54% in comparison to 2020 and an increase of 2.2% in comparison to 2019.
INTRODUCTION OF THE PSYTTALIA WASTEWATER TREATMENT PLANT (PWWTP) ISINCE 2014 IN GREENHOUSE GAS EMISSIONS
TRADING SYSTEM (EU-ETS)
In compliance to legislator framework, the Psyttalia Wastewater Treatment Plant, the main effluent treatment installation,
joined in 2014 the above system. Annual Reports, verified by external accredited auditor, are submitted to the competent
National Authority (Ministry of Environment & Energy) and to the relevant Register of the EU. The difference of CO2 emissions,
in relation to base year 2014, is 2.885tn in 2021, lower than the relevant rate 3,394 tn in 2020, due to the increased
consumption of natural gas, to cover extraordinary operational needs.
As shown in the graph, in 2021 there is a decrease of emissions at a rate of 55% in relevance to base year 2014 (5,236 tn) CO
2
).
More specifically, in 2021 the increase in CO2 emissions from PWWTP is at rate of 28.18%(+) in comparison to the relevant rate
of 2020, the corresponding CO2 emissions’ increase from 2019 rate lies to 16.82%(+), while the corresponding CO2 emissions’
reduction in comparison to 2018 amounts to 9.05%(-).

The significant reduction of CO2 emissions in PWWTP is due to a series of targeted management options. More specifically in:
• Natural gas use reduction and its substitution with biogenic biogas produced at the plant by the treatment of sludge.
• Projects implementation for the increase of biogas production
• Installation of an integrated automatic power and energy management system, which allows the rational use of energy
sources.
The achievement of this reduction is the result of adequately targeted interventions and activities in the installations.

C.5 ENERGY SAVING
(material issue)
Main non-financial risks
Given that energy affects both the cost of production and service delivery and the environmental footprint, EYDAP has made
energy conservation one of the central pillars of its strategy.
The current energy crisis and the associated risks to the environmental and economic sustainability of growth require holistic
management of the issue. In order to strengthen the Corporate Resilience against further shocks and in order to protect the

104
economic resilience of both households and professionals with possible deprivation of their ability to cover the cost of water and
wastewater services, EYDAP has initiated actions from 2021 that will culminate in the following years as part of the Company's
energy transition.
To reduce the impact of the current crisis, it is continuously evaluating and adjusting its processes and monitoring developments.
Corporate policies and due diligence and Outcomes of these policies and non-financial key performance indicators
The utilization of biogas from the WWTPs as well as the production of energy from the Small Hydroelectric Power Plants (SHEPP)
and the Photovoltaic Plant contribute to the achievement of the national target of increasing the production of energy from
Renewable Energy Sources, as well as to the optimization of the company's energy balance.
In the context of the utilization of renewable and alternative energy sources, EYDAP has developed:
• Energy production facilities from small hydroelectric power plants installed in its aqueducts and at the WWTP of Psyttalia.
• Combined heat and power plants, using biogas produced from the treatment of sludge in the wastewater treatment plants.
• Photovoltaic station at the facilities of the Acharnai WTP.
BASIC RES STATIONS OF EYDAP
PHOTOVOLTAIC STATION IN ACHARNAI
In the direction of producing energy from renewable sources and reducing its carbon footprint, the company has installed a
photovoltaic (PV) power plant with a capacity of 1.9712 MW at its facilities in the Municipality of Acharnai, for the purpose of
selling the electricity produced.
In 2021 (January - December), energy production amounted to 3,150,587 kWh, the same level as in 2020.
SMALL HYDROELECTRIC POWER PLANTS (SHEPS)
Along the external aqueducts that transport water from the reservoirs to the refineries, small hydroelectric power plants
operate, whose energy is sold by EYDAP. The water from the aqueducts is diverted to a side canal, where a hydro turbine
converts the hydraulic energy into mechanical energy and then, via a generator, into electricity. The water is then reintroduced
into the main aqueduct, where it continues to flow.
Specifically, the operating SHEPS are:
Elikonas SHEPS with a capacity of 650 kW and a projected annual energy production of 5.000.000 kWh.
Evinos SHEPS with a capacity of 820 kW and a projected annual energy production of 4 000 000 kWh.
Kithairon SHEPS with a capacity of 1200 kW and an estimated annual production of 5 730 000 kWh.
Kirfi SHEPS with a capacity of 760 kW and a projected annual production of 5 860 000 kWh.
Mandra SHEPS with a capacity of 630 kW and a projected annual energy production of 4 900 000 kWh.
In 2021, the total energy production from the above SHEPS' will amount to 17,515,903 KWh, approximately 20% lower than in
2020 (21,962,864 kWh).
The energy produced by the SHEPS is totally dependent on the range of DEI grid instabilities, as well as on the weather
conditions and the occurring failures of the electromechanical equipment of the plants.
SMALL HYDROELECTRIC POWER STATION IN THE PSYTTALIA WWTP
In Psyttalia there is a small hydropower plant installed in the outflow pipeline, which has been operating since 2015 and whose
own electricity production reaches 2,259,287 kWh in 2021 with the corresponding value in 2020 being at the same level of
2,267,376 kWh. The variation of the power generation from this plant in the outflow pipe of the Psyttalia WWTP is due to the
annual variation of the wastewater flow.
TOTAL SHEPS
Attached is a graph showing the annual production of the 5 SHEPS and the hydroelectric output of WWTPS

BIOGAS
The biogas produced in the digesters of the Psyttalia WWTP is used as fuel:
• In internal combustion engines for combined heat and power.
• In the thermal drying plant of the dehydrated sludge.
• In the boiler room of the digestion unit for sludge heating.
• In the steam generating unit for the production of steam (for the sludge thermal hydrolysis unit).
At the Metamorphosis WWTP, the digester biogas is used only as thermal energy.
The recoverable thermal energy of the Psyttalia WWTP for 2021 is 139.652 MWh and the Metamorphosis WWTP 3.331 MWh.
The electricity produced by biogas at the Psyttalia WWTP is 25,891 MWh.
ACTIONS IN PROGRESS TO CONSERVE ENERGY
• The Polydendri WTP has a nominal refining capacity of 200,000 m³/d. The two pumping stations for undiluted and refined
water were built in the 1970s and have been operating continuously since then with the same pumping units with very low
efficiency, resulting in high energy consumption. In the context of reducing energy consumption and ensuring the safety of
the operation of the WTP for the uninterrupted water supply of the city of Athens, a project design has been completed to
upgrade the energy efficiency of the two pumping stations by constructing new pumping stations. Specifically, the project
includes:
I. replacement of pumps with new modern high-efficiency pumps and low-loss motors,
II. construction of a new refined water pumping station building,
III. replacement of medium voltage substations with very low loss substations in accordance with the latest EU
directive,
IV. installation of a modern distribution network and motor control systems.
V. Installation of back-up power generation which will ensure the uninterrupted operation of the WTP at its maximum
capacity.
VI. Automatic control system for the operation of the pump station with installation of new SCADA.
The project is to be completed in terms of study and to be launched for implementation within 2022.
In 2021:
• The installation of low-consumption street lighting lamps in extensive outdoor areas of EYDAP began, with the future result
of lower consumption and avoiding the replacement cost of the current conventional ones, since the new ones have a 5-
year replacement guarantee.
• The design of 4 PV Plants with a total capacity of 3.5 MW was completed through the energy offsetting procedure and 2 of
the 4 PV Plants at the 1.99 MW Acharnai and Polydendri WTPs are already in the tender process, which will save money
from the reduced electricity purchase.
• The process of energy checks of EYDAP's facilities was completed and the results were submitted in accordance with the
provisions of the legislation. The conclusions and recommendations from the energy checks were sent to the Directorates
and Services responsible for implementation.
• Energy inspections were carried out in 11 EYDAP buildings receiving the official certificates. The conclusions and
suggestions from the Energy Footprint survey have been forwarded to all the Directorates and Services of EYDAP
responsible for implementation.

• The planning of the following pilot actions has started:
o Participation of EYDAP as a partner in the Energy Capability Centre, an initiative of the National Technical University of
Athens and EPISEY that will implement by 2023 the design of innovative approaches to reduce the energy footprint.
The first project concerns the design of the production of e-fuels (production of artificial fuel from green energy) for
transport.
o Optimization of the energy operation of the Metamorphosis Wastewater Treatment Plant in the framework of the
European Research Project HORIZON _ Trineflex.
o Installation of PV panels with parallel heat generation in the KEREFYT.

C.6 CIRCULAR ECONOMY- LIQUID AND SOLID WASTE MANAGEMENT
(material issue)
Main non-financial risks
Utilising material and natural resources throughout their life cycle is an important business approach to the circular economy
and a response to our commitment to environmental protection.
The continuous reduction of the amount of waste that needs to be disposed of at the end of a product's life cycle contributes
significantly to minimising its impact on the environment and human health.
As the largest water and wastewater company in Greece, EYDAP is continuously upgrading its facilities, with the aim of gradually
reducing the waste generated by its plants, by reusing by-products stemming from its production processes, recovering and
generating energy from waste, and consistently reducing its greenhouse gas emissions.
Non-application of the principles of the circular economy carries risks for the Company, such as non-compliance with the
regulatory framework, with all the legal consequences that implies, reputational damage to the Company, lack of trust of our
customers in the Company, as well as substantial financial damage to the Company.
Corporate policies and due diligence
CIRCULAR ECONOMY, WATER RESOURCES MANAGEMENT AND SLUDGE MANAGEMENT
In the water sector, participating in the circular economy and in sustainable natural resources management starts with opting
for renewable water resources, choosing energy-efficient technologies in transportation and distribution, and reusing
renewable water resources.
In the Company's Water Treatment Plants, the integrated management includes the adoption of good practices and actions that
aim to reduce the consumption of water used during treatment processes. During the production of drinking water, the water
required for cleaning the facility and for disposing of the solid waste generated during the treatment process is not wasted.
Through appropriate treatment processes, much of this water is recycled and re-introduced into the production process,
leading to its maximum utilisation, and thus minimising water losses.
SLUDGE PROCESSING IN WATER TREATMENT PLANTS
Today, at the Galatsi Water Treatment Plant (WTP), the sludge generated during the sedimentation process and filter washing is
transferred to existing tanks. Part of it then forms part of the reclaimed water, which is taken to the WTP for re-treatment, while
the rest is transferred, through the sewage system of EYDAP, to the Wastewater Treatment Centre of Psyttalia.
EYDAP invests in the upgrade of all its Water Treatment Plants and in the necessary additional projects for the treatment and
management of the sludge generated during the water purification process.
Displaying environmental awareness and responsibility, EYDAP has prioritised the optimisation of the treatment of the sludge
generated as a waste material from water treatment. With this goal in mind:
• At the Polydendri WTP, in 2019 the construction of a modern sludge management unit was completed and the unit was put
into operation. The sludge produced during water treatment is further processed. The solid waste is separated from water
and then the water enters the WTP for re-treatment. The solid sludge produced is collected and transferred to licensed sites.
• At the Aspropyrgos WTP, the maintenance and upgrade of the existing sludge processing systems was completed in 2019,
when the systems were also re-put into operation. The sludge produced as a result of the purification of raw water is further
treated. The solid waste is separated from the water and then the water enters the WTP for re-treatment. The solid sludge
produced is collected and transferred to licensed sites.

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
108
• At the Acharnes WTP, the construction of the sludge management and backwashing unit was completed in 2021. The
sludge generated as a result of the water purification process is further treated. The solid waste is separated from the water
and then the water enters the WTP for re-treatment. The solid sludge produced is collected and transferred to licensed sites.
• At the Galatsi WTP, the construction project of the sludge management unit is in the phase of awarding the final contract
to the successful tenderer. The start of construction is expected within the third quarter of 2022, with an expected
completion date in the fourth quarter of 2023.
It is estimated that the sludge treatment plants that are already in operation at the Polydendri, Aspropyrgos, and Acharnes
WTPs, together with the soon-to-be-completed equivalent unit at the Galatsi WTP will save:
✓ 4,300,000 m
3
per year
✓ of resources by reducing the energy consumption
✓ of chemical processing materials.
The sludge produced as a result of the treatment of the raw water will be further processed in flocculation tanks and end up
as the last stage in the dehydration unit. The quantities of treated sludge produced by the WTPs are recorded online on an
annual basis in the National Database of the Urban Waste Water Treatment Plants of Greece, in accordance with the relevant
legislation, and is collected by licensed companies for further utilisation, as soil improver for various crops in cases of tree
planting, for the cement industry and the ceramics industry.
CIRCULAR ECONOMY IN WASTEWATER MANAGEMENT
The integrated wastewater management of Attica is a strategic goal of EYDAP.
(The topic is discussed in detail in the chapter "Consumer Health and Safety: Sewerage Services").
Solid waste is generated during wastewater treatment, which consists mainly of wastewater pre-treatment by-products and
sludge. This is non-hazardous waste, the responsible disposal and management of which is a priority for EYDAP's stakeholders,
e.g., the local communities in the areas of the wastewater treatment plants, especially taking into account the large annual
quantities of waste generated.
At the Wastewater Treatment Plants (WWTPs), the solid waste generated during the pre-treatment phase (screening waste, grit
and large solids), as well as the primary sludge (fine solids, sludge) is landfilled.
The drying of the dehydrated sludge generated by all three WWTPs, takes place at the Psyttalia WWTP.
The entire quantity of dried product is utilised thermally by the cement industry as an alternative fuel, applying a
technologically modern, environmentally friendly, and sustainable solution.
The biogas produced at the phase of sludge refinement in both the Psyttalia and the Metamorfosi WWTPs is utilised for energy
production. Specifically:
• at the Psyttalia WWTP, the total amount of biogas produced is used in-house
• at the Metamorfosi WWTP, 70% of the amount of biogas produced is utilised.
REUSE OF RECLAIMED WATER IN THE NEW SEWERAGE PROJECTS IN EAST ATTICA
The planning of the construction and operation of integrated wastewater management systems in Eastern Attica aims at the
reuse of treated effluents. These projects are a strategic choice of EYDAP, with a significant impact on saving valuable water
resources (the topic is further discussed in the section "Sewerage Projects in Eastern Attica" within the same document).
REUSE BY DIRECT PUMPING FROM THE NETWORK (SEWER MINING)
Applying the principles of circular economy, EYDAP implements research programmes aimed at decentralised water reuse, by
using effluent directly from the sewerage network (Sewer Mining).
(The topic is further discussed in section "Management of Natural Resources/Water Sources" within the same section)

D. SOCIETY
D.1 CONSUMERS’ HEALTH & SAFETY
D.1.a WATER SUPPLY QUALITY
(material issue)
Main non-financial risks
EYDAP, as the largest provider of water services, being aware of its responsibility to millions of consumers, ensures the excellent
quality of drinking water. Through continuous investments in infrastructure projects, in technology and in training of its human
capital, EYDAP ensures drinking water quality, one of the highest in Europe, always in harmony with the existing provisions.
According to the Urban Water Atlas for Europe for 2017, published by the European Union and presenting the best practices in
European cities, EYDAP was rated with 10 (excellent) in terms of drinking water quality for the city of Athens (Urban Water
Atlas for Europe 2017, European Commission, Publications Office of the European Union, Luxembourg, pp.54-55).
In the annual international evaluation of water companies published in 2021 by the European Benchmarking Co-operation,
EYDAP’s water quality was rated with 99,846%, higher than the average scores achieved by the participating Western
European companies.
Excellent quality already starts from the main reservoirs Evinos and Mornos.
The risk of gradual degradation of water quality due to man-made activities around the main reservoirs is limited, due to their
location at high altitudes, in inaccessible, sparsely populated and very restricted areas. In addition, EYDAP ensures the protection
of its reservoirs by complying with strict legislation as it arises from Sanitary Order A5 / 2280/1983 "for the protection of water
used for water supply in the capital area from pollution and contamination and PD51 / 2007 laying down measures and
procedures for integrated water protection and management in accordance with the provisions of Directive 2000/60 / EC.
The risk of a sudden deterioration in the quality of water available to consumers can arise, however, from a natural disaster, or
from an inadvertent inflow of unsuitable substances into the water supply network, or from malicious or terrorist acts, or from a
failure of the facility.
The precautionary treatment of such risks, in addition to enhancing the good reputation of the Company, guarantees the safety
of the consumers and the resource. In addition, it prevents the imposition of fines for non-compliance with current legislation.
For all the above reasons, and in order to continuously ensure the quality of water for consumers, EYDAP has carried out an
analysis and assessment of the risks it may face in this area. The probability of occurrence is not high for any of them. For each
contingency, a relevant precautionary action plan has been prepared and implemented.
EYDAP ensures that all hazards that could potentially disrupt the quality of water entering its facilities, but mostly the water that
reaches the consumer's tap, are adequately identified and controlled through:
• Monitoring of activities in the water catchment areas
• Maintenance, supervision and operation of dams / reservoirs / aqueducts, through which water is collected and Attica is
supplied with water
• Maintenance and operation of the drinking water distribution network
• Constant quality checks of untreated and drinking water available to consumers

Corporate policies and due diligence
EYDAP ensures the implementation of appropriate water quality control procedures,:
• to meet the requirements of the Legislation and its Stakeholders.
• to apply good laboratory practices and appropriate methods to ensure the reliability of the measurements.
• to provide adequate and sufficient resources (human resources, equipment, information) for the implementation of quality
operations and use them in a way that ensures the reliability and overall effectiveness of all measures designed and
implemented.
• the quality, impartiality and integrity of the measurements carried out during the quality controls are not to be affected by
any commercial, economic or other pressures.
• all staff involved to be trained and evaluated, so that they know and faithfully implement the task assigned to them.
CONTROL FRAMEWORK
EYDAP has set up the appropriate control framework to ensure that the water available to consumers is safe.
Quality controls concern:
• The raw materials used for water treatment and
• The construction materials of the drinking water distribution network
The chemicals intended for the treatment of water for human consumption and the materials used in the drinking water
distribution networks supplied by EYDAP are specified, in accordance with the international specified standards, such as e.g.
ELOT EN 878, ELOT EN 937, ELOT EN 12201 etc. For each substance and each material there is a quality plan which safeguards
the suitability of its intended use.
• Untreated water, in reservoirs and at the entrance of Water Treatment Plants and
• Drinking water available to consumers
FREQUENCY OF CONTROLS
EYDAP carries out:
• daily quality checks of untreated and drinking water, 7 days a week,
• close monitoring of water quality of four reservoirs, Marathon, Yliki, Mornos and Evinos, with on-site visits, sampling
and analysis at least eight (8) times / year,
• daily sampling and analysis of the quality of drinking water in the water supply network, in order to deal with a
possible problem immediately.
The checks carried out, especially in drinking water, exceed the frequency required by law.
The number of drinking water samples tested for microbiological parameters exceeds 9,000 per year compared to the 3,300
required by law.
WTP - WATER TREATMENT STAGES
Water Treatment Plants (WTP) are absolutely crucial for the water we drink, making it of excellent quality, with a maximum
refining capacity of 1,900,000 m3 of water per day.
The 4 WTPs are located in Galatsi, Acharnes (Menidi), Polydendri (Kiourka) and Mandra in Aspropyrgos.
The surface water reaches WTPs untreated and undergoes 5 stages of treatment (prochlorination, flocculation, sedimentation,
filtering and postchlorination). At the stages of prochlorination and postchlorination disinfection of water is achieved with the
application of chlorine gas. Disinfection procedure permits water to reach consumers free of microorganisms and parasites,
healthy and safe
The WTP Directorate, and consequently the Water Supply General Directorate, initiated the gradual replacement of chlorine gas
with ready- to-use sodium hypochlorite solution at Galatsi WTP.
The use of sodium hypochlorite solution (with a gradual reduction in the use of chlorine gas) was applied first at Galatsi WTP, in
the beginning of May 2021. These days at at Galatsi WTP, sodium hypochlorite solution is the main disinfectant at a rate of 95%.

According to the WTP Directorate’s Plan the complete transition from chlorine gas to sodium hypochlorite solution at Galatsi
WTP will be realized in the 1
st
trimester of 2022.
As for the other WTPs the complete transition from chlorine gas to sodium hypochlorite solution is to be completed in the 1
st
semester of 2023.
More information on the corporate website of EYDAP (www.eydap.gr) in the section "The Company / Water Supply / Water
Treatment Plants".
WATER QUALITY CONTROL LABORATORIES
EYDAP has accredited laboratories in Galatsi and Acharnes for water quality testing. Samples of untreated water from the
reservoir and from EYDAP boreholes and samples of drinking water samples from the Water Treatment Plants and from the
Company's water supply network are analyzed. EYDAP has laboratories for testing the intermediate stages of water treatment,
installed in each of the four Water Treatment Plants.
In EYDAP’s laboratories, the most modern analytical methods are applied for the examination of the data required in water
samples in order to achieve high sensitivity, accuracy and repeatability of measurement. Analytical techniques used include
automatic photometric analysis, ion chromatography, gas chromatography with MS / MS "triple quadrupole" detectors, ECD, FID
and olfactometry, HPLC liquid chromatography with fluorescence detectors with fluorescence and UV detection, plasma
spectroscopes with emission detector, online Daphnia toxicity testing, and ELISA.
In the context of continues progress in quality control mechanisms, in the end of 2021 state-of-the-art analytical equipment
was received, including liquid chromatography system UHPLC-HRMS q-TOF and spectroscopy system ICP-MS, in addition to
equipment specified for the automation and optimization of laboratory works (integrated automatic sample processing system
with Solid Phase Extraction, SPE). Furthermore, the tender procedures for the procurement of automatic thermal circuit (PCR),
equipment for the automation of preparation of nutrient substrates and their distribution in petri dishes, along with the
supportive laboratory equipment for the modernization or replacement of obsolete one were successfully completed recently.
Obsolete equipment included a cooled incubator, laboratory refrigerators, etc
QUALITY PARAMETER MONITORING SYSTEMS
Modern systems for the on-line monitoring of critical quality parameter in raw water are installed at critical points at the
External Water Supply System, permitting the real time monitoring results through telemetry and timely warning in case of
extreme rates.
In 2021, at one of the above stations, a sensor was added for the on-line monitoring of an additional critical parameter, that of
organic load.
In December of 2021, the above stations network timely and successfully located an incident of increased turbidity in raw water
in the Mornos Canal. The stations’ timely notification permitted the adequate process adaptation of EYDAP small refineries. Thus
the risk of burdening the water quality and damaging the processing systems was avoided.
ON-LINE MONITORING OF CRITICAL PARAMETERS AND IN DDRINKING WATER
In selected tanks of the water supply network, residual chlorine is monitored on-line, while in 2021 the procedures for the
supply of modern, continuous chlorine measurement systems have been initiated for all the tanks in operation.
In 2018, two quality parameter monitoring systems were installed in the drinking water network as well.
In 2019 they were enriched with additional sensors and capabilities, in accordance with EYDAP’s requirements.
In 2020 these two systems were further developed with the possibility of returning the sampling water to avoid water losses, as
well as the possibility of energy supply from solar panels and/or hydro turbines. One is installed within the urban area and close
to the Galatsi Water Treatment Plant, while the second is located in the area of Sounio (the extremity of the network). Thus,
EYDAP now has two "smart", energy autonomous and environmentally friendly systems for real-time monitoring of quality

114
parameters in the water supply network, as well as early warning and prevention of potential problems. During 2021, following
the success of the above effort, the procurement of a significant number of such "smart" systems is planned to be installed in
selected points of the water supply network.
Furthermore, during 2021, new on-line equipment was installed at the small refineries of EYDAP SA, located along the Mornos
aqueduct in areas of Boeotia and Phokis prefectures, in order to provide continuous and real-time quality control of the water
produced there. Solutions for the remote monitoring of the quality control of the water quality of the refineries have also been
launched.
PROJECTS AND INITIATIVES
EYDAP systematically monitors and records, in an archive kept by the Water Quality Control Service and in accordance with the
provisions of the Quality Assurance System, not only the current Legislation but also the international trends in regulatory
issues, which may become future Legislative or stakeholder requirements. As a result of this action, the list of monitored
substances is constantly being upgraded.
As part of the continuous improvement of quality testing mechanisms, the following tender procedures are in progress
• 14 advanced systems for the on-line monitoring of critical quality parameters in raw water, that permit the real time
reception of results through telemetry and timely warning in case of extreme rates. The new systems will be installed at
the External Supply System to enrich the existing station nework in positions and parameters
• 53 on-line instruments for the constant monitoring of residual chlorine in drinking water in Drinking Water Tanks , of
EYDAP Water Supply System, in different parts of Athens.
• a new gas chromatography system – sequential mass spectrometry GC-MS/MS, a new ion chromatography of anions, a
new liquid sterilization furnace for the modernization and enrichment of laboratory equipment.
In the context of social responsibility, in summer of 2021, during the multi-day fires in different areas of Athens, for the
continuous safeguarding of the provision of drinking water of excellent quality, EYDAP proceeded to extra tests and extra
analyses and informed the competent authorities on the results.
As an act of social responsibility is considered the support of the Navy, with a systematic provision of laboratory analyses service
of the vessels’ water. Furthermore, EYDAP at times supports the Environmental Inspectorate by contacting analyses.
Out of interest for the environment and at the request, as it resulted from the Technical Environmental Study of 2016 that was
conducted for the identification of the ecological water supply of Mornos Dam, EYDAP completed in 2021 the 3-year monitoring
procedure of the ecosystem downstream the Mornos Dam, which concluded with valid and documented data for the good
status of the ecosystem.
SYNERGIES
For the investigation of specialized water quality issues, EYDAP is in collaboration with Greek Educational Institutions and
Research Institutes (EKPA, NCSR Demokritos) which are among the pioneers in their field in Europe.
In 2020, the collaboration with the National & Kapodistrian University of Athens (EKPA) was completed. The Project aimed at the
investigation of the possibility of the detection of emerging organic pollutants in EYDAP’S reservoirs (Mornos, Evinos,
Marathon, Yliki). A combination of sophisticated “targeted” and non “targeted” analysis techniques was applied, during which
the sample is scanned for the detection and identification of a wide range of unknown substances (over 70,000 compounds),
which until now are not in a detection list, along with the identification of cases of pollutants discharge into the environment,
that were previously impossible to detect.
The results of the collaboration with the University is the first extensive study for the detection of emerging pollutants in the
waters of the reservoirs intended for drinking water. Through this study important documentation data emerged for the good
chemical condition of EYDAP reservoirs, in addition to a list of substances that need to be monitored.
In continuation and aiming at the timely preparation of EYDAP for the development of European and Greek Legislation on the
quality of Water for Human Consumption, in 2021 a new collaboration was approved with the Laboratory of Analytical Chemistry

of EKPA on the same subject (that means specialized analyses), but on samples at the point of inflow and outflow of the 4
Water Treatment Plants (WTPs) of EYDAP, in order to obtain risk assessment data at the specific part of the water supply
system, regarding treatment.
These data will be used in the required by the forthcoming legislation risk assessment study of water supply system, from the
water intake to the water meter and contributes to the optimization of the water quality monitoring program of EYDAP.
The collaboration between EYDAP and NCSR DIMOKRITOS referred to the award of an industrial scholarship to a postdoctoral
researcher, that was completed in 2021. Through this thesis, new methods and techniques were developed that contribute to
the risk assessment of organic pollutants throughout EYDAP’s drinking water cycle, from the reservoirs to the consumer tap.
Recast of Directive 98/83 / EU on the Quality of Water for Human Consumption
EYDAP executives due to their specialization and experience participated institutionally in the consultation that had started in
February 2018 and was completed in 2020 with the issuing of Directive EE 2020/2184.
In continuation of the above project, in accordance to the Decision A1b/C.P.30320/27.07.2021 of Health Minister, EYDAP
executives actively participate to the Working Group of Health Ministry for the harmonization of Directive EE2020/2184 on the
Quality of water for Human Consumption
Outcomes of these policies and non-financial key performance indicators
ACCREDITATIONS
The Chemical Laboratories in Galatsi and Acharnes, as well as the Microbiological Laboratory are accredited according to ELOT
EN ISO 17025 since 2005, by the National Accreditation System (ESYD), for conducting tests to determine chemical and
microbiological parameters in raw and drinking water (Certificate No. 192).
In 2021 for the purpose of maintaining accreditation, two inspections were carried out my ESYD on the Quality System of the
laboratories of the Water Quality Control Dpt (in April reevaluation and scope extension inspection and in December surveillance
inspection).
By the evaluators, the performance of the Water Quality Control Dpt. is extremely satisfactory and reflects the high standard of
its staff. As a result it was granted
• maintenance of accreditation
• extension of the official scope of accreditation with new methods
EYDAP’s water laboratories are now accredited for a total of 75 types of tests / parameters for drinking and surface water, as
well as for sampling.
International developments and trends in the field of water analysis are systematically monitored. The continuous evolution and
improvement of their operation is reflected in the continuous expansion of the scope of laboratories accreditation, ie in the
continuous increase of the number of substances determined using accredited methods.
COMPLAINT MANAGEMENT - CONSUMER INFORMATION
EYDAP gives absolute priority to ensuring a high level of satisfaction for all consumers. It has set up “1022” hotline to record and
immediate address any quality issues that may be reported by consumers. In the majority of cases the response of EYDAP is
within 24 hours at most.
In 2021, 55,3% of complaints were resolved by telephone, while the remaining 44,7% was investigated through sampling and
laboratory analysis. In the same year, technical actions were required in 6,7% of quality complaints reported to 1022 and the
100% of complaints, that demanded EYDAP’s intervention was resolved.

There was no incident of dissatisfaction with a consumer request or an incident of a fine or compensation for water quality
issues.
EYDAP systematically informs consumers regarding water quality in the following ways:
• the average values of all determined parameters are exported on an annual basis. These values are posted on the
Company's website, so that all can access them.
• responds in writing by providing up-to-date information on water quality, to any consumer request. In most of these cases
the answers include reports of results of samples taken from taps inside the properties of the interested parties.
• the water quality data of the EYDAP water supply network are systematically sent to the Ministry of Health. The data for
the three years 2017 - 2019 were sent to the Ministry of Health in early 2020, while the data for 2020-2022 are compiled
and expected to be required by the Ministry in early 2023
PERFORMANCE
As evidenced by the results of approximately 170.000 tests in approximately 10,000 drinking water samples and 2,000
untreated water samples per year, EYDAP constantly certifies that the water of Athens is of excellent quality and one of the
best in Europe.
The results of the analyzes certify that the quality of drinking water of EYDAP meets the legal requirements of JMD C1 (d) / GP
oik.67322 / 2017 "Quality of water for human consumption" in compliance with Directive 98/83 / EC of the Council of European
Union (as amended and in force).
On an annual basis, internal self-evaluation inspections of the various processes of the Water Quality Control Dpt. are carried
out and all functions related to Quality Control are reviewed. In this way, any deviations from the established procedures are
identified and opportunities for improvement are recorded, which are then planned and implemented.
COMPLIANCE WITH REGULATIONS AND VOLUNTARY RULES
During the reporting period, no incidents of non-compliance with regulations and voluntary rules related to the quality
of water supply and with negative effects on the HEALTH and SAFETY OF CONSUMERS were identified.
Drinking water quality control data from the water supply network of EYDAP are available on the Company's website
(www.eydap.gr) in the section Sustainable Development / Responsible Business Practice / Quality of untreated and drinking
water.
D.1.b SEWEARE SERVICES
EAST ATTICA SEWERAGE WORKS
(material issue)
Main non-financial risks
The sustainable development of Attica is closely linked to the responsible and effective management of wastewater. As the
largest company in Greece operating in the water cycle, EYDAP undertakes the collection and treatment of wastewater and
returns treated water that is free of its pollutant load to the environment by applying state-of-the-art international practices.
Our main activity is maintaining a continuous and dynamic presence in this sector by relying on our indisputable know-how and
aiming at the protection of natural resources, the use of modern circular economy methods and the ongoing improvement of
quality living standards for citizens, with an underground network of 8,500 km extending from Agios Stefanos to Salamina and
from Varkiza to Mandra. In 2021, the delivery of the sewage collection network was approved for the towns of Megara and Nea
Peramos, along with the Megara Wastewater Treatment Plant (WWTP).
EYDAP’s operation, especially the disposal and treatment of residential, institutional and industrial wastewater, is based on the
regulatory provisions of Greek and European legislation as well as on corporate initiatives.
Failure to comply with current environmental laws, aside from the potential imposition of administrative or even criminal
penalties, also entails serious risks for public health, soil contamination, and aquifer and surface water pollution. EYDAP closely
monitors the areas where its facilities, particularly the pumping stations, are adjacent to physical receivers so that it can
intervene in good time and prevent incidences of environmental pollution caused by potential overflow.

Risk identification, assessment and mitigation is critical for the Company. Risks are managed with particular care through
specific operational planning and awareness of their economic, social and environmental impacts.
The main risks associated with sewerage issues are:
• environmental degradation in areas that lack sewerage services;
• sewage inflow onto properties or sewage spills into the environment (roads, streams) due to overflows or pipe blockages;
• malfunction of WWTPs due to inflow of wastewater unsuitable for treatment;
• burden on the marine ecosystem, in case of inadequate wastewater treatment;
• impact of climate change (extreme weather events, wildfires, etc.).
Adopting preventive measures, revising action procedures and ongoing modernization of systems aim at ensuring the smooth
and safe operation of the sewerage network and wastewater treatment plants, along with reducing the Company's
environmental footprint by decreasing its energy consumption, supporting the circular economy and minimizing its carbon
footprint.
EYDAP’S RESPONSE TO THE COVID-19 PANDEMIC
Targeted measures, adapted to the requirements for ensuring operational continuity, were adopted to safeguard employee
health and provide uninterrupted sewerage services critical to public health. Special care was taken to disinfect vehicles and
building facilities and to follow all guidelines issued by the State regarding maintaining safe distances and adhering to personal
hygiene measures.
Recognizing its important role in handling these new challenges, EYDAP cooperates with the National and Kapodistrian
University of Athens to carry out specialized wastewater analyses. Analysis results show in real time what is happening in society
(i.e. use of medications, substances, etc.). Recently, these analyses are performed on a daily basis and are an important tool for
predicting the spread of COVID-19.
Corporate policies and due diligence
DESCRIPTION OF SEWERAGE NETWORK
EYDAP is responsible for the construction, operation and maintenance of the sewerage network in its area of competence, as
defined in Article 8 of Law 2744/99, as currently in force.
The served population amounts to approximately 3,965,000 inhabitants. The total length of the sewerage network within our
remit in 2021 was 8,438 km. Our goal is to extend the network to areas that lack sewerage services.
The Attica Basin's sewerage system is organized into stormwater drainage and sewage collection pipelines. According to the
current legal framework, the responsibility for stormwater drainage works and flood protection works, as well as for clearing
storm drains, lies with the Region of Attica and to municipal authorities.
The term "sewerage network" within EYDAP's remit, for which EYDAP is responsible, refers to the sewage pipes, combined
pipes (old mixed network in the centre of Athens), pumping stations, force mains, overflow structures and any construction
designed to collect and transport wastewater to the end receivers.
Pipelines and external sewage branches that have been constructed by third parties become part of the final sewerage
network after delivery to EYDAP.
Sewage pipes usually operate with gravity, but wherever necessary, there are pipes that operate under pressure (force mains).
The Attica Basin sewerage system includes 44 pumping stations, mainly along the coastline of Piraeus, and the coast of
Saronikos and Salamina; 3 new pumping stations at Thriassio Pedio, 1 pumping station at the Municipality of Stamata and 1
pumping station at Adames, while new pumping stations are added continuously from secondary sewerage systems constructed
by municipalities which are later transferred to EYDAP.
Wastewater is transported through the main sewage collectors to the wastewater treatment plants.
SEWERAGE NETWORK CONTROL AND MAINTENANCE
The maintenance of the network and malfunction repair is performed with continuous and immediate intervention by highly
trained personnel using the appropriate equipment that is constantly upgraded.
Pipe damage in the sewerage network occurs due to blockage caused by the disposal of non-disposable materials, i.e. inert
building materials, fats and oils and other objects, or the intrusion of adjacent tree roots.
Almost 80% of the network is digitally displayed, which facilitates the rapid response to any emergent problem.
Proactive and effective problem management is achieved by:
• the use of high-tech Mobile TV Inspection Units (TV Inspection Vehicles) to detect faults;

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
118
• the use of high-pressure tankers and recycled treatment water tankers in case of blockage or for cleaning pipes,
respectively;
• the use of No Dig Technology through TV Inspection Vehicles equipped with robotic machinery for making repairs
without requiring excavation;
• repair/reconstruction of sections of pipes or external branches (connections) to properties;
• maintenance of pumping station electromechanical equipment;
and the extensive use of modern digital systems:
• Digital Emergency Response Vehicle Fleet Management System (e-TRACK);
• Input and processing of data obtained from work performed by repair crews on the Sewerage Portal application. Since
2008, the Sewerage Network Division has maintained a comprehensive historical database (sewerage portal) of failures,
investigations, open cut trenches and other activities which provides invaluable assistance in effectively responding to
network failures, drawing up maintenance schedules, providing faster consumer service and formulating a targeted
investment plan to replace problematic sewage pipelines in the network.
• Pilot application of the on-line updating of the sewerage portal application fault log with field data.
• Two-way interconnection of e-TRACK systems and sewerage portal for direct forwarding of alerts to vehicles in all sectors.
• Input, processing and analysis of spatial network data in GIS environment.
• Compilation and study of statistical analyses based on the aforementioned data and those from the 1022 Call Centre on
the sewerage portal application.
• Monitoring the operation of pumping stations with Remote Control - Telemetry (SCADA) systems. This system monitors,
controls and safeguards the automated operation of pumping stations.
WASTEWATER TREATMENT WITHIN EYDAP'S COMPETENCE AREAS
Wastewater treatment from areas within EYDAP's competence connected to a sewerage network is performed at three
Wastewater Treatment Plants (WWTPs): in Metamorfosi, Attica, (WWTPM), on the island of Psyttalia (WWTPP) and at Thriassio
Pedio (WWTPTP). Primary and secondary processing are defined in European (EEC) Directive 91/271, transposed into Greek law
by Joint Ministerial Decisions 5673/400/1997:
“Primary treatment”: treatment of urban wastewater by a physical and/or chemical process involving settlement of suspended
solids, or other processes in which the BOD5 of the incoming wastewater is reduced by at least 20% before discharge and the
total suspended solids of the incoming wastewater are reduced by at least 50%.
"Secondary treatment”: treatment of urban wastewater by a process generally involving biological treatment with a secondary
settlement or other process in which the requirements specified in the relevant environmental operating permit are respected.
"Tertiary treatment”: advanced treatment to remove nutrient pollution that encumbers receivers (nitrogen and phosphorus),
pathogens, non-biodegradable substances, heavy metals, organic residue and suspended solids and other micro-pollutants.
EYDAP's main concern is to ensure:
• the best, uninterrupted operation of the WWTPs, with ongoing and proper maintenance.
• the continual modernization of facilities.
• the management of treatment by-products using state-of-the-art methods.
• compliance with current environmental conditions.
• compliance with mandated outflow quality limits.
• compliance with the principles of economic circularity and application of sustainable management (production of biogas
and management of generated sludge as alternative fuel).
(The topic is analyzed extensively in the “Circular Economy” section of the same Report).
Psyttalia Wastewater Treatment Plant (WWTPP)
This is one of the largest WWTPs in Europe and worldwide, with a wastewater treatment capacity (average design
discharge) of 1,000,000 m
3
/day.
Currently, the average discharge of incoming wastewater is on the order of 730,000 m
3
/day.
The Psyttalia WWTP treats urban and pre-treated industrial wastewater coming from:
• The broader Attica Basin area (mostly from the capital), except some areas from which the urban wastewater is transferred
to the Metamorfosi WWTP for treatment.
• The island of Salamis.

The biological treatment and drying of generated dewatered sludge takes place at the Psyttalia WWTP.
The facility’s performance as regards the removal of the overall pollution load is as high as 95% or higher for certain
pollutants.
PSYTTALIA WWTP ENVIRONMENTAL FOOTPRINT
The optimized energy efficiency of the Psyttalia WWTP and energy savings was one of EYDAP's most important objectives. For
this reason, operation and maintenance contracts endeavour to ensure that aim is achieved, as it is a key obligation for the
contractor to undertake works and operational adjustments/options to maximize production and use of self-generated energy
sources (biogas) on the one hand, and on the other, to reduce dependence on imported energy sources.
By carrying out works related to the procurement and installation of new equipment and making operational adjustments on
existing and planned new installations and equipment units, a decrease in energy consumption of 23% has been achieved at
the WWTPP since 2014 with an accompanying reduction in greenhouse gas emissions and the carbon footprint.
Sludge processing produces biogas, which is used to generate electrical and thermal energy. Dried sludge that is produced is
used as an alternative fuel by the cement industry. An average of approximately 40,000 tn is produced annually. Improvements
to facilities aim at the overall improvement of operating procedures and achieving the further energy autonomy of the plant by
increasing the amount of biogas generated. Sludge processing and drying is a high-energy consuming and costly undertaking.
(This topic is further examined in the section "Liquid & Solid Waste Management-Circular Economy” of the same Report).
UPGRADES OF PSYTTALIA WWTP FACILITIES
As part of upgrading the plant facilities and the further optimization of its operation to fully comply with the environmental
conditions, the following projects have been designed for implementation within the next five years:
• Construction of a building to temporarily store bins with pre-treatment products at Akrokeramos.
• Equipping and starting up two inactive grit channels.
• Improvement of overflow pipe at Akrokeramos and landscaping of surrounding area.
• Interventions to improve collection and treatment of grease and oils during primary sedimentation.
• Anaerobic treatment of grease and oils with construction of two new digesters.
INFLOW OF NON-TYPICAL URBAN WASTEWATER
As part of addressing cases of incoming urban wastewater with a non-typical composition at the Psyttalia WWTP, a Civil
Engineering professor of international renown at the University of Patras was appointed to conduct a research project on “The
Collection, Processing and Time Series Analysis of Qualitative and Quantitative Parameters at the Entry and Exit of the
Psyttalia WWTP to Identify and Model Emergency Load Incidents”. The project was completed on time in January 2022, with
the submission of the 3
rd
deliverable.
ENVIRONMENTAL CONDITIONS
Wastewater treatment at the Psyttalia WWTP, in regard to the requirements set out in its environmental conditions, has been
consistently successful, as verified by the results publicized every year and posted on the official website of the Hellenic Ministry
of Environment and Energy, as specified by law.
However, there is a deviation in compliance with the condition applying to chlorination of treated effluent (non-compliance with
Ministerial Decision Ειβ221/1965), a fact reflected in the inclusion for the first time as a new condition of the need for
chlorination of treated effluent in the 2009 renewal of the Decision to Approve Environmental Conditions (DAEC) which apply to
the operation of the WWTPP. It is worth noting that there was no provision for construction of a chlorination unit in either the
design, or in the corresponding DAEC, or in the construction of the WWTPP (A&B Phase) by the Greek State.
In this regard, studies by reputable public entities from university and scientific institutions state the following:
A study by the National Technical University of Athens on the chlorination of treated effluent concluded that "it is not
appropriate to chlorinate wastewater at Psyttalia, but it should be avoided". This same study demonstrated, after systematic
monitoring, that the quality of the bathing water (beaches) could be described as being of outstanding quality.
Reports by the Hellenic Centre for Marine Research (HCMR) on the results of monitoring the ecosystems of the interior
Saronic Gulf and Gulf of Elefsina confirm that there is no burden on the marine receiving waters from the operation of the
WWTPs at Psyttalia and Thriassio.
In addition, a study by the National and Kapodistrian University of Athens Department of Chemistry's Analytical Chemistry
Laboratory, relative to the possible addition of chlorine to treated effluent at the WWTPP, concluded that: "The inclusion of the
additional chlorination stage is not recommended as a strategy in the treatment of the effluent from the Psyttalia WWTP,
before its discharge into the aquatic ecosystem".

Fiscal Year 01.01.2021 – 31.12.2021
120
In light of the above, EYDAP has applied to the Ministry of Environment and Energy to remove the condition that pertains to the
requirement to add chlorine to treated effluent from the Psyttalia WWTP DAEC so that what appears to be a regulatory
deviation from the Plant's environmental conditions can be officially eliminated. The benefit to the environment due to the non-
chlorination of treated effluent is already known.
Metamorfosi Wastewater Treatment Plant (WWTPM)
This is the oldest wastewater treatment facility for receiving and co-treating
• urban wastewater through a network of wastewater collectors and
• domestic septic sewage from unconnected dwellings in areas of Attica that lack a sewerage network.
Additionally, pre-treated biodegradable industrial waste is discharged to the Industrial Wastewater Conduit at the Metamorfosi
WWTP, which then ends up at the Psyttalia WWTP for treatment.
The Metamorfosi WWTP has a treatment capacity (average design discharge) of 44,000 m
3
wastewater/day (20,000 m
3
urban
wastewater/day and 24,000 m
3
domestic septic sewage/day). Currently, the average discharge of incoming wastewater is
around 24,000 m
3
/day (12,000 m
3
of urban wastewater/day and 11,000 m
3
domestic septic sewage/day).
At the Metamorfosi WWTP, urban wastewater and domestic septic sewage undergoes co-treatment with chlorination of the
treated effluent and sludge treatment and dewatering.
The rate of pollutant load removal, in terms of organic load, is over 99%.
The final receiver of the WWTP effluent is Pyrna stream.
WWTPM ENVIRONMENTAL FOOTPRINT
Dewatered sludge is transferred to the WWTP for thermal drying (the topic is discussed further in the section "Circular Economy
– Liquid & Solid Waste Management"). The discharge and treatment of domestic septic sewage at the WWTPM helps to
mitigate its uncontrolled disposal into the environment.
The use of generated biogas – a renewable energy source – to heat both the sludge in digestion tanks and the WWTPM
buildings helps to lessen dependence on the use of fossil fuels (e.g. oil), the combustion of which generates carbon dioxide
(CO
2
) emissions harmful to the environment.
The use of biogas as a fuel instead of fossil fuels serves to reduce EYDAP's carbon footprint.
Our goal is to optimize its operation with:
• projects to improve existing treatment facilities and the facilities at the tanker discharge area;
• the implementation of additional deodorization works that are particularly important for the area and for local residents;
• biodegradable industrial waste treatment projects;
• energy recovery projects with produced biogas.
A digital control system (e-pass) was installed in 2018 as part of the control system and to provide faster service for incoming
tankers transporting urban and industrial wastewater to the WWTPM. The vehicles enter the Plant using a prepaid card.
Thriassio Pedio Wastewater Treatment Plant (WWTPT)
The WWTPT has been in operation since 2012 and is the most modern WWTP. It provides an integrated solution to an ongoing
problem for the residents of Thriassio Pedio and helps to restore the balance of the Gulf of Elefsina ecosystem, which has been
characterized as a sensitive receiver.
The Thriassio WWTP serves the areas of Elefsina, Aspropyrgos, Mandra and Magoula, with a processing capacity (average design
discharge) of 21,000 m
3
of wastewater/day. Tertiary treatment is carried out at the Thriassio WWTP.
It achieves a pollution load removal rate of over 95%.
The Thriassio WWTP, a pipeline network of 130 km and 3 pumping stations were built as part of the sewerage works in the area,
in compliance with Council Directive 91/271/EEC concerning urban wastewater treatment.
WWTPT ENVIRONMENTAL FOOTPRINT
The operation of the Thriassio WWTP aims to eliminate septic tanks and the potential discharge of untreated sewage into the
environment. The dewatered sludge generated at the Thriassio WWTP is transferred for thermal drying to the Psyttalia WWTP.
INCREASE IN PROPERTY CONNECTIONS
In an effort to increase the number of property connections, EYDAP

Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
121
• launched a financial incentive program for residents of areas from which sewage would be directed to the Thriassio WWTP.
This program was in effect from mid-2014 until 30/6/2019.
• It bolstered, even with financial incentives, the effort to construct connections to the sewerage network in the
Municipalities of Elefsina, Mandra-Eidyllia and Aspropyrgos (2017 and 2018).
As a result of these actions, in combination with parallel initiatives by local authorities to add connections, there was a
significant increase in the percentage of residents being served, estimated at 91% (second half of 2021).
CONTROL OF LIQUID WASTE DISPOSAL FROM COTTAGE INDUSTRIES & MANUFACTURERS
The special requirements for professional, manufacturing and cottage industries for discharging fluid waste into the
sewerage network within EYDAP's remit are regulated by the Special Regulation for the Operation of the Sewerage
System together with the relevant Joint Ministerial Decisions. EYDAP issues permits to businesses that generate liquid
waste through their production activities so they can legally discharge it into the sewerage network and systematically
samples and tests the network inflow. Samples are analyzed at the accredited corporate laboratories at Akrokeramos
and Metamorfosi.
Penalties are imposed where optimal parameters defined by the Special Regulation for the Operation of the Sewerage
System are exceeded.
EYDAP LABORATORIES FOR CHEMICAL ANALYSIS OF WASTEWATER
Our laboratories are accredited by the Hellenic Accreditation System (ESYD), in accordance with the ISO 17025 standard-
Certificate numbers 862-2 (Akrokeramos laboratory) and 856-3 (Metamorfosi laboratories).
These labs conduct testing on samples of wastewater, sludge and waste originating from:
• the WWTPs;
• the sewerage system pipelines;
• businesses/industries connected to the network;
• tankers transferring septic sewage to the Metamorfosi WWTP;
• properties with sewerage-related malfunctions;
• Environmental Inspectors for issues related to environmental pollution.
In case of businesses/industries, the parameters tested, the acceptable limits and the frequency of sampling are determined by
relevant laws and the respective environmental conditions applying to WWTPs.
STAFF EDUCATION & TRAINING
Sewerage system employees work under particularly difficult and unhealthy conditions (in shafts and pipelines with release of
gases hazardous to health, etc.). They undergo continuous training to ensure they can perform their duties in the best and
safest manner.
Outcomes of these policies and non-financial key performance indicators
Assessment of the effectiveness of the sewerage system's operation and management is based on developing the following
applications and practices, some of which are significant operational innovations:
1. Monitoring of the marine ecosystem of the Saronic Gulf and the Gulf of Elefsina. Evaluation of the results in collaboration
with the Hellenic Centre for Marine Research (HCMR), an independent research organization.
The evolving ecosystems of the interior Saronic Gulf, the Gulf of Elefsina and Keratsini Bay, and how they are impacted by the
Psyttalia and Thriassio WWTPs, are monitored by the HCMR under contract to EYDAP. Monitoring began in 2005 and is ongoing.
Results show a consistent improvement in the ecological status of the interior Saronic Gulf and the Gulf of Elefsina, particularly
at the discharge points of the WWTPs.
2. Publication of wastewater treatment results on the Ministry of Environment, Energy and Climate Change national
database.
Quantitative and qualitative characteristics of the inflow and outflow of wastewater treatment plants are disclosed on the
Special Secretariat for Water database, http://astikalimata.ypeka.gr/. The disclosed data include the following:
• Mean Annual Incoming Flow.
• Mean Annual Incoming Load BOD
5
• Annual Amount of Dewatered Sludge Produced (tn).
• Annual Amount of Dry Solids DS (tn).

Fiscal Year 01.01.2021 – 31.12.2021
122
• Daily values (mg/l) of parameters: BOD
5
, COD, TSS, T-N, NH
4
-N, T-P (at facility entry and exit).
All citizens have free access to the database.
As indicated by the results posted to the Ministry of Environment and Energy database, the quality of outflows at EYDAP's
WWTPs has always been within limits set by their approved environmental conditions for their operation.
3. Progress of Sewerage Projects
To ensure that all areas within its jurisdiction which currently lack access to a sewerage system can obtain access, EYDAP is
cooperating with the municipalities to plan and design the necessary sewerage projects for the Attica Basin. Such works include:
• Construction of sewerage pipelines sporadically in areas within EYDAP's remit.
In progress
• Construction of connections to properties and secondary sewerage network with necessary manholes in remit area in the
north-east and south-east sectors.
In progress
• Reconstruction of force mains in remit area of the south-east sector.
In progress
• Reconstruction of sewerage network, manholes and property connections in remit area of south-west and north-west
sectors.
In the process of signing an agreement.
The tendering procedures for projects are extremely time-consuming, mainly due to continuous law amendments and
litigation. This means that contracts are awarded and signed after a long period of time – more than a year in many cases – from
the publication of the tender documents.
4. Use of IT systems
EYDAP's high specifications for IT systems led the Company to continually upgrade its existing sewerage IT systems and to install
new ones.
5. Monitoring failures in the sewerage network
There were 26,325 network failures in 2017; 25,957 in 2018; while the number dropped to 24,900 in 2019. In 2020, the number
was about the same at 24,982 , with 27,712 failures in 2021.
6. Ongoing modernization of equipment
The following equipment was delivered in 2021:
• 5 vacuum suction and high-pressure water tankers using recycled wastewater
• 7 high-pressure water and vacuum suction tankers
7. Testing of inflows and outflows at WWTPs by continuous sampling and microbiological analysis at EYDAP laboratories
Systematic wastewater sampling, according to needs and current legislation, of inflow and outflow at the WWTPs, as well as at
intermediate treatment stages for chemical and microbiological analysis. The analysis results verify compliance with
environmental conditions established for the WWTPs.
8. Overflows:
Wastewater overflow due to heavy rainfall is permitted by the relevant article (condition d.5 par. 5.2, 5.3) of the Psyttalia
WWTP environmental conditions for its operation. Data on wastewater discharges that arrive at the Psyttalia WWTP for
treatment and based on the capacity of the intake pumping station at Akrokeramos, it is calculated that the discharge that
overflowed in 2021 due to flooding was approximately 2,700,000 m
3
.
9. Wastewater analysis laboratories
In 2021, 6,000 samples were tested at the Akrokeramos laboratory, with 50,000 analyses performed, while the Metamorfosi
laboratory received 5,600 samples and performed 27,500 analyses.
10. Test results of liquid industrial waste after sampling at EYDAP laboratories
Based on test results and given the large number of businesses served (more than 10,000), it was found that businesses are
generally complying with legislative requirements. It is noted that imposed fines (Quality Exceedance Fee) are minimal; 10
companies had been fined up to 2020. Data for 2021 are not yet available.
11. Measurement of inflow at Thriassio WWTP

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
123
Following the actions taken by EYDAP in the Thriassio area, a steady increase in incoming discharge has been noted at the
WWTP. Specifically, based on data from previous years: Average daily discharge in 2015 was 2,100 m
3
/day; in 2016, it was 2,400
m
3
/day; in 2017, it was 4,000 m
3
/day; in 2018, it was 4,500 m
3
/day; in 2019, it was 5,500 m
3
/day; and in 2020, it came to 6,000
m
3
/day.
Of households that could be connected to the sewerage network, 85% have already been connected.
12. For the best management of treatment by-products – Circular Economy,
• a study was completed and an application is ready for implementation for on-site treatment – in a compact unit – of part of
the incoming wastewater at a pumping station of the Central Coastal Collector. The treated effluent will be used for
irrigation at the Elliniko Park;
• the process for characterizing dried sludge produced at the Psyttalia WWTP as an alternative fuel is in progress;
• cogeneration plants generating electrical and thermal energy at the Psyttalia WWTP are fueled by biogas and natural gas.
All of the electricity generated is consumed at the Psyttalia WWTP. Any excess amount is exported to the Hellenic Electricity
Distribution Network Operator (DEDDIE) power grid;
• reuse of treated effluent, which amounted to 300,0000 m
3
at the Metamorfosi WWTP in 2021 and 4,719,279 m
3
at the
Psyttalia WWTP.
13. Social assistance initiatives
• To safeguard the health of citizens, EYDAP intervenes even in areas outside its remit.
• EYDAP intervenes in cases of emergency events to protect the life and health of citizens by providing equipment and
human resources.
• In 2020, EYDAP participated in damage restoration in areas affected by flooding on the island of Evia.
14. Where municipalities are unable to construct secondary sewage pipelines, EYDAP undertakes to build them, as well as to
construct property connections, as part of a program contract signed with each municipality.
In 2020, program contracts were signed:
• with the Municipality of Penteli for the construction of pipelines and connections in the Kallithea area of Penteli;
• with the Municipality of Kifissia for the construction of a secondary sewerage system along some streets of the Municipal
Units of Ekali and Kifissia of the Municipality of Kifissia and the construction of required connections;
• with the Municipality of Oropos, for the construction of the secondary sewerage network and connections in the areas of
Kapandriti, Mikrochori, Polydendri and Afidnes in the Municipality of Oropos.
COMPLIANCE WITH REGULATIONS AND VOLUNTARY CODES
During the reporting period, there were no incidences of non-compliance with regulations and voluntary codes that apply to
the impacts of EYDAP's services on citizen health and safety.
EYDAP'S SEWERAGE PLANNING FOR AREAS OF EAST ATTICA
With a view to protecting the environment, ensuring sustainable development, safeguarding public health and providing a
permanent solution to the issue of urban wastewater disposal in East Attica, EYDAP incorporated the construction of sewerage
projects in the area in its operational objectives.
As the company responsible for providing water and sewerage services in the Attica area, EYDAP SA has taken substantial
action to resolve the problem of non-integrated wastewater treatment, which for years has led to environmental
degradation, the less-than-optimal management of valuable water resources and the imposition of penalties due to non-
compliance with European Council Directive 91/271/EEC.
EYDAP's planning for these important sewerage projects aims at securing the integrated management of the area’s
wastewater and the reuse of treated effluent for maximum environmental benefit.
To that end, the wastewater treatment plants (WWTPs) to be built have been designed to operate with cutting-edge
technology to ensure the reuse of treated effluent, in full compliance with the current institutional framework for reuse.
An Environmental Awareness and Information Centre will operate at the WWTP facilities of the Municipalities of Rafina-Pikermi
and Spata-Artemida and will be used to implement pilot programmes for the best use of recovered water and offer
informational and educational activities focusing on the environment.
Plans for the construction and operation of integrated wastewater management systems in East Attica include works in the

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
124
Municipalities of Rafina-Pikermi, Spata-Artemida, Marathonas, Palini-Paiania, Saronikos, Kropia and Oropos.
In 2021, EYDAP developed a special website katharonero.eydap.gr, in its official corporate websitewww.eydap.gr, for the
continuous information of citizens on the crucial sewerage works in East Attica and the consequent environmental benefits.
A. SEWERAGE PROJECTS IN EAST ATTICA
1. Collection and treatment of urban wastewater of the Municipalities of Rafina-Pikermi and Spata-Artemida and reuse-
discharge of treated effluent
2. Collection and treatment of urban wastewater of the Municipality of Marathonas and reuse-discharge of treated effluent
3. Sewerage system for the settlement of Varnavas-Municipality of Marathonas
4. Construction of sewerage works in the Municipality of Pallini area
5. Construction of a sewerage network in the Glyka Nera area in the Municipality of Paiania
6. Collection and treatment of coastal zone urban effluents of the Municipality of Saronikos and the Municipality of Kropia and
reuse-discharge of treated effluent
7. Sewerage system in the Kitsi area, Municipality of Kropia
8. Sewerage network in the areas of Leontari-Kantza, Kato Balana and Agios Nikolaos-Municipality of Pallini
9. Sewerage network in the southern section of the Municipal Unit of Artemida
10. Sewerage and wastewater treatment for the Municipality of Oropos and discharge of treated effluent for reuse
11. Reuse of treated effluent from the East Attica WWTPs
12. Management, final treatment and utilization/disposal of generated biosolids from East Attica WWTPs
B. ENVIRONMENTAL BENEFITS FROM PROJECT IMPLEMENTATION
Based on plans for the coming years, approximately 300,000 residents of East Attica will be connected to the sewerage
network, while at least 3,500 hectares of arable land in the area will be irrigated with recycled water.
Β1. Water resource protection
For EYDAP, the reuse of treated effluent from the WWTPs is a key strategic choice in the planning and implementation of
projects with a positive impact on aquifer remediation and enrichment and on the conservation of valuable water resources.
B2. Reducing the energy footprint of projects
The significant reduction of greenhouse gas (GHG) emissions in the wider region is seen as an important outcome of project
implementation and operation.
Provision has been made:
• to reduce energy consumption, by implementing new technologies and sophisticated automation systems that enable
precise control and optimal regulation of processes, with a positive effect on related operating costs. The WWTPs have
been designed to allow regulation of standard equipment operation and its continuous monitoring via a modern remote
control (SCADA) system to reduce energy consumption.
▪ The use of renewable energy sources (RES) to cover part of the energy consumption at the Rafina-Pikermi and Spata-
Artemida WWTP.
There is provision for utilising the generated biogas and for installing photovoltaic arrays on the WWTP's free surfaces.
B3. Underground aquifer remediation
According to EYDAP's planning, the Koropi-Paiania WWTP's treated effluent will be reused for the artificial enrichment of the
groundwater aquifer, through either existing wells or boreholes. Studies by EYDAP and other bodies have shown that developing
aquifers in the area around the Koropi-Paiania WWTP have been over-exploited, resulting in a marked, multi-year decline in
water level (phreatic aquifer), salinization phenomena and nitrate contamination. Through the supply-artificial enrichment of
groundwater aquifers and their improved quality, we are protecting the environment and local residents’ quality of life.
The operation of a sewerage system in the East Attica area will also result in a drastic reduction in the use of septic tanks,
mainly absorbent, which creates a significant pollutant load for groundwater.
B4. Upgrading the ecosystem
Implemented sewerage projects contribute to the protection of the local ecosystem and to maintaining the ecological integrity
of NATURA 2000 areas, as well as to their environmental upgrade. The works are expected to improve coastal bathing areas,
while the improvement of the marine environment will also have direct positive impacts on fisheries.

The ability to reuse treated effluent for irrigation will reduce water pumping from the underground aquifer and mitigate
salinization of water bodies.
C. PROJECT IMPLEMENTATION STRATEGY
To ensure the quickest possible operation of sewerage projects in East Attica and to avoid problems and delays resulting from
divided responsibilities during the construction process, EYDAP
• has adopted for the first time a holistic approach to the construction of the individual parts of the projects;
• is undertaking the simultaneous construction of the secondary sewerage network and the corresponding external
branches to connect the properties, the construction of which, based on current legislation, is the responsibility of local
authorities;
• is planning actions, in cooperation with the local authorities involved, to ensure a quicker connection of properties to
the network once projects are completed;
• in cooperation with the Municipalities, is establishing property-owner service centres in the respective areas to provide
information and accept applications along with required documents for the construction of external branches to connect
their properties to the EYDAP sewerage network currently under construction;
• is already operating customer service centres in the Municipalities of Paiania, Rafina-Pikermi and Pallini, and a new centre
is scheduled to begin operating in 2022 at the Municipality of Marathonas to facilitate the process of connecting
properties to the sewerage network.

The completion of the East Attica sewerage works, aside from coming into compliance with Directive 91/271/EEC, will ensure
the sustainability of the valuable water resource, upgrade the marine environment and the aquifer and protect citizen health,
thus contributing to achieving the Sustainable Development Goals as set by the UN.
D.2 ACCESS TO CLEAN WATER, SUPPLY & WATER NETWORK COVERAGE
(material issue)
Main non-financial risks
EYDAP, in order to ensure reasonable levels of water consumption to its customers and meet the obligations of water supply
services, is supplied with the required raw water entirely by the Greek State at the entrance of its Water Treatment Plants
(WTP). The only exception is the Mavrosouvala’s boreholes, which are EYDAP’s property. The Company, manages water as a
valuable natural resource and a vital good for the residents of Attica (and other areas as well).
The Company in 2021 delivered daily, at an average annual rate, 1.081.334, 49 m3 of drinking water to the area of its service,
to certain islands in the South Aegean Region (Cyclades) and the Argosaronic (municipality of Aegina and Agistri), from specific
water meters with the use of water tankers, but also to cruise ships and boats at various ports of Attica etc. In the Water
Treatment Plants raw water is rendered potable with the use of the most environmentally friendly methods with respect to the
natural resources.
Beyond doubt, any malfunction with a negative impact on the quantitative safeguarding of water resources, the transfer and
distribution of water (External Aqueduct System – Drinking Water Supply Network etc) will significantly affect our customers
(lack of water) and the Company itself (damage to its public image, reduction of revenues etc.) in proportion to the problem
extent. By managing the issue with utmost responsibility, the Company contributes to the implementation of Global Goals for
Sustainable Development, as the United Nations has defined this.
According to Law 2744/1999 and the new Contract, with a validity period of 20 years, among the Greek State, EYDAP Fixed
Assets and EYDAP SA, which is valid since 01.01.2021, EYDAP holds the exclusive responsibility of water supply and sewerage
services in its area of competence. A right non-transferable or assignable. The Greek State holds the responsibility, throughout
the duration of the Contract, to provide EYDAP SA with raw water of adequate quantity. This raw water is to correspond to the
characteristics of raw water, to the minimum quantities that are necessary so that EYDAP SA can correspond to the minimum
water supply needs of its customers. The Greek State is also obliged to upgrade the External Water Supply System to safeguard
the provision of the adequate quantity of raw water.
The Company on its part, has the exclusive responsibility – right nontransferable – for processing this water, its distribution as
well as the operation and maintenance of the privately owned water supply network, so that water supply needs of all
consumers in its area of competence, without any discrimination is covered, in terms of quantity and quality.
With a second Contract, with a validity period of 3 years, among the Greek State, EYDAP Fixed Assets and EYDAP SA, valid since
01.01.2021, EYDAP has taken over (for a price) the operation and maintenance of the installations of the External Aqueduct
System.
After the expiry of the above mentioned contract, the maintenance and the operation or the External Aqueduct System is vested
from the Ministry of Infrastructure and Transport to a contractor, nominated through a tender procedure, in compliance with
law 3389/2005 (A’ 232). In this tender procedure EYDAP is not liable to participate, as its founding law does not foresee the
Company’s participation in Interministerial Committee for Public-Private Partnerships (SDIT) outside Attica Prefecture, area of its
jurisdiction.
Based on documented studies of EYDAP services and the opinion of an external legal advisor, the participation of EYDAP in the
relevant tender would be possible by amending the company's founding law. It is noted that the founding law of EYDAP was
made long before the implementation of i Interministerial Committee for Public-Private Partnerships (SDIT)
The amendment of the founding law was not made until the deadline for submission of an expression of interest file on
20/1/2022, despite the relevant actions of the Company, and therefore, EYDAP cannot participate in the A’ phase of the above
tender.
The contracting authority is the Ministry of Infrastructure and Transport and the indicative budget of the project amounts to 235
million euros.

EYDAP will continue to operate and maintain the External Water Supply System (EYS) until the end of its contract, as it has
successfully done for the last 40 years, providing uninterrupted quality and affordable water in Attica, through its
accumulated know-how and experience.
Corporate policies and due diligence
WATER RESOURCES
EYDAP acquires raw water
• Mainly from surface water resources, from the basins of Marathonas, Yliki, Mornos and Evinos that are ranked in A2
category, according to the Directive 75/440/EEC for surface water quality standards intended for the production of drinking
water.
• From these reservoirs, only Yliki is natural (lake) whereas the others are the result of the construction of dams at
adequate spots, on the riverbeds of the Charadros (Marathon dam), Evinos and Mornos rivers.
• From underground water resources, that can be exploited with the operation of approximately 100 boreholes, of an annual
total pumping capacity of 70 - 125 million m
3
of water, depending on the disposal of underground resources and policy use.
Under current operation conditions, the water supply sources of EYDAP is distinguished into:
• Main water sources: Mornos, Evinos.
• Auxiliary water sources: Marathonas (for the supply of Galatsi WTP) and Yliki (in case of emergency).
• Backup water source: underground water resources – boreholes.
PROTECTION OF RESERVOIRS
EYDAP ensures the protection of the reservoirs
• by complying with strict legislation (Healthcare Provision Α5/2280/1983 for the protection of waters, used for water
supply of the capital area, from contamination and pollution),
• by monitoring the works and the activities in the protection zones of the reservoir basins
• by sampling the water quality in the reservoirs
TRANSFER OF WATER – EXTERNAL AQUEDUCT SYSTEM
The transfer of raw water, from the sources to the Water Treatment Plants, is done via aqueducts with a total length of 495
km.
Despite the long distance between the main reservoirs (Mornos, Evinos) and Attica, the biggest amount of water is transferred
via the aqueducts, by the force of gravity, thus avoiding the economic and environmental impact of energy-intensive pumping,
which come into use only in case of emergency, contributing actively to the reduction of our environmental footprint.
Safe transport of raw water
Implementation of four (4) crucial projects in the External Aquatic System firstly for the support-safeguarding of the existing
critical infrastructure of the external aquatic system and by extension its good operation and secondly for the safeguarding of
the alternative use of Lake Yliki for the water supply of Attica. These projects concern:
1. Reconstruction works of Connection Aqueduct F1800 Mornos-Marathon, Kleidi-Dafnoula section
The “Final Study for the Reconstruction Works of Connection Aqueduct Mornos-Marathonas, Kleidi-Dafnoula Section
and Compilation of Auction Documents” M-198, is completed, approved, got final acceptance by EYDAP and delivered
to the Ministry of Infrastructure and Transportation for project implementation
2. Enforcement of raw water transport infrastructure of Kithairon Canal, in the wider area of Kokkini
The “Final Study Enforcement of raw water transport infrastructure of Kithairon Canal, in the wider area of Kokkini”
from K.P. 4+105 until K.P. 5+915 and Complilation of Auction Documents” M-199, is completed and is at the stage of
approval and final acceptance.
3. Completion of Interventions at Thiva Canal of Mornos Aqueduct
The Study will be completed in the first semester of 2022
4. Construction of Supplementary Aqueduct F2000 across sectioned Mornos Aqueduct downstream Kithairona
The Study will be completed in the first semester of 2022
The tender procedures were approved by EYDAP BoD in 2019 for the nomination of contractors for the elaboration of three (3)
studies, which in combination with one study that is realized by EYDAP will contribute to the implementation of the projects.
MANAGEMENT of AQUATIC SYSTEM

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
129
The management methods of the aquatic system by order of importance are:
• the operation of the existing water supply system
• the regulation of the flow downstream the reservoirs
• the water abstraction breakdown per primary, auxiliary or backup source
• water transfer via the external aqueduct system
• additional works for the reinforcement and safety of the water supply system, if needed.
Object of the Management Plan is the study of reasonable, efficient and sustainable ways and methods for the management of
the External Aquatic System (EAS), aiming at the quantitatively reliable, qualitatively and environmentally safe and cost-
effective coverage of drinking water demand in the area of EYDAP’s competence, through the efficient use of the available
water resources for this use.
The management of the water resources system refers to the determination of the extracted quantity from the reservoirs and
the aquifers, its distribution (breakdown) into the network of the external aqueducts, so as to ensure the long-term efficiency
of the resources in the area of EYDAP’s competence, at minimum cost. It also refers to additional projects for the reinforcement
of the water supply system, if required.
The external aqueducts network is actually the entire pipeline system and its additional works (as pumping stations etc.),
extending from the exit of the reservoirs up to the Water Treatment Plants (WTPs).
The external water supply system is depicted below:
The Decision Support System, used operationally on a daily basis by EYDAP for the monitoring and management of the water
supply system, includes the following components (subsystems):
• Geographical Information System, for pictorial representation and monitoring of the water supply system,
• Monitoring System of Water Resources, intended for the supply of Athens,
• Evaluation and Prediction System of Water resources, intended for the supply of Athens,
• Support system for managing water resources, intended for the supply of Athens.
SAFEGUARD OF DRINKING WATER SUPPLY COVERAGE
The safeguard of drinking water supply coverage is realized by all the installations of the water supply network .
The water supply network consists of approximately 14,000 km of main pipelines and distribution network.
The main supply network (primary network) has a length of about 1,300 km and its pipe diameter is bigger than 300 mm, and
up to 2000 mm.
The distribution network has a length of about 12,700 km and consists of the secondary and tertiary network; the secondary
with a total length of approximately 9,000 km and the tertiary 3,700 km approximately. The distribution network consists of
pipelines with a diameter of less than 300 mm, transporting drinking water to consumers.

, 77 pumping stations of total power
33,200 HP, 660 pressure reduction valves from 80mm to 600mm, about 90,000 isolation valves, 104 remote monitoring
points(SCADA), 1475 data recording and remote transmission points (SMS and GPRS) .
In 2021, 25 telemetry instruments for recording and teleporting data (GPRS ) were added in the network, raising the total at
1475 spots.
In the water supply network there about 1000 drinking water quality control points (700 for chloromeasurements and 300
combined for chloromeasurements and other parameters according to legal requirements).
In 2019, about 150 new drinking water quality control points were added to the system. This permitted the enrichment of the
sampling points and also covered the need for quality control of the water supply networks that EYDAP acquired from the
Municipalities of Salamina , Magoula, Agios Dimitrios of Penteli.
All the above facilities ensure the uninterrupted and continuous supply of drinking water and the ability to meet the daily
needs of consumers, taking into account the conditions of seasonal demand.
There are about 2,180,023 water supply connections in full service.
The average daily water consumption for 2021 was 1,081,334.49 m

Further technical, quantitative and qualitative data can be drawn from our website (www.eydap.gr) in the section The
Company/Water Supply.
Outcomes of these policies and non-financial key performance indicators
• The applied method of water resources management are
✓ Scientifically rational
✓ Efficiency: as they utilize water resources to the maximum extent possible
✓ Sustainability: as they do no deplete future water resources in meeting the needs of today
• Demand is met with increased reliability, mitigating the likelihood of non-coverage the demanded quantity of water to
very low and acceptable rate. The concept of liability mainly refers to the reduction of uncertainty caused by the variability
of the natural supply of water resources (drought) , but it concerns other sources of uncertainty, as the adverse
extraordinary events (damage) during restoration projects along the aquatic system for which EYDAP takes care to ensure
the proper operation of the system. In addition, demand for water supply coverage is realized with water of safe quality,
without provoking environmental problems (ecosystem) due to excessive water deprivation. Finally, the demand is
always met in the most economical way.
• EYDAP manages water demand by developing LEAK REDUCTION PROGRAMS (pressure management-water supply zones,
immediate restoration of damages-breakage in the network, supply network repairs and restorations) aiming not only at
customer service, but also to the sustainability of the natural resource.
Aiming to the identification of an economically optimum strategy for the management of leak reduction, EYDAP is in
cooperation with a specialized scientific team from the School of Civil Engineering of the National Technical School of
Athens, after a contract signed on December 8
th
, 2021. The Project focuses on the development of digital tools, adapted
to the needs of the network for the support of the Company on operational basis.
The operational tools to be developed target the optimal replacement prioritization of sections of the network, along with
optimal pressure management, for the mitigation of real water losses in EYDAP SA water supply network.
These innovative applications, as decision support tools, will be compatible with the existing corporate software and
systems and will be connected to the simulation model of primary and secondary network.
For the implementation of these operational tools to the entire network, EYDAP is in preparation of a tender, with the
scope to update the existing central pipeline model and to create simulation mathematical models of the network’s
pressure zones.
Network modeling is of crucial importance, as it permits the simulation of various operational scenarios. Simulation and
direct monitoring and evaluation of results will contribute to network optimization decisions, regarding operational issues
and extension or reinforcement needs.

The Company, with the development of network mathematical models, lays the foundations for future infrastructure, the
Digital Twin Water Supply Network, and its compatibility with other operational tools aiming at real time operation
monitoring and optimization of decision-making.
• Today, EYDAP provides drinking water of excellent quality, at adequate quantity and pressure, to areas where the water
supply system is managed directly by the Company but also to those areas where the local network is managed by the local
authorities.
For those few areas that are not supplied with water by EYDAP but from boreholes, mainly in West Attica, EYDAP has
launched a series of intervention, in cooperation with the Local Authorities, to include them shortly in its network.
To this direction, the project “Water Supply of Kinetta Settlemet, Megara – Phase A’” is underway and it refers the
construction of a new 500mm steel feed pipeline, of approximately 15kms, and a water tank for the supply of Kinetta area.
The Project Contractual Agreement was signed on 1.4.2020, the project is in progress.
In addition, the implementation of the Project “ Perama Water Tank Main Supply Aqueduct from Sxistos Avenue” was
launched. Construction of a new 300-600mm steel feed pipeline, of approximately 4kms that will supply the existing water
tanks of the Municipality of Perama, without the use of boosters that are today in use for the water supply of the area. This
will result to the mitigation of energy consumption to the minimum. The construction contract was signed on 20.9.2021.
The project is in progress.
• The Construction of the undersea main supply aqueduct for the connection of the island of Salamina with the Island of
Aegina, under the responsibility and competence of Attica Prefecture, was completed.
Since January 2022 the island is supplied with EYDAP water.
In 2021 the distribution of reception (in hm3) of water resources for the coverage of total water supply need (EYDAP,
Municipalities, Entities, etc) is as follows.
The above distribution refers to the optimal management of water resources for the specific year.
Extractions measured at water source, with flowmeters.
D.3 RELIABLE NETWORK
Mαin non-financial risks
Top priority For EYDAP is ensuring throughout the water supply system a sufficient amount of high quality drinking water under
conditions of acceptable pressure, while protecting the natural resource.
The design, construction, operation, maintenance and continuous development of the water supply network is a complex
multifactorial process, which requires technical expertise.
The water supply system of an area, through which supply with drinking water is ensured, includes a system of reservoirs,
supply (main) pipes, distribution pipes and water connections.

By "water supply network" we mean all the pipes that carry treated water from the local Water Treatment Plants to the water
meters of the consumers. This is the main part of a Water Company’s facilities, most of which is underground. The water supply
network provides to all consumers pressurized water, suitable for drinking, in compliance to the current standards in Greece,
The extension of the water supply area, the topography, the population density and the estimated change as well as its
geographical distribution, the height of the buildings, the expected consumption with an estimate of the daily average - low and
high - are some of the factors that determine the amount of drinking water supplied, the supply pressure and consequently the
effective design of the network
EYDAP area of Competence is the metropolitan area of the Capital as s defined in its founding law 1068/1980. According to law
2744/1999, EYDAP S.A. was given the opportunity to expand its activities, under conditions, inside and outside the Attica Basin.
Recently with the article 68 of law 4313/17.12.2014 the article 8 of law 2744/1999 waw amended kas as a result the area of its
jurisdiction was extended to all the Municipalities of the Attica Region, as they are defined in subsection i of par. 3 of article 3 of
law 3852/2010 except for the Municipalities of Aegina, Trizinia, Kythera, Agistri, Spetses, Hydra and Poros, of the Regional unit of
islands of the Attica Region.
(Extensive reference in the specific chapter of the same report)
Responsible management of the water supply network and safeguard of water efficiency contributes to meeting the needs and
expectations of our stakeholders and to the increasing of their trust in the Company. In this way EYDAP contributes positively to
Sustainable Development and specifically to the achievement of the Sustainable Development Goals, as defined by the United
Nations, which contribute to the gradual improvement of global resource efficiency in consumption and production and in the
effort to separate economic growth from environmental degradation.
EYDAP RESPONSE TO MANDEMIC COVID 19
EYDAP in compliance to the Authorities guidelines, from the first moment proceeded with all necessary measures for the
protection of its employees and customers, safeguarding at the same time the uninterrupted provision of water supply services.
In this context, the competent General Directorate organized the staff into groups, on a 15-day shift basis, so that if a case arises
provision of service would continue by another group.
Corporate policies and due diligence. Results of these policies and non-financial key performance indicators
MONITORING AND IMPROVEMENT OF WATER SUPPLY OPERATION (demand monitoring, pressure monitoring, pressure zone
modifications, etc.).
Attica is characterized by difficult topography. EYDAP provides water in areas with altitudes ranging from 0 to 600 meters above
sea level. In order to better control the pressure of the pipes, pressure zones were created, that is segmentation of the network
per 30 to 40 meters of altitude difference, operating under specific pressure. The pressure range within the hydraulic zones
ranges from 2 to 12 atm with the vast majority ranging between 4-6 atm. The water supply network is monitored on a 24-hour
basis by a remote control system (SCADA).
Ιn 2021, in the context of network management improvement, EYDAP replaced faulty flow meters with new ones, raising the
total number of flow meters in the main network to 180. 25 telemetry stations were installed in addition to the existing ones,
raining their total number to 1475 and Scada stations to 104.
NETWORK MAINTENANCE - PREVENTIVE AND EMERGENCY (maintenance of pumping stations, valves - fire hydrants, cleaning
of tanks, repairs of leaking pipes – water connections etc.).
Preventive maintenance of pipelines results mainly from the statistical analysis of malfunctions. Similar actions are initiated by
EYDAP for the maintenance of the supply pipes of the water supply network, through specific modern intervention methods. The
same applies and for all the supporting infrastructures of the Water supply network (pumping stations, tanks, wells and large
water pipes, fire-fighting hydrants. ο.κ.).
In addition to the above, the occurring daily failures of the water supply network caused by leaks in the network, are collected by
EYDAP’s call center and Water supply’s portal, and routed for repair to the competent technicians of the Water Supply Sectors.
Repair is implemented immediately, in order to minimize the inconvenience caused to consumers and to restore the smooth
water supply where the network is damaged.
In 2021, the total leaks - broken pipelines and valves, in all networks operated by EYDAP, amounted to about 6,750.. These
leaks were repaired in their entirety directly by the Services of the General Directorate of Water Supply.
REPLACEMENT AND REHABILITATION OF EXISTING NETWORK PIPELINES AND WATER CONNECTIONS IN PROPERTIES
EYDAP’s existing network consists of pipes of different cross sections and different materials, which have been installed over the
years to serve the increased water needs of the residents of Attica.
Many of these pipelines have been in operation for a number of years. Due to the initial installation conditions, the development

Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
133
of the city, the successive works on the streets and other public spaces, in combination with other factors (traffic, other external
factors), pipelines have undergone significant stress leading to frequent breakage. The same applies for water connections,
served by these pipelines, are equally aged and show similar stresses. The operating conditions of these pipelines are evaluated
by EYDAP, so that pipeline and water connections replacement projects of the most modern material, is put forwards.
In 2021, EYDAP planned and replaced
• a total of 112,600 km of pipes of various cross sections.
• approximately 13,700 water supplies in properties.
“SMART METERS”
Until the end of 2021, EYDAP replaced 1,085 old water connections, cross-sections ranging from 2 inches to 6 inches, with
corresponding electronic water connections of modern technology “smart meters” with an equal number of dataloggers.
The “smart grid”
• Includes information and communication technology in distribution infrastructure and in the whole range of its
operation.” Smart meters” advantage is advanced data calculation, communication in the most modern technology and
transmission of information for monitoring, prevention and resource saving and rightful charges.
• Contributes το water saving projects (leak reduction, optimization and automation in the management of water
resources).
• Is able to satisfy a future increase in demand, reinforce the operational efficiency of the network and to incorporate
“smart” customer devices for service improvement and interaction with customer.
• Regulates and monitors water supply, targeting to “smart “interconnection with customers
• Contributes to the safeguarding of more economical and safer network, with reduced leaks, providing service in due
time.
EYDAP can now
• Collect analytical data for the state of each special water connection via tele-programmed rate of data collection and
transition to central infrastructure (Operational Business Centre)
• To provide information to special customers on consumption and water connections in an analytical and
diagrammatical form
EYDAP introduced in its Strategic Plan the installation of smart meters for household use, in replacement of the old technology
ones in the transition stage to smart water network and modern technology. In this context, in 2017-2018 two pilot application
were put in action with the installation of 80,000 electronic household meters in the Municipalities of Chalandrii and P. Faliro.
In 2021, the Company installed 370 electronic water connection at Varvakeio Market and the nearby streets to make meter
reading easier and consistent, considering the special conditions of the area.
NEW CONNECTIONS
EYDAP continues to install new common water supplies and Special Connections on properties, upon request and in
compliance with the provisions of Water Supply Networks Regulations.
The water supply connections adhered to the water supply pipelines are divided into:
Water supply, fire-fighting, buildings’ common use areas, irrigation of public or municipal areas, for temporary use-r construction
sites or other use.
In 2021 EYDAP installed approximately
7,000 household connections
1,500 more than last year special and fire-fighting connections, a number that indicates the intense construction activity in
the city.
FIREFIGHTING HOSES
EYDAP in 2021, having as a priority the prevention of fires and the readiness for the protection of life, health and environment in
collaboration with the Fire Service, checked the proper operation of all installed Fire Hoses. The inspections revealed the

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
134
necessity to repair 19 Hoses, the replacement of 47 faulty ones and the installation of another 14 new one under the
instructions of the Fire Service in various spots in the network.
WATER TANKS
For the safeguarding of the high quality of water delivered to consumers, EYDAP every 3 years proceeds to the periodical
cleaning of the water reservoir tanks. According to this plan, in 2021 16 water tanks of the network were cleaned.
INCORPORATION OF NEW NETWORKS
EYDAP incorporates Water Supply Networks within its area of competence, managed by the relevant local municipality. The
incorporation of these Networks, mainly in Eastern and Western Attica, is a strategic goal of EYDAP.
The incorporation of the Municipal Water Supply Networks by EYDAP does not take place unilaterally. Basic precondition is the
approval of the Municipal Council of the Municipality.
In 2021 EYDAP :
• incorporated the water supply network, constructed by the Labour Employment Office (ΟΑED), of the Municipality of
Elefsinα. The network will serve Workers’ Housing.
• Signed the contract with the Municipality of Megara
✓ for the transfer and delivery to EYDAP of the local sewerage and water supply network and of the waste water
treatment plant, of the local sewerage network of the city of Megara,
✓ the local sewerage network of Nea Peramos,
✓ the local water supply network of Kineta, Vlyhada (AgioisPanteleemonas), Nea Zoe, Kandili, Koumindti, Lakka, Agia
Triada, Eremou Koima, Pahi
✓ the recognition of the Municipality’s Debts
In 2021, the consultations for the receipt of
• the water supply network of the Municipality of Paiania.
• the remaining part of the water supply network of Vari - Voula - Vouliagmeni Municipality
• the water supply network of "POLITIA" the MPs' Building Cooperative.
are in progress.
At the same time:
• The BoD approved the public tender procedure regarding the extension works, the improvement and replacement of
popes and water connections and other installations of the network at Salamina Island. The tender procedure is in
progress
Under certain conditions, EYDAP may undertake the supply and management of networks in areas outside its competence.
In 2009 the new Water Supply Network Regulation of Operation was approved, which regulates in detail the most important
issues of operation of the Company. The consumer directly adheres to this regulation by signing the water supply contract with
EYDAP.
The Company has included in its strategic actions for the optimal management of its network, the following:
• The application of advanced pressure management technologies in the water supply network, which results in the
avoidance of unnecessary stress on the network pipes from excessive pressures and consequently the avoidance of
network breakage, thus achieving a long life extension with significant financial benefit.
• the reliable and organized collection of data from defaults, operation, etc. so that through structured and
interconnected applications the further processing and statistical utilization of the collected data is achieved.
• Location of the frequency of faults, the speed and quality of repairs, the geographical dispersion, the cause of
occurrence, etc. in order to compile a complete and systematic maintenance program of the water supply network.
• the inclusion, in the five-year investment program of the Company, of a targeted, with documented priority
program of replacement of water supply network, which includes the replacement of approximately 150 km of pipes
(primary-secondary and tertiary network), which corresponds to approximately 1.5% of the total length of the network
per year, following and adhering to global best practices.

With the above, in combination with the other actions and interventions that have already been launched (mass replacements of
water meters, interventions in ducts, maintenance and renovation of existing infrastructure such as pumping stations, wells and
valves, routing through network interventions existing operating structures), it is estimated that more efficient operation of the
water supply network will be achieved, consistent reliable and uninterrupted water supply, improvement of the level of service
to consumers and ultimately improvement of the overall corporate image regarding the performance of its services.
EYDAP's goal in the Water Supply Sector is the constant and targeted transition to new technologies by monitoring and
utilizing all the modern trends of the technologically advanced international water market.
In this regard, a number of EYDAP executives monitor the activities of international water organizations, and international
exhibitions related to water, visit large factories producing materials and instruments and are in constant consultation with
other advanced water companies and international practices, which have incorporated or have begun to integrate new
technologies in order to move to the smart water network.
SYNERGIES - Digital Innovation Competition
An important action in this direction is the Digital Innovation Competition, an original, open competition for technological
innovation, announced in November 2020 in collaboration with the Innovation Network of EESYP and the MIT Enterprise Forum
Greece.
Start-ups, groups of scientists, research centers of universities, etc. were invited to offer innovative solutions to two challenges:
(the subject is analyzed in chapter “Digital Transformation” of the same Report)
D.4 BUILDING/STRENGTHENING A SOLID RELATIONSHIP OF TRUST WITH CUSTOMERS AND END USERS
(material issue)
Main non-financial risks
Understanding customer needs, analyzing data and continuously adapting our processes are key factors in building a solid
relationship of trust that ensures continuity and growth.
The Company's customer-centric orientation has as its ultimate goal the continuous adaptation to the modern concerns of
consumers through a more efficient operating model while always maintaining the provision of high quality services.
In addition to all of the above and in order to address any risks that may arise with regard to the servicing of our customers, the
General Directorate of Customers ensures that measures and safeguards are taken to avert the loss of customer communication
with our company. We apply methods that ensure the optimization of the customer experience by adhering to time and quality
indicators, based on the customer commitment charter.

EYDAP’s response to the COVID-19 pandemic
During the pandemic period, the company, with an absolute sense of responsibility, created a sanitary environment for both its
employees and its customers, fully implementing the sanitary protocols and adopting additional protective measures based on
the needs and processes of its individual departments.
In 2021, new digital tools were also adopted to ensure both service and the health of customers and employees. Where this was
not feasible, customer visits to the Regional Centers were made by appointment.
Modern water supply and sewerage services
EYDAP with the responsibility of supplying water to more than 40% of the Greek territory, is conscious of its responsibility to
provide drinking water of excellent quality and uninterrupted collection of wastewater, while returning it to the environment
95% clean. All our actions are oriented to the protection of the natural resource and marine environment.

footprint, as a process of adaptation to climate change, using modern technological applications.
Through initiatives and actions we encourage our customers to save the natural resource, water. By serving our customers
remotely we reduce the required trips of citizens resulting in reduced emissions of pollutants, reduced consumption of paper
and consumables. In addition, we are constantly upgrading our facilities in order to save energy inside the buildings, to fulfill the
objectives of environmental responsibility towards the community.

• The comparison between the delivered and desired customer experience.
• The setting of monitoring indicators
• The strengthening of Technical Support

present but also in perpetuity, with clearly defined procedures and methodology.
Of the total number of water connections (2,226,996) , 1,611,272 are identified (72.35% ).
Our objective is to identify all water connections.

D.5 AFFORDABLE TARIFF AND SECURE CUSTOMER SERVICE
(material issue)
Main non-financial risks
For EYDAP, continuing to provide high quality water supply and sanitation services at an affordable price for consumers,

CONSUMER DATA PROTECTION
EYDAP, as a Data Controller, places particular emphasis on the protection of its customers' personal data both during collection
- and this applies to all analogue or digital sources - and during processing and maintenance. It takes particular care to
implement the technical and organizational measures provided for by the current legislative framework and invests in the
appropriate training of its human resources by area of specialization.
In order to inform consumers on Personal Data Protection issues, EYDAP updates and publishes the Consumer Privacy Policy,
through the bill (printed or electronic form), the official corporate website www.eydap.gr, the digital applications and directly
when a request is made. In cases of use of digital applications of EYDAP or the digital services provided through its website,
further specific information is provided to the user through simple and clear terms of use and specific updates - Privacy Policies
regarding the processing of his/her data. All personal data processed by EYDAP have been brought to its knowledge by the
Subject or a person authorized by the Subject or are obtained from publicly published data or Public Authorities to which the
Company has legal access and limited to the service of the water supply contract and consumer information.
Where appropriate and in the context of serving the Company's legal obligations, data may be disclosed to public authorities
(e.g. the Hellenic Revenue Authority, judicial or investigative authorities), which process data as third party and independent
Data Controllers for a specific and sole purpose, as defined by the legal framework.
In case of the necessity to issue statistical data, as in this case the relevant need was created in the year 2021 in the context of
the Project "Designing a Strategy for the Sustainable Development of the Company" and for the general optimization of the
services provided by the Company, the competent Services of the Company take care of procedures for the anonymization of
personal data, ensuring the prior notification of the Subjects.
EYDAP evaluates, examines and responds to and, where appropriate, satisfies any query submitted to it with a particular sense
of responsibility and respect towards the consumer, adhering to the relevant Policies and Procedures that it applies in principle
within the legal timeframes set by the regulatory framework.
In the reporting period, there were no findings of violations of the legal framework regarding the management of company's
consumers’ personal data.
PRICING POLICY
EYDAP, committed to its values of access to clean and cheap water for all and reliable sanitation services, but also fully aligned
with the current conditions created by the pandemic for both households and businesses, applies a pricing policy that provides a
flexible and affordable tariff based on the needs of the customer.
In 2021, our customer service refers to 2,226,996 connections. The increase over 2021 was 0.39% and the increase in 2021 over
2020 was 0.33%.
2,188,366 connections are for domestic use, an increase from 2020: 0.29%.
The number of common/professional/industrial connections served is: 2.192.207
2,059,230 connections are for Water and Sewerage, increase rate from 2020: 0.37%.
123,030 connections relate to Water Supply, increase from 2020: 0.49%
44,736 connections relate to Sewerage, increase from 2020: 0.57%.
The Company's water supply and sanitation tariff is determined on the basis of Government Gazette 3188B/16.12.2013 and is
available on the Company's website (www.eydap.gr) in the "Customer Service / Tariff" section.

The tiered tariff acts as a deterrent to the waste of the natural resource and indirectly contributes to the reduction of the
environmental footprint.
The average monthly water bill is 11.44 €/month (Adjusted Price for normal consumption 10 m3 = 3.53 CcF)
The average annual price per m3 of water consumption is: 0.76 €/m3. The price refers to total revenue from water supply and
sewerage services to total consumption: 309.278(χ thousand.€)/406.782 (thousand m3)=0,76€/m3
The adoption of the above policies has a twofold objective as these management and control strategies, on the one hand,
respond to a large extent to the actual needs of households and businesses, and on the other hand, help and raise awareness
among consumers to adopt a rational use of the natural resource.
The existence of affordable tariffs ensures that social inequalities are mitigated and protects vulnerable social groups from being
deprived of water, a basic social good.
On 22.05.2017 the National Water Commission issued the 135275 Joint Ministerial Decision (Government Gazette
1751B/22.05.2017) on the "Approval of General Rules for Costing and Pricing of Water Services. Method and procedures for the
recovery of costs of water services in its various uses". The above Joint Ministerial Decision sets out the procedures, methods
and levels of cost recovery of water services, in order to boost the economy, as well as the general rules for costing and pricing
of water services, in order to ensure the provision of affordable water of appropriate quality and quantity to consumers.
According to the above-mentioned GG, for the determination of tariffs to end-users, in addition to the environmental cost, the
resource cost is included and the environmental charge will be compulsorily indicated in a distinct, clear and understandable
manner.
SPECIAL TARIFFS
EYDAP under a legislative provision (Government Gazette 552B/26.3.2009, article 3.2.3, Government Gazette
3188B'/16.12.2013, Government Gazette 2221B'/9.9.2013) grants tariffs for special categories of consumers, in recognition of

CUSTOMER DEBTS
Despite the general economic crisis affecting households, customers’ debts, with the systematic and persistent effort of the
Services, are kept at approximately the same levels as the previous year. EYDAP, putting its social sensitivity into practice,
applies a discount policy, takes preventive measures to avoid debt ballooning and applies debt repayment facilities through
procedures approved by the Board of Directors.
In 2021, the Company's main actions to minimize, as much as possible, the debts are as follows:
• Timely customer notification of increased consumption by sending an email to identified customers, and also by pasting a
special notification at the entrance of the property.
• Informing letters concerning debt issues. There were 66,989 such letters sent in the year 2021, compared to a total of
261,207 in the year 2020.
• In 2021, 54,129 electronic notices (37,548 sms/16,581 emails) were sent regarding an impending water supply interruption
due to debt.
• Settlement of debts based on specific and established procedures after submitting a request either at the Regional Centers
or by using our new online services.
• In 2021 the number of debt settlement requests made was 16,812.
• Interruption of water supply to the property due to overdue debts/ Removal of the water meter/ application of the KEDE,
if the conditions are met and always in accordance with the Regulation on the Operation of the Water Supply Network

➢ Using a debit, credit or prepaid card of the respective partner banks and redirecting to the payment system
environment of DIAS SA.
➢ Through web banking.
• Partial payment on the website easily and quickly.
Interruption of sending bills
Inn 2021, for a period of approximately 5 months (from 24/4/2021 to 22/7/2021 and from 16/9/2021 to 14/11/2021), the
dispatch of water and sewerage bills to consumers was interrupted as a result of the long-lasting legal dispute between the
candidate postal service providers, during the tender procedure for the award of postal services by EYDAP and in application of
Law 4412/2016 "Public Contracts for Works, Supplies and Services".
The result of this externality was the delayed delivery of bills, due to the inability of EYDAP, due to the legal framework, to assign
this service to one of the providers.
This inability was overcome by a legislative regulation and on the 15 of November the distribution of bills to consumers started
without further delays. During this period and for the cases of consumers affected by this delay, the Company did not interrupt
the water supply and ensured that no surcharges were imposed.
Throughout this period, consumers have been able to receive an ebill via email or sms, by registering on its eEYDAP online store,
through www.eydap.gr .
SUPPORTING SOCIETY
EYDAP is undertaking important initiatives within the framework of its pricing policy to support vulnerable social groups,
recognizing the unfavorable economic situation experienced by Greek society, as well as the crisis caused by the Covid-19
pandemic.
Special debt arrangements are in place for consumers belonging to the weaker social groups (COT and EET beneficiaries).

In the framework of the smooth operation of the Company and its contractual and legal obligations, and in particular in the
framework of social security or labour law, the employees themselves constitute a basic category of data subjects. EYDAP
considers its human resources as the basic pillar of its operation and constantly takes measures to protect their personal data
across the entire range of its activities, even in critical situations, such as that of the global health crisis, demonstrating absolute
respect towards the individual freedoms and rights of employees.
Via its Employee Personal Data Protection Policy, EYDAP informs its employees about the processing of their personal data by
the Company and, as the case may be, they are called on to individually sign forms/statements to ensure that they are informed.
This information is updated according to Company activities and also includes specific information on individual processing,
based on policies such as the Insured Parties Policy of the Healthcare Directorate and the Whistleblowing Policy.
The personal data of our human resources are protected through:
• technical and organizational security measures on our premises and in the systems used to keep the data;
• the establishment of Limited Access Policies, Information System Security Policies and Confidentiality Clauses;
Staff is facilitated in the exercise of their relevant rights through the establishment of simple and clear procedures for the
exercise of rights, processing, evaluation and satisfaction of requests. This procedure is regularly filtered and re-evaluated by the
Data Protection Officer.
There were no breaches of personal data rights regarding employees in 2021.
THE RIGHT TO TRADE UNIONISM
The constitutional right of being a member of a trade union is exercised by the EYDAP Employees' Union, which is a Secondary
Trade Union founded in 1979 and represents the Company's employees.
The aim of the EYDAP Employees' Union is to study, protect and promote the trade unionist, financial, professional, moral,
insurance and social interests of its members, to protect the environment, to implement the principle of gender equality and to
ensure corporate responsibility.
The objective is to pursue the improvement of employee working conditions through dialogue and cooperation with EYDAP's
management, always within the framework of corporate social responsibility rules.
In order to achieve its objectives, the Union negotiates with each competent body or person so as to resolve the problems of its
members and act for the drafting of Business Collective Bargaining Agreements. Furthermore, the Union actively participates in
the meetings of the Administrative and Disciplinary Boards and other entities. Finally, the Union has a presence on the Board of
Directors of EYDAP with 2 members, who have the right to vote.
BENEFITS FOR EMPLOYEES UNDER OPEN-ENDED CONTRACTS
The Company, in the context of peace and stability at work, has, in addition to the legal benefits it provides its employees, also
established benefits such as:
• Health Service, which provides primary health care services to employees and their insured family members and manages
their medical and pharmaceutical coverage
• Private insurance for employees and their children
• Pension insurance for doctors, engineers and lawyers (upon request)
• Ownership of shares
• Provision of expenses for children's camps, for undergraduate or postgraduate studies of employees, etc.
PROTECTION OF THE FAMILY
In 2021 and in the framework of family protection, but also in implementation of Law 4342/23-12-2015, 18 Company employees
(10 Men and 8 Women) were granted 9-month parental leave, instead of the reduced hours provided by law. 100% of
employees who were granted leave which expired in 2021, returned to work after it expired.
At the initiative of EYDAP
• employees are provided with eight (8) days of leave per year, instead of the five (5) days prescribed by law, due to a child's
illness, aged up to 16 years and not up to 12 years as again defined by law.
• working mothers are given the opportunity, after exhausting the maternity leave provided by law, to receive parental leave
with half salary until the child turns two (2);
• 4 days of leave are granted to every parent for each of their children so that the working parents may be informed about
their children’s progress at school; this benefit concerns children aged 5-18 years.

WOMEN IN EYDAP
In 2021, out of the total number of employees under open-ended contracts:
✓ 30,7% are women
✓ Out of the 259 employees holding positions of responsibility, 141 are women
✓ Out of the 2067 employees not holding positions of responsibility, 714 are women
Out of the 13 members of the Board of Directors, 2 are women (15.38%), one of whom is the Chairwoman of the Board of
Directors.
PEOPLE WITH SPECIAL NEEDS, LARGE FAMILIES, CHILDREN OF WAR INVALIDS, ETC.
Pursuant to the provisions of law 1648/1986 (law 2643/98) concerning people with special needs, large families, children of
war invalids, etc. EYDAP has included in its human resources 213 individuals, to whom every facility and protection has been
provided in accordance with current legislation so that they can work safely and efficiently.
The Company has never had an issue of unequal treatment and discrimination against an employee due to gender, age,
religion, sexual orientation, disability, etc.
D.6.b HEALTH & SAFETY OF EMPLOYEES
(material issue)
Main non-financial risks
For EYDAP, protecting its employees’ mental and physical health is part of its business ethic and integrally linked to its business
continuity and growth. In the belief that strong protections in the workplace contribute positively to performance and good
labour relations, Occupational Health and Safety is seen as an important obligation our Company has to both employees and to
their families.
The main risks the Company must address in regard to employee safety, as part of providing uninterrupted water and sewerage
services to the Greek capital, relate to the variety and particularities of the workplaces (administrative services, off-site work
crews, work sites, refineries, wastewater handling, etc.), the use of machinery and tools, the ergonomics of the workplace, and
unforeseen situations (e.g. extreme weather conditions, the COVID-19 pandemic).
Having developed a framework of environmental, social and corporate governance (ESG) principles, the Company can
comprehend and address inherent ESG risks, and commit to protecting the health and safety of its employees. Safeguards
against ESG risks minimise potential adverse impacts (financial, reputation, etc.) and work to ensure its economic prosperity in
the long term.
The importance of coordinated preventive and preparedness efforts as a factor in social cohesion became even more apparent
while managing the COVID-19 pandemic.
Corporate policies and due diligence
EYDAP recognises that safeguarding worker health and safety and preventing risk is not only a legal but also a moral
obligation.
EYDAP’S RESPONSE TO THE COVID-19 PANDEMIC
In the wake of the World Health Organization (WHO) classifying the epidemic of the new coronavirus SARS-CoV-2 as a pandemic
on 11 March 2020, EYDAP responded to the threat with awareness of the particularities of each business unit and coordinated
business plans and organizational measures to ensure its continued operation and safeguard the health of its employees and
customers.
With a strong sense of responsibility, EYDAP steadfastly complied with all special health protocols issued by the Greek National
Public Health Organization (EODY) and the regulatory provisions (legislative acts, circulars, etc.) issued by the Greek government.
The Company established a Special Crisis Management Team and compiled a Business Action Plan.
In 2021, EYDAP reinforced its policy against the COVID-19 threat and received a COVID SHIELD EXCELLENCE Certificate on
14/6/2021 from the accredited certification body, TUV AUSTRIA, for swiftly adopting the necessary measures to prevent
transmission and spread of the disease.
The certification applies to the essential measures in place, based on the current health protocol, at the regional plant facilities
throughout Attica, at the administrative and personnel buildings in Perissos and the buildings at Athinas and Laodikias streets,
and includes an assessment of the Company’s performance on a weekly basis. It also covers reviews of the effectiveness of

Fiscal Year 01.01.2021 – 31.12.2021
146
adopted measures, compliance with the certifying body’s comments for improvements and, as already mentioned, monitoring
and rigorous adoption of guidelines under current law. The certificate is valid for 1 year, and provides for 5 supervisory visits
within that year.
Employee awareness of the value of complying with the adopted measures went a long way to increasing their effectiveness.
Thanks to ongoing information and reminders by the Internal Protection & Prevention Department, compliance was significant in
2021.

“COVID SHIELD” CERTIFICATION MONITORING-IMPROVEMENT
1. Starting in November 2020 and every 4 months thereafter, a self-assessment check list is distributed to Company
departments with regard to measures to prevent the spread of the coronavirus SARS-CoV-2.
2. The form is filled out by those responsible for the Labour Inspectorate Book at each facility and is forwarded to
Management for review and assessment of responses. The form includes:
General information
Organisational measures
Personal hygiene measures and PPE
Environmental measures
Special measures to prevent spread and monitoring employee health in relation to the coronavirus SARS-CoV-2.
3. At the end of each week, Management is briefed, through the Division for Health, Safety, Environment and Quality, on the
number of cases at the Company, where the cases occurred, and a visual representation of the data in graph form. In this
way, Management can assess the results of implementing all the measures and plan next steps.
4. Compliance is verified through members of the IPPD, particularly Safety Technicians and Occupational Health Physicians.
5. At the end of the year, Management conducts an annual review to assess our performance, whereby all of the findings
from internal inspections that have been conducted are collected for assessment and the effectiveness of applied measures
is reviewed, along with compliance with the certification body’s recommended improvements and monitoring and rigorous
adoption of current legislative guidelines.
INTERNAL PROTECTION & PREVENTION DEPARTMENT (IPPD)
WORKER HEALTH & SAFETY COMMITTEE (WHSC)
As part of implementing applicable legislation, EYDAP has established the Internal Protection & Prevention Department (IPPD),
which serves as an advisor to Management on health and safety issues. As per the same law, a Worker Health & Safety
Committee (WHSC) has been formed as an advisory body and consists of elected worker representatives assigned to highlight
occupational risks. In case of a serious work-related accident, the Committee proposes measures to prevent a recurrence and, if
there is immediate and serious risk, it asks Management to take the necessary measures and even to stop the operation of the
machine, installation or production process.
Quarterly meetings are held with Management, WHSC and IPPD representatives, and are attended by the Occupational Health
Physician and the Safety Technician.
EYDAP’s Health & Safety Policy, posted on the corporate website www.eydap.gr, applies to all employees regardless of their
type of work contract (open-ended contract, waterworks service workers, part-time cleaning contract workers, 8-month contract
workers, 8- and 2-month student interns, trainee lawyers, Vocational School students).
The Internal Protection & Prevention Department (IPPD):
▪ Complies with legal requirements, standards and internal guidelines.
▪ Communicates openly and transparently with all interested parties.
▪ Ensures the strengthening of a health and safety culture at the workplace.
▪ Drafts Written Occupational Risk Assessments for every task performed.

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
148
▪ Takes measurements of harmful substances in work areas.
▪ Drafts specifications for personal protective equipment and collective protective measures.
▪ Records and investigates occupational accidents.
▪ Drafts an annual activity report with observations by Safety Technicians by activity, as well as IPPD recommendations for
improving procedures.
▪ Prepares a program for Occupational Health Physicians to issue Fit for Work Statements.
▪ Prepares a schedule to vaccinate employees.
The Company's Health & Safety Policy applies to all EYDAP employees regardless of their type of work contract (open-ended
contract, waterworks service workers, part-time cleaning contract workers, 8-month contract workers, 6- and 2-month
student interns, trainee lawyers, Vocational School students). Contracted personnel working in EYDAP's area of responsibility
are not included in EYDAP's obligations. Contractors are required to comply with occupational health and safety laws and to
have their own Safety Technicians and Occupational Health Physicians.
The data described in this report refer to the categories of employees mentioned above.
CERTIFICATIONS
Since 2020 and during 2021, the IPPD was certified to the ISO 9001:2015 standard for the Quality Management System and to
the ISO 45001:2018 standard for Occupational Health and Safety. These are two internationally recognized standards for
managing the quality of the services the Company offers in the area of Occupational Health and Safety. Reassessment was
pending as of March 2022.
WRITTEN OCCUPATIONAL RISK ASSESSMENTS (WORA) – DIGITAL UPGRADE
The revision of Written Occupational Risk Assessments (WORA) began in 2020 to include new data related to COVID-19. The
revision was completed in 2021 with its harmonization with the Company's new organizational chart. WORAs are updated each
time a change in work method is noted by the Safety Technicians or pointed out by employees. Any employee suggestion is
taken seriously; it is recorded and considered for adoption.
In 2022, a consultation process will be undertaken by the competent organizational units to adopt employee suggestions related
to WORAs.
In 2021, 250 revisions were made to WORAs, out of a total of 300 WORAs.
The WORA is a key requirement of the law (Article 43 of Law 3850/2010) and of the international health & safety standards for
prevention of incidents (occupational injuries and/or illness) which are the result of employee exposure to hazards in the
workplace and the activities carried out there. Since 2020, new, upgraded software is used to make WORA revisions. The
software is an easy-to-use and effective tool for reviewing and revising WORAs so they can remain effective and up-to-date, and
has the capability to access older versions of the document.
INSPECTION SCHEDULE
As every year when preparing the annual programs for Safety Technicians & Occupational Health Physicians, the inspection
schedule was submitted to the Labour Inspectorate (SEPE) at the start of 2021.
The main purpose of these inspections is to offer advice on occupational safety issues aimed at preventing accidents, having
workers point out unsafe conditions, investigating work-related accidents or "near misses” and measuring hazardous factors
(noise, humidity, temperature, radiation, with the appropriately calibrated instruments etc.).
EMPLOYEE HEALTHCARE
The topic is examined in the "Employment" section of the same chapter.
EMPLOYEE TRAINING
In 2021, as in 2020, no training was provided due to the COVID-19 pandemic. Training was provided only to new hires (meter
readers, engineers, sewerage and water supply workers). The training topics were: Hazardous conditions – Personal Protective
Equipment – Work-related accident – Signage – Legislation.
Trainings offered to water supply and sewerage crews and at water treatment plants were held either in open spaces or indoors
with a maximum of 9 participants, while taking all protective measures against the coronavirus.
Treating training as a factor that helps strengthen corporate culture, some training materials were revised, with “Eydapio”
featuring first. The publication was distributed to employees and explains all of the Company's main activities.

Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
149
SAFETY INFORMATION SIGNS
Safety information signs were posted at all our facilities with clear instructions about the hazards in the various areas and the
required PPE that visitors should wear to be allowed to enter.
PERSONAL PROTECTIVE EQUIPMENT (PPE)
The specifications for PPE were reviewed, revised and updated to comply with the latest European standards. The process is
repeated every year. PPE was distributed to employees, as it is every year.
EVACUATION PLANS
In 2021, the IPPD implemented evacuation plans at EYDAP buildings which did not have one. There are still 13 evacuation plans
to be completed.
OCCUPATIONAL HEALTH ACTIVITIES
As every year, Fit for Work Statements were issued to reflect any changes in EYDAP employee status. In 2021, Fit for Work
Statements were re-issued for more senior employees to bring them up to date.
Statements for employees to stay or change their place of work are issued by EYDAP's Occupational Health Physicians, who
maintain personal health booklets for all employees, after taking into account any health problems diagnosed by employees’
personal physician and any medical tests submitted by the employee.
A vaccination schedule (hepatitis B) is drawn up by IPPD nursing staff for employees working in particularly sensitive areas of
activity (those who work in sewage quality control labs, the sewerage network, and at wastewater treatment plants).
INCIDENT INVESTIGATION
All incidents, regardless of severity or impact, must be reported to the IPPD. Such incidents include near-misses so that
preventive measures can be taken to avoid them in future. A special form for reporting “near-miss” incidents has been posted on
EYDAP's intranet website, “Thalassa”, which is accessible to all employees who wish to submit one.
• The WHSC conducts a risk identification and a hazard assessment control through a documented procedure
within the management system with the aim of documenting all hazard sources, their link with risks they engender, assessing
their threat level and implementing all necessary control measures relative to Health and Safety.
• The results of procedures to assess and continually improve the Occupational Health and Safety Management
System and to document and investigate incidents are used to monitor the achievement of objectives and comprise the OHS
Management System’s performance indicators.
Specifically, the OHS programs are regularly reviewed and updated, along with checking the extent to which set objectives are
met, drawing up timelines and determining those responsible for implementing related actions and the necessary means.
• The IPPD is responsible for drafting and updating WORAs for the entire Company and includes an analysis of
occupational risks per activity for every department in the Company.
• All incidents, regardless of severity or impact, are reported and documented and notified to Company
Management, and the complete record is kept to investigate them so that preventive actions can be taken. A record of reported
incidents is also kept at the Labour Inspectorate.
• The IPPD also maintains statistical analysis data on work-related accidents and incidents to assess and investigate
them and take measures and corrective actions where deemed necessary.
• The IPPD follows a documented procedure on preparedness and response to emergency situations which have
been identified by the Directorate of Administrative Support-Civil Emergency Planning Division (PSEA). It follows specified
actions based on PSEA plans and the procedure for formally notifying the Company to mobilize and remove employees from
their work areas in hazardous situations.
EYDAP PROJECTS IN EAST ATTICA
With the start of sewerage works in East Attica, in the last six months, EYDAP has been working under a contract concluded on
31/8/2021 with occupational safety coordinators who oversee contractors on projects to ensure compliance with laws governing
employee health and safety. These projects involve the installation-construction of sewerage networks and pumping stations in
East Attica, as well as contracts for other works on water supply and sewerage networks.
INITIATIVES - GOALS FOR 2022

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
150
The main goal for 2022 regarding employee health and safety remains consistent:
Zero incidents (as reflected in the Health and Safety Policy Statement) in combination with a strengthened culture of health
and safety amongst staff.
Other goals:
1. Ongoing updates and communication of current regulatory framework for the protection of our employees, associates and
customers in the face of the COVID-19 pandemic. Awareness about fully complying with all health protocols issued by the
Greek National Public Health Organization (EODY). The Company seeks to further safeguard the health of its human
resources and its associates and customers, through continuing compliance with measures specified by the COVID SHIELD
certification scheme to protect against COVID-19.
2. Producing new editions of “Eydapio” Updated information based on more recent risk assessment.
3. In 2022, planning for in-person training on health and safety issues will be undertaken by Safety Technicians and
Occupational Health Physicians, based on the progress of the pandemic during the months April-June (when annual training
is usually held) and in compliance with EODY health protocols. Our aim is to hold training sessions in open spaces while
maintaining safe distancing and wearing masks.
4. The Directorate for Administrative Support-PSEA competent for scheduling evacuation drills is already in consultation with
the supervisors of EYDAP's Regional Centres. The IPPD will then be informed so it can assist with drill supervision.
5. Lastly, the Company is in the process of developing a Corporate Social Responsibility System with the aim of becoming
certified to the SA 8000 standard.
Outcomes of these policies and non-financial key performance indicators
WORK-RELATED ACCIDENTS
The law defines a work-related accident as the insured’s death or inability to work as a result of a serious incident that occurred
while working or as a result of working (while the employee was travelling to the workplace and while returning home).
The IPPD recommends measures and monitors their implementation. Specifically, it recommends, through inspections, the
compliance with laws, use of PPE and general protective measures, observing the Traffic Code, following safety guidelines and
WORAs.

D.6.c HUMAN RESOURCES
Main non-financial risks
As we operate in a sector facing ongoing challenges, both environmental and technological, EYDAP is making efforts to upgrade
its operations and develop a dynamic work environment. Human resources, as a factor of know-how and innovation, are a
significant corporate asset which ensures a business’ endurance and continuity.
Our long-term commitment to supply Attica with top-quality water and to apply best practices for the management of waste
water is made possible through the best possible utilization of our Company’s people, through the staffing of our services with
employees having a high level of know-how, and through the reinforcement of our human resources with new staff members
specializing in areas that are of interest to the Company. The sense of responsibility and commitment of employees is proven
daily in every operation of the Company.
EYDAP'S RESPONSE TO THE COVID-19 PANDEMIC
2021 was a year in which management was also affected by the COVID-19 pandemic. It was defined by our immediate
adjustment to NPHO (National Public Health Organization) guidelines and to the legal and regulatory framework of the Greek
State in order to ensure the uninterrupted and qualitative provision of services to citizens, while also protecting the health of
employees.
The need to cover this emergency situation led to immediate, preventive and effective actions.
• As early as March 2020, when the pandemic first broke out, a Special Crisis Management Team for the coronavirus was
established and a COVID-19 Coordinator was appointed in order to provide employees with guidelines for managing and
dealing with COVID cases.
• The Company’s Medical Healthcare Service strictly observed all prevention measures for the protection of insured parties
and employees.
Corporate policies and due diligence and Outcomes of such policies and non-financial key performance indicators
The Company is committed to
• ensuring the constant development of its employees
• integrating all laws which ensure safe working conditions into its procedures
• equal pay without discrimination
• full health coverage of employees and their insured family members.
At EYDAP
✓ each employee is encouraged to develop personal skills, and through their experience, they provide assistance in actively
shaping proposals, ideas and solutions

OPTIMIZATION PROJECTS
The management of change is a necessity but also an opportunity for businesses to ensure their sustainability by adapting to
the constantly changing business requirements and rapid technological developments.
With the absolute belief that the evolution of the Company is in line with the development of our employees and with the aim of
applying the principles of Sustainable Development, the Company continues its transformation by implementing optimization
projects in the field of Human Resources. The aim is to make optimal use of human resources and of all technological tools and

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
152
processes through the implementation of an advanced new HRMS system which will be able to effectively support both the
current and future needs of the Organization.
The development of a complete Strategic Plan for the Company’s Human Resources and the utilization of its human capital in a
way that is structured and oriented towards its strategic and operational needs is linked to the corresponding adoption of a new
Corporate Culture of constant development of its human resources and achievement of its strategic goals. Thus we move on to
the:
• Development of a plan for the strategic programming of needs in human resources
• Development of a model for optimizing the management of human resources
• Modernization of performance evaluation procedures
• Reallocation of resources
• Management of change and corporate culture
In this framework, and in order to achieve its strategic goals, the Company proceeded to change its organizational structure
with the aim of utilizing the organization’s Human Resources and achieving operational effectiveness.
The following commenced in 2021 and are currently in progress:
1) Updating the organizational chart through internal tender procedures and by notifying all staff via email and
posts on the Company’s internal portal. There were 23 internal tender procedures for the filling of 5 General Manager positions,
24 Manager positions and 51 Head of Service positions. The staffing of the General Manager positions, except one, of the
Manager positions and of certain Head of Service positions was completed within the year. The procedures are still ongoing and
are expected to be completed within 2022.
2) The modernization of the Company’s Human Resources Evaluation System (monitoring and enhancing of
performance, identifying areas that need improvement) with the aim of achieving steady improvement of the company’s results.
RECRUITMENT
The recruitment process for the purposes of covering the needs of the Company is always carried out on the basis of a relevant
legal framework through the Supreme Council for Civil Personnel Selection (ASEP), which ensures the objectivity and
transparency of the process. Given that certain procedures can sometimes be time consuming, EYDAP temporarily covers part of
its needs through the recruitment of contract staff following the announcement of a tender procedure via ASEP.
The restriction of recruitments due to Law 3833/2010 resulted in the constantly decreasing number of employees due to
retirement, the increase in the staff’s average age, the occurrence of the possible risk of having difficulty meeting the ever
increasing needs of the Company in the future, but also the risk of not passing on the existing know-how to younger employees.
This risk was significantly reduced after the announcement of two (2) tenders (1K/2018 and 4K/2018) for the recruitment of 300
individuals with various specializations under open-ended contracts. The final results of the tenders were issued in 2020 and
the recruitment process began immediately, and was continued in 2021 while also strictly observing all measures for dealing
with the pandemic.
From the date of issue of the final results until 31.12.2021, 249 individuals were recruited under open-ended contracts (66
individuals were recruited in the year 2021). During the procedure several resignations occurred and ASEP was asked to
proceed with the replacement of resignations.
The initial recruitment process is expected to be completed in 2022.
Furthermore, following the issuance of a final judgment by the Athens Appeals Court, 5 water distribution regulators were
recruited based on a previous ASEP tender from the year 2009.
The need for new specialized knowledge and the expansion of the Company’s scope of activity (integration of new areas in the
water supply and sewerage network, construction of new projects in East Attica), have made the need for the immediate
further strengthening of existing personnel through the recruitment of regular personnel covering various fields of
specialization even more imperative. Therefore, in 2021 the Ministry of Infrastructure and Transport approved an application by
the Company to recruit 145 individuals from the Lists of Runners-up of ASEP Tenders 1Κ/2018 and 4Κ/2018.
At the same time, in 2021, for the purposes of covering emergency operational needs and following a tender for 8-month fixed-
term employment contracts (ΣΟΧ 1/2020), 102 contract labourers, drivers, measurement technicians, electrical technicians and
mechanical technicians were recruited. Out of these, the contracts of 61 individuals expired within the year.
NUMBER OF FIXED-TERM AND OPEN-ENDED CONTRACT EMPLOYEES
EYDAP has and staffs facilities (regional centres, technical divisions, water treatment plants, aqueducts, etc.) throughout the
Attica basin and also in the Prefectures of Boeotia, Phocis and Aetolia-Acarnania.

WORK ENVIRONMENT
EYDAP implements and observes all the provisions set out in labour legislation.
The Company’s main objective is the rational and objective utilization of its human resources, coupled with personal
improvement and professional development.
In order to reduce the risk of losing know-how, and also to keep abreast of new knowledge, particular emphasis is placed on the
training of all employees. (The issue of Employee Training is analyzed in the corresponding chapter of the same section).
Peace in the workplace is a key concern of the Company. This is achieved with continuous care in order to ensure a healthy,
safe and pleasant working environment, through compliance with the law, staying up to date in order to minimize workplace
accidents, improving existing methods and techniques while also adopting new ones, and strengthening job security among
employees.
Employee rights to equality and safety at work are safeguarded through Collective Bargaining Agreements and compliance
with the legislation on the existence of an Internal Protection and Prevention Service (ESYPP) and of a Committee for the
Health & Safety of Employees (E.Y.A.E.). (The issue of Employee Safety is analyzed in the corresponding chapter of the same
section).
The GRADE AND SALARY PROMOTION of staff depends to a certain degree on the yearly evaluation of employees with the use
of Evaluation Sheets, as foreseen by the Personnel Regulations of EYDAP. However, as of 14/2/2012 and in implementation of
Law 4048/2012, salary promotions (maturity) are no longer provided due to their suspension.
CODE OF ETHICS All employees are required to observe the Code of Ethics, which determines the relationships with each other,
with the Company, with external collaborators and with clients, and also reflects the Company’s policy. There is full compliance
with the Regulatory Framework applying to EYDAP (Rules of Internal Procedure of EYDAP Personnel, the Company’s Rules of
Operation, which are revised based on business needs and changes).
During the year, there were only two cases of fines being imposed due to inadequate observance of the law and, in particular,
due to the violation of the minimum mandatory weekly rest period due to emergency situations.
SUPPORTING YOUTH
EMPLOYING STUDENTS In 2021, in the context of the compulsory internship of ATEI students, 87 students from technological
education institutes either started or completed their internship at the Company’s Services, thus obtaining knowledge and
training in their field of study.
EMPLOYMENT VIA THE NSRF In 2021, 13 students were employed for two months at the Company's facilities and in their field
of study.
These initiatives have been implemented for a number of years and have offered valuable knowledge and a high level of
experience and practical training to a large number of students.
REWARDING CHILDREN OF EMPLOYEES
In 2021 EYDAP continued the reward program for the children of Company employees for their successful admission to Higher
Education Institutions (Universities and Higher Technological Educational Institutes).
EYDAP's initiative aims at the moral recognition of excellence, which comes as a result of methodical and hard work, hoping
that it will serve as an incentive in the course that is to be followed by young people, both in their academic and career paths.
CORPORATE CULTURE
One of the Company’s goals is to strengthen its corporate identity and culture.

To EYDAP, corporate culture is the link between employees, which ensures the achievement of the Company’s mission and
vision, and serves as the common denominator that brings together all employees, making them feel like part of a team with
common goals.
The new corporate culture that is to be developed will embody the corporate values of: Integrity, diversity and inclusion,
respect, cooperativeness, operational excellence, reliability.
The Internal Communication and Culture Service was established in 2021 and was staffed in November of the same year. Our
goal is to develop suitable forms and channels of internal communication. To this end, the monthly electronic magazine “Our
Source” was launched in 2020 and includes corporate news and informative articles on the Company’s actions.
The goal for 2022 is to map the existing corporate culture, use multi-channel communication platforms with the employees and
develop corporate volunteering.
EDUCATIONAL LEVEL OF EMPLOYEES
The smooth and contemporary operation of the Company requires staff with a high level of education and specialised training.
31.14% of employees have Higher Education degrees. Specifically:
• 496 individuals (21.3%) are University Graduates (holding 1 and/or 2 degrees, and/or postgraduate degrees and doctorates)
• 275 individuals (11%) are Technical School Graduates (holding 1 and/or 2 degrees and/or postgraduate degrees).

• a lever of growth for human resources
• an investment, as it is in line with its corporate strategy and business goals
• a condition for corporate development and continuity
• a reinforcing factor of Corporate identity
• a means of dissemination of solid corporate knowledge
• a factor of Sustainability
The Company has a Human Resources Training Directorate, which plans and implements a number of training programs
within the Company, and is certified to the ISO 9001:2015 Quality Management System. For the purposes of implementing the
above programs, it uses the subsidy from the OAED/LAEK program (Manpower Employment Organization - Special Fund for
Employment and Vocational Training) involving a 0.24% refund of employees’ employer contributions.

aims at creating a register of certified internal instructors after taking the examinations held by the National Organisation for the
Certification of Qualifications and Vocational Guidance (EOPPEP), for the purposes of exporting the Company's know-how to
third parties, e.g. Municipalities, Municipal Water Supply and Sewerage Companies (DEYA), etc.
The selection of educational subjects is made taking into account:
• proposals of the individual organizational units
• proposals of the Company Management
• professional development approaches of human resources
TRAINING HUMAN RESOURCES ON PERSONAL DATA PROTECTION
To EYDAP, Personal Data Protection is – apart from the obligation to establish Policies and Procedures – important because it
concerns all its employees, as conveyors of the Company’s guidelines. as such, they are called on to implement the procedures
and properly manage personal data issues which occur while working (communication with consumers and external
collaborators, processing data of other colleagues, etc.).
From the entry into force of the General Data Protection Regulation, targeted training programmes were organised, both in
person and from a distance.
The need for constant staff training became stronger under conditions of teleworking, especially for the purposes of preventing
attacks and recognizing malware, in accordance with the Guidelines of the Hellenic Data Protection Authority under number
32/2021.

Fiscal Year 01.01.2021 – 31.12.2021

In 2021, in collaboration with the Directorate General of Customers, a “Manual with Questions/Answers and Instructions” was
drawn up on issues regarding the management of personal data belonging to customers/consumers and touching on specific
issues that came up during the training of staff from the Directorate General of Customers in the year 2020.
In the framework of issuing Guidelines 1/2021 of the European Data Protection Board (EDPB), the DPO office created a table /
guide of examples in Greek regarding the notification of personal data breaches by practically depicting the casuistry of such
breaches (18 scenarios in 6 groups) and the extent to which a breach requires notification/reporting.
The training was a continuation of the training provided in 2019 and 2020, which involved simulation of situations, thus
achieving – through a specially prepared methodology – the “awareness” set out in the Regulation, placing particular emphasis
on employees in the field of customer service, with the aim of establishing desired user behaviours.
Personnel training/education was carried out through the development of information material via e-mails with tips: on issues
such as personal data protection, malware, social engineering and phishing, mobile devices, use of email, visiting websites,
protecting equipment when on leave or in the case of remote working, further to the training that has already been provided
with the aim of establishing desired user behaviours. The successful staff training efforts via e-learning with tests is continuing
and being further enhanced.
The next goal for 2022 is to continue the interactive staff training process with the aim of assessing their alertness and
understanding of established policies and procedures which the company has integrated in the framework of its regulatory
compliance.
EVALUATION OF TRAINING PROGRAMMES
Each training program is evaluated by the participants. At the end of every six-month training period and with the use of a
questionnaire with open-ended and closed-ended questions, the evaluation is carried out by the involved organizational units
of the Company. In particular, an evaluation was carried out in the first training semester and received very positive feedback for
21 seminars and for 27 seminars in the second semester. Based on the corresponding evaluation form of the ISO 9001:2015
Quality System, the average of evaluations made by trainees and instructors ranges from 8.1 to 9.8 per seminar.
LIFELONG LEARNING
The Company’s willingness to support the lifelong learning and education of its employees is expressed through the
granting, based on the statutory conditions, of paid student leave, while also giving employees the opportunity to take unpaid
educational leave for as long as applied for.
EYDAP provides the opportunity for its employees to obtain a degree, a postgraduate degree or specialization from Higher
Education Institutions, covering most of their tuition fees by providing the statutory student leave (14 or 20 days per year). In
2021, 9 employees applied for and received a tuition subsidy for undergraduate or postgraduate studies in fields related to
economics and management.
EYDAP staff is encouraged to attend events, exhibitions or conferences, whether domestic or international, with full
coverage of the costs for the purpose of keeping abreast of new technologies and new facts in various scientific fields related to
the scope of the corresponding organizational units. In 2021, 51 employees participated in such trainings.
SYNERGIES
The Company is open to innovative ideas coming from Educational Institutions and Research Centres. EYDAP participated
in actions co-funded by the EU, such as: Erasmus+, Horizon 2020 and the program titled: Research - Create - Innovate (2nd
Cycle). It also participates as an Associated Partner in the program titled Erasmus+ (CATALIST) “European VET Excellence Centre
for Leading Sustainable Systems and Business Transformation”.

mobilize for water protection on World Water Day 2021.
EYDAP, on the day, carried out an information campaign on the importance of water through the message "Celebrating our
most valuable source of protection! We invest in the day after!" Through this campaign and with a focus on the excellent
quality of drinking water, the protection of the resource and the best service to its customers, EYDAP sought to raise public

aim is to provide direct, reliable and broad public information on both corporate news and customer service issues.
The development of all EYDAP's pages is mainly achieved organically, with 1 to 2 posts or "stories" per week, reflecting the users'
search for the Company's content on social networks and its general image. Occasionally, to encourage interaction with the
public and proliferation of updates, promoted posts are posted.
In 2021, EYDAP, as part of the broader Digital and Business Transformation, upgraded its mobile application EYDAPP and its
informative website www.eydapp.com.

The Company has an adequate and effective Internal Audit System, in terms of financial and non-financial information, in order
to effectively manage operational risks arising from the conduct of its activities, as well as from changes in the regulatory and
legal framework governing its operation, which may lead to legal sanctions and the imposition of fines for non-compliance.
The IAS reporting model includes the audit environment, risk management, audit mechanisms and safeguards, information,
communication and monitoring system of the IAS, through a set of Principles, Regulations, Policies, Procedures, Safeguards and
organizational structures, designed to provide reasonable assurance as to the accuracy and reliability of accounting and
operational data.
The design of the structure and monitoring of the IAS is based on the adoption of the Three Lines Model, defining roles and
responsibilities in different areas and the relationship between them. The first line consists of the organizational units or
persons whose activity is directly related to the provision of services to the Company's customers and who are holders and
managers of business risks. The second line consists of the Risk Management and Compliance Directorate with a key role in
supporting the Company's management and the Board of Directors in managing risks to achieve the Company's strategic
objectives and the third line consists of the Internal Audit Directorate which has the primary responsibility of reporting to the
Audit Committee and the Board of Directors on the adequacy and effectiveness of the IAS.
Risk Management
The Company recognizes and has included in its Business Risk Register the ESG Risk category. Through an ongoing compliance
program, the Company places particular emphasis on the effective response and management of potential risks and acts to
continuously monitor and update these risks.
Management involves identifying, assessing, monitoring, responding to risks and issuing appropriate system support reports.
The objective of the operational risk management framework is to create transparency through systematic risk management.
The management of these risks aims to:
• Enhancing transparency by adopting common criteria, standards and risk reporting.
• Embedding risk concepts in key business functions.
• Management Support in making important decisions taking into account the willingness to take risks.
• Prioritization of significant risks requiring immediate management intervention.
Systemic risks: as part of the management of these risks, EYDAP has made a record of the audit mechanisms to prevent the
interruption of any production process due to power outages with the availability of alternative sources of energy supply
immediately. The production units have preparedness and contingency plans and carry out regular drills for their staff.
In compliance with the current Regulatory Framework and by decision of the Board of Directors of the Company
• A Risk Management and Regulatory Compliance Division was established in order to develop and implement an
operational risk management framework and to implement all necessary actions for the full and continuous compliance of
the company with the regulatory framework through the adoption and implementation of appropriate and updated Policies
and Regulations.
• A Risk Management Committee was established, consisting of members of the Board of Directors, which reports, through
its Chairman, to the Board of Directors, as well as the Operating Regulations of this Committee, which define its purpose,
jurisdiction, election, composition, powers, responsibilities and mode of operation.
(for a detailed reference to the establishment and functioning of the Committee, please refer to "Corporate Governance"
section of the same Report)
Β. FIGHT AGAINST CORRUPTION
EYDAP recognizes that corruption and bribery undermine the ethical environment of any company and constitute a complex
problem with economic, social, environmental and political implications and therefore adopts Policies and Procedures to combat
it.
The fight against corruption and bribery is an essential and priority issue for EYDAP because it can: a) contribute to the
identification, better assessment and management of risks as well as to regulatory compliance, which is a non-negotiable
principle in all its activities; b) enhance its protection against any fraud, embezzlement and abuse by further strengthening its
transparency and integrity, its credibility and the trust of its stakeholders; and c) serve the business objectives of EYDAP.
Regulatory compliance is a key element of EYDAP's business.

for society and the environment, applying a zero-tolerance policy against corruption and bribery.
The development of proactive anti-corruption measures reduces the risk of fraud and enhances the Company's market value, as
it is a practical demonstration to stakeholders of the commitment to good corporate governance and corporate social
responsibility.
✓ In the context of the "Anti-Corruption and Bribery Policy", which was drafted in accordance with international best business
practices and the specific needs and corporate culture of EYDAP:
• Covered persons are the members of the Board of Directors, senior and top management and all employees of the

corporate environment is carried out through a process of thorough screening and due diligence.
• Covered persons are encouraged to disclose any matter or suspicion of wrongdoing as soon as it comes to their attention
and, in the event of a good faith report, are protected from any acts of retaliation with respect to their position and
advancement. Incidents reported shall be investigated by the Company in an appropriate manner and if confirmed,
corrective action shall be taken.
• Non-compliance may lead to disciplinary action, which may result in dismissal for gross misconduct as, under the
disciplinary provisions of the Company's Personnel Regulations, non-compliance may cause material or moral damage to the
Company. Furthermore, the person involved may be subject to criminal prosecution under the applicable Greek legislation.
✓ The audit mechanisms, which are found in all corporate functions and involve all personnel, consist of a system of policies,
procedures and practices and are applied in relation to the management of existing risks, taking into account the cost-
benefit ratio. These mechanisms concern, inter alia, the standardization of operations and the reduction of exposure to
operational risks. The audit mechanisms applied to information systems also play an important role. This position is based
on the absolute principle of compliance with the requirements of the law and the commitments that the Company has
voluntarily undertaken on the basis of the quality and operational standards it has adopted and the best corporate
practices. The strengthening of the Internal Audit System is a further strengthening of the Company's position and
credibility.
✓ Adoption of a Conflict of Interest Policy: the Company adopts a Conflict of Interest Policy in order to fulfil its obligations to
maintain and implement adequate and effective procedures and audit mechanisms regarding the prevention, identification,
management and response to existing and potential conflict of interest situations, in compliance with the applicable
legislation on corporate governance and the Public Procurement Law. Also, in the context of dealing with situations that
constitute a conflict of interest and ensuring the implementation of the Conflict of Interest Policy, the Company has adopted
a procedure for the submission of a conflict of interest declaration by the covered persons and the signing of a declaration
that they are aware of the content of the aforementioned Policy and that they are committed to complying with its content.
✓ Adoption of a Sponsorship Policy: EYDAP has established and implements a Sponsorship Policy, which identifies the basic
principles of its sponsorship program, as derived from its Strategy and priorities, the characteristics that should govern the
sponsored actions and the beneficiaries, as well as the process that should be followed up to the final stage of their

corporate information on the Company's website, the publication of the Company's financial statements.

effectiveness and quality of the services it provides. Thus, it creates value for the benefit of all its stakeholders and its
Sustainable Development, through a new environment of direct interaction and communication between citizens and the

- Improved information - Timely receipt of reliable data at a common point (single source of truth).
- Access to relevant information, anytime and anywhere
DATA MAPPING
We proceed with the investigation and evaluation of digital data in the Company's information systems in order to organize,
classify - structure and further analyze them with modern tools and security rules.
The above process will help in the early identification, quantification, prioritization and management of risks.
MATURITY IN CYBER SECURITY ISSUES
The digital transformation of EYDAP requires immediate actions to secure and protect the information systems. Based on the
above principle:
• A detailed register of information infrastructure (hardware), software and intangible information assets is created.
• A Penetration Test was conducted on the Company's information systems and an audit of the Company's readiness to
comply with cybersecurity regulatory obligations was conducted by the National Cybersecurity Authority.
• A comprehensive Business Continuity Plan & Disaster Recovery Plan for the Company's information systems is being
prepared.
• A new system for immediate detection and management of breach incidents is launched in collaboration with the Chief
Information Security Officer (CISO).
All the above underline that our Company sets as its top priority the compliance with the Community and national legislative
framework on personal data protection and cybersecurity, as framed by other international standards for the security of
information systems, networks and information.
COOPERATIONS
Cybersecurity Exercises
EYDAP participates in annual cybersecurity exercises under the auspices of the Hellenic National Defense General Staff
(Pantoptis) and in a research proposal, which was accepted for evaluation in the European HORIZON Program, in collaboration
with Democritus, European University Institutions, and other public utilities, in order to create a digital platform that will be
located in a special state structure (e.g. e.g. the General Staff) and will monitor Security Operations Events in order to detect in
time the possibility of a wider malicious threat to critical infrastructure.
Digital Innovation Competition
The Digital Innovation Competition, an original, open competition for technological innovations, announced in November 2020
in collaboration with the EESYP Innovation Network and MIT Enterprise Forum Greece, has reached its final stage.
In total, 162 applications were received from start-ups, teams of scientists, university research centers, etc. in order to offer
innovative solutions to the following two challenges:
- Creating an algorithm that uses historical metering data to predict which water meters are faulty.
- Creating an algorithm that uses historical metering data to predict the future consumption of a supply in the medium term.
After the evaluation of the applications, 76 teams were selected and were placed in a mentorship program by a team of EYDAP
executives to support them in the development of their solutions.
For the challenge of predicting defective meters, 18 teams submitted a solution and more than 350 water meters were replaced
in order to verify in the field whether these meters are defective or not. EYDAP's Water Meters Laboratory was in charge of
carrying out measurements and evaluating them, ranking the solutions with the highest success rate to determine the winning
teams.

For the challenge of predicting consumption of water supplies in the medium term, solutions from 23 groups were submitted,
which were evaluated, assessed and ranked based on the smallest deviation from actual metering data.
The two winning teams of each challenge will receive a cash prize. A framework for cooperation will be proposed to the winners
of the competition, for the pilot implementation of the proposed solution and possibly the development of new functionalities
based on the solution provided.
O2 Hub, a new innovative Open Data & Open API Hub
EYDAP, a member of EESYP's subsidiaries, actively contributed to the collaborative development of the innovative pilot platform
O2 Hub. The pioneering Open Data & Open API Hub, contributes decisively to digital transformation, enhancing transparency
and innovation and is an important tool for universities, research institutions, start-ups, public and private organizations,
ensuring the ability to obtain the necessary data that will help them develop new services and solutions for the benefit of society
as a whole.
EYDAP participates in the O2 Hub pilot operation, making publicly available 6 datasets related to reservoir reserves, drinking
water production at Water Treatment Plants (WTPs), consumption volumes, quality data at the outlet of Wastewater Treatment
Plants (WWTPs), data on new and existing services, as well as data related to customer service centers per region (Regional
Centers).
The aim is to continuously upgrade the Hub and further exploit it as a reference point in the wider ecosystem, by continuously
updating the data and enriching it with more information sets, thus ensuring its usable sustainability and creating the necessary
open data culture.
Outcomes of these policies and non-financial key performance indicators
In the context of the exceptional circumstances created by the Covid-19 pandemic and the needs that arose for remote working,
a series of actions were taken to implement and make available digital solutions to support business processes.
Indicatively:
• Supply and distribution of 340 laptops and computer equipment.
• Implementation of a platform for the provision of virtual workstations to ensure secure remote working. The new
infrastructure (Virtual Desktops Infrastructure) was deployed on cloud infrastructure and effectively assisted in the
execution of remote working.
• Intensified the process of issuing and using digital signatures, resulting in the number of executives with digital signatures
increasing to 505 users by the end of 2021. The extensive use of digital signatures, combined with the digitization of
business processes, has had a positive impact in terms of reducing operational costs and processing time, as well as
enhancing transparency.
• Process automation, with priority given to upgrading the electronic document handling process. In this way, a key business
process of the Company is becoming fully digital (paperless), significantly reducing the time needed to process cases.
• Upgrading of call centers, with the addition of the ability to transfer fixed calls to mobile devices, initially for thirty (30)
executives, but with a program to extend the capability to the responsible persons in critical areas of the Company.
• Development of a series of new corporate security policies and usage regulations for secure remote use of information
systems and equipment.
The new conditions have led a significant part of the staff to adopt a new professional culture, making technological leaps,
embracing new working practices with environmental, economic and social impacts beyond the workplace.

E. 3 PROTECTION OF PERSONAL DATA
EYDAP manages the issue of Personal Data Protection with a view to the continuous compliance of the Company in the light of
the provisions of the General Data Protection Regulation EU2016/679 and the current legislative framework (n4624/2019, n
347/2006), the Guidelines of the Working Group of the European Data Protection Supervisor No. 29 (WP29), the European Data
Protection Board (EDPS), the European Commission, the relevant Directives, Decisions, Opinions of the Data Protection
Authority. In this context, a Data Protection Officer's Office has been established, staffed by individuals with expertise and
knowledge of internal Company procedures, in order to ensure continuous and secure compliance.
The plan of the DPO office for the year 2021 has been formulated in the spirit of balancing the difficult situation that the global
community has been called upon to face as a consequence of the SARS-CoV-2 and COVID-19 pandemic. The trade-off between
the individual rights and personal data of the subjects against the overriding constitutionally based right of all citizens to public
health was great and particularly demanding. The Company was required to take additional measures to inform staff, customers
and enhance security. On the other hand, emphasis was placed on addressing this urgent situation without neglecting the
Company's plan to continuously comply with the provisions of the applicable legal framework for the protection of personal data
of the subjects [customers, staff, partners, suppliers and so on].
With specific reference to the year 2021, the Data Protection Officer, as an advisory agent of the Company, in cooperation
with the relevant service agents, took care of the following actions:
The objective for the year 2022 is to update the Activity File following the change of the Organizational Chart from 1.4.2021, the
simultaneous control of the procedures and the vigilance of the staff on personal data issues.
Although during the reporting period there were a small number of requests-complaints on the part of EYDAP's customers, the
management of these was satisfactory, there were no formal complaints before the competent supervisory authority, except for
one with a positive outcome for the Company, nor were there any relevant fines or reprimands or recommendations for
violation of the provisions of the GDPR.
1. Continuous updating of the Activity File in coordinated cooperation and communication with the executives of EYDAP.
2. Recommendations for corrections of vulnerabilities.
3. Update-completion of relevant forms, official Company documents, recommendations, Annexes, contracts, existing
Policies.
4. Provide legal advice in relation to current legislative developments
5. In the context of entering into partnerships with third parties, when they have the role of the Executor, an audit of the
technical and organizational measures they take to safeguard personal data before signing the respective contract was
carried out.
6. Management of customer/employee complaints/claims.
7. Updating the terms and policies of the www.eydap.gr website and eydap.gr application.

8. Updating and strengthening of Data Protection Policies in the context of: secure conduct of EYDAP General Meetings by
technical and audio-visual means, use of special applications by consumers, anonymized surveys with EYDAP employees
and customers as participants, development of internal complaint management systems [whistleblowing], CCTV, internal
evaluations of positions of responsibility, tender procedures.
9. Audit of personnel and non-staff auditing procedures of vaccination certificates, recovery certificates and/or certificates of
conducting screening tests for coronavirus.
10. Drafting guidelines for remote working.
11. Formulating opinions and guidelines on enhancing physical and technical security, restricting access to certain activities and
minimizing use of data in procedures and forms involving customer personal data.
12. Providing clear instructions and guidance to managers and staff as to the proper management of customer data and the
handling of potential breach incidents.
Training of our staff on data protection issues is an ongoing process.
Our goal for 2022 is the updating of the Activity File following the change of the Organization Chart from 1.4.2021, the update of
procedures and the awareness of employees in matters relating to personal data.
Although during the reporting period there was a small number of request-complaints on behalf of EYDAP customers, their
management was satisfactory. There were no formal complaints before the competent Authority, apart from one with a positive
outcome for the Company, nor were any fines imposed or reprimands or recommendation for violation of provisions of the
GDPR.

of digital transformation in chapter E.2. education of our employees on the issue in chapter D.6.c of the same report.)
E.4 ECONOMIC PERFORMANCE & DEVELOPMENT
(material issue)
Main non-financial risks
For EYDAP, positive financial performance by ESG criteria is the practical application of ethical entrepreneurship and continuity
and at the same time the decisive factor for the implementation of the company's transformation and, by extension, its strategic
objectives, while satisfying all its stakeholders.
EYDAP identifies, categorizes and scores risks and implements preventive action plans (credit risk, liquidity risk, market risk,
regulatory risk, etc.) as part of its financial strategy. The existence of a risk management framework is central and the
monitoring process is structured, continuous and ongoing. The risks identified and their management is detailed in the Annual
Financial Report, page 36-42.
Corporate policies and due diligence
2021 was marked by the agreement between EYDAP and the Greek State for the right to provide clean water which services
was extended until 2040. With the signing of the Agreement, which - among other things - also determines the price of the sale
of untreated water from the Greek State to EYDAP for the next 20 years, a long-standing issue was finally closed, which now
allows the Company long-term visibility and the flexibility to implement its strategic plan.
The agreement with the Greek State secures the future of the Company and creates new conditions for its growth and
transformation. It vindicates the work and experience of the people of EYDAP, laying the foundations for this experience to be
further leveraged in new value-added activities for the benefit of all.
EYDAP operates in accordance with the Corporate Governance Code, the National and Community Law (Tax Law, International
Financial Reporting Standards - a detailed reference has been made on the page 46 of the Financial Report), the Internal
Operating Regulations and is subject to regular audits by Certified Public Accountants. As a result of compliance, no fines have
been imposed in relation to the Company's financial activities. (GRI 419-1 )
As part of its transformation, the Company is implementing:
• A targeted strategy to rationalize resources by identifying areas with room for optimization
• Actions to make optimal use of its human resources, processes and technology tools
• A sophisticated new HRMS system to support the Company's current and future needs

E.5 SUPPLY CHAIN
Main non-financial risks
To EYDAP, supply chain management is directly linked to the shaping and implementation of all actions and activities related to
supply, production and distribution procedures, and also to the full coordination of involved parties in all stages of material flow,
through the adoption of sustainable strategies.
Taking into account the direct and indirect consequences that climate change and the pandemic have on global conditions, as
well as the short-/long-term instability of local and international markets, EYDAP examines the potential operational risks it
runs, and mainly the financial, functional and reputational risks, and it adopts and applies sustainable practices and an
integrated approach for identifying, assessing and minimizing them via suitable control mechanisms, in order to deal with chain
reactions caused by any extended adverse circumstances.
The supply network involves the procedures of:
1. materials supply, storage and distribution
2. transport management through the management, programming and maintenance of vehicles and machinery
3. service provision

Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
176
Covering the needs of the supply chain is done both by the domestic and the international market, and in full harmonization
with the National Legal Framework on Public Procurement, as defined by Law 4412/16, as amended and in force (Government
Gazette A 147/08-08-2016), the Public Procurement of Works, Supplies and Services (adaptation to Directives 2014/24/EU and
2014/25/EU), the secondary institutional framework, and EYDAP’s Procurement and General Services Regulation.
The Company, anticipating the possible risks from the non-implementation of Law 4412/2016 and its continuous amendments,
has responsibly taken a series of actions aimed at their timely and effective management. The biggest challenge involves the
adaptation of internal procedures to the continuous amendments of the provisions of Law 4412/2016.
An equally serious challenge and imperative required by law involves the level of compliance of cooperating suppliers / service
providers with Law 4412/2016.
The legal and contractual obligations, as well as the ethical principles that govern the operation of EYDAP require the
observance of the confidentiality of sensitive information and data concerning the Company and its suppliers / service
providers, in accordance with the provisions of the relevant law "on Privacy".
In 2021, there were no instances of acts or omissions raising risks of regulatory compliance and there were no incidents of
non-compliance on the part of EYDAP, in its capacity as the awarding body, during the procurement and service tender
procedures.
As regards the observance of current legislation by suppliers / service providers, in 2021 there were five (5) incidents of
breach of the terms and conditions of contracts (due to the inability to fulfil contractual obligations, the corresponding letters of
guarantee were forfeited). There were no other cases of recidivism, breach of obligations or violation of labour and insurance
laws and, consequently, termination and forced termination of a contract.
In full implementation of its Policy against Corruption and Bribery, EYDAP shows zero tolerance and is committed to operating
with professionalism, legality and integrity in all its professional dealings.
In the same year, there was no violation of the provisions concerning:
• child labour,
• forced labour,
• participation in a criminal organization,
• bribery and corruption,
• fraud,
• committing acts of terrorism or, more generally, committing crimes linked to terrorist organizations,
• money laundering by suppliers environmental legislation and climate change
By incorporating in its Contracts the terms and conditions for compliance of Suppliers / Service Providers with the principles
of the UN Global Compact in the fields of Human Rights, Labour, Environment and Corruption, EYDAP ensures that all
Suppliers / Service Providers of the Supply Chain apply practices that promote respect for human rights and are in line with
the Company's policies on social, labour and environmental issues.
The aim is to ensure the full and timely harmonization and alignment of EYDAP with regulatory procedures, always with
emphasis on reliability, transparency, consistency and the principles of sound administration.
TENDER PROCEDURE
The tender procedure is carried out according to strict rules and includes the notice of the tender, the establishment of
commonly accepted Technical Specifications, the nomination of the lowest bidder based on award criteria and the signing of the
relevant Contract.
EYDAP concludes public contracts with its suppliers taking into account:
• their suitability to exercise their professional activity,
• their economic and financial capacity,
• their technical and professional ability,
• their compliance with quality assurance and environmental management standards,
• their compliance with the provisions of the legislation on health and safety of workers, and their obligations in the fields of
social security and labour law,
• their compliance with the legal framework concerning transparency and protection of personal data.
The Company places special emphasis on attracting new economic operators through the posting of Notices:

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
177
• in the Electronic Online Depository of Administrative Acts (DIAVGEIA),
• in the Central Electronic Public Procurement Registry (KIMDIS),
• in the National Electronic Public Procurement System (ESIDIS),
• in the Annex to the Publications of Notices in the Official Journal of the European Union ,
• on the website of EYDAP S.A. (http://www.eydap.gr).
LONG-TERM AGREEMENTS: With regard to long-term agreements, it should be noted that they are compatible with the
principles of free competition subject to the following conditions:
• that they have been concluded following tender procedures,
• that the technical specifications of the products or services are clear and detailed,
• that they are governed by the mutual obligations and rights of the parties and
• that they are checked periodically to see if they remain competitive.
TENDER PROCEDURES OF GREAT IMPORTANCE: When it comes to tender procedures of great importance and high cost,
EYDAP publishes these tenders at European level in order to ensure the participation of important suppliers operating both in
the domestic and European business scene, thus ensuring the development of healthy competition which leads to the
achievement of a significant financial benefit for the Company. Recent examples are the large tender procedures for the
operation and maintenance of the Psyttalia Wastewater Treatment Plant and the provision of postal services for the collection,
transport, sorting and distribution of EYDAP postal items in which domestic and foreign corporate schemes with strong
corporate presence participated, and from whose participation EYDAP expects to gain both financial and other benefits.
The purpose and goal of EYDAP is to manage its needs in a timely, qualitative and economical manner, with the best terms and
conditions for the contracting parties.
In 2021, the following were concluded:
• 351 Contracts between EYDAP and suppliers / service providers, with a total value of approximately 95.2 million euros plus
VAT, of which 70 involved supplies and 281 involved services
• 213 Private Agreements for Amendment or Termination of Contracts.
• 6 Works Contracts worth a total value of approximately 89.5 million euros plus VAT
• 11 Design Contracts and Contracts for the Provision of Technical and Other Related Scientific Services worth a total value of
1.4 million euros.
STAFF EDUCATION AND TRAINING in order to stay abreast of the constantly expanding and ever-changing contemporary
institutional framework governing the procedures for concluding supply and services contracts.
The consistent adaptation of internal procedures to the constant amendments of the provisions of Law 4412/2016 and,
consequently, the immediate and universal application of both existing terms and any amendments to the institutional
framework of public procurement contracts are achieved through continuous training of the staff members involved in all areas
of its activity through specialized seminars.
In accordance with Article 344 of Law 4412/2016 (as amended by Law 4782/2021, Article 133) on the “Training and Certification
of Awarding Authorities/Bodies”, EYDAP, as an Awarding Body, is required to provide its staff, which has been tasked with the
exercise of duties coming under the above law, continuous education and training in public procurement contracts through
accredited programs.
From 2016, which is the year in which Law 4412 entered into effect, until today, the Company has implemented a series of
specialized seminars and training programs.
In 2021, 42 individuals, the staff of the Procurement and Project Management Directorate and of the Strategic Procurement
and Project Planning Directorate was certified to the Procedures for the Preparation, Conclusion and Execution of Public
Procurement Contracts, in accordance with Book II of Law 4412/2016 applied by EYDAP.
At the same time, in July 2021, upon the entry into effect of EYDAP’s new Procurement and General Services Regulation, the
company started the first cycles of seminars and is continuing its staff training, having set the following training goals:
The acquisition of knowledge, skills and abilities by the staff of the Procurement and Project Management Directorate ensures
the reliability of the procedure, thus giving the Company a competitive advantage.
OPTIMISATION PROJECTS
Through strict observance of the fundamental principles governing the procedure and mainly the principles of equal treatment,
the development of sufficient competition, good administration, and transparent and optimal management of available
resources in a timely and valid manner, in accordance with the best terms and conditions for the contracting parties, the
optimization projects aim at restructuring the supply chain at the level of organization, operations, storage, transport and
inventory network, optimization of operating expenses, increase of efficiency and acceleration of procedures.
These include:
• The design of a new, functional supply chain model

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
178
• Redesign of the network and storage areas
• Transport/fleet management
• A supply model optimization program and reduction of the cost of supplied goods
The following have been scheduled for the achievement of the objectives of 2021:
1. PREPARATION AND IMPLEMENTATION OF THE NEW PROCUREMENT AND GENERAL SERVICES REGULATION.
By monitoring the developments and demands of modern management principles, and in the framework of achieving its
company objectives for the maximum possible increase of business efficiency (flexibility in the method of awarding and
executing contracts, the development of new models of procurement and inventory management), EYDAP has proceeded to
prepare and implement a new, flexible Procurement and General Services Regulation (excluding Projects).
The Procurement and General Services Regulation was unanimously approved by EYDAP’s Board of Directors and, following the
unanimous agreement of the Hellenic Single Public Procurement Authority (HSPPA) under decision number Γ4/2021, has been in
force since 1 July 2021. The implementation of the Procurement and General Services Regulation addresses the legislative gap
arising from the amendment of Law 4412/2016 and restores the regulatory framework applied by EYDAP for the conclusion of
public procurement and service contracts accordingly.
As regards the projects, the preparation of the Regulation on Projects, Designs, Technical and Other Related Scientific Services
is currently in progress.
2. PREPARATION OF A REGULATION ON THE HOLDING OF TENDERS FOR THE DIVESTMENT / SALE OF EYDAP’S
REDUNDANT OR OLD MATERIALS
The new Regulation was prepared for the purpose of improving the management of inventories and is applied in cases of sale of
any redundant or old materials, movable assets and consumables of the Company. The basic rationale behind this strategy is
that the above do not constitute a useless burden but a valuable resource which, if utilised properly, can provide multiple
benefits with a positive financial and environmental impact.
3. REDESIGN OF THE TRANSPORT SERVICE TARGET OPERATING MODEL (TOM), PREPARATION OF FLEET MANAGEMENT
SPECIFICATIONS AND STRATEGIC ALLOCATION DESIGN TO MEET TRANSPORT NEEDS
In the framework of its broader operational plan, EYDAP has drawn up the specifications for a project involving three
interconnected phases which form the general framework of its transportation needs, including the company’s leased vehicles
and machinery.
The Fleet Management Project began in 2021 and aims at the constant monitoring of vehicles through the installation and proper
operation of an integrated system.
The aim is to ensure the efficiency of operations through the use of cutting-edge tools and the simultaneous programming of
assets and resources so as to cover transport needs, given the ever-changing needs in terms of corrective and scheduled
maintenance.
4. PROCUREMENT OF INNOVATIVE MATERIAL FOR IMPROVING EMISSIONS FROM EYDAP’S PRIVATELY-OWNED FLEET OF
VEHICLES AND MACHINERY
In the framework of achieving more sound and environmentally-friendly management of vehicles and machinery, EYDAP has
proceeded with the pilot application of an innovative material, the Environmental Fuel Additive , which derives from the sector
of fossil fuel technology, with the aim of reducing the carbon footprint caused by internal combustion engines.
The use of the Environmental Fuel Additive drastically reduces
• Black Carbon (PM, CO, HC), which is the second largest man-made contributor to Climate Change and has 2/3 of the
climate impact of CO
2
. It also reduces the consumption of liquid fossil fuels, as well as carbon dioxide (CO
2
) and nitrogen
oxide (NO
x
) emissions to a corresponding degree, and also
• fuel consumption, resulting in the further percentage decrease in emission rates, including CO
2
(carbon dioxide) and NO
x
(nitrogen oxides), without increasing the concentration (ppm) in the volume of the remaining fuel products and without
creating any new emissions.
The results of the pilot application indicated:
• improvement of pollutant levels
• reduction of fuel
• reduction of exhaust emissions
• reduction of operating costs
• saving of resources

Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
179
With the aim of achieving more effective management of its fleet of vehicles and machinery, the extension of its use to include
all fuel stations and all EYDAP’s vehicles and machinery was approved in early 2022.
5. GENERAL REFORM OF EYDAP’S SUPPLY CHAIN NETWORK IN THE FRAMEWORK OF AMENDING THE COMPANY’S
ORGANISATIONAL CHART
With regard to the Company’s Supply Chain, the reform – on an entirely new base – of the supply chain's activities was
completed in 2021, with the aim of improving its function as a strong contributor to its operational activities as a whole.
In this framework, the Strategic Procurement and Project Planning Directorate was created in order to improve its approach
and strategy in matters pertaining to the award and execution of works contracts, design contracts, as well as product
procurement and service provision contracts.
The basic goals of the new organisational unit include a feasibility check, which will not only be based on financial criteria but
also on social and environmental criteria, as well as contemporary approaches. These goals have been planned over a horizon of
three years in order to achieve:
• economies of scale
• attraction of small and medium-sized enterprises
• strengthening of the Company’s image
• dealing with potential risks
• sustainable environmental, social and economic development
F. TAXONOMY
The EU Taxonomy Regulation ("the Regulation") constitutes one of the tools established under the European Green Deal, which
aims to achieve the European Union's climate neutrality by 2050. The Regulation establishes the criteria for determining
whether an economic activity is environmentally sustainable, in order to determine the extent to which an investment is
environmentally sustainable. The Regulation creates a common language that investors can use when investing in projects and
economic activities that have a significant positive impact on the climate and the environment.
Taxonomy Regulation 2020/852/ΕU
The "Taxonomy Regulation" 2020/852 / EU is supplemented by the "Delegated Regulation 2021/2178 / EU" and the "Delegated
Regulation 2021/2139 / EU".
In order an economic activity to be characterized as environmentally sustainable, it should:
• contributes substantially (complies with the technical control criteria) to at least one of the following six environmental
objectives:
1. Mitigating climate change
2. Climate change adaptation
3. Sustainable use and protection of water and marine resources
4. Transition to a circular economy
5. Prevention and control of pollution
6. Protection and restoration of biodiversity and ecosystems
• do not significantly harm (DNSH) any of the other five environmental objectives
• is exercised in accordance with the minimum safeguards in relation to the OECD Guidelines for multinational enterprises and
the United Nations guidelines for business and human rights, including the principles and rights that are defined in the eight
fundamental agreements which are specified in the declaration of the International Labor Organization for the fundamental
principles and labor rights and the International Charter of Human Rights
In the delegated Regulation 2021/2139 / EU, published on 4 June 2021, the technical control criteria are enacted for determining
the conditions under which an economic activity is considered to contribute significantly to the first two environmental
objectives: climate change mitigation and climate change adaptation. This Regulation also defines the conditions for determining
whether this economic activity does not significantly burden any of the other environmental objectives.

Article 8, paragraph 1 of Regulation 2020/852/EU stipulates that companies required to disclose non-financial information
(according to Directive 2013/34/EU), should disclose additional information regarding with the way and to what extent their
activities are linked to environmentally sustainable economic activities, as defined by this Regulation.
More specifically, on the basis of the delegated Regulation 2021/2178 EU (Article 10, paragraph 2) for the disclosure that will
take place in the year 2022 and refer to the financial year 2021 (without the obligation of comparative information for 2020),
arises for non-financial enterprises the obligation to publish the percentage of eligible and ineligible for the taxonomy of
economic activities, in relation to the following key performance indicators:
o Turnover
o Capital Expenditures (CapEx) and,
o Operational Expenditures (OpEx)
on the total turnover, of capital and operating expenses.
For the disclosures that will take place in the year 2023 and will refer to the financial year 2022, the obligations will be increased,
as the companies will have to disclose -among other things- if their eligible financial activities are aligned with technical criteria
of the Regulation.
Accounting policy for the determination of key performance indicators (KPI)
Turnover
The percentage of turnover is calculated as the part of net turnover derived from products or services, which are related to
taxonomy eligible economic activities (numerator), divided by the net amount of turnover (denominator). Turnover covers
revenue recognized in accordance with International Financial Reporting Standard (IFRS) 15.
The turnover does not include any intra-group transactions and specifically the transactions between EYDAP SA and its
subsidiary, EYDAP NISON SA.
Capital Expenditures (CapEx)
The percentage of capital expenditure referred to in Article 8, paragraph 2, (b) of Regulation (EU) 2020/852 shall be calculated as
the numerator divided by the denominator as defined in points 1.1.2.1 and 1.1.2.2 of Annex I to the delegated regulation (EU)
2021/2178.
Denominator
The denominator shall cover the additions to tangible and intangible assets during the financial year considered before
depreciation and any revaluations, including those arising from revaluations and impairments, for the relevant financial year and
excluding changes in fair value. The denominator also covers additions to tangible and intangible assets arising from business
mergers.
For non-financial corporations applying International Financial Reporting Standards (IFRS), as approved by Regulation (HCMC)
No. 1126/2008, capital expenditures cover expenditures accounted for on the basis of:
a) IAS 16 Property, Plant and Equipment, paragraph 73 (e) (i) and (iii)·
a) IAS 38 Intangible Assets (paragraph 118) (e) (i)·
c) IFRS 16 Leases, paragraph 53 (h).
Numerator
The numerator is equal to the part of the capital expenditure included in the denominator and is any of the following:
(a) related to assets or procedures related to taxonomic eligible economic activities
(b) part of a plan to extend taxonomic eligible economic activities
Operational Expenditures (OpEx)
The percentage of operating expenditure referred to Article 8, paragraph 2, (b) of Regulation (EU) 2020/852 shall be calculated
as the numerator divided by the denominator as defined in points 1.1.3.1 and 1.1.3.2 of Annex I to the delegated regulation (EU)
2021/2178.
Denominator
The denominator covers direct non-capitalized costs related to research and development, building renovation measures, short-
term lease, maintenance and repair, as well as any other direct costs related to the day-to-day maintenance of property, plant
and equipment by the company or third party, which are assigned the activities necessary to ensure the continuous and efficient
operation of these assets.
Numerator

Fiscal Year 01.01.2021 – 31.12.2021
181
The numerator is equal to the share of operating costs included in the denominator and related to assets or processes related to
taxonomic eligible economic activities, including education and other human resource adjustment needs, and direct non-
capitalized expenditure representing research and development;
Research and development expenditures that have already been taken into account in the KPI capital expenditures are not
counted as operational expenditures.
Eligible economic activities
The eligible taxonomic economic activities of EYDAP SA for the financial year 2021 include:
• 4.1. Electricity generation using solar photovoltaic technology
• 4.5. Electricity generation from hydroelectric power
• 5.1. Construction, expansion and operation of water collection, treatment and supply systems
• 5.3. Construction, expansion and operation of sewage collection and treatment systems
In addition to the above activities, part of the energy needs of EYDAP in sewage treatment centers, is covered by the energy
utilization of biogas produced by anaerobic digestion of sewage treatment sludge. This activity does not generate revenue for
the company and for this reason; it is not reflected in the table below as a separate economic activity. The capital expenditures
as well as the operational expenditures of the specific activity are integrated in the respective indicators of the economic
activity.

In July 2011 the company “EYDAP NISON SA” was established. EYDAP owns 100% of EYDAP NISON S.A. share capital. The
aforementioned subsidiary’s current title is "NISON DEVELOPMENT SEWERAGE SOCIETY ANONYME" and distinctive title "EYDAP
NISON DEVELOPMENT SA".
EYDAP provides its water supply services through its 14,000 kilometers water distribution network. The Company also operates
four Units of Water Refining with a total daily capacity of 1.8 million cubic water meters. In 2018, the Company received under
its possession new networks, namely the remaining water supply network of Salamina, the municipal network of Magoula from
the Municipality of Elefsina and the Municipal Network of Agios Dimitrios area of the Municipality of Penteli-Vrilissia. In 2019,
EYDAP launched procedures and interventions for the smooth integration of these municipal water supply networks into its own
network.. The served population is 4,400,000 inhabitants.
The sewerage network has a total length of 8,500 kilometers. The system is separate (drainage ducts - rainwater pipes), except
for the area of the center of Athens, where the system is pervasive (common ducts of rain and rainwater). The served population
is 3, 695,000 inhabitants. Sewage collection is carried out with the secondary drainage network pipelines of the sewerage areas
through the connections to those ones of each downstream property.
With regard to the waste management, EYDAP SA possesses three waste management centers (WMC):
• The WMC of Psitalia has a processing capacity (average design flow) of 1,000,000 m3 / day of waste water
(currently the average flow of incoming waste is of 730,000 m3 / day)
• The WMC of Metamorphosis has a processing capacity of 44,000 m3 / day of waste water (20,000 m3 / day urban
waste water and 24,000 m3 / day urban sewage). (Today the average supply of incoming sewage is at the level of 12,000 m3 /
day and its sewage of 12,000 m 3 / day); and
• The WMC of Thriasio has a processing capacity (average design flow) of 21,000 m3 / day of sewage (currently, the
average intake of incoming sewage is at the level of 6,000 m3 / day).
The Waste Management Center (WMC) in Psitalia also operates three Electrical and Thermal Energy Co-production units (ETEC).
The one ETEC unit operates with the combustion of natural gas of electrical power 12.9 MWe and thermal power of 17.3 MWth
respectively. The other two ETEC units operate with the combustion of biogas of total electrical power of 11.4 MWe (7.14 MWe
& 4.25 ΜWe) and thermal power of 17.2 MWth, as well as a small-scale hydroelectric station of 489 KW capacity for the
recovery of the contained energy in the wave of processed outflows prior to their disposition in Saronikos Gulf.
Through the operation of the Waste Management Center (WMC) in Psitalia, EYDAP has been incorporated in the EU System of
Greenhouse Gas Emission Allowance Trading, applying the relative EU and national legislation.
In addition, EYDAP manages the sewerage projects of Eastern Attica for the collection and treatment of urban waste water and
the re-use-disposal of treated effluents. In 2020, significant progress was made in the implementation of sewage projects in
Eastern Attica. The design of construction and operation of integrated wastewater management systems in Eastern Attica
includes projects in areas of the Municipalities of Rafina-Pikermi, Spata-Artemida, Marathon, Pallini, Paiania, Saronic and Kropia.

2. NEW STANDARDS, INTERPRETATIONS AND AMENDMENT TO THE EFFECTIVE STANDARDS
Adopting New and Revised International Standards
New standards, amendments to standards and interpretations have been issued and are mandatory for annual accounting
periods beginning on or after 1 January 2021.
Unless otherwise stated in the other amendments and interpretations that apply for the first time in 2020, they have no impact
on the consolidated financial statements. The company and the Group Company have not proceeded with early adoption of any
standards, interpretations or amendments issued by IASB and adopted by the European Union but not mandatory applied for FY
2021.
Χ.1 New Standards, Interpretations, Revisions and Amendments to existing Standards that are effective and have been
adopted by the European Union
The following new Standards, Interpretations and amendments of IFRSs have been issued by the International Accounting
Standards Board (IASB), are adopted by the European Union, and their application is mandatory from or after 01/01/2021.
• Amendments to IFRS 4 “Insurance Contracts” – deferral of IFRS 9 (effective for annual periods starting on or after
01/01/2021)
In June 2020, the IASB issued amendments that declare deferral of the date of initial application of IFRS 17 by two years, to
annual periods beginning on or after January 1, 2023. As a consequence, the IASB also extended the fixed expiry date for the
temporary exemption from applying IFRS 9 “Financial Instruments” in IFRS 4 “Insurance Contracts”, so that the entities are
required to apply IFRS 9 for annual periods beginning on or after January 1, 2023. The amendments do not affect the
consolidated/ separate Financial Statements.
• Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16: ”Interest Rate Benchmark Reform – Phase 2” (effective for
annual periods starting on or after 01/01/2021)
In August 2020, the IASB has finalized its response to the ongoing reform of IBOR and other interest benchmarks by issuing a
package of amendments to IFRS Standards. The amendments complement those issued in 2019 and focus on the effects on
financial statements when a company replaces the old interest rate benchmark with an alternative benchmark rate as a result of
the reform. More specifically, the amendments relate to how a company will account for changes in the contractual cash flows
of financial instruments, how it will account for a change in its hedging relationships as a result of the reform, as well as relevant
information required to be disclosed. The amendments do not affect the consolidated/ separate Financial Statements.
• Amendments to IFRS 16 “Leases”: Covid-19 – Related Rent Concessions beyond 30 June 2021 (effective for annual
periods starting on or after 01/04/2021)
In March 2021, the IASB issued amendments to the practical expedient of IFRS 16, that extend the application period by one year
to cover Covid-19-related rent concessions that reduce only lease payments due on or before 30 June 2022. The amendments do
not affect the consolidated/ separate Financial Statements.
Χ.2 New Standards, Interpretations, Revisions and Amendments to existing Standards that have not been applied yet or have
not been adopted by the European Union
The following new Standards, Interpretations and amendments of IFRSs have been issued by the International Accounting
Standards Board (IASB), but their application has not started yet or they have not been adopted by the European Union.
• Amendments to IFRS 3 “Business Combinations”, IAS 16 “Property, Plant and Equipment”, IAS 37 “Provisions,
Contingent Liabilities and Contingent Assets” and “Annual Improvements 2018-2020” (effective for annual periods
starting on or after 01/01/2022)
In May 2020, the IASB issued a package of amendments which includes narrow-scope amendments to three Standards as well as
the Board’s Annual Improvements, which are changes that clarify the wording or correct minor consequences, oversights or
conflicts between requirements in the Standards. More specifically:

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
195
- Amendments to IFRS 3 Business Combinations update a reference in IFRS 3 to the Conceptual Framework for Financial
Reporting without changing the accounting requirements for business combinations.
- Amendments to IAS 16 Property, Plant and Equipment prohibit a company from deducting from the cost of property, plant
and equipment amounts received from selling items produced while the company is preparing the asset for its intended use.
Instead, a company will recognize such sales proceeds and related cost in profit or loss.
- Amendments to IAS 37 Provisions, Contingent Liabilities and Contingent Assets specify which costs a company includes
when assessing whether a contract will be loss-making.
- Annual Improvements 2018-2020 make minor amendments to IFRS 1 First-time Adoption of International Financial
Reporting Standards, IFRS 9 Financial Instruments, IAS 41 Agriculture and the Illustrative Examples accompanying IFRS 16
Leases.
The Group will examine the impact of the above on its Financial Statements, though it is not expected to have any. The above
have been adopted by the European Union with effective date of 01/01/2022.
• IFRS 17 “Insurance Contracts” (effective for annual periods starting on or after 01/01/2023)
In May 2017, the IASB issued a new Standard, IFRS 17, which replaces an interim Standard, IFRS 4. The aim of the project was to
provide a single principle-based standard to account for all types of insurance contracts, including reinsurance contracts that an
insurer holds. A single principle-based standard would enhance comparability of financial reporting among entities, jurisdictions
and capital markets. IFRS 17 sets out the requirements that an entity should apply in reporting information about insurance
contracts it issues and reinsurance contracts it holds. Furthermore, in June 2020, the IASB issued amendments, which do not
affect the fundamental principles introduced when IFRS 17 has first been issued. The amendments are designed to reduce costs
by simplifying some requirements in the Standard, make financial performance easier to explain, as well as ease transition by
deferring the effective date of the Standard to 2023 and by providing additional relief to reduce the effort required when
applying the Standard for the first time. The Group will examine the impact of the above on its Financial Statements, though it is
not expected to have any. The above have not been adopted by the European Union. The above have been adopted by the
European Union with effective date of 01/01/2023.
• Amendments to IAS 1 “Presentation of Financial Statements” (effective for annual periods starting on or after
01/01/2023)
In February 2021, the IASB issued narrow-scope amendments that pertain to accounting policy disclosures. The objective of
these amendments is to improve accounting policy disclosures so that they provide more useful information to investors and
other primary users of the financial statements. More specifically, companies are required to disclose their material accounting
policy information rather than their significant accounting policies. The Group will examine the impact of the above on its
Financial Statements, though it is not expected to have any. The above have been adopted by the European Union with effective
date of 01/01/2023.
• Amendments to IAS 8 “Accounting Policies, Changes in Accounting Estimates and Errors: Definition of Accounting
Estimates” (effective for annual periods starting on or after 01/01/2023)
In February 2021, the IASB issued narrow-scope amendments that they clarify how companies should distinguish changes in
accounting policies from changes in accounting estimates. That distinction is important because changes in accounting estimates
are applied prospectively only to future transactions and other future events, but changes in accounting policies are generally
also applied retrospectively to past transactions and other past events. The Group will examine the impact of the above on its
Financial Statements, though it is not expected to have any. The above have been adopted by the European Union with effective
date of 01/01/2023..
• Amendments to IAS 1 “Classification of Liabilities as Current or Non-current” (effective for annual periods starting on or
after 01/01/2023)

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
196
In January 2020, the IASB issued amendments to IAS 1 that affect requirements for the presentation of liabilities. Specifically,
they clarify one of the criteria for classifying a liability as non-current, the requirement for an entity to have the right to defer
settlement of the liability for at least 12 months after the reporting period. The amendments include: (a) specifying that an
entity’s right to defer settlement must exist at the end of the reporting period; (b) clarifying that classification is unaffected by
management’s intentions or expectations about whether the entity will exercise its right to defer settlement; (c) clarifying how
lending conditions affect classification; and (d) clarifying requirements for classifying liabilities an entity will or may settle by
issuing its own equity instruments. Furthermore, in July 2020, the IASB issued an amendment to defer by one year the effective
date of the initially issued amendment to IAS 1, in response to the Covid-19 pandemic. The Group will examine the impact of the
above on its Financial Statements, though it is not expected to have any. The above have not been adopted by the European
Union.
• Amendments to IAS 12 “Income Taxes: Deferred Tax related to Assets and Liabilities arising from a Single Transaction”
(effective for annual periods starting on or after 01/01/2023)
In May 2021, the IASB issued targeted amendments to IAS 12 to specify how companies should account for deferred tax on
transactions such as leases and decommissioning obligations – transactions for which companies recognise both an asset and a
liability. In specified circumstances, companies are exempt from recognising deferred tax when they recognise assets or liabilities
for the first time. The amendments clarify that the exemption does not apply and that companies are required to recognise
deferred tax on such transactions. The Group will examine the impact of the above on its Financial Statements, though it is not
expected to have any. The above have not been adopted by the European Union.
• Amendments to IFRS 17 “Insurance contracts: Initial Application of IFRS 17 and IFRS 9 – Comparative Information”
(effective for annual periods starting on or after 01/01/2023)
In December 2021, the IASB issued a narrow-scope amendment to the transition requirements in IFRS 17 to address an
important issue related to temporary accounting mismatches between insurance contract liabilities and financial assets in the
comparative information presented when applying IFRS 17 “Insurance Contracts” and IFRS 9 “Financial Instruments” for the first
time. The amendment aims to improve the usefulness of comparative information for the users of the financial statements. The
Group will examine the impact of the above on its Financial Statements, though it is not expected to have any. The above have
not been adopted by the European Union.
3 SIGNIFICANT ACCOUNTING POLICIES

In the opposite case, when the cost is lower than the fair value, the respective difference is credited to the financial results of
the acquisition year. Minority interests are displayed at the proportion of the minority at the fair value of the assets and
liabilities at which they have been recognized.
Subsidiaries’ acquisitions are recognized under the purchase method. The financial results of subsidiaries, either acquired or sold
during the fiscal year, are included in the respective consolidated statements respectively from their acquisition date or the date
of their disposal.
When deemed necessary, subsidiaries’ financial statements are restated in order for the data to be homogeneous and
comparable with the respective data of the remaining companies of the Group. During the consolidation, all the intra-group
transactions and balances as well as losses and gains between the companies of the Group, are eliminated.
In the Company’s financial statements participations in subsidiaries and affiliates are displayed at their cost, less any impairment
of their value. The company examines - on an annual basis or whenever there is any indication of impairment - the accounting
value of the aforementioned participations compared to the retrieval value on the basis of the higher value between fair value
less cost to sell and the value in use.
Investments in associates
Associates are those companies on which the Group exercises significant influence but that do not meet the requirements to be
treated as subsidiaries. The consolidated financial statements include the Group's share in the profits and losses of the
associates, based on the equity consolidation method from the date that the Group obtains significant influence until the date
that it ceases to exist such influence. When the Group's share in the losses of an associate exceeds the displayed book value of
the investment, the carrying value of the investment is reduced to nil and the recognition of further losses stops, unless the
Group has undertaken liabilities or contingent liabilities of the associate, beyond that arising from its shareholder state. The
results stemming from transactions between the companies of the Group and the associates are eliminated to the extent of the
investment of the Group in the associates.
In the separate financial statements of the Company, associates are carried at cost and are subject to impairment test annually
or in interim periods, when there are serious indications of impairment.
Goodwill
Goodwill, arising from the acquisition of a subsidiary or a jointly controlled entity or other business activity, represents the
difference between the acquisition cost and the participation of the Company in the net fair value of the identified assets,
liabilities and contingent liabilities of the subsidiary or that of the jointly controlled entity or other business activity recognized at
the date of acquisition.
Goodwill is initially recognized as an asset at cost and is subsequently measured at cost less any accumulated impairment losses.
For the purpose of impairment test, goodwill is allocated to every cash-generating unit of the company. Cash-generating units,
to which goodwill has been allocated, are aurally tested for impairment, or more frequently when there is an indication that the
unit may be impaired. If the recoverable amount of the cash-generating unit is less than the carrying amount of the unit, the
impairment loss is allocated first to reduce the carrying amount of any goodwill allocated to the unit and then to the other assets
of the unit proportional based on the carrying amount of the unit’s assets. An impairment loss recognized for goodwill is not
reversed in a subsequent period.
During the disposal of a subsidiary or a jointly controlled entity or other business activity the defined amount of goodwill is
included in the determination of the profit or loss that stems from disposal.
The Company’s policy for goodwill arising on the acquisition of an associate is described in the section ‘Investments in associates’
above.
Revenue recognition
The Group has the following major sources of revenue:
- Revenue from water supply and related services
- Revenue from sewerage and related services
- Revenue from electricity sale
- Revenue from sales of inventory

Also, the Company enters into construction contracts with customers. However, there were no construction contracts during the
current interim period and the comparative period.
Revenue is measured based on the consideration specified in a contract with a customer and excludes amounts collected on
behalf of third parties. The Group recognizes revenue when it transfers control of a product or service to a customer.
The Group does not enter into any contracts where the period between the transfer of the promised goods or services to the
customer and the payment by the customer exceeds one year. As a consequence, the Group does not adjust any of the
transaction prices for the time value of money.
Revenue from water supply and sewerage services and related services
Water supply and sewerage services are the major sources of revenue for the Company and the Group and represent two
separate distinct performance obligations. Revenue for each of the above-mentioned two performance obligations is recognized
over time, since the customer simultaneously receives and consumes the benefits arising from both the water consumption and
the utilization of the sewerage network. Revenue is measured based on the quantities of water consumed and the effective price
lists. The Company invoices the customers for the water supply and sewerage services mainly on a quarterly basis based on
relevant measurements. In cases where the Company has not performed the relevant measurements for consumed quantities
up to the end of the reporting period, it conducts estimates on the consumption based on historical data and recognizes the
relevant revenue. The Company recognizes a contractual asset for revenue accrued and not yet invoiced to customers. A
receivable is recognized by the Company when the relevant invoice is issued, as this represents the point in time at which the
right to consideration becomes unconditional, as only the passage of time is required before payment is due. The usual credit
period for the settlement of accounts is approximately 30 days from the date of issuance of the relevant document. Also, the
Company adjusts the revenue recognized at each reporting period based on estimates for expected refunds to customers for
various reasons. The relevant estimates are supported by historical data and the Company recognizes a corresponding refund
liability.
The Company’s customers are required to participate in the network connection cost (meters, distribution network, connections
pipes). In particular, customers are charged for water supply and sewerage services with one-off upfront fees that relate to the
construction of the connection network and the equipment (including any upgrades and extensions). Based on the Company's
assessment, the connection of each house to the water and sewerage network represents a distinct performance obligation
since the connection has a stand-alone value for the customer. In other words, a property will be more valuable if it possesses a
connection to the water and sewerage network than without the connection. Revenue from these one-off fees is recognized at a
point in time, and particularly at the time when the connection is established.
The Company recognizes a contractual liability when it receives advance payments from customers in exchange for goods or
services to be transferred to them.
Revenue from electricity sale
Sale of electric power represents a single performance obligation and revenue is recognized over time by measuring the progress
towards complete satisfaction of the performance obligation based on the kWh sold and the effective price lists. The Company
invoices monthly for the sale of electric power and recognizes a relevant receivable upon invoicing.
Revenue from sales of inventory
Sales of inventory relate to sales of scrap to customers. Relevant revenue is recognized at a point in time, when control of the
goods has been transferred to the customers. Since the terms in each contract may vary from each other, the Company assesses
on a contract by contract basis when control of the goods is transferred to the customers based on the criteria provided by IFRS
15, paragraph 38 (immediate right to payment, legal title, physical possession, significant risks and rewards of asset ownership,
acceptance of goods by the customer).

Leases
Accounting policies according to IFRS 16 since 1st January 2019
The Group as a lessee
The Group assesses whether a contact is or contains a lease, at inception of a contract. Accordingly, it recognizes a right-of-use
asset and a corresponding lease liability with respect to all lease agreements in which it is the lessee, except for short-term
leases (defined as leases with a lease term of 12 months or less) and leases of low value assets. For these leases, the Group
recognizes the lease payments as an operating expense on a straight-line basis over the term of the lease. “Silent renewed”
contracts of indefinite life are not enforceable, meaning that no relevant rights and liabilities emanate from the above contracts.
The Group recognizes the lease payments associated with those contracts as operating expenses in the income statement.
The lease liability is initially measured at the present value of the lease payments that have not been paid at the commencement
date, which are being discounted by using the rate implicit in the leases. If this rate cannot be readily determined, the Group
uses its incremental borrowing rate. Lease payments included in the measurement of the lease liability comprise:
• fixed lease payments (including in-substance fixed payments), less any lease incentives;
• variable lease payments that depend on an index or rate, initially measured using the index or rate at the commencement date
of the lease period;
• the amount expected to be payable by the lessee under the residual value guarantees;
• the exercise price of purchase options, if the lessee is reasonably certain to exercise the options; and
• payments of penalties for terminating the lease, if the lease term reflects the exercise of an option to terminate the lease.
The lease liability is subsequently measured by increasing the carrying amount to reflect interest on the lease liability (using the
effective interest method) and by reducing the carrying amount to reflect the lease payments made. The Group remeasures the
lease liability (and makes a corresponding adjustment to the related right-of-use asset) whenever:
• the lease term has changed or there is a change in the assessment of exercise of a purchase option, in which case the lease
liability is remeasured by discounting the revised lease payments using a revised discount rate.
• the lease payments change due to changes in an index or rate or a change in expected payment under a guaranteed residual
value, in which cases the lease liability is measured by discounting the revised lease payments using the initial discount rate.
• a lease contract is modified and the lease modification is not accounted for as a separate lease, in which case, the lease liability
is remeasured by discounting the revised lease payments using a revised discount rate.
The lease liability is presented as a separate line in the consolidated statement of financial position.
The right-of-use asset comprises the initial measurement of the corresponding lease liability, lease payments made at or before
the commencement day and any initial direct costs. They are subsequently measured at cost less accumulated depreciation and
impairment losses. The Group applies IAS 36 to determine whether a right-of-use asset is impaired.
Whenever the Group incurs an obligation for costs to dismantle and remove a leased asset, restore the site on which it is located
or restore the underlying asset to the condition required by the terms and conditions of the lease, a provision is recognized and
measured under IAS 37. These costs are included in the related right-of-use asset. The Group did not incur any such costs during
the periods presented in the annual financial statements.
Right-of-use assets are depreciated over the shorter period between the lease term and useful life of the underlying asset. If a
lease ownership transfer of the underlying asset or the cost of the right-of-use asset reflects that the Group expects to exercise a
purchase option, then the related right-of-use asset is depreciated over the useful life of the underlying asset. The depreciation
starts at the lease commencement date.
The right-of-use assets are presented as a separate line in the consolidated statement of financial position.
Variable leases that do not depend on an index or rate are not included in the measurement of the lease liability and the right-
of-use asset. The related payments are recognized as an expense in the period in which the event or condition that triggers
those payments occur.
As permitted by IFRS 16, the Group applied the practical expedient according to which a lessee is not required to separate non-
lease components, and as such, it accounts for any lease and associated non-lease components as a single arrangement.

Fiscal Year 01.01.2021 – 31.12.2021

The Group as a lessor
Leases, in which the Group is a lessor, are classified as finance or operating leases. Whenever the terms of the lease transfer
substantially all the risks and rewards of ownership to the lessee, the contract is classified as a finance lease. All other leases are
classified as operating leases.
When the Group is an intermediate lessor, it accounts for the head lease and the sublease as two separate contracts. The
sublease is classified as a finance or operating lease by reference to the right-of-use asset arising from the head lease.
Rental income from operating leases is recognized on a straight-line basis over the term of the relevant lease. Initial direct costs
incurred in negotiating and arranging an operating lease are added to the carrying amount of the leased asset and recognized on
a straight-line basis over the lease term.
Amounts due from lessees under finance leases are recognized as receivables at the amount of the Group’s net investment in
the leases. Finance lease income is allocated to reporting periods so as to reflect a constant periodic rate of return on the
Group’s net investment outstanding in respect of the leases.
When a contract includes lease and non-lease components, the Group applies IFRS 15 to allocate the consideration under the
contract to each component
Foreign currencies
The financial statements of the Company are presented in the currency of the economic environment, in which the entity
operates (its functional currency), which is Euro. During the preparation of the Company’s financial statements, transactions in
currencies other than the entity’s functional currency (foreign currencies) are recorded at the rates of exchange prevailing at the
dates of the transactions. On every financial statements reporting date, monetary items denominated in foreign currencies are
retranslated at the rates prevailing on the financial statements reporting date. Non-monetary items which are estimated at fair
value and denominated in foreign currencies are retranslated at the rates prevailing at the date when the fair value was
determined. Non-monetary items, measured in terms of historical cost in a foreign currency, are not retranslated.
Exchange differences are recognized in the financial result of the period in which they arise except for:
• exchange differences, related to assets under construction for future use in the production, which are included in the cost of
those assets and they are regarded as an adjustment to the interest costs on foreign currency borrowings;
• exchange differences in hedging transactions of certain foreign currency risks and
• exchange differences on monetary items receivable from or payable to a foreign operation for which settlement is neither
planned nor likely to occur, which form part of the net investment in a foreign operation, and which are recognized in the
foreign currency translation reserve and recognized in profit or loss on disposal of the net investment.
Goodwill and fair value adjustments arising on the acquisition of a foreign operation are treated as assets and liabilities of the
foreign operation and translated at the closing rate.
Borrowing costs
The borrowing costs burden the financial results of the fiscal year during which they are incurred.
Subsidies
Subsidies are not recognized until there is reasonable assurance that the Company will comply with the clauses that govern them
and that the subsidy will be received.
State subsidies, whose primary condition is the purchase or the construction, or by any other way the acquisition of non-current
assets, are recognized as deferred income in the balance sheet and transferred to the operating result on a systematicand
rational basis during the useful life of the related asset.
Other subsidies are recorded on a systematic basis in the income of the respective periods, during which matching of these
subsidies with the respective costs has to be made. State subsidies, received as compensation for expenses or losses which have
already incurred or for the purpose of providing immediate financial support to the Company with no future related costs, are
recognized in the income statement for the period, during which they become receivable.

Fiscal Year 01.01.2021 – 31.12.2021
201
The Company receives subsidies from the European Union (E.U.) the Greek State and the Organization of Local Government for
financing of specific projects. Furthermore EYDAP’s customers are required to participate in the initial network connection cost
(supply, distribution network, connections pipes, etc.) or in the upgrade/expansion of the Company’s networks. Subsidies and
customers’ contributions are deferred and amortized into income, over the period necessary to match them with the related
cost, they are provided to compensate, at the amortization rate equal to the depreciation rate of the respective assets. The
aforementioned income is presented as a subtraction from the depreciation expense in the financial statements.
Retirement benefit costs
Contributions to defined staff contribution plans are recognized as an expense when employees have provided services entitling
them to the contributions.
Regarding defined benefit retirement plans, the cost of providing benefits is determined using the Projected Unit Credit Method,
with actuarial valuation studies being carried out on each financial position statement’s date. Actuarial gains or losses are
directly recognized in the total comprehensive income for the period during which they occur, and are not transferred to the
income statement of a following period. Prior service cost is recognized immediately to the extent that the benefits are already
vested, otherwise are amortized on a straight-line basis over the average period until the benefits become vested.
The retirement benefit obligation recognized in the statement of financial position at the time of the indemnity represents the
present value of the defined benefit obligation after taking into account the adjustments for the unrecognized actuarial gains
and losses and unrecognized past work experience cost reduced by the fair value of scheme’s assets.
Any asset resulting from this calculation is limited to unrecognized actuarial losses and past working experience cost, plus the
present value of available refunds and reductions in future contributions to the plan.
Taxation
Income tax expense represents the sum of the current tax payable and the deferred tax.
Current tax
The current tax payable is based on taxable profit for the year. Taxable profit differs from profit as reported in the income
statement because it excludes items of income or expense that are taxable or deductible in other years and in addition it further
excludes items that are will never be taxed or exempted. The Company’s liability for the current tax is calculated using the
effective tax rates or those effective on the financial statements reporting date.
Deferred tax
Deferred tax is recognized on differences between the carrying amounts of assets and liabilities of the financial statements and
the corresponding tax bases, used for calculating taxable profit. Deferred tax is recorded by applying the balance sheet liability
method. Liabilities from deferred tax are generally recognized for all the taxable temporary differences and deferred tax assets
are generally recognized for all deductible temporary differences to the extent that it is probable that taxable profits will be
available against which those deductible temporary differences can be utilized. Such assets and liabilities are not recognized if
the temporary difference arises from goodwill or from the initial recognition (other than in a business combination) of other
assets and liabilities in a transaction that does not affects neither the taxable profit nor the accounting profit.
Deferred tax liabilities are recognized for all the taxable temporary differences associated which arise from investments in
subsidiaries and associates, and participations in joint ventures, with the exception of the cases where the Company is able to
control the reversal of the temporary difference and it is probable that the temporary difference will not be reversed in the
foreseeable future. Deferred tax assets arising from deductible temporary differences associated with such investments and
participations are only recognized to the extent that it is probable that there will be sufficient taxable profits against which they
could be utilized the benefits of the temporary differences and they are expected to be reversed in the foreseeable future.
The carrying amount of deferred tax assets is reviewed at each balance sheet date and is been reduced to the extent that it is no
longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered.
Deferred tax assets and liabilities are measured according to the tax rates that are expected to be effective in the period at
which the asset will be liquidized or the liability will be settled, based on effective tax rates or are effective by the balance sheet

Fiscal Year 01.01.2021 – 31.12.2021
202
date. The measurement of deferred tax liabilities and assets reflects the tax results that will follow based on the way that the
Company expects, at the reporting date, to recover or settle the carrying amount of its assets and liabilities.
Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current
tax liabilities and when they are related to income taxes levied by the same taxation authority and furthermore the Company
intends to settle its current tax assets and liabilities on a net basis.
Current and deferred tax for the period
Current and deferred taxes are recognized as an expense or income in the financial results, except when they are related to
items credited or debited directly to equity, case where the tax is also recognized directly in equity, or where they arise from the
initial recognition of a business combination. In the case of a business combination, the tax effect is taken into account in
calculating goodwill or in determining the excess between the acquirer’s interest in the net fair value of the acquired business
identifiable assets, liabilities and contingent liabilities over cost of the company.
Property, plant and equipment
Land and buildings held for use in the production or sale of goods or services, or for administrative purposes, are displayed on
the financial statement report at their acquisition cost less any subsequent accumulated depreciation and subsequent
accumulated impairment losses. Properties under construction for production, rental or administrative purposes, or for
purposes not yet determined, are carried at cost, less any recognized impairment loss. Cost includes the compensation of
professionals.
Depreciation of these assets, on the same basis as other property assets, commences when the assets are ready for their
intended use. Land owned by the Company is not depreciated.
The water supply and sewerage networks as well as the antipollution projects, waste processing centers, fixtures and equipment
are stated at cost less accumulated depreciation and any accumulated impairment losses. Depreciation is charged against the
results so as to decrease the cost or the value of the assets, with the exception of the land and properties under construction,
over their estimated useful lives, using the straight-line method. The estimated useful lives, residual values and depreciation
method are reviewed at end of each year, with the effect of any changes on the estimates to be calculated on a prospective
basis.
Assets held under finance leases are depreciated over their expected useful lives on the same basis as the owned assets or,
based on the term of the relevant lease term in case it is shorter.
The gain or loss arising from the disposal or the retirement of a property, plant and equipment item is determined as the
difference between the sales proceeds and the net book value of the asset and it is recognized in the income statement.
Intangible Assets
Intangible assets acquired separately
Intangible assets acquired separately are reported at cost less accumulated amortization and accumulated impairment losses.
Amortization is charged on a straight-line basis over their estimated useful lives of the tangible assets. The estimated useful life
and the amortization method are reviewed at the end of each annual reporting period, with the effect of any changes in
estimates being accounted on a future basis.
Internally-generated intangible assets – research and development expenses
Expenditure on research activities is recognized as an expense in the period in which it incurs.
An internally-generated intangible asset arising from development (or from the development phase of an internal project) is
recognized if, and only if, all of the following can be proven:
• the technical feasibility of completing the intangible asset so that it will be available for use or sale;
• the intention to complete the intangible asset and use or sell it;
• the ability to use or sell the intangible asset
• the intangible asset to be able to generate probable future economic benefits.
• the availability of adequate technical, financial and other resources for the completion of the development and the utilization
or sale of the intangible asset and

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
203
• the ability to measure reliably the expenditure attributable to the intangible asset during its development.
The amount initially recognized for internally-generated intangible assets is the sum of the expenditure which arises from the
date when the intangible asset first meets the recognition of the criteria listed above. Where it is not possible to recognize
internally-generated intangible asset, development expenditure is charged to the profit and loss statement in the period in
which it incurs.
Subsequent to the initial recognition, internally-generated intangible assets are reported at cost less accumulated amortization
and accumulated impairment losses, on the same basis as intangible assets acquired separately.
Intangible assets acquired in a business combination
Intangible assets acquired in a business combination are identified and recognized separately from goodwill when they meet the
definition of an intangible asset and their fair values can be measured reliably. The cost of such intangible assets is their fair
value as at the acquisition date.
Subsequent to initial recognition, intangible assets acquired in a business combination are carries at cost less accumulated
amortization and accumulated impairment losses, on the same basis as intangible assets acquired separately.
Impairment of tangible and intangible assets excluding goodwill
On every financial statements reporting date, the Company reviews the carrying amounts of its tangible and intangible assets to
determine whether there is any indication that those assets have suffered an impairment loss. If any such indication exists, the
recoverable amount of the asset is estimated in order to determine the extent of the impairment loss (if any). When it is not
possible to estimate the recoverable amount of an individual asset, the Company estimates the recoverable amount of the cash
flow-generating unit, to which the asset belongs.
When a reasonable and consistent basis of allocation can be identified, corporate assets can also be allocated to separate cash
flow-generating units, or otherwise they are allocated to the smaller group of cash flow-generating units for which a reasonable
and consistent allocation basis can be identified.
Intangible assets with indefinite useful lives and intangible assets not yet available for use are tested for impairment annually,
and whenever there is an indication that the asset may be impaired.
Recoverable amount is the higher between the fair value deducted by the sale costs and the value in use. In assessing value in
use (of the asset), the estimated future cash flows are discounted to their present value using a pre-tax discount rate that
reflects the current market assessments of the time value of money and the risks related to the asset.
If the recoverable amount of an asset (or cash flow-generating unit) is estimated to be less than its carrying amount, the carrying
amount of the asset (cash flow-generating unit) is reduced to its recoverable amount. An impairment loss is recognized
immediately in the profit and loss account.
When an impairment loss subsequently is reversed, the carrying amount of the asset (cash flow-generating unit) is increased to
the revised estimate of its recoverable amount, so as the increased carrying amount does not exceed the carrying amount that
would have been determined if there had not been recognized any impairment loss for the asset (or a cash flow-generating unit)
in prior years. A reversal of an impairment loss is directly recognized in the income statement.
Inventories
Inventories are recorded at the lower value between acquisition cost and net liquidation value. The acquisition cost is calculated
via the weighted average cost method. The cost incorporates all respective materials and whenever is required it also includes
direct labor costs and the respective general industrial expenses incurred for the processing of inventories to their final
condition. The net realizable value represents the estimated selling price less the estimated costs necessary for the completion
of the sale.
Provisions
Provisions are recognized when the Company has a present obligation (legal or constructive) as a result of a past event, it is
probable that the Company will be required to settle the obligation, and a reliable estimate can be made of the amount of the
obligation.

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
204
The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation on the
financial statements reporting date, taking into account the risks and uncertainties surrounding the obligation. Where a
provision is measured using the cash flows estimated to settle the present obligation, its carrying amount is the present value of
those cash flows.
When part or all of the economic benefits required to settle a provision are expected to be recovered from a third party, the
receivable is recognized as an asset when it is practically certain that reimbursement will be received and the amount of the
receivable can be measured reliably.
Onerous contracts
Present obligations arising under onerous contracts are recognized and measured as a provision. An onerous contract is
considered to occur where the Company has a contract under which the unavoidable costs of meeting the obligations under the
contract exceed the economic benefits expected to be received under it.
Restructuring
A provision for costs of restructuring is recognized when the Company has developed a detailed formal plan for the restructuring
and has raised a valid expectation, to those been affected, that it will carry out the restructuring by starting the implementation
of the plan or announcing its main features to those been affected by it. The measurement of a restructuring provision includes
only the direct expenditures arising from the restructuring, which necessarily stem from the restructuring and simultaneously
are not associated with the ongoing activities of the entity..
Warranties
Provisions for warranty costs are recognized at the date of the sale of the relevant products, according to the Management’s
best estimates for the expenditure required to settle the Company’s obligation.
Financial instruments
The Group and the Company have selected to apply the limited exemption in IFRS 9 paragraph 7.2.15 relating to the transition
for classification, measurement and impairment of the financial assets, and accordingly have not restated the items in the
comparative periods in the initial application. As a consequence, any adjustments to the book value of the financial assets and
the provisions for impairment at the financial position were recognized retrospectively with the cumulative effect from the initial
adoption adjusting the opening balance of retained earnings on 1st January 2018, meaning that not restatement occurred in the
items of the equity in the comparative period.
Investments in financial assets are classified as either liability or equity investments in equity with reference to the requirements
for the issuer in IAS 32 “Financial Instruments”.
(a) Impairment of Financial Assets
The categories of financial assets that are subject to IFRS 9 new expected credit loss model are the following:
• Trade and Other Receivables
• Cash and Cash Equivalents.
The Group and the Company revised their impairment measurement methodology under IFRS 9 for each of these assets
categories.
Impairment
The Group and the Company apply the simplified approach for the estimation of the expected future credit losses in relation to
the “Trade Receivables” as it is required by IFRS 9, paragraph 5.5.15. The Group recognizes the provision for the expected credit
losses during the initial recognition with regard to the item “Trade Receivables”, classified and measured at amortized cost.
In the context of the requirements set by the IFRS 9 regarding the financial asset “Trade Receivables”, the Group has adopted
the simplified approach according to which it recognizes and classifies the financial asset “Trade Receivables” either in stage 2 or
in stage 3 based on the days of delay in the payment of the accounts as follows:

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
205
• Stage 2: 0-89 days of delay from the day of payment stated in the invoice. In stage 2, trade receivables are not impaired.
• Stage 3: 90 or more days of delay. Stage 3 includes trade receivables for whom a default event has occurred (they are
impaired).
For stages 2 and 3, the Company forms the Expected Credit Losses on the basis of risk parameters which are calculated according
to the historic data. The risk parameters are the estimated probability of default, the percentage of loss on the amount due
given that the customer has defaulted in the payment of this amount due, and the outstanding amount which the Company is
exposed to in case of the customer’s default.
As general rule, the assessment of the classification in stages is performed in each reporting period.
The Group recognizes the provision for expected credit losses during the initial recognition of the financial asset “Trade
Receivables”, classified and measured at the amortized cost.
Investments and Other Financial Assets
Classification
From the transition date of 1st January 2018, the Group and the Company classified their financial assets in the following
categories:
• Measured at fair value (either through other comprehensive income or through profit or loss),
• Measured at amortized cost
The classification depends on the entity’s business model for managing the financial assets and the contractual terms of the cash
flows.
For assets measured at fair value, gains and losses will either be recorded in profit or loss or in other comprehensive income. For
investments in equity instruments not held for sale, it will depend on whether the company has made an irrevocable election at
the time of initial recognition to account for the equity investment at fair value through other comprehensive income (FVOCI).
Measurement
At initial recognition, the Group and the Company measure a financial asset at its fair value plus transaction costs that are
directly attributable to the acquisition of the financial asset, provided that the Group and the Company do not recognize this
asset in the income statement, but in other comprehensive income. In case the asset is recognized in the income statement,
potential costs are expensed.
Investments in equity instruments
The investments available for sale were recognized at fair value through other comprehensive income, in particular::
Listed equity instruments have been reclassified at the transition date 1 January 2018 from the item "Investments Available for
Sale" to the item “Financial Instruments at Fair Value through Other Comprehensive Income”. This reclassification has been
made irrevocably for both the Group and the Company. In compliance with IFRS 9, the Group and the Company consider that the
cost of these equity instruments represents an appropriate estimation of their fair value.
The equity investments are measured at fair value. Where the Group's and the Company’s management have elected to present
fair value gains and losses on equity investments in other comprehensive income (OCI), there is no subsequent reclassification of
fair value gains and losses into profit or loss following the de-recognition of the investment. Dividends from such investments
continue to be recognized in profit or loss as other income when the Group's and the Company’s right to receive payments is
established.
Changes in the fair value of financial assets through profit and loss are recognized in other gains/(losses) in the statement of
profit or loss as applicable. Impairment losses (and reversal of impairment losses) on equity investments measured at FVOCI are
not reported separately from other changes in fair value.
Cash and cash equivalents

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
206
Cash and cash equivalents comprise of cash on hand and deposits, and other short-term highly liquid investments that are easily
converted to a known amount of cash and subject to an insignificant risk of changes in their value.
Operating segments
The key operations of the Company (water supply, sewerage services and others) are not subject to different risks and returns.
As a result the company did not present the disclosures with respect to the operating segments. It is clarified that the Company
operates in one geographical segment (Attiki Metropolitan area). The policy and the decision making is common for the
operating segments of the Company.
4. KEY ACCOUNTING TREATMENTS AND SIGNIFICANT SOURCES OF UNCERTAINTY
During the preparation of the financial statements in accordance with the accounting policies of the Group, as presented in Note
3, it is essential for the management to proceed with judgments, estimations and assumptions with regard to the book value of
the assets and the liabilities, which are not obvious from other sources of information.
The estimates and the relevant assumptions, are based on the past empirical evidence, estimates of specialized external advisors
as well as other related factors. The actual results may differ from these estimates.
The estimates and the subjective assumptions are reviewed on on-going basis. The revisions of accounting estimates are
recognized in the period of occurrence, if they affect only the particular period or in future periods as well.
The accounting judgments which have been made by the management during the application of the Group’s accounting policies
and which significantly affect the financial statements of the Company and the Group are the following:
1. Provision for contingent doubtful customer receivables (retail customers, Greek State, local authorities - OTA).
2. Provisions concerning four defined benefit plans for the personnel.
4. Provisions for pending judicial cases relating to labor issues.
5. Term of the lease
It is common practice in the Greek rental market of commercial real estate, for the tenant to continue to use the property even
after the expiration date of the lease agreement. The above-mentioned so-called "silently renewed" lease agreements become
indefinite after their expiration date and continue to create enforceable rights and obligations, provided that none of the
counterparties proceeds to terminate them. According to the Hellenic Civil Code, each of the counterparties has the right to
terminate the lease without the imposition of a penalty immediately after the end of the short notice period as defined in the
above code. Since both the lessee and the lessor have the right to terminate the lease without obtaining the relevant
permission of the counterparty and without requiring the payment of any amount as compensation, the Group assessed that
the "silently renewed" lease agreements do not create obligations after the expiration of their contractual date and therefore
do not meet the definition of the lease contract based on IFRS 16. Consequently, the Group concluded that the duration of the
lease of "silently renewed" contracts is their initial contractual duration. The Group therefore recognizes the rents associated
with these leases as operating expenses in the Income Statement.
6. Incremental Borrowing Rate
To determine the incremental borrowing rate, the Group used the yield curve of Greek government bonds as a reference
interest rate, which was adjusted to the Group's credit spread. In order to incorporate in the above incremental borrowing rate
the fact that the loan is secured, the difference in the yield spread between the covered bonds of the Greek Systemic Banks and
the bonds of the Greek State was utilized.
Furthermore the management annually reviews, in terms of assumptions and estimations, the following:
1. Useful life and recoverable amount of the depreciated tangible assets and the amortized intangible assets.
2. Income tax which incorporates the provision for the current income tax and the provision for additional taxes and incremental
charges for tax unaudited years.
3. Recoverability of deferred tax receivables.

5. REVENUES
Paragraph 4 of Article One Hundred and Fourteen (114) of Law 4812/2021 (A’110) provided the terms under which EYDAP is
obliged to maintain and operate the External Water Supply System (EYS) of the major Capital area for a three-year period, which
may be extended by agreement of the parties. Following the contract dated 02.02.2022 between the Greek State, EYDAP Fixed
Assets (EPEYDAP) and EYDAP SA (Company) with a term of validity from 01.01.2021 to 31.12.2023 and the possibility of
extension for an additional period of six (6) months, a memorandum of understanding was signed on 27.04.2022 which clarified
Article 10 of the Contract of L.4812 / 2021 ( Exclusive Right Contract) as well as Article 9 of the contract under which EYDAP was
assigned the operation and maintenance of the External Water Supply System.
Article 9 (Contractor's Fee) of the maintenance and operation contract defines that for the regular operation and maintenance
services provided by EYDAP for the period of three years with the right of extension for an additional six months, a fixed annual
flat-rate fee of Euro 25,000 k is agreed. For 2021 the consideration for the provision of maintenance and operation services of
the External Water Supply System is included in turnover.
It is clarified that throughout the three-year period of validity of the present and, in case of its extension, for six additional
months, EPEYDAP will not pay in cash to EYDAP this fixed fee, the receivable for which is reconciled with the corresponding
requirement of EPEYDAP from granting the intangible exclusive right.
The Company’s revenues are analyzed as follows:

The change in turnover is mainly due to:
• revenue from the provision of operation and maintenance services amounting to Euro 25 million.
• increase in consumption by 1.4%, i.e. an increase in water and sewerage revenues by approximately Euro 5 million, and
• increase in revenue from water supply and sewerage works of approximately Euro 1 million.
• decrease in revenue from sales of electricity of Euro 0.7 million.
Financial income dropped by Euro 0.1 million (Note 9).
The Group segregates revenue from contracts with customers on the basis of the service transfer time, as the management
believes that this demonstrates better that the nature, quantity, timing and uncertainty of the Group's income and cash flows
are affected by economic factors.

Following the J.M.D. no. 352462 / 14.12.2021 (Government Gazette No. Sheet 5830) of the Ministries of Finance, Development
& Investment, Environment & Energy, Infrastructure & Transport, in which both the EYDAP’s post due debts to the Greek State
were definitively settled for the consideration of the supply of raw material for the period 12.10.2012 -31.12.2020 as well as the
operating expenses of EYDAP for the management, maintenance and supervision of sound operation of EYS during the period
from 01.10.2013 until 31.12.2020. On 28.12.2021 the Company applied amended income tax returns for a total of six (6) tax
years and specifically for the years 2015 - 2020.
During the electronic liquidation of the above tax returns for the years 2015-2020 and based on the newly formed taxable results
of the Company, a credit balance to be returned to the Company amounting to Euro 39.5 million arose, as recorded in the item
"Other Receivables". From this amount, an amount of Euro 3,667 k relates to the return of additional advance paid by the
company, since a higher income tax had been calculated for the period 2015-2020.
The financial statements include provisions for potential tax differences totaling € 2.4 million.
NISON EYDAP DEVELOPMENT SA has not been audited for tax purposes from the fiscal year 2011 and onwards and no relevant
provision has been made due to its limited business transactions.
12. EARNINGS PER SHARE
The basic earnings per share are calculated by dividing the net profit of the period attributable to ordinary shareholders with the
weighted average number of ordinary shares in issue during the period. Profits are defined as profits/losses from continuing
operations of the Group. It is noted that in the current year, as well as in the previous one, there were no discontinued
operations. There were no convertible bonds or other potentially dilutive convertible securities during the periods reported in
the accompanying financial statements, so there is no calculation of any diluted earnings per share.
An entity presents basic and diluted earnings per share, even if the disclosed amounts are negative (e.g. loss per share).

On 02/02/2022, pursuant to paragraphs 1, 2 and 4 of Article 114 of Law 4812/2021, the following contracts were signed
between the Greek State, the legal entity under public law EPEYDAP and EYDAP SA:
(1) the relevant contract under Law 4812/2021 (Exclusive Right Contract) following which, among other things, against
consideration the State - EPEYDAP grants the intangible and special right, provided by the Law, of the exclusive supply of raw
water to EYDAP and agrees on the annual supply of raw water for twenty years effective from 1.1.2021 to 31.12.2040, as

As an implementation of the above legislative provision, under Article 10 of the Exclusive Right Contract, against consideration,
EYDAP SA receives the special intangible right of exclusive supply of Raw Water throughout the period provided by Law and in
the contract term (1.1.21 - 31.12.2040) and its Consideration (Raw Water) is agreed, determined on the basis of a price per cubic
meter that is valid for each reporting year according to a table included in the aforementioned Contract.
On 27.04.2022 a memorandum of understanding was signed between the Company and EPEYDAP, and the consideration paid
for the intangible right of exclusive supply of raw water amounting to Euro 87,500 k was determined. It is to be noted that
EPEYDAP will not collect the amount of intangible right in cash as its claim will be offset against the corresponding claim of the
Company due to the provided network maintenance service during three and a half years, according to the respective contract
for maintenance and operation of the external water system.
15. TANGIBLE ASSETS
The Company, applying the provisions of IFRS 1 “First-time adoption of IFRS”, used the exception concerning recording and
valuation of property assets during the compilation of the Transitional Balance Sheet to the IFRS on 1 January 2004. In this
context, the Company considered the adjusted value of its property assets as deemed (implied) cost for the purposes of the
compilation of the Transitional Balance Sheet to the IFRS on 1 January 2004.
Specifically for the transition to IFRS, the Company recorded the self-utilized property assets at fair values based on studies
performed by independent valuators. These fair values constituted the deemed cost for the compilation of the Balance Sheet.

The Group mainly leases land & buildings, in order to serve its administrative and operational needs. Lease terms are negotiated
on an individual basis and contain a wide range of different terms and conditions. The majority of those lease contracts contain
apart from the standard fixed rent payments and additional rent payments that are mainly linked to the change in the consumer
price index (CPI). There are no lease contracts containing a variable rent payment, beyond those that depend on an index or
interest rate such as the CPI. Leases of land & buildings are typically made for a fixed period of 8-12 years.
The Group leases excavation machines and transportation means in order to cover its operational needs. The average contract
duration is 3 months. The Group recognizes the leases of these type of lease contracts as operating expenses on a straight-line
basis throughout lease period.

17. INVESTMENTS IN SUBSIDIARIES
On 18th July 2011, following the BoD decision 17241/13.05.2011, EYDAP SA established a company under the title “NISON
WATER SUPPLY AND SEWERAGE S.A.” and distinctive title “NISON EYDAP SA”, which is fully owned (100% via capital deposit of
1,210 k Euro) by EYDAP SA. With the decision of the Extraordinary General Meeting of shareholders of the societe anonyme
dated 21/09/2017, the title changed to “NISON WATER SUPPLY AND SEWERAGE S.A. DEVELOPMENT" with the distinctive title
"NISON EYDAP DEVELOPMENT SA".
“NISON EYDAP DEVELOPMENT SA” operates in the domain of water supply, sewerage, irrigation, and rain water collection in
Greece’s islands. The subsidiary has limited business activity until today.
The annual audited Financial Statements of the company “NISON EYDAP DEVELOPMENT S.A.” are available on the Internet at the
company’s website under the domain name www.eydapnison.gr.
18. FINANCIAL ASSETS AT FAIR VALUE THROUGH OTHER COMPREHENSIVE INCOME
Financial Assets include the following:
• Investment in EYATH SA, a company listed on the Athens Exchange, which provides the company with the option to
generate income from dividends and potentially from capital gains. The company was valued at fair according to the
official price quote of the Athens Exchange on 31.12.2021 and the difference that emerged due to the change of fair
value was recorded in equity through the Statement of Total Comprehensive Income.
• Investment in Attica Bank. EYDAP SA, with the decision no. 18770/18.12.2015 of the Board of Directors approved its
participation in the share capital increase of Attica Bank Societe Anonyme, based on an amount of € 20 million. The
above decision was verified by the Extraordinary General Meeting of shareholders on 15/01/2016. The investment of
the Company in the shares of Attica Bank is considered as strategic one and therefore it has been recorded under the
category of equity participations at fair value through the other comprehensive income. With the information
prospectus on 24.04.2018, Attica Bank announced a share capital increase via the issuance and allocation of new
common shares based on preemptive rights in favor of the existing common shareholders and according to a ratio of 4
new shares for every 1 old share. EYDAP SA with the decision no. 19649/11.05.2018 of the Board of Directors approved
not to exercise any preemptive right in the share capital increase of Attica Bank. As a result, the Company’s
participation settled at 4,701,457 shares which were valued at fair based on the official price quote of the Athens
Exchange on 31.12.2021, and the balance (profit) that emerged due to the change in the fair value was recorded in
equity thorough the statements of other comprehensive income. As from September 30, 2021 the shares shrank
thorough the reverse split at a ratio of 1/60 and amounted to 78,357 shares measured at fair value according to the
official price of the Athens Stock Exchange on 31.12.2021 and the difference (loss) arising due to the change in fair value
was recorded in equity through the statement of other comprehensive income.
Following the above, the Company’s portfolio was formed as follows:

22. TRADE RECEIVABLES, CONTRACTUAL ASSETS (GROUP & COMPANY)
The balance of Trade Receivables and Contractual Assets prior to impairment due to provisions for bad debt settled at € 328.9
million approximately during the current period.
The Group and the Company applied the simplified approach for the estimation of the expected future credit losses in relation to
the “Trade Receivables” as it is required by IFRS 9, paragraph 5.5.15. The Group recognizes the provision of the expected credit
losses during the initial recognition with regard to the item “Trade Receivables” which is being classified and measured at the
amortized cost.
In the context of the requirements set by the IFRS 9 regarding the financial asset “Trade Receivables”, the Group has adopted
the simplified approach according to which it recognizes and classifies the financial asset “Trade Receivables” either in stage 2 or
in stage 3 based on the days of delay in the payment of the invoices as follows:
• Stage 2: 0-89 days of delay from the day of payment stated in the invoice. Trade receivables classified in stage 2 are not
impaired.
• Stage 3: 90 or more days of delay. Trade receivables classified in stage concern the customers ,for whom a default event has
occurred (they are impaired).
For stages 2 and 3, the Company forms the Expected Credit Losses on the basis of risk parameters which are calculated according
to the historic data. The risk parameters are the estimated probability of default, the percentage of loss on the amount due
given that the customer has defaulted in the payment of this amount due, and the outstanding amount which the Company is
exposed to in case of the customer’s default.
As a general rule, the assessment of the classification in stages is performed in every reporting period.
The provision for impairment of trade receivables is presented below as follows:

Due to the large number of customers (approximately 2.059.866 as of 31.12.2021), the credit risk for the Company is quite
limited. At the same time the contractual terms for the provision of water supply and sewerage services are such that ensure to
the greatest possible extent that the amounts invoiced will be collected from the users (customers).
The Department of Revenue & Trade Receivables Management continuously monitors the claims of the Company, either
separately or based on groups (invoice codes, customer categories) and incorporate this information into the credit risk control
procedure in order to make the respective provision.
In the context of procedures provided by the Public Revenue Collection Code (Law 356/1974), as it was amended with the law
provisions 4174/2013, 4224/2013, 4337/2015 & 4517/2018, the Company calculates the relevant interest charged on the
overdue amounts at the time of their payment.
Trade and Other Receivables
The Group and the Company apply the simplified approach to estimate the expected future credit losses of the "Trade
Receivables" in accordance with IFRS 9. In order to measure the expected credit losses, the "Trade Receivables" are classified
with, based on credit history parameters that have been computed with historical data and the payback days of the accounts.

Athens at the time, under the titles Hellenic Water Supply Company and the Sewerage Organization of Athens.
The initial share capital of the Company settled at € 130,502 k and was based on the valuation of assets and liabilities of the
merged entities according to the clauses of Law 1068/1980.
In 1992, the share capital amounted to € 1,253,507 k consisting of 213,566,232 common shares with a nominal value of € 5.87
per share. The share capital increase took place pursuant to Law 1914/1990 following a new valuation of the Company’s net
worth in view of significant number installations, which were contributed by the Greek State to the Company at the time, and
following the capitalization of liabilities towards the State.
The General Meeting held on 30 June 1998 approved an additional increase of the Company’s share capital by € 6,845 k via the
capitalization of investment subsidies that had been collected up to 31 December 1997. Following the above increase, the
Company’s share capital amounted to € 1,260,352 k consisting of 214,732,544 common shares with a nominal value of €5.87
(two k drachmas) per share.
In 1999, due to the Company’s listing on the Athens Exchange and according to Law 2744/1999, its share capital was set at €
58,694 k consisting of 100,000,000 common shares with a nominal value of € 0.59 (two hundred drachmas) per share. According
to the same Law, the remaining amount of € 1,201,658 k of the share capital was converted to a ‘’Special Non Taxable Reserve’’,
which was among others decreased by the net amount of fixed assets, which were transferred to «EYDAP Fixed Assets» at no
cost. In December 1999, 6,500,000 new ordinary shares were issued at a nominal value of € 0.59 (two hundred drachmas) per
share and were allocated through an initial public offering for the Company’s listing on the Athens Exchange.
As a result, the Company’s share capital as of December 31, 2000 had amounted to € 62,509 k consisting of 106,500,000
common shares with a nominal value of € 0.59 (two hundred drachmas) per share.
In May 2001, EYDAP decided to denominate its share capital into Euro, through the increase of the nominal value per share from
€ 0.59 to € 0.60, and the amount of € 1,391 k of the above share capital increase was transferred from the “Share Premium
Account”. Thus, the share capital of the Company was equivalent to € 63,900 k consisting of 106,500,000 common shares with a

share by €0.23, i.e. from €0.60 to €0.83. Thus, the Share Capital of the Company amounted to eighty-eight million three hundred
ninety-five thousand euro (88.395.000) divided into one hundred and six million five hundred thousand shares (106,500,000)
with a nominal value of eighty-three cents of each share (€0.83),
Β) and simultaneously the reduction of the share capital by the amount of €24,495 k and the modification of the relevant article
5 in the Company’s Articles of Association. The nominal value of the share was reduced by €0.23 accordingly, and remained at
the price of €0.60, i.e. from €0.83 to €0.60, and at the same time there was a capital return by paying cash to the shareholders in
the amount of 0.23€ per share.
Thus, the Share Capital of the Company currently amounts to sixty three million nine hundred thousand euro (63.900.000) and is
divided into one hundred and six million five hundred thousand shares (106.500.000) of a nominal value of each share sixty cents
(0.60€).

Legal reserve:
According to the Greek commercial law concerning Societe Anonymes (Article 44, L. 2190/1920), as amended by Law 4548/2018,
companies are required to transfer at least 5% of their annual net profits to a legal reserve until this reserve becomes equivalent
with the 1/3 of the paid up share capital. The particular reserve is not distributable and the purpose of its creation is to cover
future losses. On 31.12.2011, the Company covered the required by law legal reserve as percentage of its total paid up share
capital. During the year 2015, the Company arranged a reserve formed due to revaluation of shares amounting to € 660 k
approximately according to article 72 of Law 4172/2013.
Special Non-Taxable Reserve under Law 2744/99:
The Special Non-Taxable Reserve was formed with the Company’s listing on the Athens Stock Exchange (ASE) in financial year
1999, from the denomination of the Company’s share capital at the time to the euro equivalent of € 58,694 while its previous
balance was € 1,201,658.
Based on the clauses of L. 2744/99, the initial balance of the reserve:
• Was reduced with the net, non-depreciated, value of the facilities which were granted to “EYDAP Fixed Assets LEPL” at no
consideration.
• Was decreased with the various amounts of provisions which were recorded in the Company’s accounting books during
its listing on ASE.
• Was increased with the surplus value deriving from the revaluation of the installations and networks that remained in the
possession of the Company.

• And was increased with the transfer of the account “Profit/loss carried forward” which was recorded in the Balance Sheet
of 31 December 1998.
In accordance with Law 2744/99, the reserve was classified as “Special Non-Taxable Reserve”.
27. RETAINED EARNINGS
The account in the financial statements is analyzed as follows:
28. EMPLOYEE BENEFIT OBLIGATIONS (GROUP & COMPANY)
The International Financial Reporting Interpretations Committee ("IFRIC"), in May 2021, adopted the final agenda item entitled
"Attributing benefit to periods of service (IAS 19)" (the "Decision"). According to the IFRIC opinion, in the case of a compensation
policy which provides for the payment of benefits only at retirement age and the amount of the benefit increases with the years
of service up to a maximum (for example up to 16 years), the corresponding employer liability is attributed to the last working
years before retirement, taking into account the maximum period beyond which the benefit is not further increased.
This Decision affects the calculation of staff compensation provisions based on the provisions of Greek labor law (Law 2112/20,
Law 3198/55 & Law 4093/12). For this reason, following the publication of the IFRIC Decision, a Technical Committee was
established by the Scientific Board of the Institute of Certified Public Accountants of Greece (SOEL) with the participation of
actuaries in order to examine the implementation of the Decision in all compensation policies in the Greek market and to
prepare a draft of Guidelines for the preparation of actuarial studies in application of this Directive. In mid-December 2021 the
Technical Committee completed its conclusions, which were submitted for approval by the Supervisory Board of SOEL. The final
draft of the conclusions and instructions was published on 13 January 2022 (the "Instructions"). The main conclusion is that in
the Greek Market there are various benefit policies that may differ from the compensation policy considered by IFRIC for the
issuance of the Decision, as either higher benefits are granted than the minimum amount described in the law, or
compensations are given for other reasons of leaving the service except regular retirement.
Specifically, the Technical Committee studied the application of the Decision in cases of employers where there is a legal or
presumptive obligation to award compensation in case of voluntary retirement after 15 years of service, in accordance with the
provisions of current legislation. According to paragraph 2 of the Directives, in cases of political compensation provided for the
payment of a benefit earlier than normal retirement, the application of the Decision should also take into account the period of
securing the benefit.
According to the 02/07/91 Special Collective Employment Agreement ("ESSE") of EYDAP, the employees of the company are
entitled to a lump sum compensation determined by the years of service and the final monthly salary. The above one-time
benefit is maximized in the 34 years of service where compensation equal to 30 salaries is paid. The employees secure the

benefit either in case of full retirement from the Social Security or by completing 20 years of service in EYDAP and the 50th /
45th year of age for men / women (chapter B, par. 2 of the ESS). The benefit is also paid in cases of disability and death.
EYDAP Lump Sum Provision Distribution Method
The aforementioned description of the EYDAP lump sum benefit is not in line with the benefit policy referred to in the IFRIC
Decision, because the benefit is secured earlier than the retirement age under the condition of 20 years of service and age 50/45
for men / women. Following the Instructions of the Technical Committee, par. 2, for the implementation of the Decision, both
the specific provision of the ESSE and the projected period of maximization of the provision (34 years of service) should be taken
into account.
Therefore, the retirement benefit is attributed during the first 34 working years from the date of employment at EYDAP. With
regard to the extraordinary events of disability and death, according to par. 4.4.7 of the Instructions, the benefit paid in these
cases is attributed according to the case of leaving the service, described above, ie during the first 34 working years from the
date of recruitment. The proposed method of distribution is consistent with that followed in the actuarial studies of previous
years. Therefore, there is no change in accounting policy from the implementation of the IFRIC Decision. The Company and the
Group apply from 01.01.2013 the revised standard IAS 19 "Employee benefits" with retroactive application from 01.01.2012
according to IAS 8 " Accounting Policies, Changes in Accounting Estimates and Errors". A fundamental change in the new model
is the immediate recognition of actuarial gains and losses and of past service costs arising from defined benefit plans that are
transferred under the Margin policy under previous IAS 19.

The accompanying notes on pages 188 - 256 form an integral part of the present Financial Statements
The Company receives subsidies from the European Union, through the Greek State, in order to finance certain projects.
Furthermore, the Company’s customers (including the public sector and the local government authorities) participate in the
financing scheme of the initial network development cost (meters, network connections, etc.) or its upgrade.
The related one-off charges that were charged to customers before the 30th of June 2009 (i.e. earlier than the effective date of
IFRIC 18 which was not applied retrospectively) were accounted for by the Company as deferred income and recognized in
income over the useful life of the relevant fixed assets.
With the adoption of IFRS 15, the amount of € 33,259 k that was included as deferred income in the Statement of Financial
Position as at 1st January 2018 under the heading "Investment Subsidies and Customer Contributions" was recognized in
retained earnings of the Company and the Group.

Fiscal Year 01.01.2021 – 31.12.2021

The above subsidies and income from rights 22% are accounted for at the time of receipt and are recorded in the Statement of
Financial Position in the long-term liabilities. These amounts constitute deferred income and are depreciated on the basis of the
economic life of the relevant assets, at the time their operation commences. The amortization of subsidies and income from
rights 22% are deducted from the depreciation of fixed assets in the income statement.
Apart from the above, the Company has also received other type of state subsidies such as the granting of a concession to
Psitalia island, which EYDAP utilizes for the operation of the waste treatment management.
31. CONSUMERS’ GUARANTEES
The amounts of € 18,911 k on 31.12.2021 and of € 18,749 k on 31.12.2020 concern customer guarantees for the use of the water
meter, paid at the time of water supply connection. The above guarantees are paid back (free of interest) upon request from the
customer for termination of the water supply connection. The above guarantees have been recorded in nominal value, and not
at fair value, initially, and in a following stage in their net (amortized) cost, since they can be claimed from the customers at any
time.
32. LIABILITY UNDER THE EXCLUSIVE RIGHT TO PROVIDE RAW WATER
Based on the contracts signed on 02.02.2022 between the Greek State, EYDAP Fixed Assets (EPEYDAP) and EYDAP SA.

supply raw water for the period 2021-2040. The relevant reference is made in Note 14. The consideration paid for the intangible
exclusive right to supply raw water was set at Euro 87,500 k. During the closing fiscal year part of this obligation was offset at the
request of the Company of the External Water Supply System, amounting to Euro 25,000 k, with the consequence that the
amount of this obligation is set at Euro 37,500 k on 31.12.2021.

par. 2 of Article 2 of Law 2744/1999 and the contract dated 09.12.1999 between the Greek State and the Company and the
Greek State to EYDAP SA for the period from 12.10.2013 to 31.12.2020. As mentioned in the aforementioned Notes, with the
JMD issued in the Government Gazette 5830 14/12/2021 it was determined that the consideration owed by EYDAP SA for the
amount of raw water supplied during the period from 01.10.2013 to 31.12.2020, amounted to Euro 346.7 million, while its
receivable for the provision of management, maintenance and supervision services of the sound operation of the EYS during the
same period amounted to Euro 189.5 million. The same JMD decided to offset the above receivables between the Greek State
and EYDAP SA and the payment of the balance amounting to approximately Euro 157.2 million to be implemented from the
latter after the offset.
The payment of the aforementioned amount of Euro 157.2 million did not burden the Company’s results in the closing year, as a
relevant provision had been made for the year ended 31.12.2020.

38. EYDAP FIXED ASSETS “EYDAP L.E.P.L.”
1. “EYDAP Fixed Assets Legal Entity of Public Law L.E.P.L.” was established at the time of the Company’s public listing (IPO)
aiming at transferring the ownership of the water dams and basins of Marathon, Mornos, Yliki and Evinos. Apart from the
constructions and the expansions of the facilities which are connected to the above dams and basins, the Greek State
through “EYDAP Fixed Assets L.E.P.L.” supplies the Company with raw water so that the Company is in position to fulfill its
obligations with regard to the provision of water supply services.
2. It is to be noted that:
• the Aqueduct of Yliki until the Viliza in Thiva was transferred to the competent Land Registry of Thiva and Oropos.
• The construction sites of Amfissa and Chrissos in Delphi have already been incorporated into the competent office of
Amfissa which operates as Land Registry.
3. The Board of Directors of “EYDAP S.A.” with the decision 18448/ 24.09.2014 approved the signing of an agreement
between “EYDAP Fixed Assets Legal Entity of Public Law L.E.P.L.” and “EYDAP S.A.” concerning the water supply and invoicing,
since 1/10/2014, of the local government authorities and other legal entities of public law from “EYDAP Fixed Assets L.E.P.L.”
along the External Water Supply System which concerns geographic areas beyond the jurisdiction of “EYDAP S.A.”.
Particularly, the above decision concerned the following Municipalities:
• Delfoi
• Leivadia (and of DEYAL)
• Thiva (and of DEYATH)
• Tanagra
• Chalkida (and of DEYACH)
• Distomo – Arachova

4. In compliance with the contract signed on 02.02.2022 of L.4812 / 2021 between the Greek State and EYDAP SA, EPEYDAP is
the exclusive provider of water services outside the area of activity, maintaining the exclusive right to supply water to
individuals along its external water supply system (Article 5.5.1). In this context, the procedure of subcontracting individuals'
contracts to EPEYDAP is carried out.
39. CAPITAL MANAGEMENT
The Company manages its capital in such way in order to meet its objectives as these are mentioned in paragraph 4a of article 1
of Law 2744/99. In addition, according to paragraph 8 of the same article the placement of its fixed real estate assets used for
water supply and sewerage purposes as collateral is prohibited. It is noted that according to article 5 of the same law there is no
provision for compulsory administration of the assets of EYDAP used for water supply and sewerage purposes.
In the current period, the Company does not possess any bank liability either long-term or short-term. Following its listing on the
Athens Exchange in 2000 and until 2013, the Company held mainly short-term debt, in order to meet its operating needs due to
the fact that it had not collected payments for water supply bills from certain municipalities and other public entities.
The Company maintains sufficient capital in order to serve its business objectives and to apply the appropriate dividend policy.

Trade and other receivables are included in receivables from private clients for which there is a relative risk, which is limited by
measures and actions taken by the competent directorates. The actions concern the assumption of measures in order to deal
with the arrears of due liabilities and the provision of facilities for their repayment.
For the category of local government liabilities, the Company examines the possibility of collecting arrears through the signing of
contracts (network management or settlements) or through regulatory arrangements.
The Group and the Company have revised the methodology for measuring the impairment of financial assets in accordance with
IFRS 9.

It is noted that the repaid amount of the installments and of the arrangements with private customers on 31.12.2021 stands at
Euro 7,575 k compared to Euro 11,586 k recorded in the corresponding period last year and is not included in the balance of
private customers, in the time analysis table.
The Department of Revenue & Trade Receivables Management, as well as the Department of Special Customers Management,
continuously monitor the claims of the Company, either separately or based on groups (invoice codes, customer categories) and
incorporate this information into the credit risk control procedure.
With regard to credit risk management, the Department of Collection Enforcement of the Department of Revenue & Trade
Receivables Management reviews on constant basis and settles via judicial procedures (LD 356/1974 “Code for the Collection of
Public Revenues”) overdue receivables concerning water supply, utilization rights and property connection rights from retail
customers and local government authorities (OTA).
The cash and cash equivalents are subject to an impairment test in accordance with the requirements of IFRS 9 and the
estimated impairment loss is not judged as significant. Credit risk management is carried out by aggregating the largest part of
the Company's assets into the Bank of Greece (approximately 60%) and by limiting the exposure to other credit institutions
(mainly systemic banks).
None of the financial assets has been placed as collateral or in any other form of credit insurance.
Correspondingly, the Company has not assigned to third parties as a form of guarantee financial instruments through Assets.

(b) Liquidity Risk
The liquidity risk is being managed by the preservation of sufficient cash available and by the assurance of bank credits for use.
There is no liquidity risk due to the existence of sufficient cash reserves which can cover the current operating and investment
needs.

(c) Market Risk
Market risk is related to the Company's equity portfolio, which is a long-term, strategic investment and as a result is limited to
pre-defined Position Limits.
(d) Regulatory risk
Signing the new contract with the Greek State places the Company in a new regulatory framework under JMD 135275/2017,
Government Gazette 1751 / Β / 22-5-2017 “Approval of general rules for costing and pricing of water services. Method and
procedures for recovering the cost of water services in its various uses. ", under the provisions of Article 3 par. 1 of Law
3199/2003 (A’ 280) "Water protection and management - Harmonization with Directive 2000 / 60 / EC of the European
Parliament and of the Council of 23-10-2000". The contract has retroactive effect from 1/1/2021 as well as the implementation
of the new regulatory framework, which is expected to be finalized in 2022. According to paragraph 5 of Article 114 of Law
4812/2021, the validity of the EYDAP SA tariffs is extended for the provision of water services it offers to its consumers, which
have been approved by the JMD D6 / 2027 / 16.12.2013 of the Ministers of Finance, Transport and Networks and Environment,
Energy and Climate Change (Β'3188), for period from 1.1.2019 until the approval of the new invoices based on the new contract.

The new tariffs that will be formed under the JMD 135275/2017, will enable the recovery of the cost of raw water as well as the
increased energy costs.
The objective of JMD 135275/2017 is the approval of general rules for costing and pricing of water services for various uses and
rules and measures to improve these services, as well as defining the procedures and method of recovering the cost of these
services, including environmental costs and the cost of water resource, according to Article 12 of Law 3199/2003, as effective
and Article 8 in combination with Article 12 of p.d. 51/2007, as effective, in order to achieve the sustainable use and the
improvement of water conditions, in accordance with the environmental objectives of Article 4 of the aforementioned p.d. and
to ensure the constitutionally guaranteed public character of water as a social asset absolutely necessary for human life.
In particular, the main objective of the JMD is to ensure:
(a) that the water pricing policy provides sufficient incentives for users to use water resources efficiently; and
(b) an adequate contribution of miscellaneous uses of water to the recovery of the cost of water services at a rate specified in
the approved river basin management plans taking into account, where appropriate, the social, environmental and economic
impacts of the rehabilitation as well as the geographical and climatic conditions .
EYDAP has sent since January 28, 2022 a letter to the Ministry of Environment and Energy, as the Competent Authority for the
implementation of the general rules of costing and pricing of water services, in order to answer specific questions and launch the
necessary actions to define the new regulatory framework.
According to the report of the European Commission that accompanied the approval of the Greek plan approved for inclusion in
the Recovery Fund, the Greek Government has undertaken the commitment to establish the new water and wastewater
regulatory authority, with the implementation of this reform being the Ministry Environment and Energy. The reform seeks to
strengthen and optimize water management through the establishment and operation of a National Water Regulatory Authority.
The Authority will assume clear and specific responsibilities and competences, which will arise as a result of study and extensive
consultation with all stakeholders. The operation of the Authority will be based on Directive 2000/60 / EC, as incorporated into
national law. The new authority is expected to strengthen the institutional framework and supervision of the segment, including
rationalization of water pricing policy under the "polluter pays" principle, and ensuring the sustainability of water services in
Greece. The implementation of the reform will be completed, according to the report on this reform, by 31 December 2023, a
milestone in which the new Authority must be staffed and equipped. As for the intermediate steps, in a relevant table it was
referred to as "entry into force of a law for the establishment and operation of a new regulatory authority for water and
wastewater" in the last quarter of 2022.
Until today, the invoice approved as published in the Government Gazette 3188B / 16.12.2013 continues to be valid.
(e) Risk due to COVID-19 Pandemic
On March 11, 2020, the World Health Organization officially designated the coronavirus (Covid-19) epidemic as pandemic.
Corporate Policy
Immediately after the outbreak of the pandemic, the Company’s Management started monitoring the developments, evaluating
the risks and taking the necessary actions aimed at protecting its Employees and Customers, facilitating, at the same time,
uninterrupted provision of water supply and sewerage services. Guided by the corporate social responsibility towards its
employees and the citizens, from the very beginning, EYDAP harmonized its operation with the special health protocols issued
by the National Public Health Organization (EODY) and the legal provisions (Legislative Content Acts) of the Greek State.
A Special Crisis Management Team (SCMT) was immediately set up for Covid-19, which coordinated all the actions aimed at
prevention and protection of employees and customers and Covid-19 Coordinating Manager was appointed, whose
responsibilities included coordinating the actions in case of Covid-19 incident in the Company. Individual protective equipment
(antiseptics, masks, gloves) have been distributed to all services and facilities, while the possibility of remote work has been
provided. Regular disinfection is conducted in all the workplaces, while emergency disinfections are performed in case of in case
of Covid-19 incident.
To facilitate protection of the customers, the Company encouraged the consumers to carry out their transactions or requests
through the Company’s digital channel, thus drastically limiting the attendance at the Regional Centers.
EYDAP has effective agreements with private diagnostic laboratories that test its employees and their family members to
facilitate better management of in-service dispersion.

Another significant factor in dealing with the pandemic is the highest vaccination rate of the staff that reaches 85%, making
EYDAP a Covid-Free Company. IN this difficult pandemic period, the Company’s employees, who for so many years care for and
offer the most valuable goods of highest quality with a sense of responsibility and contribution to the common good, are almost
all vaccinated, thus offering their customers and themselves a sense of security.
Moreover, the Company participates in the private certification scheme CovidShield and is committed to a series of actions,
constituting the Covid Shield Corporate Policy, disclosed on the corporate website at the following link:
https://www.eydap.gr/SocialResponsibility/BusinessPractice
EYDAP, it received certification from the international certification organization TUV for the management system it applies.
Consumption
In 2021, consumption was not affected by the pandemic.
Investment plan - Supply chain
The absorption of the investment program in 2021 stood at 57.75%, compared to 2020, when the absorption was 55.42% (of
the annual budget). There was no significant issue regarding the supply of raw materials.
Collectibles
The Company continuously monitors the evolution of collectibles and overdue receivables, in order to take the appropriate
measures where necessary. In 2021, the Company’s collectibles were not affected by COVID-19 pandemics with the exception
of suspension of invoices caused by involvement in tenders (see Significant Events, p. 19).
Water supply – Sewerage
The Company did not encounter any problems regarding Covid-19 in the operation of its core business.
Customer Service
During the COVID-19 period, the Company enriched the range of electronic services offered to customers through its site and,
as a result, the customers are now in position to make most their requests electronically. In September 2021, the upgraded
application for mobile phones and tablets Eydapp was launched, through which customers, among other things, can easily and
safely pay their bill without switching to another digital environment.
Health Coverage
The staff of EYDAP and their protected members are covered by the health fund of the Company and with group insurance.
During the coronavirus crisis, all relevant instructions have been given to the staff and digital prescription has been
implemented.
Further details regarding safety measures against coronavirus are presented in the section "Employee Health and Safety".
41. FAIR VALUE DETERMINATION
The fair value of the financial assert, are traded in active markets (stock exchanges) (i.e. derivatives, stocks, bonds, mutual funds)
is determined based on their published price quotations, effective on the financial statements’ reporting date. Available for sale
financial assets are measured at fair value, which is their market price, and, therefore, are classified in Level 1, according to the
provisions of IFRS 7, par. 27B.
The fair value of financial assets, not not traded in active markets, is determined, applying valuation techniques and
assumptions, based on market data on the Financial Statements reporting date.
It is estimated that the nominal value less provisions for impairment of trade receivables approximates their actual value. The
actual values of financial liabilities for presentation purposes in the financial statements are calculated based on the present
value of their future cash flows, applying the effective interest rate, available for the Company for using similar financial
instruments.

42. SUBSEQUENT EVENTS
Public & Private Partnerships (PPP) tender for the Operation, Maintenance, Repair and Restoration of the Fixed Assets of the
External Water Supply System (EWSS)
The financial statements and the presentation of the financial results of 2020, posted on the Company's website, make
reference to the fact that the framework of the agreement with the Greek State "includes regulation of institutional issues,
such as the possibility of EYDAP participating in PPP tenders".
Moreover, in the first half-year financial statements for 2021, it is recorded that with a contract between the Greek State
represented by the Minister of Infrastructure and Transport, the "EYDAP Fixed Assets Company" and EYDAP SA, it is assigned to
EYDAP SA. the maintenance and operation of the External Water Supply System (EWSS) of the major area of the Capital for three
years. After the expiration of this contract, the maintenance and operation of EWSS will be assigned by the Ministry of
Infrastructure and Transport to a contractor, who will be promoted through a tender procedure in accordance with Law
3389/2005 (A '232), in which EYDAP intends to participate in a tender procedure.
Based on documented studies of EYDAP services and the opinion of an external legal advisor, the participation of EYDAP in the
relevant tender is possible only if the founding law of the company is amended. It is noted that the founding law of EYDAP was
made long before the implementation of Public-Private Partnerships (PPPs) and therefore does not provide for the possibility of
EYDAP to participate in PPPs outside the Attica Region, where it operates.
The amendment of the founding law was not made until the deadline for submission of an expression of interest file on
20/1/2022, despite the relevant actions of the Company, and therefore, EYDAP can not participate in the first phase of the above
tender.
EYDAP will continue to operate and maintain the External Water Supply System (EYS) until the end of its relevant contract, as it
has successfully done for the last 40 years, providing uninterrupted quality and affordable water in Attica, through accumulated
know-how and experience.
Decisions of the SC no. 190-1 / 2022
On February 4, 2022, the nos. 190-1 / 2022 decisions of the Plenary Session of the Council of State were published, which
deemed unconstitutional the transfer of the majority of the Share Capital of EYDAP SA and EYATH SA to the Hellenic Corporation
of Assets and Participations S.A. by Law 4389/2016. The Hellenic Corporation of Assets and Participations S.A. holds direct voting
rights for 50.003% of the share capital of EYDAP and indirect voting rights for 11.33% of the share capital through the HRADF.
EYDAP has not received any notification until the disclosure of the financial results.
Payment to EPEYDAP of post due debts for the years 2013-2020
The JMD no. 352462 / 14.12.2021 (Government Gazette 5830) of the Ministries of Finance, Development & Investment,
Environment & Energy, Infrastructure & Transport re-regulated both the post due debts of EYDAP to the Greek State for the
consideration for raw water supply for the period 2013-2020 and the operating expenses of EYDAP SA for the management,
maintenance and supervision of sound operation of EYS during the period from 01.10.2013 until 31.12.2020. At the end of the
year 2021, receivables and obligations of the parties were invoiced, namely:
• EPEYDAP invoiced the amount of Euro 346.7 million for the quantities of raw water provided by the Greek State
(through the company EPYDAP) and respectively
• EYDAP SA invoiced the total amount of Euro 189.5 million which is analyzed in receivable of:
1. The amount of Euro 1.1 million arising from the execution of projects of the External Water Supply System and
2. The amount of Euro 188.4 million arising from the provision of operation services, maintenance of the External
Water Supply System
for the years from 2013 to 2020. On 08.02.2022 the payment of the amount of approximately Euro 157 million was implemented
to EPEYDAP.
Risk from the Geopolitical Crisis in Ukraine - Energy Crisis

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
247
The current geopolitical crisis in Ukraine in line with the consequent sanctions on Russia from the European Union, have brought
about significant uncertainty to the economic environment at both - national and pan-European as well as global levels. EYDAP is
not directly exposed in these areas, therefore there is no direct impact on its operations.
However, the geopolitical crisis, combined with the pre-existing energy crisis, has led to a further increase in energy costs, in
particular gas, which has affected the market causing price increases. It is pointed out that in general there is an increase in
prices of a variety of commodities (such as Aluminum, Nickel, Copper, Tin, Wheat, Soybean, Corn) and not only in energy
products that are at historical highs of 5 years.
In the event this increase affects - to some extent - the products and services used by consumers - customers, the family and
business budgets may be burdened and a redistribution may occur in the family budget of the consumer - customer, so there
may be a lag of their due payments to EYDAP.
Moreover, increases in the energy sector are likely to have an adverse impact on the segments such as tourism, provision of
hotel services, which will, in turn, lead to a potential reduction in consumption and revenue in the Corporate Invoice (to
companies granted). In the other invoices, due to the inelasticity of the product, the above mentioned sizes are estimated to
remain at the same levels. Inflationary pressures are therefore expected to weigh on both our customers and our suppliers
Regarding liquidity, currently there is no impact on the Company's collections. However, it is important to define the regulatory
framework that will determine the new tariff according to JMD 135275/2017, Government Gazette 1751 / Β / 22-5-2017
"Approval of general rules for costing and pricing of water services. Method and procedures for recovering the cost of water
services in its various uses.", in order to recover the cost of raw water and increased energy costs.
The increase in prices is likely to lead to delays and difficulties in some of the Company's projects as the prices of materials, and
therefore the initial budgets of the projects, have increased significantly between the period between the submission of the
proposal by the contractor and the execution of the project. Many contractors are therefore unable to complete projects they
have undertaken or not sign new contracts they have undertaken as implementation costs are prohibitive. The contractors have
submitted requests to the Ministry of Infrastructure in order to facilitate the construction market through legislation.
EYDAP Management takes the necessary measures in order to minimize any consequences. Stocks of particularly critical water
supply network materials are constantly recorded and the immediate supply of materials that are deemed necessary is carried
out. Currently, the Company does not face any problem of insufficiency of materials or their supply.
Due to the volatility of the conditions in Ukraine, it is not possible to accurately assess the economic impact. The Company
Management monitors the developments and evaluates possible further effects on its operation and results.
The ongoing energy crisis combined with the geopolitical crisis in Ukraine have created unfavourable conditions regarding rising
costs along the production chain. From January 2022, the state subsidy for the Medium Voltage started, specifically 65 € / MWh,
therefore the cost of electricity for the Medium Voltage is estimated at 220 € / MWh and for the low at 240 € / MWh. Based on
current prices and state subsidies, energy costs for 2022 are projected to standa at € 43.4m, increased by 69.5%.
After the on-going increases in electricity prices, in order to reduce operating costs, EYDAP SA:
1. is in the process of finding an electricity supplier through a tender, in order to reduce the supply costs (more competitive
energy and power tariff prices and higher discounts).
2. has launched studies and tenders in its energy-intensive facilities for the replacement of old equipment, eg pumps, with more
energy efficient ones.
3. plans to install energy control systems (monitoring) in the facilities to improve their energy performance.
4. has launched tender procedures to develop PV stations with energy offset, in order to reduce the total consumption of
electricity.
Regarding the existing RES units, the current contracts for both M.Y.H.S. as well as for the existing PV 1.97 MW, relate to fixed
prices.

respects, the financial position of the Company EYDAP S.A. and its subsidiaries (the Group) as at December 31st,
2021, their financial performance and their cash flows for the year ended in accordance with International Financial
Reporting Standards that have been adopted by the European Union.
Basis for Opinion
We conducted our audit in accordance with International Standards on Auditing (ISAs) incorporated into the Greek
Legislation. Our responsibilities under those standards are described in the “Auditor’s Responsibilities for the Audit
of the Separate and Consolidated Financial Statements” section of our report. We are independent of the Company
within our entire assignment in accordance with the International Ethics Standards Board for Accountants’ Code of
Ethics for Professional Accountants (IESBA Code) incorporated into the Greek Legislation and ethical requirements
relevant to the audit of separate and consolidated financial statements in Greece and we have fulfilled our ethical
responsibilities in accordance with these requirements and the IESBA Code. We believe that the audit evidence we
have obtained is sufficient and appropriate to provide a basis for our opinion.
Key Audit Matters
Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the
separate and consolidated financial statements of the current period. These matters, as well as the related risk of
significant misstatements, were addressed in the context of our audit of the separate and consolidated financial
statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these
matters.
Key Audit Matter
Audit Approach
Revenue recognition

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
249
The turnover of the Company and the Group
amounted for the year ended 31/12/2021 to €
360,7 mil., (€ 330,3 mil. for the year ended
31/12/2020).
Periodic counting and invoicing based on the
current consumption invoices of approximately
2.2 mil. supplies are required in order to
recognize the company’s revenue.
Revenue recognition as well as updating the
accounting systems is performed automatically
through the company's subsystems. The
Company uses information systems and internal
controls in order to ensure an integrated revenue
recognition framework.
Revenue recognition has been defined as a key
audit matter since it is a complex issue associated
with the high volume of transactions, use of
information systems in order to update the prices
and revenue recognition, in line with the
management’s judgments and estimates.
The Company’s disclosures concerning the
accounting policies, followed regarding revenue
recognition, are recorded in notes 3 and 5 to the
financial statements.
Our audit approach included, among
others, the following procedures:
• Review of the IT systems
environment, including internal
procedures and related security
controls.
• Review of correct data transfer
from individual information
systems to the general accounting
trial balance.
• Discussion with the management
and assessment of the internal
controls in respect of the
procedure of estimating revenue
for consumed and non-priced
amount of water and the
corresponding revenue from
rendering sewerage services.
• Review of mathematical accuracy
of the calculations and sound
accounting treatment of the
amounts.
• Services of an Auditor’s special
expert were used regarding the
aforementioned procedures, when
deemed necessary.
• Assessment of adequacy and
suitability of the disclosures
recorded in the separate and
consolidated financial statements
Recoverability of trade receivables
As at 31/12/2021 the trade receivables of the
Company and the Group amounted to € 225,6
mil. including accumulated impairment loss
allowance of € 103,4 mil. (178,9 mil. and 99,6 mil.
as at 31/12/2020).
The Company applies the simplified approach
under IFRS 9 "Financial Instruments" and
calculates the expected credit losses throughout
the entire life of their trade receivables. In order
to calculate the expected credit losses, historical
data are used that reflect the expected impact of
the current data in the future.
Our audit approach included, among
others, the following procedures:
• Review of internal controls in
place, in respect of trade
receivables impairment test.
• Obtaining and reviewing the
calculation of trade receivables
impairment performed by the
management, assessing, inter
alia, completeness and accuracy
of the data used to determine the
expected credit losses as well as

Graphics
Annual Financial Report
Fiscal Year 01.01.2021 – 31.12.2021
250
We have defined the procedure of trade
receivables impairment test as one of the key
audit matters given the amount of these accounts
in line with the significance of the management’s
assumptions and estimates applied under this
procedure.
The Company’s and the Group’s disclosures
regarding the accounting policy, judgments,
estimates and assumptions used under the trade
receivables impairment test are recorded in
notes 3 and 22 to the separate and consolidated
financial statements.
the assumptions, on which the
Management based its
estimates.
• Review of mathematical
accuracy of the calculations and
sound accounting treatment of
the amounts.
• Assessment of adequacy and
suitability of the disclosures
recorded in the separate and
consolidated financial
statements.
Employee benefits obligations
The Company is required to cover the medical
cost of employees, retired employees and
dependent members of their families. It is also
required to pay employee lump sum retirement
benefit and specific lump sum retirement benefit,
according to the current labour law and the
collective labour agreement of the personnel.
These benefits are treated by the Management
as a defined benefit plan and the estimate of the
obligation is made according to IAS 19. The
Management used independent actuaries in
order to determine the appropriate assumptions
regarding the variables, such as the level of
inflation, discount rate, future increases in
salaries, mortality rate and the preparation of the
relative study.
Moreover, assisted by independent actuaries, the
Management reviewed the impact of the IFRIC
decision "Allocation of benefits to periods of
service service (IAS 19)" (the "Decision"), on the
methodology it applies for recognition of
retirement benefits and decided to continue
applying the same allocation method as followed
in the actuarial studies for the previous years.
Given the size (approximately € 345 mil.) and the
sensitivity of the liability amount to various
parameters – the assumptions mentioned above
- we have defined assessment of employee
benefits as one of the key audit matters.
The respective Management’s disclosures in
respect of employee benefits obligations
Our audit procedures applied in respect
of assessing this matter included among
others, the following procedures:
• Review of the policy regarding
recognition of the relevant
liability in relation to the
provisions of IAS 19
• Review – conducted with the
assistance of an actuary - of the
Management's assessment of
the impact of the IFRIC decision
regarding the allocation of
benefits to periods of service. In
our review, we took into account
SOEL Clarifying Guidelines,
Instructions of SOEL, provisions
of the Special Collective Labour
Agreement ("ESS") special
collective labour agreement as
of 02/07/91 and the studies of
the Company's actuaries.
• Review and reconciliation of the
data and information provided
by the Company's Management
to the external actuaries,
regarding the Company's
personnel.
• Evaluation, with the assistance
of a specialized technical
actuarial consultant, of the

actuarial assumptions and the
calculations of the actuarial
study as of 31/12/2021.
• Sample dased review of the
calculation and accounting
treatment of the benefits paid to
employees in the year under
audit.
• Assessment of adequacy of the
disclosures made by the
Management in compliance with
IAS 19 in note 28 to the financial
statements.
The right of exclusive raw water supply
On 02/02/2022, pursuant to paragraphs 1, 2 and
4 of Article 114 of Law 4812/2021, the contracts
was signed between the Greek State, the legal
entity under public law EPEYDAP and EYDAP SA.
The relevant contract under Law 4812/2021
(Exclusive Right Contract) grants the right of
exclusive supply of raw water to EYDAP and
agrees on the annual supply of raw water for
twenty years effective from 1.1.2021 to
31.12.2040, as specifically defined in Article 10 of
the aforementioned contract.
Based on the above contract and the relative
memorandum of understanding, signed between
the contractual parties, the consideration paid for
the right of exclusive raw water supply for twenty
years effective from 1.1.2021 to 31.12.2040 was
determined amounting to Euro 87,500,000, as
presented in the table above.
Given the significant size of the intangible asset
that was recognized, and the complex terms of
the contracts, signed between EYDAP SA, the
Greek State and EPYDAP, we have defined this
issue as one of the key audt matters.
Our audit procedures included
among others, the following
procedures:
• Receiving and reviewing the
relevant contracts and the
memorandum of understanding
signed between the contractual
parties (Greek State, EPEYDAP
and EYDAP SA).
• Review of fulfillment of the
conditions set for recognition of
the intangible Right of exclusive
raw water supply based on the
provisions of IAS 38.
• Examination of sound calculation
of amortization of the Right of
exclusive raw water supply in the
period of twenty years of its term.
• Assessment of adequacy of the
disclosures made by the
Management in compliance with
IAS 38 in note 14 to the financial
statements.
Other Information
Management is responsible for the other information. The other information included in the Annual Financial Report
includes the Board of Director’s Report, the reference to which is made in the “Report on Other Legal and Regulatory

Our opinion on the separate and consolidated financial statements does not cover the other information and we will
not express any form of assurance conclusion thereon.
In connection with our audit of the separate and consolidated financial statements, our responsibility is to read the
other information and, in doing so, consider whether the other information is materially inconsistent with the
separate and consolidated financial statements or our knowledge obtained in the audit, or otherwise appears to be
materially misstated. If, based on our audit, we conclude that there is a material misstatement therein, we are
required to communicate that matter to those charged with governance. No such issue has arisen.
Responsibilities of Management and Those Charged with Governance for the Separate and Consolidated
Financial Statements
Management is responsible for the preparation and fair presentation of the separate and consolidated financial
statements in accordance with International Financial Reporting Standards that have been adopted by the European
Union and for such internal control as management determines is necessary to enable the preparation of separate
and consolidated financial statements that are free from material misstatement, whether due to fraud or error.
In preparing the separate and consolidated financial statements, management is responsible for assessing the
Company’s and the Group’s ability to continue as a going concern, disclosing, as applicable, matters related to going
concern and using the going concern basis of accounting unless the management’s intention is to proceed with
liquidating the Company and the Group or discontinuing their operations or unless the management has no other
realistic option but to proceed with those actions.
The Company’s Audit Committee (Article 44, Law 4449/2017) is responsible for overseeing the Company’s and the
Group’s financial reporting process.
Auditor’s Responsibilities for the Audit of the Separate and Consolidated Financial Statements
Our objectives are to obtain reasonable assurance about whether the separate and consolidated financial
statements as an aggregate, are free from material misstatement, whether due to fraud or error, and to issue an
auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee
that an audit conducted in accordance with ISAs, incorporated into the Greek Legislation, will always detect a
material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if,
individually or in the aggregate, they could reasonably be expected to affect the economic decisions of users taken
on the basis of these separate and consolidated financial statements.
As part of an audit in accordance with ISAs, incorporated into the Greek Legislation, we exercise professional
judgment and maintain professional skepticism throughout the audit. We also:
• Identify and assess the risks of material misstatement of the separate and consolidated financial statements,
whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit
evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material
misstatement resulting from fraud is higher than that resulting from error, as fraud may involve collusion,
forgery, intentional omissions, misrepresentations, or the override of internal control.
• Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the
Company’s and the Group’s internal control.

Fiscal Year 01.01.2021 – 31.12.2021

• Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and
related disclosures made by the management.
• Conclude on the appropriateness of management’s use of the going concern basis of accounting and, based on
the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast
significant doubt on the Company’s and the Group’s ability to continue as a going concern. If we conclude that a
material uncertainty exists, we are required to draw attention in our auditor’s report to the related disclosures in
the separate and consolidated financial statements or, if such disclosures are inadequate, to modify our opinion.
Our conclusions are based on the audit evidence obtained up to the date of our auditor’s report. However,
future events or conditions may cause the Company and the Group to cease to continue as a going concern.
• Evaluate the overall presentation, structure and content of the financial statements, including the disclosures,
and whether the separate and consolidated financial statements represent the underlying transactions and
events in a manner that achieves fair presentation.
• Obtain sufficient appropriate audit evidence regarding financial information of entities or business activities
within the Group for the purpose of expressing an opinion on the separate and consociated financial statements
to be able to draw reasonable conclusions on which to base the auditor’s opinion. Our responsibility is to design,
supervise and perform the audit of the Company and its subsidiaries. We remain solely responsible for our audit
opinion.
We communicate with those charged with governance regarding, among other matters, the planned scope and
timing of the audit and significant audit findings, including any significant deficiencies in internal control that we
identify during our audit.
We also provide those charged with governance with a statement that we have complied with relevant ethical
requirements regarding independence, and to communicate with them all relationships and other matters that may
reasonably be thought to bear on our independence, and where applicable, related safeguards.
From the matters communicated with those charged with governance, we determine those matters that were of
most significance in the audit of the separate and consolidated financial statements of the current period and are
therefore the key audit matters.

Taking into consideration the fact that under the provisions of Par. 5, Article 2 (part B), Law 4336/2015, management
