storm water pipes), except in the area of the center of Athens, where the system is pantorrhoic (joint dirty and rain
water pipes). The served population amounts to 3,695,500 inhabitants. Wastewater is collected through the pipes
of the secondary sewage network of the drained areas, through the connection to them of each temporary property,
which (connection) is mandatory for the owners of the properties, within six (6) months of the relevant written
notification of EYDAP in accordance with the provisions of article 169 of Law 4951/2022 and on penalty of imposing
a fine in favor of the Greek State.
For the treatment of wastewater, EYDAP now has 5 wastewater treatment plants (WWTP.),
the WWTP Psittalia with the possibility of processing (average design flow) 1,000,000 m3/day of
wastewater (today the average flow of incoming wastewater is of the order of 730,000 m3/day),
the WWTP Metamorphosis has the ability to treat (average design flow) 44,000 m3/day of wastewater
(20,000 m3/day urban wastewater and 24,000 m3/day urban sewage), (today the average flow of incoming
sewage is 12,000 m3/day and the sewage of the order of 12,000 m3/day) and
the WWTP Thriasiou has the capacity to treat (average design flow) 21,000 m3/day of wastewater (today,
the average flow of incoming wastewater is of the order of 6,000 m3/day
the WWTP Megaron which was received by the Municipality of Megaron in September 2023. The capacity
of the constructed facility is 43,330 (I.P.) and the average daily design flow of incoming sewage is 8,000
m3/d.
the WWTP Peanias-Koropiou was taken over by the Region of Attica in December 2023. The existing
installation of the Koropio-Peanias Wastewater Treatment Center has the capacity to treat wastewater
equivalent to a population equal to 99,486 i.c.
The Psittaleia WWTP includes three Combined Heat and Power (CHP) units, one natural gas-fired CHP unit with an
electrical capacity of 12.9 MWe and a thermal capacity of 17.3 MWth, and two CHP units with Biogas combustion,
with a total electrical capacity of 11 ,4 MWe (7.14 MWe & 4.25 MWe) and a thermal power of 17.2 MWth as well as

EYDAP with the Psittalia Wastewater Treatment Center has joined the Greenhouse Gas Emissions Trading System of
the European Union, applying the corresponding EU and national legislation.
In addition, EYDAP manages the drainage projects of Eastern Attica for the collection and treatment of urban
wastewater and the reuse-disposal of treated effluents. In 2023, significant progress was made in the
implementation of sewage projects. The design of the construction and operation of integrated wastewater
management systems in Eastern Attica includes projects in the areas of the Municipalities of Rafina - Pikermio, Spata
Artemisa, Marathon, Pallini, Paiania, Saronikos and Kropia. In 2021 EYDAP developed the special katharonero
website . eydap . gr for the continuous information of the citizens about important drainage projects of Eastern
Attica and the environmental benefits of the projects.
In the context of the optimization of its energy balance and the utilization of renewable energy sources EYDAP: a)
has installed and operates five small hydroelectric plants at the Kirfi, Helikona, Kithairona, Mandra sites of the
Mornos Aqueduct and the small Evinos hydroelectric plant and b) has installed a photovoltaic (PV) plant with a power
of 1.9712 MW, at its facilities in the Municipality of Acharna, in order to sell the electricity produced.
EYDAP supplies Attica with one of the highest quality waters in the world. The main sources of water abstraction
and the reservoirs used are located in pristine areas, free from agricultural and industrial activity, as a result of which
the Greek capital is supplied with excellent quality water, while its transport is carried out naturally by gravity, with
little energy consumption.
Our vision is the uninterrupted provision of high quality water and sewerage services in Athens and the rest of
Greece by a model company in terms of ESG and zero carbon water.
Our strategy is based on achieving a balanced and sustainable development for the benefit of society, customers,
employees, shareholders, the environment, and all those who have a legitimate interest in it. The three axes of our
strategy are Safety, Efficiency and Development.

revenue recognition criteria, are deducted from revenues and therefore are recognized as revenues only
upon the cash collection from the customer.

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

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

Graphics
18
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).
Reconciliation Table of ROE at GROUP level
By means of analysing 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 Companys 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.

Adjusted EBITDA
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 the granting of a lower price for the real estate than the original). 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 adjustments first recorded in the Financial Statements of 2020 in relation to raw water
and finalized in 2021 with 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 sales, distribution expenses, administrative expenses, other
expenses are deducted from turnover and 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. The cost of raw water based on the agreement is added to the relevant sum
(because it is included in the cost of sales) while revenue of operation and maintenance contract (included in the
turnover).

ΙΙ. Operations Review Development of water consumption and income from water supply and right-of-use
sewerage
Total consumption in 2023 remained at about the same level as in 2022, showing a slight decrease of -0.1%.
The following contributed to the formation of the consumption level, compared to the previous year:
-0.4% reduction in the water supply aid for the areas of the Municipality of Oropos, with water pumped
from the Mavrosovala boreholes,
by -0.3% the interruption of other water supplies of undiluted water along the External Water Supply
System, in application of the contract of Law 4812/2021, signed between the Company and the State, and
in the opposite direction, +0.6%, increase in the outgoing quantity from the Water Treatment Plants (WTPs).
Regarding the evolution of water consumption in WTPs, which constitutes 99% of total consumption, it is noted that
until the first half of 2023, the significant decrease in consumption observed in 2022 continued, as a result of the
general economic climate that prevailed, following the decrease in the economic situation of households and the
expectations that were formed as a result of the ongoing revaluations in food and other basic necessities. The
economic climate of price increases and the high cost of energy generally affected consumer behavior, and, by
extension, consumption patterns related to water use. High energy costs have contributed to reduced water demand
during the winter months. However, despite the limited water consumption volume in the first half of the year - the
lowest in the last twenty years - the consumption level (WTPs) for the year showed a slight increase, remaining close
to the five-year average for 2018-2022, as water consumption was favored by the prolonged high temperatures
during the summer period of the year.
Although total consumption remained at the same level, invoiced consumption decreased by -5.6%, resulting in an
increase in non-invoiced consumption. Non-invoiced consumption is the difference between total and invoiced (now
free of charge) consumption. The percentage of non-invoiced consumption is the ratio of non-invoiced consumption
in the Internal Water Supply System of EYDAP SA (EWSS), to the volume of water at the exit of the Water Treatment
Units. The annual percentage of non-invoiced consumption in EWSS for the year 2023 was 25.1%, as a consequence
of the decrease in invoiced consumption, compared to 21.1% of the corresponding previous twelve months in 2022.
However, on a two-year basis, the percentage of non-invoiced consumption shows an improvement (lower).
Specifically, for the 2022-2023 period, the rate was 23.1% compared to 24.5% for the previous 2021-2022 period.
The total consumption

The decrease of -5.6% in invoiced consumption, corresponding to 17.3 million cubic meters, is mainly due to the
General Tariff, which showed a decrease of -7.0%, corresponding to 14.0 million cubic meters. The decrease in
invoiced consumption of the General Tariff category, despite the stability of the total, is due to the increased level
of invoiced consumption and number of bills issued in the first quarter of the previous fiscal year 2022, due to the
gradual normalization of the issuance and distribution of water bills, following the restoration of the suspension
effect resulting from the inability to identify a postal service provider, which lasted until November 15, 2021.
The decrease in the quantities of invoiced consumption of the Other Invoices over time is due to the reduction of
the water supply aid for the areas of the Municipality of Oropos, as well as to the interruption of other water supplies
of unpurified water, pursuant to the relevant contract with the Greek State. The reduction in the invoiced
consumption of the Other Invoices for the year 2023, compared to the previous year, corresponds to a quantity of
3.7 million cubic meters of water. It is noted that in the previous year, the invoiced consumption of the Other Invoices
of undifferentiated water, except those related to the enhancement of the water supply of the areas of the
Municipality of Oropos, was implemented on behalf of the Public Sector (EPEYDAP), in order to facilitate the smooth
transition management of the invoicing procedures. The reported invoicing of other water supplies of unpurified
water of the previous year 2022 (outside the Municipality of Oropos), corresponds to approximately 1.1 million cubic
meters.
There was also a decrease in the invoiced consumption of the Public Sector-Local Authorities category by -3.3%,
corresponding to 0.6 million cubic meters, returning to the levels of 2021.
On the contrary, the category of Local Authority Network Upgrade, which represents the second largest customer
category, showed an increase, which amounted to +1.3%, corresponding to 0.8 million cubic meters. The suspension
of distribution and consequently the suspension of invoicing, which affected the General Tariff category, did not
have an impact on the Local Authority Network Upgrade category, whose final consumers, supplied by the local
authority networks, showed similar consumption behaviour to the general consumers, with a slight increase in water
demand during the summer period.
The Industrial - Professional Tariff category also showed an increase of +0.7%, corresponding to 0.2 million cubic
meters. Hellenic Petroleum's consumption, which represents 40% of the total consumption of the Industrial-
Professional Tariff, remained stable at the consumption level of the year 2022, which is at the maximum
consumption level observed over time.
The following table presents the development of the invoiced revenues from water sales, for the main categories

is mainly due to a -6.0% decrease in revenues from the main category, which is the General Tariff (domestic). The
decrease in the General Tariff corresponds to an amount of € 9.4 million.

The decrease in invoiced revenues from the sale of water and right-of-use sewerage by -4.8% (€ 15.8 million) is a
result of the decrease in revenues from the General Tariff category, which constitutes 73% of the total invoiced
revenues of the year.
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 per cubic meter of water. The following table presents the relative allocation (%) of the
invoiced quantity of General Tariff water, in relation to the invoicing scales.

The 1
st
Scale corresponds to the lowest selling price of the General tariff per cubic meter of water and the quantity
of the first cubic meters of consumption of the water supply invoices. The 2
nd
Scale corresponds to the next highest
level of sales price and the amount of cubic meters of water consumption in the water supply invoices, and so on
for the following tiers.
The 1
st
Scale has increased its share of consumption in the General Tariff category over time from 48.6% in 2021 to
50.4% in 2022 and 51.1% in 2023, with an average annual growth rate of +2.5% per year from 2021 to 2023. The 2
nd
Scale, in contrast, decreased over time from 44.4% in 2021 to 42.7% in 2022 and to 41.9% in the year 2023, with an
average percentage share decrease rate of -2.9% per annum. The 5
th
Scale, which has the highest sales price and
corresponds to a quantity of cubic meters exceeding the highest consumption threshold, increased its share over
time from 3.2% in 2021 to 3.3% in 2022 and to 3.6% in the year 2023, with an average percentage share increase
rate of +6.1% per year.

contract in accordance with par. 2."
In article 34 of Law 5037/2023, it is defined that: "By joint decision of the Ministers of Environment and Energy,
Finance, Interior and Rural Development and Food, following the opinion of the Advisory Committee of paragraph
3 of article 4 and a recommendation of R.A.W.E.W.to the Commission, the general rules for costing and invoicing
water services, the measures to improve them, as well as the procedures and the method of recovering the cost of
water services in the various uses, are determined, according to par. 1 of the present and the p.d. 51/2007 ."
It is also defined that: "To determine the general rules for costing and pricing of water services, the principle of cost
recovery, including environmental and at the level of natural resources, is taken into account, as well as the
economic analysis carried out in accordance with par. 3 and the principle "the polluter pays".
The passing of Law 5037/2023 " Renaming the Energy Regulatory Authority to the Waste, Energy and Water
Regulatory Authority and expanding its scope with responsibilities over water services and urban waste
management, strengthening 34
the water policy - Modernizing the legislation on the use and electricity production from renewable sources through
the integration of EU Directives 2018/2001 and 2019/944 - More specific provisions on renewable energies and
environmental protection ", as well as the staffing of the Authority reduces the regulatory risk. The new expanded
regulatory authority (R.A.W.E.W.) has started its operation and a vice-president of the water sector has already
been appointed.
In September 2023, the no. 119/2023 decision of R.A.W.E.W. (Government Gazette 5408/Β΄/11-9-2023) was
published, which approves the Organization of the Regulatory Authority, regarding the responsibilities of its
Departments and Services.
Decisions of the Tripartite Compliance Council of the CoS
On March 20, 2023, the 7 & 8/2023 decisions of the Tripartite Compliance Council of the Council of State were
published, by which the Council of State ruled that the executive and legislative power, with articles 114 and 115 of
Law 4964/2022 ( mentioned above), did not comply with the decisions of the General Assembly of CoS 190 &
191/2022, which ruled the unconstitutionality of the transfer of the shares of EYDAP and EYATH from the State to
the HCAP and ordered compliance by the Ministry of Finance within 8 months and the re-transfer of the majority of
the shares of EYDAP from HCAP to the Greek State
Transfer of Majority shares of EYDAP from Growthfund to the Greek State
Article 64 of Law 5045/29/7/2023 (Transfer of EYDAP and EYATH shares from the Hellenic Holdings and Property
Company to the Greek State) provided that all of the Superfund's ownership shares in EYDAP and EYATH are
transferred to the Greek State. The transfer of 53,250,001 shares (50%+1 share) was completed on 3/8/2023.
Therefore, the total percentage of voting rights (directly and indirectly) controlled by the Greek State amounts to
65,319,740 (61.33%), of which the direct voting rights concern 53,250,001 common registered shares (50% + 1
share). and the indirect voting rights concern 12,069,739 (11.33%) common registered shares. The voting rights of
the 12,069,739 common registered shares (11.33%) relate to the percentage of share capital directly held by HRAFT
in EYDAP S.A. The Greek State universally controls 100% of the "Hellenic Holdings and Property Company S.A."
(Growthfund) which, in turn, by controlling 100% of the HRAFT, indirectly controls the voting rights in question.
The total percentage of participation (direct and indirect) of the Greek State did not change
Reception of municipal networks and WWTP
On 1.9.2023, EYDAP took over the municipal water supply and sewerage networks and the Waste Water
Treatment Plant of the city of Megara, the municipal sewerage network of the city of Nea Peramos and the
municipal water supply networks of the areas of Kinetta, Vlychada (Agios Panteleimonas), Nea Zoi, Kandyli ,
Koumindriou, Lakka, Agia Triada, Iremo Kymato and Pachi with their associated facilities.

The entire water supply network has a length of 270 km of pipelines and supplies water to 13,500 facilities.
Accordingly, the sewerage network of the city of Megara and the area of Nea Peramos has a total length of 96
km of pipelines, which includes approximately 6,600 constructed external branches of properties.
The WWTP Megaron receives sewage through a network of sewage collectors from the city of Megaron and
Nea Peramos as well as domestic sewage from areas that lack a sewerage network.
The capacity of the constructed facility is 43,330 (I.P.) and the average daily design flow of incoming
wastewater is 8,000 m3/d. According to the agency's records, in 2023, it treated an average of 1,900m3/d of
municipal wastewater and 90m3/d of sewage.
The treated wastewater is disposed of by an underwater pipeline in the Saronic Gulf sea area, west of the
Hersonissos of Ag. Triada at the "Almyres" location and at a depth of 30 m while the stabilized dewatered
sludge, since EYDAP took over the installation, is transported to the WWTP of Psittalia for thermal drying.
The average daily design flow of incoming wastewater is 8,000 m 3 / d .
Secondary treatment with nitrogen removal and disinfection is carried out at WWTP Megaron.
In 2023, it treated an average of 1,900 m 3/ d of municipal wastewater and 90 m 3/ d of sewage.
In mid-December 2023, the management and operation of the Koropi-Peania Wastewater Treatment Center
was handed over to EYDAP.
The facility has the capacity to treat wastewater equivalent to a population equal to 99,486 i.c.
In 2023, it treated an average of 1,750 m3/d of municipal wastewater.
In the already licensed project, the waste from the following areas is or will be directed:
• Municipality of Paiana as a whole, including BIO.PA. Peanias.
• The city of Koropi and the settlement of Karellas of the Municipality of Koropia, including the BIO.PA Koropi
and Karellas and the wholesale area of Koropi.
• The areas south of the Western Regional Avenue Ymittos of the Municipality of Pallini.
• The settlement of Hamolias in the Municipality of Markopoulos - Mesogaia.
Expansion projects of the WWTP of Koropi-Peania are planned, concerning a future new treatment line (2nd
treatment line) to accommodate the additional hydraulic and pollutant load of the sewage from the coastal
areas of the Municipality of Saronikos & Kropias.
The facility carries out secondary treatment with nitrogen and phosphorus removal and disinfection. The
treated wastewater is disposed of by a submarine disposal pipeline in the sea area of Hamolia in the South
Euboean Gulf through a tunnel.
Signing of an Agreement between the Municipality of Athens and EYDAP
On February 8, 2023, a program agreement was signed between EYDAP and the Municipality of Athens, according
to which it is foreseen that EYDAP will proceed with the construction of pipelines of the secondary definitive
sewerage network, either to replace old municipal pipelines, or to complete the network in Municipality of Athens,
as well as in the construction of the private connections of the properties with the central pipelines.
In practical terms, this means for citizens that applications for connection to the sewerage network will now be
submitted directly to EYDAP, while the waiting time for their service will be reduced from the current average of 2
years to just 3 months.
At the same time, with the implementation of this new agreement, it is planned to reduce the response time to
emergency breaks and breakdowns caused by the age of the network, thus eliminating even the slightest possibility
of causing a risk to public health.

Projects of Eastern Attica
Aiming at environmental protection, sustainable development, public health protection and the definitive
solution to the problem of disposal of urban wastewater in the Eastern Attica region, EYDAP included the
implementation of wastewater projects in the region among its operational goals.
EYDAP's planning for these important sewage projects aims both at the integrated management of the area's
wastewater and at the reuse of treated effluents to ensure maximum environmental benefit.
In this direction, the Waste Water Treatment Centers-WWTP to be constructed have been designed to operate
with state-of-the-art technology, ensuring the possibility of re-using the treated effluents, in full harmony with
the current institutional framework for re-use.
An Environmental Awareness and Information Center will operate at the WWTP facilities of the Municipalities
of Rafina-Pikermio and Spata-Artemidos, where pilot application programs will be implemented for the optimal
utilization of reclaimed water as well as information and education actions of an environmental nature.
The planning for the construction and operation of integrated wastewater management systems in Eastern
Attica includes projects in the areas of the Municipalities of Rafina-Pikermio, Spata-Artemida, Marathon, Pallini
Peania, Saroniko, Kropia and Oropou.
Eastern Attica projects investment plan
Ten-year plan 2022 = €794,046 thousand
Ten-year plan 2023 = €891,262 thousand
The ten-year investment plan for the year 2023 appears higher than 2022.
The variance comes primarily from the more conservative estimates made for expected discounts during the
bidding process for construction contracts.
In the contracts of the contracts there are no notable deviations in the contractual economic object.
Regarding the progress of the projects:
Regarding the schedule of the contractors
There are delays arising from the complex environment internationally/economic crisis/war in Ukraine,
material price increases, increased energy costs, lack of resources/reduced supply of available workshops at
acceptable costs, uncharted utility networks, increased rates of rocky terrain, etc.
An important factor in time deviations is also the implementation of the projects in areas of increased
archaeological interest (the entire area of eastern Attica).
Based on the knowledge gained so far, it seems that the claims of the contractors are expected to be important
during the development of the projects and until their completion.
Regarding the planning of EYDAP
Possible deviations in the initial planning of the contractors have been taken into account and the projects
have been planned accordingly. ΄
The continuation of co-financing by the NSRF during the Program Period 2021-2027 has been ensured. At the
end of this period, the assessment of the completion and operation of the projects is placed.
Absorption-Progress % of the total subject of contracts in progress
In the total of contracts implemented in Eastern Attica with a contractual economic object of 142 million euros,
the implemented object amounts to approximately 27% of the total.
Progress based on approved contractors schedule
Projected progress based on approved timetables at the end of 2023 = 51.2%
Evolution of East Attica Projects in 2023
In 2023, significant progress was achieved in the implementation of sewage drainage projects in Eastern Attica.

of Attica until 2040, serves 40% of the population of the Greek territory.
As the largest company providing water and sewage services in Greece and one of the largest in Europe, it
consistently, responsibly and sensitively ensures that it provides excellent quality water alongside modern and
uninterrupted sewage and biological cleaning services to the population of Attica, while at the same time ensuring
the natural habitat. EYDAP ranks 1st in terms of water quality among 180 countries worldwide, according to Yale
University's Environmental Performance Index (EPI).
Having as its primary objective the best possible service to its customers, as well as the efficient management of
water, its high level of expertise guarantees the coverage of the needs of the population served and the efficiency
of the use of resources.

investment program compared to 2022. All its important financial figures showed a significant improvement
compared to 2022.
Regarding the Company's projected course in 2024, the Company expects the formation of the new tariff and the
full operation of the Regulatory Authority for Waste, Energy and Water (R.A.W.E.W), while at the same time
continuing its important investment project mainly in Eastern Attica.
With regard to the formulation of the new tariff, EYDAP expects the issuance of the new JMD which will replace the
decision of the inter-ministerial National Water Committee No. 135275/19.05.2017, annulled by the Council of State,
on water pricing rules. After the issuance of the MOU, the Company will propose to the Ministry of Environment and
Energy, since the ERA is not yet fully operational, the new tariff based on the allowed income.
Regarding the formulation of the new tariff, EYDAP is awaiting the issuance of the new which will replace the decision
of the inter-ministerial National Water Commission no. After the issuance of the MOU, the Company will propose to
the Ministry of Environment and Energy, since the ERA is not yet fully operational, the new tariff based on the
allowed income.
The stable regulated business environment that is being formed is the basis for the further development of the
Company through its investment plan and transformation.
The Company has placed particular emphasis on strengthening the ESG strategy it follows. To this end, it has
established measurable indicators for the environment, society and good governance, based on internationally
recognized standards, which are systematically monitored and for which improvement actions have been developed
linked to the strategic tripartite of Safety, Efficiency, Development. The clear objective of the Company's strategy is
to reduce our carbon footprint and to make a substantial contribution to strengthening the resilience of its
infrastructure and the societies in which it operates and develops, as well as to strengthening its adaptive capacity
against the risks and natural disasters that result from climate change. EYDAP aims to achieve zero carbon water by
2030, which will make the company largely independent of the energy market.
PRINCIPAL RISKS & UNCERTAINTIES
CAPITAL MANAGEMENT
The Company manages its capital in such a way as to fulfill its purposes, as referred to in paragraph 4a of article 1 of
Law 2744/99. Also, in accordance with paragraph 8 of the same article, it is prohibited to create a real right over its
immovable fixed assets, which are used for the exercise of its activities related to the provision of water supply and
sewerage services. It is noted that according to article 5 of the same law, the forced execution of EYDAP's assets that
are used for the exercise of its activities related to the provision of water supply and sewerage services is not
permitted.
The Company currently has no long-term or short-term debt obligations. After its listing on the stock exchange in
2000 and until 2013, the Company had mainly engaged in short-term borrowing, in order to meet its operational
obligations due to the non-payment of water supply bills by some OTAs and other public bodies.
The Company takes care to maintain a sufficient amount of funds in order to serve its purposes by applying the
appropriate dividend policy.

The Revenue & Claims Management Department and the Special Clients Management Department constantly check
the claims from the Company's customers, either individually or by group (invoice codes, customer categories) and
integrate this information into the credit control procedures.
In order to deal with the credit risk, the Forced Collections Service of the Revenue & Claims Management Directorate
examines on a continuous basis and settles through the courts (ND 356/1974 "Public Revenue Collection Code")
overdue debts to be collected from water abstraction, usage rights and connection rights properties from individuals
and municipalities.
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 considered significant. The credit risk is managed by concentrating the largest part
of the Company's reserves in the Bank of Greece (about 60%) and by limiting the exposure to the other Greek credit
institutions (mainly Systemic banks).
None of the financial assets are secured by a mortgage or other form of credit security.
Accordingly, the Company has not assigned financial instruments of the Asset to third parties as a form of guarantee.
(2) Liquidity risk
Liquidity risk is managed by maintaining adequate cash reserves and securing bank credits for use. There is no
liquidity risk due to the existence of significant cash reserves capable of covering current operational and investment
needs.
The table below analyzes the Company's financial obligations, classified by relevant grouped maturity dates, which

(3) Market Risk
Market risk is related to the Company's equity portfolio, which is a long-term, strategic investment and is therefore
limited to predetermined position limits (Position Limits).
(4) Unsafe water supply of Attica due to failure of external aqueducts
EYDAP provides safe and uninterrupted water supply services by treating raw water supplied by the Greek State.
According to Article 7 "Obligation to Supply Raw Water" of the current contract "The State is obliged throughout the
Contract Period to supply the Beneficiary with Raw Water in accordance with the terms of this Contract and in any
case based on the criteria set out in Articles 8 ( Quantitative Characteristics) and 9 (Qualitative Characteristics) of
this Agreement."
Therefore, in case of failure to supply EYDAP with raw water, the financial loss is borne by the Greek State.
EYDAP recognized and assessed the risk of unsafe water supply to Attica due to failure of the external water supply
system in the unifying aqueduct, which is owned by the State. In June 2023, the tripartite signing of the Addendum
to the 2.2.2022 Contract between the Greek State, and the companies "Etyria Pagion EYDAP" and "EYDAP" was
successfully completed. SA". The subject of the agreement is the execution of works on the closed Union Aqueduct
Mornos - Marathona, Kleidi - Dafnoula Section. With this agreement, the implementation of an important project to
upgrade the External Water Supply System of Attica is promoted. The specific projects, of which the first has already
been announced, will shield the secure water supply against very high risks of failure in the union aqueduct.
At the same time, the necessary control mechanisms that will ensure the uninterrupted supply of quality water to
EYDAP in extreme weather conditions along the entire length and facilities of the EWSS have been identified and are
the subject of discussion with all those involved.
(5) Understaffing of organizational units
The understaffing of EYDAP arises as a result of the long-term limitations of adequate recruitment through Supreme
Council for Civil Personnel Selection (ASEP) and threatens the implementation of the Company's strategic plan. The
Company assessed the risks of understaffing by recognizing the average age of its staff, the requirements for the
transfer of know-how and experience, the difficulty in formulating a succession plan in critical positions necessary
for the Company's business continuity and developed a human resources management model for the next decade,
incorporating all necessary actions of adequate and appropriate staffing. Ways of recruiting sufficient permanent
staff in a timely manner that will mitigate the risk of dependence on external partners are being explored.
(6) Safeguarding and protection of facilities
The Company manages the risks related to the vulnerability of all facilities and the protection of security by dealing
with the threats that are likely to create problems and the weaknesses of the facilities. It studies and implements
modern systems of security, fire safety and surveillance of buildings and facilities and competently trains the staff
with the aim of incorporating the desired modifications and improvements. It applies modern technologies in
shielding against threats such as floods, earthquakes, fires, external factors, power outages, communication
interruptions, unavailability of personnel, malicious acts.
(7) Water scarcity
To manage the risk of water shortages, control mechanisms are applied to ensure sufficient supply of the Water
Treatment Units with raw water, in cases where the scheduled inflows will be subject to insufficient flow. According
to the updated water resources management plan of Athens, prepared by the Civil Engineering department of the
E.M.P. in cooperation with EYDAP, based on the existing data of the reserves, around the middle of July 2024, the
use of the Materials sector will be required with the operation of the Mavrosouvala wells, with a daily flow rate of
80,000 m
3
and pumping stations of the Materials sector, with a daily flow rate of up to 150,000 m
3
.
In the event that the reserves of the Evinos-Mornos system continue to decline, it is planned to:
a) to increase the pumping of the Materials sector,
b) to activate the boreholes of the Middle River of Boeotian Kifiss which, through the Union Aqueduct of Distomo,
feed the Mornos Aqueduct with a daily discharge capacity of 150,000 m

The evaluation of the underground aquifer in the Vasilikon-Parori drilling area has been launched and maintenance
is being carried out on the Ylikis aqueduct, the floating and other pumping stations of the sector.
(8) Cybersecurity
EYDAP has set as a priority its shielding through an organized cyber security framework, always harmonized with the
current legislative provisions. In this context, he proceeded to capture a risk profile for the upgrade of security
measures, as well as a study of the implementation of individual security policies and procedures, based on
international standards and methodologies. Developed a business continuity & recovery plan for the Company's
information systems from eventual disaster. It also created the required cooperation framework, on the one hand,
for the productive use of identified vulnerabilities on recorded activities, where personal data processing is
identified, and on the other hand, for the targeted creation of clear procedures and policy in the event of a violation
incident.
The control mechanisms available to the company to detect such risks/incidents include tools for training and raising
awareness of all personnel on cyber security issues, for collecting information critical to the security of the Company
and for the early detection of threats from external sources at different levels of the Web and for the monitoring
and evaluation regarding the course of the security level of the Company's web resources in relation to the
vulnerabilities as well as the threats identified using Open Threat Intelligence techniques.
In the year 2023, immediate response services were ensured in case of detection of a cyber security incident, with
participation in the financed Cyber Security Support Service Action of ENISA (European Union Agency for
Cybersecurity) through the National Cyber Security Authority for the FEBY of the EU member states.
(9) Risks from Climate Change
EYDAP approaches climate risks as an opportunity to transition to a more sustainable future with low carbon
emissions and implements mitigation measures:
It has integrated into its strategy the improvement of energy efficiency and the reduction of the carbon
footprint
Implements water demand management and leakage reduction programs for rational and sustainable
management of water resources. The old water meters are replaced with new "smart" water meters of
state-of-the-art technology. The network is being cleaned up and old pipelines are being replaced with new
pipelines made of sophisticated materials compatible with the natural environment.
It applies circular economy practices. Routes WWTP wastewater reuse projects of East Attica for irrigation
of peri-urban greenery, industrial and municipal purposes.
It approaches the use of technologies to improve the performance of water and wastewater treatment
plants
It highlights alternative water resources for irrigation use such as the exploitation and promotion of the
Hadrian Aqueduct
It takes care of every possible saving of energy and resources in all its activities and actively contributes to
the reduction of greenhouse gas emissions
It applies with zero tolerance European and Greek regulations and standards, new and existing
environmental specifications in the design of water supply and drainage projects
It chooses materials and machines with modern environmental standards. It monitors and optimizes the
circularity of the materials used. It seeks that products and materials (including raw materials) remain in
the life cycle for as long as possible, and that waste is treated as secondary raw materials that can be
recycled for processing and reuse (circular economy).
Electric vehicles - Seeks to replace part of its fleet with electric vehicles as far as possible to contribute to
low greenhouse gas emissions
It upgrades and modernizes its buildings and facilities with new building materials and energy systems.
The Company takes care and plans emergency management scenarios that may arise due to climate risk. Recognizing
the way in which each of its organizational units operates, it has included in the risk register of the Business Risk
Management Framework the risks against which it must be shielded for its effective response. Regarding our last

year's commitment to implement the TCFD recommendations, due to the incorporation of said recommendations
into the new IFRS/ISSB international standards, the Group is in the process of revising the adoption approach
combined with the ESRS standards.
(10) Energy crisis
EYDAP has included in its strategy approaches to optimize the energy utilization of all processing products and
shields the company against any effect from fluctuations in energy prices, which have been proven to affect its
operating costs and profitability. The company is involved in a number of projects that focus on reducing energy
consumption and recycling as much as possible. To mitigate in a future phase the risk of increasing energy costs, it
strategically focuses on new technologies for sludge management and energy utilization in the management of
processing products.
It aims at a greater penetration of RES based on the best available technologies and practices to avoid impacts on
the natural environment.
It promotes electrification while striving to improve the carbon footprint of buildings and infrastructure through
building modernization and implementing energy saving approaches.
As part of EYDAP SA's strategy to achieve a zero carbon footprint by 2030:
a tender was announced for the supply of 16 electric two-wheelers, the time lease of 53 electric vehicles
for 48 months and the supply-installation of their recharging infrastructure (H/O chargers and management
software). In December 2023, a decision of temporary contractors was issued.

legislation, are reflected in the Articles of Association, the Operating Regulations, the Greek Code of Corporate
Governance 2021, the Code of Ethics and Professional Conduct as well as in other Regulations and Policies of the

A. Corporate Governance Code
B. Deviations from the Corporate Governance Code and Explanations
C. Board of Directors and Committees of the Board of Directors - Other administrative, management or supervisory
bodies or committees
D. General Assembly & Shareholders' Rights
E. Internal Control System
F. Reference to the information provided in Article 10 of Directive 2004/25/EC
A. Corporate Governance Code
EYDAP with the no. 20905/7.7.2021 Decision of its Board of Directors adopted and implemented in accordance with
Article 17 of Law 4706/2020 and No. 2/905/3.3.2021 Decision of the Board of Directors of the Capital Market
Commission on the Greek Corporate Governance Code for companies with securities listed on the stock market

as a national body of recognized prestige by the Board of Directors of the Capital Market Commission during its

meeting.
The Company in the year 2023 complied with the provisions (special practices) of the GCGC governed by the
"Compliance or Explanation" principle with the deviations mentioned below in paragraph B.
The Company intends to adopt appropriate practices in order to minimize the existing deviations in relation to the
provisions of the GCGC.
B. Deviations from the Corporate Governance Code and Explanations
At the time of this publication, deviations from the GCGC constitute the following:
Principles of GCGC
Explanation of Deviation and measures to
minimize deviation risks
Role and responsibilities of the Board of
Directors
Composition of the Board Appointment of
vice-chairman or senior independent
member in case the Chairman of the Board
is not an independent member (Special
Practice 2.2.21)
According to article 12 of the Company's current
Articles of Association, the roles of Chairman and
CEO may coincide with the same person. In this case,
the Board of Directors appoints an independent
Vice-Chairman, from among its independent
members. The above statutory regulation was
introduced following the adoption of the special
practice 3.3 of the Greek Corporate Governance
Code for Listed Companies issued in 2013 by the
ESSED according to which: "The Board of Directors
should appoint an independent Vice-Chairman, from
among its independent members, in the cases he has
chosen:
to assign to the same person the duties of
Chairman and CEO,
to appoint an executive
Chairman."
Taking into account the above but also that:
in compliance with article 8 of Law 4706/2020, the
current Chairman of the Board is a non-executive
member, therefore the qualities of Chairman and
CEO do not coincide with the same person,
the outgoing Chairman of the Board of Directors,
whose term of office ended on 12
September
2023,
had been assessed by the Board of Directors with
the assistance of a third independent consultant as
a person of high acceptance and particularly
effective in the exercise of her duties,
September 2023 and has already been evaluated
in accordance with article 49
A
, is imminent within
the current financial year of the Rules of Procedure
of the Parliament by decision of the Committee on
Public Enterprises, Banks, Public Benefit
Organizations and Social Security Agencies as well
as
that the work of the Board of Directors is always
conducted in the context of a constructive
dialogue based on the interests of all interested
parties and the Chairman seeks and encourages
the participation of all its members,

Graphics
47
this discrepancy is estimated to have no effect on
the operation and effectiveness of the Company's
Board of Directors nor on the transparency and
effective supervision of the executive members. The
need to amend article 12 of the current Statute will
be evaluated in the context of an upcoming
amendment of the Statute that will take place to
harmonize with the provisions of Laws 5037/2023
and 5045/2023.
Succession of the Board of Directors
Board member succession plan gradual
replacement of board members (Special
Practices 2.3.1 - 2.3.3)
Given the special regime that governs the Company
regarding the election of the majority of the
members of the Board of Directors by the Greek
State (Law 5045/2023 in conjunction with the
decision no. of the Three-Member CoS Compliance
Board), there is currently no procedure for the
advance and on a permanent basis activation her
Commission Fees and Nominations regarding the
succession of the members of the Board of
Directors. In the event that there is a need to replace
one or more members of the Board appointed by
the majority shareholder, the Remuneration and
Nominations Committee is activated in order for the
Greek State to initiate the process to find suitable
candidates for new members in accordance with the
Company's Nominations Policy.
With regard to the gradual replacement of Board
members, the practice followed by the Greek State,
which as the majority shareholder elects the
majority of Board members, is that the end of the
term of office of the outgoing members is also the
beginning of the term of the new Board members.
This practice has been successfully implemented
without creating an issue of lack of management.
There is, however, an express statutory provision
(article 11 par. 6) regarding the possibility of the
General Assembly to decide on departmental
renewal of the Board of Directors and/or successive
expirations of the terms of office of its members.
Board members' remuneration
Malus & Clawback provisions in contracts of
executive members (Special Practice 2.4.14)
The Remuneration Policy for the members of the
Board of Directors, which was approved by decision
of the 38th Ordinary
General Assembly which took
place on 26.6.2020 and last revised by a decision of
the 41st Ordinary General Assembly which took
place on 6.9.2023 includes malus & clawback
provisions regarding with the variable
remuneration of the executive members. The
provisions in question are not included
independently as terms in the indefinite-term
contract of the currently sole executive member of
the Board of Directors, already drawn up from the
year 2020, however there is an explicit provision in
it regarding the application of the currently

Graphics
48
applicable Remuneration Policy. And in the current
Remuneration Policy there is an explicit provision
(par. 4.2.3) regarding the right of the Company to
use all legal means to claim the return of paid
amounts (in whole or in part) in cases of violation of
regulations or procedures, non-compliance with the
standards of fitness and reliability or other equally
serious cause which led to significant losses.
Therefore, there is no substantive question of
deviation from provision 2.4.14 of the GCGC and it
is estimated that there is no specific risk for the
interests of the Company and all interested parties.

effectiveness of the EES dated 29/03/2023 is that from the work carried out and the evidence obtained regarding
the assessment of the adequacy and effectiveness of the Company's EMS, no weaknesses were identified that could
be considered material in the Company's EMS according to the Regulatory Framework, with the exception of the
finding of insufficient gender representation on the Board of Directors, as the percentage of female members of the
Board of Directors short of 25% of all members of the Board of Directors (2 of the 13 members of the Board of
Directors are women) in deviation from the relevant requirement of the law for sufficient representation by gender.

Strategy Analysis
The vision of zero burden of the ecosystem is the driving force behind all company’s activities and planning.
The new fleet, the installation of photovoltaics and the optimization of pump stations efficiency are the first line of
actions that will reduce the energy cost and greenhouse gas emissions. In the same axis, it is planned to increase the
biogas production from wastewater treatment. Our goal is energy neutrality by 2030.
In full response to current legislative framework regarding water and effluent, the Company is in preparation of
compliance with the upcoming new European requirements, regarding energy neutrality and further improvement
of effluent outflow quality of Wastewater Treatment Centers. At the same time, the Company is designing an
intergraded system for the reuse of water and other processing by-products in Attica and a risk management plan
for the possibility of prolongation of drought phenomena.
The major part of EYDAP investment program is currently dedicated to development projects that have a positive
and multiple impact on local community and the environment. Through wastewater management and water reuse
infrastructure in East Attica, that constitute the Company’s biggest development project, we upgrade the quality of
life of over 400,000 residents and contribute to the protection of our water sources, of the marine environment and
of the underground aquifer.
However, network shielding projects, pipeline maintenance and replacement projects as well as the Company’s
digital transformation are not missing from the overall operational planning. Starting in 2026, smart meters and new
digital management systems are expected to reduce operational cost and progressively contribute to the avoidance
of the waste of the precious resource and overall improve consumer’s experience.

Policies, such as those regulating corruption and bribery issues as well as conflicts of interest, frame the way EYDAP
operates internally and manages its supply chain. Emphasis is placed on labour and human rights protection, in a
context of meritocracy and transparency that promotes equality and safe work environment
A great part of Strategy’s monitoring performance indicators are in harmony with modern ESG standards and the
Company has a reward system in order to achieve coordination of efforts and participation in reaching a collective
result. The Company has taken actions to adapt to the regulatory requirements of the new independent water
regulatory authority (RAEEY).
The Directorate of Strategy and Innovation, in conjunction with the Committee of the Board of Directors for Strategy,
Innovation and Sustainable Development ensure that in strategy planning, in addition to the material issues as
derived from the materiality analysis, European and national trends and policies and technology development are
taken into consideration. With this target, EYDAP actively participates in the largest relevant European networks and
national consultations.
Given the Company’s extended investment plan to achieve the above, our concern is clean water for everyone at a
fair price through a sustainable management and strategy financing model.

1. ENVIRONMENT
1.1 SUSTAINABLE MANAGEMENT OF NATURAL RESOURCES/ WATER SUPPLY RESOURCES material topic
The main axis of sustainable development of EYDAP 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 with a high standard of know-how i.e. the exploitation of
natural resources without burdening the environment but caring for and protecting it.
Our impacts
1. RESERVOIR SUSTAINABLE MANAGEMENT
EYDAP SA supplies raw water:
from surface water resources owned by the Greek State,
The raw water supplied by the Greek State to EYDAP SA (at the Water Treatment Plants), comes from surface water
resources of the Marathon, Ylikis, Mornos and Evinos drainage basins. Of the reservoirs, only that of Ylikis is natural
(lake ), while the rest have been created with the construction of dams in suitable places on the riverbed of the
rivers Haradros (Marathonas dam), Evinos and Mornos.
from underground water resources owned by EYDAP SA and the Greek State.
The water of the underground water resources can be utilized depending on their availability and their usage policy,
with the function:
20 boreholes in Mavrosouvala owned by EYDAP SA, with a total annual pumping capacity of approximately
41 million m
3
of water/year,
68 boreholes owned by the Greek State, with a total annual pumping capacity of approximately 138 million
m
3
of water/year.
Based on the current operating conditions, EYDAP's water intake sources can be separated as:
Main water sources : Mornos, Evinos.
Graphics
114
Auxiliary water sources : Marathon (for the supply of MEN Galatsiou) and Yliki (in emergency cases).
Backup water sources : underground water resources - boreholes.
The reservoirs are managed with the main objective of the quantitative and qualitative sustainability of the
resource.
EYDAP SA ensures the protection of reservoirs by:
the observance of strict legislation (Sanitary Decree A5/2280/1983 as in force) "for the protection of the waters
used for the water supply of the capital region from pollution and contamination" and of PD 51/2007 concerning
the definition of measures and procedures for the integrated water protection and management in compliance
with the provisions of Directive 2000/60/EC
control of projects and activities in the protection zones of the reservoir catchments
sample measurements regarding the water quality of the reservoirs.
The applied water resource management methods are characterized 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 Distribution of Withdrawal (in hm3) of water resources for the coverage of all water supply needs (EYDAP,
Municipalities, etc) for 2023 is analyzed as follows
The following distribution refers to the optimal management of water resources for the given year. Withdrawals
are measured at water intake sources with flow meters.
2023 withdrawals from reservoirs & boreholes
2. SUSTAINABLE WATER SUPPLY NETWORK & ASSETS MANAGEMENT (SMART GRID)
Guided by the Sustainability of the resource as well as the coverage of water supply needs, EYDAP manages water
demand developing leakage reduction programs (pressure management, water supply zones, immediate repair of
damages, etc).
In the context of transformation aiming at the modernization and optimization of network and assets management,
EYDAP is in the process of developing a “Smart Grid”. The Smart Grid regulates and controls production and
distribution of the resource and aims to the smart interconnection of consumers to production with the ultimate
goal of a more economical and safer network with reduced losses.

5. ADREIANIO AS WATER RESOURCE Pilot Program CULTURAL HIDRANT
The Adreianio Aqueduct is a unique multi-complex underground hydraulic and water drainage project. It passes
underground Attica, through one of the largest tunnels of the Roman era, from Parnitha to Kolonaki at a length of
23,7 km (the reinforcing aqueducts not included). It still carries water drained from the underground aquifer along
its whole length. The design, realization and its longitudinal operation makes it an important monument of ancient
hydraulic technology.
EYDAP constructs network for the use of the Adreianio Aqueducts in Chalandri, with the co-financing of EU (UIA
Cultural HID.R.A.N.T.). This is the first non-potable water network of EYDAP for the irrigation of 6 km of urban green.
This water will irrigate the surrounding area of 6 schools, 1 kindergarden and 17 parks/green areas and municipal
redevelopment as well as 45 private gardens. More than >10.000 m3 of drinking water will be saved annually and a
total amount of 45.000-90.000 m3 of water..
Total budget of European funding for Chalandri: 3.133.296 ευρώ
Monitoring of Adreianio Aqueduct Water
The control of the quantity and quality of Adreianiou water is planned to be done with a modern central digital
system. For this purpose, several on- line instruments are planned to be placed in the water tanks and in the under
construction network.
Regulatory Compliance-Adreianio
For irrigation water all specifications, controls and their periodicity, as dictated by the Greek legislation, will be
met to the fullest extent, in full harmony with the European Legislation.

1.2. PROTECTION OF ECOSYSTEMS material topic
1.2.1 PROTECTION OF MARINE ECOSYSTEM
Key concern of EYDAP is to preserve the good environmental status of the marine ecosystem. The Company, in the
context of its activities, takes all necessary measures to ensure its protection.
Our impacts
WWTPs Design & Operation
WWTPs, through the collection and treatment of urban wastewater, consist of key environmental infrastructures for
the protection of marine receptors. The treated effluent of the WWTPs discharge in the sea free of their pollutant
load at a rate of approximately 95%.
The operations at Psyttalia WWTP, beginning, in 1994, were a milestone in the improvement of the Saronic Gulf
marine ecosystem, which in previous years had dramatically downgraded due to discharge of untreated wastewater.
The treated effluents from the Psittaleia and Thriasio water treatment plants end up directly in the Saronikos and the
Elefsina Gulf respectively, while the Metamorfosi water treatment plant is discharged to Saronikos Gulf, through its
main receiver, Kifisos river.
The assessment by EYDAP of the ecological state of the marine ecosystem around the Psyttalia WWTP now also
focuses on pharmaceutical substances, within the framework of the ENVIROMED research program . The
information they will collect contributes to the company's preparation for the implementation of the upcoming new
European Directive on Wastewater Treatment. A pilot application of quaternary wastewater treatment will be
implemented in the Gulf of Elefsina, within the framework of the research project RHE - MEDIATION .
In 2023, EYDAP installed three fixed telemetry stations in the Kifissos River, which record and transmit in real time
the variation of parameters - indicators for possible pollution of this sensitive ecosystem.
In September 2023, EYDAP took over the Operation and Maintenance of the Sewage Treatment Center of Megara,
whose treated effluents are dicharged in the Saronic Gulf.
EYDAP, by designing and implementing a program to modernize its facilities, not only ensures compliance with the
effluent quality of WWTP, as provided by the DAEC, (Decision Approving Environmental conditions) but achieves even
better effluent quality.
PARTNERSHIPS WITH SCIENTIFIC BODIES AND DISCLOSURE OF THE WWTP’s PROPER FUCTIONING OUTCOMES TO
THE PUBLIC - HCMR
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 receiversand show improvement over time. In
addition, environmental monitoring is systematically carried out by competent state bodies (General Secretariat of
Natural Environment and Water of the Ministry of Environment and Energy, Region of Attica, Blue Flags Program).
The good quality of the coastal waters is also proven by the fact that almost all of the coasts, with a provision for
swimming, of the Saronic Gulf have received the "Blue Flag" (award).
The effective operation of WWTP’s is monitored and controlled, systematically both with on - line instruments and
with laboratory analyses, in the intermediate stages of processing and at their outlet. The results of the monitoring

During the reporting period, the Company has not identified any non-compliance with environmental
laws and/or regulations
However, it is clarified that the situation of the water receivers also depends on other factors, which are not within
the scope of the EYDAP's responsibilities
EAST ATTICA PROJECTS Marine Environmental Protection
Upon the operation of the projects is expected the marine environment to be protected, water quality and
swimming beaches to be upgraded.
EYDAP has contracted with the Hellenic Center for Marine Research (HCMR) to monitor the marine ecosystem of
the South Euboean Gulf in order to document its current state and assess the impact of the Wastewater Treatment
Plants.
Regarding the current situation of the region (2022-2023), the following are summarized:
The concentrations of dissolved oxygen, soluble organic carbon and other parameters were determined
at normal levels.
The stations in the examined area of the Euboean Gulf were in a GOOD trophic state (eutrophication index
E.I.)
The ecological quality ratio of chlorophyll shows that the stations are generally characterized from
"Moderate" to "High" Environmental Status .
The South Euboean ecosystem can be characterized as healthy and stable due to the presence of many
species and high biodiversity values.
Microbiological control: none of the faecal contamination indicator micro-organisms have been recorded
at levels indicating unfitness of waters in the South Euboean Gulf
It is deemed necessary to continue the monitoring program of the Southern Euboean Gulf in order to
assess the evolution of the ecosystem and the effect of the operation of the new WWTP in East Attica in
accordance with the obligations of the National and European legislation and the Decision Approving
Environmental conditions.
After the completion of the recording of the existing situation, HCMR will continue to monitor the marine ecosystem
during the operation of the new Wastewater Treatment Centers (WWTP’s) and the expected upgrade of the
ecosystem, due to the operation of the integrated wastewater management infrastructures
1.2.2 PROTECTION OF BIODIVERSITY
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.
Graphics

Our impacts
Due to the fact that human activities are strictly regulated, lakes are developing into significant wetland ecosystems
which support protected avifauna species, interesting fish fauna and unique lakeside vegetation.
The main role of EYDAP reservoirs is to store water for the water supply of the capital however they also constitute
significant wetlands:
The natural lake Yliki, 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 water supply system of Attica and an important
wetland.
The reservoir of Mornos and the reservoir of Evinos are important wetland ecosystems.
WATER FOR THE ECOSYSTEM - "ECOLOGICAL SUPPLY"
To maintain the continuity of wetland ecosystems, EYDAP SA investigated the possibility of maintaining "ecological
supply", in the river ecosystems downstream of the dams. Maintaining this minimum required flow is necessary
according to legislation, environmental conditions and modern international trends in environmental reservoirs
management.
EYDAP SA implemented a Technical Environmental Study for the Mornos and Marathon dam.
According to the Technical Environmental Study for the Marathon Dam, it was estimated that a flow rate of 25 l/sec
downstream of the dam is required to achieve the above mentioned purpose, which was implemented.
The river ecosystem downstream of the Mornos Dam is in good condition, due to continuous flow of surface water
in the river bed. EYDAP has completed the systematic monitoring of the ecological and chemical state of the river
ecosystem, implementing a three-year program of hydromorphological , physicochemical, biological and chemical
measurements, in accordance with the specifications of the Water Framework Directive 2000/60/EU and the Water
Management Plan YD04 which predicted the Technical and Environmental Study of the Mornos Dam. The above
monitoring indicated that the river ecosystem downstream of the Mornos dam is in good ecological and chemical
condition.
An “ecological flow” of 1m3/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.
EAST ATTICA projects Ecosystem upgrade
The collection and treatment of the urban wastewater of the settlements is an environmental infrastructure project
that protects the surface and coastal water ecosystems.
Especially in areas of protected wetlands of Natura 2000 areas such as the National Park of Schinias , Special
Ecological Assessment (SEA) studies are prepared in the context of the Environmental Impact Studies of the drainage
projects, with the aim of maintaining the ecological integrity of the areas and achieving the protection objectives (
SSCO ) of species and their habitats .

Carbon Footprint Calculation
The gases that have been measured are: a) carbon dioxide (CO2), b) methane (CH4) and c) nitrous oxide (N2O),
which are the main greenhouse gases and account for most of the emissions produced. In addition, HFCs are also
measured, which are among the ozone depleting substances (ODS). The other measurable greenhouse gases listed
in the Kyoto Protocol (NOx, SOx, PM) are not recorded because according to the initial carbon footprint reports
(years 2019-2020) they represent a very small percentage based on the Company's field of activity and in the official
platform of the Ministry of Environment and Energy, notified to us in October 2023, their calculation is not required.
The values used for the Global Warming Potentials (GWP) for carbon dioxide (CO2), methane (CH4) and nitrous oxide
(N2O) are 1, 28 and 265 respectively (IPCC Fifth Assessment Report (AR5)).
The methodology followed for the calculation of the carbon footprint of EYDAP is based on:
1. ISO 14064-1:2018 Greenhouse gases - Part 1: Specification with guidance at the organization level for
quantification and reporting of greenhouse gas emissions and removals.
2. Greenhouse Gas Protocol, WRI (GHG Protocol Corporate Accounting and Reporting Standard, Revised Edition).
In May 2023, EYDAP, in order to better depict the carbon footprint data, changed the calculation boundaries and
recalculated SCOPE 1, 2, 3, using with its own calculation tool and classifying the processes that take place within
the External Aqueduct System as indirect emissions of EYDAP, thus recording a deviation from the published data in
the Annual Report 2022. Subsequently, in October 2023, a calculation tool was posted by the Ministry of
Environment and Energy on the basis of which EYDAP recalculated the CO2 emissions for the year 2022. The
verification of the 2022 Carbon Footprint Report was performed by an external verifier and the agreed level of
assurance was set as reasonable.
Given the above, the reference year for the calculation of the carbon footprint of EYDAP S.A. is 2022, as defined in the Climate
Law 4936/2022 as the year of obligation to submit a verified report to the online database of N.E.C.C.A. which is supervised
by the Ministry of Environment and Energy. It is noted that since the 2022 Report onwards, methane (CH4) and nitrous oxide
(N2O) emissions from the use of biogas within the EYDAP facilities are included.

Modifications to Scope 1 and Scope 2 carbon footprint calculation of 2022.
In the year 2021
The calculation of the Carbon Footprint was based on the calculation tool of EYDAP
The External Aqueduct System was included in the total emissions of EYDAP as direct emissions (Scope 1)
Emissions from the biogas used on-site were not included, which emissions are calculated for the first time
since 2022.
For the year 2022 (reference year)
Scope 1 and Scope 2: Emissions were originally calculated based on the EYDAP calculation tool, and the
corresponding figures were provided in the non-financial report for 2022. Subsequently, in October 2023,
following the obligation to use the platform of the Ministry of Environment and Energy, SCOPE 1 and SCOPE 2
emissions were recalculated for the year 2022.
Graphics
123
Scope 3: There is no provision for the calculation of Scope 3 emissions in the calculation tool of the Ministry of
Environment and Energy, which remains optional. The calculation of Scope 3 emissions was carried through the
use of EYDAP S.A. calculation tool. It is noted that, since 2022, the External Aqueduct System is included in the
indirect emissions of SCOPE 3.
Distribution of equivalent emissions (tCO

From the processing of the data and the calculation of the carbon footprint of EYDAP for the year 2023, the following
results are obtained:
SCOPE 1 (Category 1):
In 2023, the equivalent emissions corresponding to SCOPE 1 amount to 149,628.77 tCO
2
e.
The processes taking place in the Wastewater Treatment Plants (fugitive emissions) (147,931.85 tCO2e), which are
direct emissions, have the largest contribution to GHGs emissions of EYDAP. Other emissions included SCOPE 1 are
the following:
Stationary combustion sources with natural gas: 203.95 tCO

SCOPE 2 (Category 2):
In 2023, the equivalent emissions corresponding to SCOPE 2 (electricity consumption location based) amount to
76,940.312 tCO
2
e.
Electricity consumption - location based reflects the average GHG emission intensity of the electricity network on
which the electricity consumption takes place, and grid weighted emission factor data are used to calculate
emissions. The electricity consumption of all EYDAP facilities is the second most important source of GHG emissions
in EYDAP. The largest indirect GHG emissions due to electricity consumption are observed:
At the Psyttalia WWTP where emissions amount to 33,052.40 tCO
2
e
At the Water Supply Network where emissions amount to 25,884.67 tCO

The Climate Law 4936/2022 (Government Gazette 105/Α΄/27-5-2022) defines the institutional framework for the
gradual reduction of anthropogenic greenhouse gas emissions with the aim of achieving climate neutrality in 2050
as well as adaptation to climate change. Essentially, this is the Road Map that the country will adopt in order to
achieve the goal of climate neutrality by 2050.
Since 2022, EYDAP has been obliged to submit its carbon footprint report on the online database of N.E.C.C.A.
which is supervised by the Ministry of Environment and Energy.
INCLUSION OF THE PSYTTALIA WASTEWATER TREATMENT PLANT IN THE GREENHOUSE GAS EMISSION
ALLOWANCE TRADING SCHEME (EU-ETS)
According to the legislation, the Psyttalia WWTP, has been included in the above system for more than a decade.
Every year, reports are drawn up and verified by an independent certified body and submitted to the competent
National Authority (Ministry of Environment and Energy), while the corresponding emission allowances for the year
in question are delivered (returned) to the relevant European Union Registry.
It should be noted that until 2022, biogas was considered as pure biomass under the EU-ETS (European Union
Emissions Trading Scheme) and therefore its combustion did not contribute to GHG emissions.
However, since 2023, there is a regulatory obligation to identify the non-biogenic (fossil) and biogenic carbon
fraction in biogas, which will result in GHG emissions from the combustion of biogas to be reported under the ETS.
Due to the objective difficulty in identifying the mineral and biogenic carbon fraction in biogas, a conservative
estimate is made by analysing the sludge, which results in increased emissions (total 10,535 tn). At the same time,
an accurate determination of emissions is sought by analysing the biogas itself.
Graphics
126
The graph below shows the annual emissions under the system in place until 2022 due to the use of natural gas
and oil.
Both in 2022 and much more so in 2023, gas and oil emissions are sharply reduced compared to previous years,
due to a number of targeted management options, namely:
Natural gas use reduction and its substitution with biogenic biogas produced on site from sludge
treatment.
Projects implementation through which the production of biogas increased.
The installation of an integrated automatic power and energy management system, which allows for the
most rational management of energy resources.
However, since 2023 and onwards the non-biogenic (fossil) emissions of biogas (i.e. the fraction of fossil carbon in
biogas) are also taken into account, therefore it is noted that an increase in biogas production implies an increase
in the emissions of the installation, but not to the same extent as through the natural gas that is substituted, which
is 100% of fossil origin. Since 2023 and onwards, the CO2 emission diagram will include the non-biogenic (fossil)
emissions of biogas.
1.3.2 ENERGY
At a time of intense economic and geopolitical crisis, the cost of energy as a key regulator of industrial processes has
created an unfavourable cost condition along the supply chain, with an impact on environmental and economic
sustainability.
The current energy crisis and the risks associated with it require a holistic approach. In order to strengthen its
corporate resilience and with a view to its environmental footprint, EYDAP has designed a specific Corporate Strategy
that aims to:
Energy saving in the production process
Production of energy from renewable energy sources (PV, SHPSs) at the company's facilities
Electricity supply contracts with 50% of electricity from green sources
Graphics
127
contributing to the achievement of the national objective of increasing the production of energy from Renewable
Energy Sources.
ENERGY PRODUCTION FROM RENEWABLE ENERGY SOURCES AT EYDAP S.A.
In the context of optimising its energy balance and the utilisation of renewable energy sources, EYDAP has
developed:
1. PHOTOVOLTAIC STATION OF ACHARNAI
The company installed a photovoltaic (PV) station with a capacity of 1.9712 MW at its premises in the Municipality
of Acharnai and it was put into operation on 03/10/2019. In 2023 (January - December), the energy production
amounted to 3,131,958 kWh, on the same level as in 2022.
2. SMALL HYDROELECTRIC POWER STATIONS (SHPSs)
Along the external aqueducts (External Aqueduct System) that transfer water from the reservoirs to the refineries,
small hydroelectric plants operate, which are owned by EYDAP and whose energy is sold from EYDAP S.A. and
compensated by the Renewable Energy Sources Operator & Guarantees of Origin (DAPEEP SA). The water from the
aqueducts is diverted to a side canal, where, with the operation of a hydro turbine, the hydraulic energy is converted
into mechanical energy and then, through a generator, into electricity. The water is then reintroduced into the main
aqueduct, where it continues to flow.
Specifically, the operating SHPSs are:
Elikonas SHPS with a power capacity of 650 kW
Evinos SHPS with a power capacity of 820 kW
Kithaironas SHPS with a power capacity of 1200 kW
Kirfi SHPS with a power capacity of 760 kW
Mandra SHPS with a power capacity of 630 kW
In 2023, the total energy production from the above SHPSs will amount to 19,154,888 KWh, approximately 1% higher
than in 2022 (18,972,099 kWh).
The energy produced by the SHPS is totally dependent on the range of the PPC (Public Power Corporation) grid
instabilities, as well as on the weather conditions and the resulting failures of the electromechanical equipment of
the plants.
3. SMALL HYDROELECTRIC POWER STATION IN THE PSYTTALIA WWTP
In Psyttalia, there is a small hydroelectric plant installed in the outflow pipeline (489 kW), operating since 2015,
whose own electricity production amounts to 2,154,998 kWh in 2023, 2,180,239 kWh in 2022, which is consumed
on-site by the Company. The variation of the electricity production from this plant in the outflow of the Psyttalia
WWTP is due to the annual variation of the wastewater flow rate.

4. BIOGAS
The biogas produced in the digesters of the Psyttalia WWTP is used as fuel:
In the thermal drying unit of the dehydrated sludge
In the boiler room of the digestion unit for heating the sludge
In the steam generating unit for steam production (for the thermal hydrolysis unit of the sludge).
In internal combustion engines for combined heat and power generation (CHP)
In regenerative thermal oxidizers (RTO) for the treatment of exhaust gas from the drying plant
At the Metamorphosis WWTP, the digester biogas is currently used only as thermal energy, but the installation of
a combined heat and power (CHP) generation plant is planned, in order to enable full use of the biogas produced.
The electricity produced at Psyttalia WWTP in the CHP/High-Efficiency CHP was 22,514 ΜWh (22.514 GWh ) in 2022
and 23,869 MWh (23.869 GWh ) in 2023.
The recovered thermal energy of the Psyttalia WWTP biogas in 2023 amounted to 130,000 MWh and the recovered
thermal energy of the Metamorphosis WWTP amounted to 2,745 MWh.

1.3.3 CLIMATE CHANGE MITIGATION STRATEGIES
ACTIONS AIMING TO DECREASE CARBON & ENERGY FOOTPRINT OF EYDAP S.A.
The Company, with environmental responsibility, is integrating transformation actions in its operations, aiming to
reduce its carbon footprint (Net Zero).
The Strategy for improving energy efficiency and reducing the carbon footprint by 2030 through 3 action axes, was
drawn up:
Α. Energy saving throughout the production process
Β. Energy production from renewable energy sources (PV, SHPSs) at the company's facilities
Γ. Electricity supply contracts
Under axis A, regarding the actions for energy saving in the production process:
WWTPs
1. In April 2022, the new 5-year operation and maintenance contract of the Psyttalia WWTP started, which
provides, for each contract year, a specific percentage of guaranteed energy optimization (through the
execution of works related to the supply and installation of new equipment and operational adjustments on
existing and planned new facilities and equipment units).
Overall, an overall reduction of 34.78% (at a minimum) in the energy consumption of the Psyttalia WWTP is
expected in the 5th contract year.
2. Projects aiming at further energy utilisation of the biogas produced at the Metamorphosis WWTP, with the
installation of a combined heat and power (CHP) unit, have been included in the investment programme.
WTPs
3. The Polydendri WTP has a nominal refining capacity of 200,000 m³/d. The two pumping stations for untreated
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 water treatment plant for the uninterrupted water
supply of the capital city, the design of the project "ENERGY UPGRADE AND CONSTRUCTION OF NEW PUMPING
FACILITIES OF THE POLYDENDRI WTP" has been completed and its tender is expected in the 3rd quarter of 2024.
The project among others includes:
the replacement of pumps with new modern high efficiency pumps and low loss motors,
the construction of a new refined water pumping station building
the replacement of Medium Voltage Substations with very low loss substations in accordance with the
latest EU directive.
the installation of a modern distribution network and motor control systems.
Graphics
131
The project is scheduled for completion in 2027.
4. The Acharnai WTP has a total nominal refining capacity of 850,000 m³/d. The Old Unit of the WTP has a nominal
refining capacity of 600,000 m³/d and the New Unit has a nominal refining capacity of 250,000 m³/d. The treated
water backwashing pump station and the sixteen double-clutch refining filters were built in the 1970s and have
been operating continuously since then with the same pump units and the same air and water distribution
network, with very low efficiency, resulting in significant consumption. In order to reduce energy consumption
and ensure the safety of the WTP’s operation and the uninterrupted supply of water to the capital city, the
energy upgrade of the refining and backwashing system was completed with the construction of a new pumping
station and a new water and air network. Specifically, the project included:
the replacement of the pumps with new modern pumps of high efficiency and low energy consumption
the replacement of the existing backwashing and air network with new modern, low energy consumption
pneumatic valves
an automatic control system for the operation of the backwashing pump station with the installation of a
new SCADA
installation of an (alternative) gravity backwashing network.
5. In 2023, major actions were put into action at the WTPs, which are expected to be completed in 2024, through
which, in addition to safety and functionality, further reduction of energy consumption will be achieved. In
particular, the following will be implemented:
The replacement of sixty-six (66) low energy consumption electric servo motors to replace the pneumatic
valves of the refining filters of the New Unit of the Acharnai WWTP, which have been operating
continuously since 1992.
The supply of thirty (30) new low energy consumption dosing pumps for sodium hypochlorite,
polyelectrolyte and liquid aluminium sulphate.
The supply of new modern vertical pump units of high efficiency and low energy consumption for the
Recovery Unit of the Aspropyrgos WTP.
The replacement of one hundred (100) new low energy consumption electric servo drives for the full
automation of all the processes in the final stage of the water treatment of the WTPs.
The replacement of twelve (12) modern air compressors with low energy consumption.
The replacement of nine (9) modern low energy consumption blowers.
The continuous energy saving actions in the WTPs yielded an electricity reduction by 476,820 kWh (-10%) in 2022
compared to 2021 and 519,956 kWh (-11%) in 2023 compared to 2022. The above actions are expected to further
reduce energy consumption by approximately 200,000 kWh compared to 2023.

Low consumption lighting lamps
11. The installation of low consumption street lighting lamps in eight outdoor areas of EYDAP was completed
(Acharnai WTP, Galatsi WTP, Polydendri WTP, Aspropyrgos WTP, Metamorphosis WWTP, Psyttaleia WWTP,
Thriasio WWTP, around Marathon Lake).
12. Energy upgrade of existing buildings by replacing conventional lighting with energy-saving lamps.
Energy Upgrade of KEREFYT
13. The Research Centre of EYDAP (KEREFYT) is on its way to annihilate its electricity purchase and pollutants.
Thermo-photovoltaic panels (ATPV System) with a self-generation capacity of 72.8 MWh have already been
installed for cogeneration of electricity and thermal energy while LED technology lamps were installed and
obsolete fan-coils were rehabilitated. The energy upgrade of KEREFYT started in December 2022 and is expected
to be completed and delivered before June 2023.
Hydroelectric and PV plants along the Mornos waterway
14. Preparation of reconnaissance studies for the identification and exploitation of any escaped hydrodynamics
at the locations of the Hydroelectric projects located along the Mornos waterway, as well as the possibility
of installing new PV plants at the EYDAP facilities.
Total estimated increase the generation from RES from the rationalization/upgrade of all existing SHPSs (Kirfi,
Elikonas, Kithaironas and Mandra) : 17 GWh / year, and estimated energy production from the development of
new PVs on EYDAP owned sites : 41.5 GWh / year.
Under the axis C, regarding the actions for electricity supply contracts
15. The tender for the electricity supply to EYDAP S.A. facilities has been completed and is in the process of signing
the contract, with a requirement that 50% of it shall be with guarantees of origin from RES.
Optimization of transport management
16. It concerns a project of three interconnected phases, which will form the overall framework of transport needs,
including its leased vehicles and machinery:
Redesign of the Target Operating Model- TOM of the Transport Services
Development of Fleet Management specifications
Strategic Allocation Design of Transport Services Requirements
The project started in 2021. In 2022, the needs for the renewal of the company's owned fleet and the lease of electric
vehicles were updated, while the process of drafting technical specifications for environmentally friendly (low
emission or electric) vehicles was started.

EYDAP proceeded in the pilot application of an innovative material, the Environmental Fuel Additive, which is
derived from the fossil fuel technology sector, to reduce the carbon footprint from internal combustion engines.
The use of the Environmental Fuel Additive reduces:
Drastically the Black Carbon (PM, CO, HC), i.e. the second largest anthropogenic contributor to Climate
Change which bears 2/3 of the climate impact of CO2. It, also, reduces the consumption of liquid fossil fuels
and, to the same extent, the emissions of carbon dioxide (CO2) and nitrogen oxides (NOx) and
the fuel consumption, resulting in a further percentage reduction in pollutant values, including CO2
(Carbon Dioxide) and NOx (Nitrogen Oxides), without increasing the concentration (ppm) in the volume of
residual combustion products and without creating new ones.
Following the outcome of the pilot application, it was found:
60% improvement in pollutants and exhaust emissions
15% fuel reduction
reduction of operating costs
In order to manage the fleet of vehicles and machinery more efficiently, its use was extended to all gas stations
and all vehicles and machinery of EYDAP.
R&D Actions
1. European co-funded programme "Urban Innovative Action" (UIA) 05-255 CULTURAL HID.R.A.N.T.
Facing the growing urban heat island, EYDAP participates in the European co-funded programme "Urban Innovative
Action" (UIA) 05-255 CULTURAL HID.R.A.N.T. coordinated by the Municipality of Halandri for the utilization of water
from the Hadrian aqueduct and the green regeneration of public spaces that it will irrigate in Halandri. This is a pilot
project, useful for the development of a strategy towards an integrated spatial investment (ISI) along the entire
length of the Hadrian Aqueduct in the basin (24 km). EYDAP is preparing the above strategy.
2. TRINEFLEX Research Project (https://trineflex.eu/)
The TRINEFLEX research project is developing an integrated service to manage the energy consumption of large
facilities and their transition to more flexible and sustainable operation. The project is implemented at the
Metamorphosis WWTP. A digital process twin and a model to reduce energy consumption and carbon footprint will
be developed to improve the energy efficiency of the selected processes by >7%, the energy costs by >12% and the
emissions by >20%.
1.4. CIRCULAR ECONOMY material topic
Our impacts
A. Circular Economy in Water Resources Management & Sludge Management
In the Water Treatment Plants, integrated water management includes:
the adoption of good practices , with the aim of reducing the consumption of water used for its treatment.
The water used in all stages of water treatment (emptying of the flocculation-settling tanks, cleaning-sweeping
of these tanks, backwashing of filters) is not discarded, but is recycled and reintroduced into the production
process.
the construction of projects for the treatment of sludge in the WTP, with which the reuse of the water
resulting from the centrifugation of the sludge resulting from the water purification process is achieved. This
water is added to the quantities of water used for washing the filters of the refineries, all of which returns to
the entrance of the MEN, to be processed again.
EYDAP SA in all Water Treatment Plants and in the context of the sustainable management of water resources,
invests in their upgrading, Proceeds in the construction of the necessary additional projects and technical processes

in order to optimize the treatment and manage the sludge produced as waste, according to the water treatment
process.
Sludge Treatment in WTP
The sludge produced from the water treatment is further processed, the solid waste is separated from the water,
and then the water enters the entrance of each WTP, for further treatment. The produced solid, now sludge, is
collected and transported to licensed areas.
The quantities of solid sludge produced, as they result from its treatment:
are recorded on an annual basis

in the online platform for the collection and processing of waste production
and management data (HMA), in accordance with the relevant legislation and,
are collected by licensed companies for further utilization, as a soil conditioner, for various crops in cases of
tree planting , for the cement industry and coke ceramics.

B. Circular Economy in Wastewater Management
New Projects of East Attica
The integrated management of East Attica's wastewater is a strategic goal of EYDAP. The design includes the reuse
of treated effluents, using cutting edge technology and in full compliance with the current institutional framework
for reuse.
Detailed reference to the subject in the "EYDAP Wastewater Network - Wastewater Collection & Treatment - Projects
in East Attica " section of the same Report.
Wastewater Treatment Plants (WWTPs)
During the treatment of wastewater, solid waste is produced, which basically consists of the by-products of pre-
treatment of wastewater and sludge. This is non-hazardous waste, the responsible disposal and management of
which is a priority for EYDAP's stakeholders, such as the local communities, close to the WWTP, taking into account
their large annual quantities.
At the WWTP
The solid waste resulting from the pre-treatment stage of the wastewater (screening water, sand and
heavy solids), as well as from the treatment of the primary treated sludge (fine screening sludge ) is
landfilled.
The dehydrated sludge , produced by all three Wastewater Treatment Plants, is dried at the Psyttalia WWTP.
All the quantity of the dried product produced is thermally utilized in cement factories, as an alternative fuel,
based on a licensed process, applying a technologically modern, environmentally acceptable and sustainable
management solution. The process of characterizing the dried sludge produced at WWTPs as an alternative fuel
is in progress.
The biogas produced at the phase of sludge refinement at Psyttalia and Metamorfosi WWTPS is utilized for
energy production. Specifically:
in Psittaleia WWTP all the biogas produced is self-consumed and utilized within the facilities for the
production of electricity and thermal energy.
in Metamorfosi WWTP 70 % of the biogas produced is self-consumed and utilized within the facilities for
the production of thermal energy.
Further energy utilization of the biogas produced in Metamorphosis WWTP is planned, with the installation of a
cogeneration of electrical and thermal energy plant (CHP).
units of electricity and thermal energy are operating in the Psyttalia WWTP, burning biogas and natural gas.
The electricity produced is self-consumed at Psyttalia WWTP, while any excess is exported to the to the HEDNO
(Hellenic Electricity Distribution Network Operator) power grid.

Sale of EYDAP'S SURPLUS OR OBSOLETE MATERIAL
Since December 2020, a new Regulation applies, with the aim of improving inventory management and it is applied
in cases of sales of all kinds of excess or obsolete material, movable assets and consumables of the Company. Our
basic rationale is that the above is not a useless burden but a valuable resource, which, if properly utilized, can
provide multiple benefits with a positive economic and environmental impact.In 2023, 2 new centralized Public
Tenders were held, one for the sale of aged timber following the tender of 2022 which was deemed Barren (budget
€15,725.42) and one for the sale of brass (budget €718,708.20) and their awards are awaited.
It is clarified that the contractors of the sales tenders are obliged to manage the materials based on the legislation
on alternative waste management and are certified or cooperate with certified bodies. The method of calculating
the value of the contracts is based on the values of the units of measurement, depending on the sold material.

2. SOCIETY
2.1. HEALTH & SAFETY OF EMPLOYEES & CONSUMERS material topic
2.1.1. ACCESS TO CLEAN WATER, SUPPLY & COVERAGE OF WATER SUPPLY NETWORK
The Greek State, with the new Contract concluded between the Greek State, the Asset Company EYDAP and EYDAP
SA, undertakes the obligation, throughout the duration of the Contract, to supply EYDAP SA with untreated water
of sufficient quantity to cover the needs of its consumers and quality in accordance with the requirements of the
legislation. The Greek State is also obliged to upgrade the External Aqueduct System to ensure uninterrupted supply
of untreated water to the inlet of the Water Treatment Plants (WTP).
EYDAP SA, for its part, has the exclusive responsibility - a non-transferable right - for the treatment of water, its
distribution, as well as the operation and maintenance of the proprietary water supply network, in order to cover
the water supply needs of all consumers, indiscriminately, with water of quality in accordance with the requirements
of the legislation on drinking water.
COMMITMENT
The Company manages water as a precious natural resource and as a valuable and vital commodity for the residents
of Attica (mainly).
For 2023, EYDAP SA provided:
384,147,775 m
3
of drinking water throughout its area of competence, as well as to some islands of the South
Aegean Region (Cyclades) and the Argosaronic (Municipality of Agistri through water-bearing ships), but also to
Aegina through the new submarine pipeline connection that starts from Salamina and ends in Aegina, as well
as to cruise ships and boats in the ports of Attica, etc::
minimum daily consumption 845,293 m3 (April 2023)
maximum daily consumption 1,285,164 m3 (July 2023)
average daily consumption year 2023 1,052,460 m3
2,381,795 m3 of drinking water in municipalities and municipal units located in areas outside EYDAP SA's
competence, which are supplied by EYDAP SA, after refining through 10 small rapid refining units of untreated
water taken from corresponding points of the Mornos-Evinos aqueduct.
In total in 2023, EYDAP SA distributed 386,529,570 m3 of drinking water.
RISKS
Any blockage in the supply of water resources and in the ability to transport and distribute them (External
Aqueducts - Drinking Water Supply Network, etc.) would have a significant impact on consumers (water shortage),
Graphics
141
but also on the Company itself (damage to its image, reduction of revenues, etc.), scaled proportionally according
to the size of the problem that may arise.
WATER TRANSPORT - EXTERNAL AQUEDUCT SYSTEM
Water is transported from the water abstraction sources to the water treatment plants through aqueducts and
interconnecting aqueducts, with a total length of 495 km.
The external aqueduct network is defined as all the pipelines and other works (such as pumping stations, etc.) from
the outlet of the reservoirs to the water treatment plants (WTPs).
The External Aqueduct System is illustrated in the map below.
Despite the great distance of the main water sources (Mornos, Evinos) from Attica, most of the water is transported
through the aqueducts by the force of gravity, without the economic and environmental burden of energy-intensive
pumping, which is only used in cases of emergency, thus actively contributing to the reduction of the environmental
footprint.
PROTECTION OF THE TRANSPORT OF UNTREATED WATER - EWS PROJECTS
In order to ensure the security of the capital's water supply, the implementation of four important critical projects
in the External Aqueduct System System (EWS) has been planned and launched, on the one hand to support and
secure the existing critical infrastructure of the EWS and thus ensure its fuller operation, and on the other hand to
provide an alternative water supply for the entire basin from Lake Yliki. The projects involve:
1. The restoration of the Unitic Aqueduct F1800 Mornos - Marathon, section Klidi - Dafnoula
Section: Klidi - Dafnoula" was approved by the Decision of the Board of Directors of EYDAP SA No.

downstream of Kithairon.
The design and preparation of the tender documents for the project have been completed and the approval
and final acceptance of the project is expected within the second quarter of 2024. For the construction of the
project, reforestation lifting and intervention approval from the relevant Forestry Department is required for a
section of the new pipeline under construction.
In August 2022, the Ministry of Infrastructure and Transportation awarded the implementation of the projects (1, 2
& 4) to EYDAP SA, which will arise after the completion of the respective studies..
5. At the same time, the Ministry of Infrastructure and Transportation assigned to EYDAP SA the
implementation of the project for the protection of the Mornos aqueduct from rock falls in the Kithairona
canal. The project study was prepared by the EYDAP Asset Company and submitted to EYDAP SA. The project
is expected to be put out to tender within the 3rd quarter of 2024.
6. By the 02.02. 2022 signed Contract for Operation and Maintenance of the External Water Supply System of the
Capital Region, between the Greek State, the Asset Company EYDAP LEPL and EYDAP SA, EYDAP SA undertook
to prepare and submit for approval to the Ministry of Infrastructure and Transport, a proposal for the design of
the installation of an integrated system of cutting-edge technologies for the safety and monitoring of the
operation of the EWS (SCADA, Geographical Information System, Hydraulic Model, security cameras, fiber
optics, etc.).
EYDAP SA has completed the design of the above project, which consists of:
i. Proprietary Telecommunication Network based on optical fibers
ii. Monitoring and Control System of the EWS
iii. Hydraulic Model and Automatic Operation
iv. Integrated Information Technology System for the supervision and control of the EWS
The Design Proposal for the Installation of an Integrated Cutting Edge Technology System for the Safety and
Monitoring of the External Aqueduct System was presented by EYDAP SA and submitted for approval to the
Water Supply, Sewerage & Wastewater Treatment Projects Directorate (D18) of the Ministry of Environment
and Energy, in accordance with the provisions of Article 5.2 of the Operation & Maintenance Contract of the
EWS of EYDAP SA with the Greek State.
MANAGEMENT OF THE WATER SUPPLY SYSTEM
The ways and methodologies of managing the water supply system are prioritized into:
the operation of the existing water supply system,
the regulation of the flow downstream of the reservoirs,
the distribution of water abstraction by main, secondary or reserve source,
the transfer of water through the external aqueduct network,
additional works to reinforce and secure the water supply system, where necessary.
The objective of the Management Plan is the study of rational, efficient and sustainable ways and methods of
management of the External Aqueduct System, aiming at the quantitatively reliable, qualitatively and
environmentally safe and economically feasible coverage of the demand for water supply in the area under
EYDAP's competence, through the appropriate use of the water resources available for the coverage of that
demand.
The management of the water resources system consists in determining the quantities that can be withdrawn
from reservoirs and aquifers and the way they can be channeled (shared) to the network of external aqueducts, in
order to ensure the long-term adequacy of the water supply resources of the water supply area under EYDAP's

Graphics
143
competence at the lowest possible cost. It also consists of additional works to reinforce the water supply system, if
necessary.
The Decision Support System, which is used operationally on a daily basis by EYDAP for the supervision and
management of the water supply system, includes the following components (subsystems):
a) Geographical Information System for the visualisation and monitoring of the water supply system,
b) A system for measuring the water resources of Athens' water supply,
c) System for estimating and forecasting the water resources of Athens' water supply,
d) A system to support the management of the water resources of Athens' water supply.
Further technical, quantitative and qualitative data can be obtained from the corporate website eydap.gr in the
section "The Company/Water Supply".
LEAKAGE REDUCTION
EYDAP manages the demand for water by developing LEAK REDUCTION programs (pressure management - water
zones, immediate repair of damages - broken pipes of the water supply network, rehabilitation and replacement of
water supply networks), aiming not only to serve customers, but also to protect against waste of the natural
resource.
Aiming at the economically optimal identification of water loss management strategies, EYDAP SA collaborates
with a specialized scientific team of the School of Civil Engineering of the NTUA through a contract from 2021, in
order to develop computational tools, tailored to the needs of the network, which will support the Company at the
operational level.
The operational tools to be developed will focus on the optimal prioritization of the replacement of the network's
pipelines, as well as on the optimal management of pressures, in order to reduce the actual water losses of the water
supply network of EYDAP SA.
In addition, these innovative decision support applications will be integrated with the existing software and systems
of the Company, as well as with the simulation model of the primary and secondary network.
In order to implement the operational tools in the entire water supply network, EYDAP SA has already started to
update the existing simulation model of the main supply pipelines, as well as to create the mathematical simulations
of the networks of the piezometric zones.
The modelling of the water supply network is particularly important, as it allows the simulation of different operating
scenarios. Through the simulations and the direct monitoring and evaluation of the results, EYDAP SA can take
decisions on network optimisation, operation, extension or reinforcement.
Moreover, with the development of the mathematical simulations of the water supply network, the Company is
laying the foundations for the future infrastructure of the Digital Twin of the water supply network and its
communication with other operational tools, in order to monitor the operation of the network in real time, as well
as to make optimal decisions for the management of the network.
WATER SUPPLY TO NEW AREAS AND REINFORCEMENT OF EXISTING AREAS
Today, EYDAP SA provides excellent quality drinking water, in the necessary quantity and pressure, regardless of
whether the Company is responsible for the management of the distribution networks primarily or whether this
is carried out by the local municipalities.
For the few areas that are not supplied with water by EYDAP but by boreholes, mainly in Western Attica, EYDAP SA
has launched a series of interventions and actions, in cooperation with the local authorities, so that in a short period
of time they will be included in the total number of areas that will receive water from EYDAP.
In this direction, the implementation of the project "Water supply to the Kinetta Settlement of Megara -
Phase A" was launched, which includes the construction of a new steel supply pipeline F500, approximately
15km long, as well as a water reservoir, through which the area of Kinetta will be supplied with water,
which until now is not supplied with water by EYDAP.

In October 2023, the Board of Directors approved the launch of a new public e-tender for the completion
of the implementation of the project "Completion of the remaining works for the water supply of the
settlement of Kinetta Megara, Phase A: 1) External water supply pipeline, 2) Central reservoir".
In addition, the implementation of the project " Feeder Pipeline of Perama Reservoirs from Schistos
Avenue", for the construction of a new steel feeder pipeline, cross-section F300-F600 and a length of
approximately 4km, which will supply the existing reservoirs of the Municipality of Perama, without the
help of the boosters that are currently used for the water supply of the area, thus reducing to a minimum
the current consumption of electricity. The project is currently underway and is expected to be completed
within 2024.
In October 2023, the Board of Directors approved the launch of a new public e-tender for the
implementation of the project "Reinforcement of the central water supply network of EYDAP SA in West
Attica - Construction of a new supply pipeline of cross-section F1000", in order to meet the increasing
demand requirements of the wider area in West Attica and the islands of Salamis and Aegina, with a total
length of 15,440m.
In July 2023, the Board approved. the launch of a new public e-tender for the implementation of the project
"Replacement of the water supply pipeline of cross-section F1300: Section Kiourka - Pumping Station of
Agios Stefanos", for the replacement of the existing discharge pipeline of prestressed concrete, diameter
F1300, with a new steel pipeline of the same diameter, in an area of 3120m between the pumping stations
of Polydendri and Agios Stefanos. The tender procedure is currently underway.
In the framework of the approved investment program of the General Directorate of Water Supply of EYDAP
SA, the project " Works to strengthen the central water supply network of EYDAP SA, in the South Sector
of Athens" was launched, which was deemed necessary to meet the increased demand requirements, with
the inclusion of the new metropolitan pole Elliniko-Ag. Kosmas, in the supply network of EYDAP SA. The
final design and tender documents for the project are expected to be completed within the 2nd quarter of
2024.
2.1.2 RELIABLE WATER SUPPLY NETWORK
For EYDAP, ensuring throughout the water supply system sufficient quantities of high quality drinking water at
acceptable pressure conditions, while protecting the natural resource, is a key priority.
The design, construction, operation, maintenance and continuous development of the water supply network is a
complex multi-factorial process, requiring a high level of expertise.
A region's water supply system, which ensures the supply of drinking water to the region, comprises a system of
reservoirs, supply (main) pipelines, distribution pipelines and water supplies.
The term 'water supply network' refers to all the pipelines carrying treated water from the local water treatment
plants to the water meters of the consumers. It is the main part of the entire water supply company's facilities, most
of which is underground. The water supply network provides pressurised water suitable for human consumption, in
accordance with the Greek legislation in force.
The size of the area supplied with water, the morphology of the land, the density of the population and the estimated
change as well as its geographical distribution, the height of the buildings, the expected consumption by calculating
the average daily consumption - low and high - are some of the factors that determine the quantity of drinking water
supplied, the pressure of the supply and thus the rational design of the network.
The water supply network consists of approximately 14,500 km of supply pipelines and distribution network.
The main supply network (primary network) is about 1,300 km long and consists of pipes with diameters ranging
from F300 mm to F2000 mm.
The distribution network is approximately 13,200 km long and consists of the secondary and tertiary networks,
which have a total length of approximately 9,000 and 4,200 km respectively.
The distribution network consists of pipelines with a diameter of less than F300 mm, which transport drinking water
to consumers.

The water supply network has:
Reservoirs: 53
Pumping stations: 77 (total installed capacity of 33,200 HP)
Pressure reducing valves: 622 ("F80-F600")
Isolation valves: approximately 90,000
Remote monitoring points (Scada): 108
Telemetry stations (GPRS): 1510 (25 new stations added in 2023)
Flowmeters: 195 (15 new ones added in 2023)
Water quality monitoring points: 1000 (700 for chlorine measurements and 300 combined for chlorine
measurements and other parameters as required by legislation).
Our impacts
MONITORING AND IMPROVEMENT OF WATER SYSTEM OPERATION (demand monitoring, pressure monitoring,
pressure zone modifications, etc.).
Attica is characterised by its rugged terrain. EYDAP SA supplies water to areas with ground elevations from 0 to 600
metres above sea level. In order to better control the pressure of the pipelines, pressure zones have been created,
i.e. ground areas with a specific pressure every 30 to 40 metres of altitude difference. The range of pressures within
the hydraulic zones varies from 2 to 12 atm with the vast majority ranging from 4 to 6 atm. The water supply network
is monitored on a 24-hour basis by a remote control - remote management system (SCADA).
NETWORK MAINTENANCE - PREVENTIVE AND EMERGENCY (maintenance of pumping stations, fire hydrants,
cleaning of reservoirs, repairs of leaking pipes - supplies etc.).
Preventive maintenance of the water supply network infrastructure (pumping stations, tanks, special manholes and
large valves, fire hydrants, etc.) is carried out in accordance with programs prepared by the competent services of
the water supply network.
In addition to the above, the resulting daily failures of the water supply network that cause leaks or breaks in the
network, are collected in the telephone center for failures - complaints of EYDAP (1022) and the portal of Water
Supply and are routed for repair to the competent technicians of the Water Supply Sectors. Their repair, where they
cause water supply deprivation areas is implemented immediately, so as to minimize the nuisance caused to
consumers - customers and to restore the normal water supply of areas where the network is damaged.
In 2023, the total number of leaks - breakages, both of pipelines and valves in all the networks operated by EYDAP,
whether or not they caused water supply deprivation, amounted to 6,237. These leaks were repaired in their entirety
immediately by the services of the General Directorate of Water Supply.
Non-revenue water (NRW) for 2023 was calculated at 23.70 % (reduced compared to 2022 NRW-23.96 and 2021 -
NRW: 24.75 %). Of the percentage of the non-revenue water for 2023, the percentage of actual losses amounts to
approximately 15%.
Actual water loss is the difference between total water losses and apparent losses (unauthorised consumption and
meter and measurement errors).
EXTENSION, REPLACEMENT AND REHABILITATION OF EXISTING PIPELINES AND WATER SUPPLIES OF PROPERTIES
The existing network of EYDAP SA consists of pipelines of different cross-sections and different materials, which have
been installed over the years to serve the increased water supply needs of the residents of Attica.
Many of these pipelines have been in operation for many years, and due to the original conditions of their installation
and due to the development of the city and the successive reconfigurations of roads and other public spaces,
combined with other nuisances (traffic, other external factors), they have been subjected to significant stresses
leading to frequent breakages. Similarly, the water courses of the properties supplied by these pipelines are of the
same age and are subject to similar stresses as the pipelines. The operating conditions of these pipelines are assessed
by EYDAP and then programs are defined and implemented to replace them with new pipelines and water mains

made of the most modern materials.
In 2023, EYDAP replaced, installed new and relocated a total of 79,268.36 m of pipelines. In detail, the following
were carried out:
Replacement of existing pipelines: 71.783,20 m of pipelines of cross section F63, F90, F110, F160, F200, F250,
F300, F315
Laying of new pipelines: 7.485,16 m
Of the total new pipeline installations (7,485.16 m of pipelines), 5,499.80 m related to paid extensions of
pipelines of the water supply network by customers-consumers, in order to achieve the installation of
waterfalls in front of their properties and 1,985.36 m related to pipeline extensions resulting from the general
planning of new pipeline installations of the General Directorate of Water Supply.
Displacements of existing pipelines: 1.311,2 m
In the context of works carried out by third parties, EYDAP is invited to intervene in its network to facilitate the
execution of new works taking place on the city's streets. In this context, in 2023, 1,311.20 m of pipelines were
laid either to replace existing ones (822.20 m) or to meet new water supply needs arising from third party
interventions in the city (489 m) (indicatively, Metro line 4, ERGOSE undergrounding projects, etc.).
Water mains rehabilitation: 12,125 water mains of properties were replaced/rehabilitated
In 2023, a project was launched to repair 46 cathodic protection stations on water supply mains. "Provision of
services for the rehabilitation of 46 cathodic protection stations of EYDAP SA, the supply, installation and
commissioning of an integrated telemetry system as well as technical support, maintenance of these for a
period of 5 years". The tender of the project is expected to be completed in the 3rd quarter of 2024.
15,299 water meters were replaced in 2023
By the Decision of the Board of Directors of EYDAP SA No. 21720/8-11-2023, a project entitled "Projects for the
implementation of technical actions of the Water Supply Network Directorate" was approved, through which,
among other things, the replacement of approximately 180,000 mechanical water meters will be completed in
approximately 3 years, within the framework of the implementation of corresponding technical actions issued by
relevant reports of the metering crews of EYDAP SA. The project is expected to be put out to tender in the 2nd
quarter of 2024.
The General Directorate of Water Supply, in the context of its modernization effort and recognizing the need to
develop a new, modern software for the management of the technical actions implemented by its Services, piloted
the integration of the "ATLAS Technical Services Software" platform in the daily execution of technical actions for
the replacement of water meters, with provision for the implementation of all types of Technical Actions, through
appropriate configuration.
NEW WATER SUPPLIES: EYDAP continues to install new common water supplies and special supplies to properties,
upon request and as long as they are approved in accordance with the provisions of the Water Supply Networks
Operation Regulation.
The water supplies connected to the water mains are divided into:
Water supply, fire-fighting, common areas of properties, irrigation of public or municipal areas, temporary for
construction or other use.
In 2023, EYDAP installed approximately 8,615 residential, special and firefighting supplies (about 427 more than in
2022), a number that confirms the continuation of the intense construction activity in the city.
FIRE HYDRANTS: in 2023, having as a priority the prevention, preparedness and protection of life, health and the
environment from fires, EYDAP, in cooperation with the Fire Service, carried out the inspection of the good
functioning of all the installed Fire Hydrants. The checks carried out revealed the need to intervene in a total of 212
fire hydrants, as follows:
Repair: 170
Replacement: 31 non-operational
Installation of new ones: 11

147
TANKS: in order to ensure the good quality of the water supplied to the consumer, EYDAP carries out periodic
cleaning of the water storage tanks every three years. Based on this schedule, 16 water storage tanks in the water
supply network were cleaned in 2023. In 2024, the implementation of a renovation and modernisation project in a
significant number of tanks in the water supply network is planned.
TAKEOVERS OF NEW NETWORKS
EYDAP takes over water supply networks within its area of competence, which are managed by the local municipality
concerned. The acceptance of these networks, currently mainly concentrated in East and West Attica, is a strategic
objective for EYDAP.
The takeover of the Municipal Water Supply Networks by EYDAP is not done unilaterally. The key prerequisite for
this is the positive decision of the Municipal Council of the Municipality.
In 2021, the contract for the transfer and delivery to EYDAP SA of the municipal water supply and sewage
network and the Wastewater Treatment Plant of the city of Megara, the municipal sewage network of the city
of Nea Peramos was signed, the municipal water supply networks of the areas of Kinetta, Vlychada (Agios
Panteleimonas), Nea Zoi, Kandylio, Koumindrio, Lakka, Agia Triada, Iremo Kima and Pachi of the Municipality
of Megara and the acknowledgement of debts of the Municipality of Megara to EYDAP SA. On 1/9/2023 the
relevant delivery and acceptance protocol was signed and now EYDAP SA has been installed in the Municipality
and has taken over the management of the network. From December 2023, a new Customer Service Center
will be operating in the area, to better serve the citizens.
As part of the interventions launched by EYDAP SA for the improvement, replacement and modernization of
received municipal networks, a project of extensions, improvements and replacements of pipelines, water
mains and other installations of the water supply network of the island of Salamina is underway, which EYDAP
SA took over in its entirety in 2021. According to the design of the project, the replacement of approximately
75 km of secondary and tertiary network, as well as the rehabilitation of approximately 5500 water supplies of
properties with their respective water meters is anticipated.
The operation of the water supply network is determined by the Water Supply Network Operation Regulation
(WSNOR) (Government Gazette 552/B’/26-03-2009).
OPTIMISATION OF THE WATER SUPPLY NETWORK
The Company has included the following in its strategic actions for the optimal management of its network:
The application of modern technologies of advanced pressure management in the water supply network, which
results in avoiding unnecessary stress on the network's pipelines from excessive pressures and, consequently,
avoiding network breakages, thus achieving an increase in service life over a long length of the network with
significant economic benefits.
Reliable and organised data collection from faults, operation, etc. in order to achieve further processing and
statistical analysis of the collected data through structured and cooperative applications.
The identification of the frequency of occurrence of faults, the speed and quality of repairs, the determination
of their geographical distribution, the cause of their occurrence, etc. in order to draw up a comprehensive and
systematic maintenance schedule for the water supply network.
In order to implement the above strategies, EYDAP SA has included in its five-year investment program:
The implementation of a targeted program of massive network replacement in identified hydraulic zones of
the water supply network. For this program, the tendering procedures have been completed and projects are
expected to start in all sectors of EYDAP SA, which include 480 km of secondary and tertiary network pipelines
and the corresponding rehabilitation - replacement of more than 111,000 water meters of properties.
The implementation of a targeted program, with substantiated priority of water supply network replacement,
which includes works for extensions, improvements and replacements of water supply network pipelines in
EYDAP SA's Sectors (Athens, Piraeus, Heraklion and West Attica), which include replacements of approximately
380km of secondary and tertiary network pipelines.
Through the aforementioned interventions, EYDAP SA has initiated the annual replacement of meters of the water
supply network, which corresponds to approximately 1.5% of the total length of the network, following and
complying with international best practices.

Graphics
148
With the above, in combination with the other actions and interventions that have already been launched (massive
replacements of water meters, interventions in supply pipelines, maintenance and renovation of existing
infrastructure such as pumping stations, water supply wells and valves, launching operational interventions in the
network through modern software and modernization of existing operating structures), is estimated to achieve more
efficient operation of the water supply network, consistent reliable and uninterrupted water supply, improved level
of service to consumers, further reduction of Non-Revenue Water and ultimately improved overall corporate image
regarding the performance of its services.
“SMART GRID”
Aiming at the Sustainability of the resource alongside modernization and optimization of network and asset
management, the Company is in the process of developing a "Smart Grid".
The "Smart Grid":
Includes information and communication technologies in the distribution infrastructure and throughout its
operation. The advantage of "smart meters" is that they calculate the relevant measurements at a more
advanced level, communicate with the latest technologies and send information for monitoring, prevention,
resource conservation and better billing purposes
contribute to the implementation of water saving works (reduction of losses, optimization and automation of
water resource management)
can meet future demand growth, enhance the efficiency of network operation and integrate smart devices to
improve service and customer interaction
regulates and controls the distribution of the resource and aims at smart connection of consumers and
production
contribute to ensuring a more economic and secure network with reduced losses and meeting demand in real
time.
Through these, EYDAP can now:
collect detailed data on the status of each specific supply with a remotely scheduled rate of data collection
and transmission to a central infrastructure (Operations Center)
provide consumption and supply information in detail and in graphical form to its special customers online.
EYDAP SA up until 31/12/23:
Has replaced 1,118 (28 new ones within 2023) special supply old mechanical water meters of 2-inch to 6-inch
diameter with the installation of corresponding smart meters with the same number of dataloggers.
has already implemented (years 2017-2018) two pilot applications with the installation of 83,500 electronic
household water meters in the Municipalities of Halandri & P. Faliro, at the Varvakeios Market and the streets
around it.
"Multiutility" Pilot Project
Since December 2023, EYDAP SA in cooperation with DEDIE, has launched the "Multiutility" pilot project in order to
use the infrastructure of DEDIE's new smart electronic meters for the implementation of a wireless communication
network to receive data from meters of other operators, including EYDAP SA. This pilot project is being developed
in an area of the Municipality of Palaio Faliro and in particular in a part of a pressure management area (DMA). The
duration of the pilot project is 7 months and during this period there will be:
installation of electrometers (electronic smart electricity meters) in selected buildings
coupling these with EYDAP SA's electronic water meters in this area
wireless transmission of data to a special platform already allocated to EYDAP for the purposes of the pilot
project.
In the first phase of the project, 40 electrometers will be installed and about 200 water meters will be paired.
In the second phase 560 electrometers will be installed and all the water meters in the zone, about 2500, will be
connected. At the end of this phase, a dense communication network will have been established to collect
consumption data from all the water meters with time breakdown, so that, together with the monitoring of the
consumption of the flow meter at the inlet of this zone, continuous monitoring of the water balance will be possible.
In 2023, the procedures for the tender for the replacement of the remaining mechanical water meters of special
supplies with the installation of new electronic water meters were launched and are expected to be completed in
2024, with the aim of fully covering the special supplies (water meter cross-section ≥2") with electronic water meters

Graphics
149
and the replacement of the remaining water meters of 1.5" cross-section with new mechanical water meters.
EYDAP has included in its investment program the installation of new household smart meters to replace existing
older technology ones in order to transition to the smart water network and modern technologies.
For the successful implementation of the project, EYDAP has launched a tender procedure for the provision of
services:
The preparation of the detailed business plan with a detailed assessment of the capital, operational and
financial requirements of the investment
The formulation of EYDAP's procurement strategy for the supply and installation of smart meters and their
information and telecommunications infrastructure
The design of the strategy and key principles of the project implementation and operation model
EYDAP's objective in the Water Sector is the steady and targeted transition to new technologies by monitoring
and exploiting all the current trends of the technologically advanced international water market.
In this direction, EYDAP executives follow the actions of international water organizations and international water-
related exhibitions, visit large factories producing materials and equipment and are in constant consultation with
other advanced water companies and international practices that have incorporated or have started to incorporate
new technologies in order to transition to the smart water network.
PARTNERSHIPS - Digital Innovation Challenge
An original, open competition of technological innovations, announced in November 2020 in collaboration with
HCAP Innovation Network and MIT Enterprise Forum Greece; start-ups, teams of scientists, university research
centers, etc. were invited to offer innovative solutions. The winner of the call for "finding the defective meters" was
WINGS, with whom a contract was signed for the implementation and application of the algorithm for the detection
of defective meters, which is currently in progress.
2.1.3 QUALITY OF DRINKING WATER
EYDAP, as the largest provider of water supply services, aware of its responsibility towards millions of consumers,
ensures the excellent quality of drinking water. Through continuous investment in infrastructure, technology and
training of its human capital, EYDAP ensures drinking water quality, among the highest in Europe, always in
compliance with the applicable regulations.
INTERNATIONAL ASSESSMENTS
In the annual international assessment of water companies issued in 2023 by the European Benchmarking Co-
operation, EYDAP's water quality was rated 99.6%, higher than the average score achieved by the European
companies that participated.
Water quality is ranked 1st out of 180 countries worldwide, with a score of 100%, according to Yale University's
Environmental Performance Index (EPI).
COMMITMENT
To provide drinking water of high quality and low cost to more and more citizens and to return it to the environment
clean, through the efficient management of all available resources, with social sensitivity and with a view to
contributing to social well-being.
WTPs - WATER TREATMENT STAGES
Water Treatment Plants (WTPs) are absolutely crucial for the water we drink, making it potable of excellent quality,
with a cumulative maximum refining capacity of 1,800,000 m3 of water per day.
The 4 WTPs are located in Galatsi, Acharnes (Menidi), Polidendri (Kiourka), Mandra in Aspropyrgos.
The surface water that arrives untreated at the WTPs is subjected to 5 treatment steps (pre-chlorination,
flocculation, sedimentation, filtration and post-chlorination).
In the pre-chlorination and post-chlorination stages, water disinfection is achieved by applying chlorine gas and now
sodium hypochlorite. Already three of the four WTPs of EYDAP SA carry out water disinfection with sodium
hypochlorite, while the fourth WTP (Polydendri) is expected to fully implement sodium hypochlorite by the 2nd
quarter of 2024. With the attempted change of the disinfectant, EYDAP SA achieves a significant transition in terms

Graphics
150
of water disinfection from chlorine gas to sodium hypochlorite, after a period of more than 80 years since the
application of chlorine gas as the main disinfectant. Furthermore, by changing the disinfectant, the Company is also
relieved of the safety data and obligations that arose due to the Seveso Treaty (CMD 172058/2016 "Determination
of measures and conditions for the response to the risks of large-scale accidents in establishments or plants due to
the presence of dangerous substances, and specifically for chlorine gas WTPs").
Through disinfection, water reaches consumers free of microorganisms and parasites and becomes healthy and safe.
In Water Treatment Plants, water is made potable by the most environmentally friendly and natural resource-
friendly methods.
More information is available on the corporate website eydap.gr in the section "The Company/Water Supply/Water
Treatment Plants".
WATER QUALITY CONTROL
EYDAP has put in place an appropriate framework of controls to ensure that the water supplied to consumers is
healthy and safe.
The water quality monitoring program has been developed to exceed the legislative requirements and includes:
daily quality checks on samples of raw and drinking water, 7 days a week,
close monitoring of the water quality of the four reservoirs, Mornos, Evinos, Marathon and Yliki, with on-site
visits, sampling and analyses at least eight (8) times/year,
daily sampling and analysis of drinking water samples from the water supply network, in order to monitor and
document the excellent quality and address any problem that may arise promptly.
sophisticated on-line systems, installed at key locations of the untreated water transport aqueducts to the water
supply network and the water treatment plants, which continuously record measurements of critical water
quality parameters.
The checks carried out, particularly on 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 legislation.
WATER QUALITY TESTING LABORATORIES
For water quality testing, EYDAP has ISO 17025 accredited laboratories in Galatsi and Acharne.
Samples are analyzed in the water quality control laboratories according to an appropriate program that defines the
parameters and frequency of testing:
untreated water from the reservoir-lakes, EYDAP's boreholes, the aqueduct and the entrances of the WTPs
drinking water from Water Treatment Plants, and
from the Company's water supply network.
EYDAP has additional laboratories for the control of the intermediate stages of water treatment, installed in each
of the four Water Treatment Plants.
Through the laboratory analyses, the Water Quality Control Department of EYDAP systematically monitors and
records, in accordance with the provisions of its ISO 17025 Quality Assurance System, not only the parameters-
materials provided for by the current legislation but also international trends in regulatory issues, which may
constitute future legislative requirements or stakeholder requirements. As a result of this action, the list of
substances monitored is continuously enriched.
For this purpose, the most modern analytical methods are applied in EYDAP's laboratories in order to achieve high
sensitivity and accuracy of measurements. Among the analytical techniques applied are UHPLC-HRMS q-TOF liquid
chromatography, gas chromatography with MS/MS "triple quadrupole", ECD, FID and olfactometry detectors, ICP-
MS and ICP-OES plasma spectroscopy, automatic photometric analysis, ion chromatography, HPLC liquid
chromatography with fluorescence and UV detectors, toxicity testing with Daphnia organisms, and many others.
As part of the continuous improvement of quality control mechanisms, our laboratories are constantly upgraded
with state-of-the-art analytical equipment, as well as equipment designed to automate and optimize laboratory
work.

Graphics
151
In this direction, within 2023, procurement procedures have been initiated and are underway for laboratory
equipment for water quality testing, including a new GC-MS/MS gas chromatography - sequential mass spectrometry
system, a new ion chromatography anion system, a new total organic carbon system, etc.
SYSTEMS FOR CONTINUOUS MONITORING OF QUALITATIVE PARAMETERS IN THE EXTERNAL AQUEDUCT SYSTEM
(EWS)
Sophisticated systems for on-line monitoring of critical quality parameters in raw water are installed since 2017 in
12 nodal locations in the external aqueducts, which send real-time results with telemetry and timely alerts in case
of extreme values.
As part of the continuous improvement of quality control mechanisms, the network of continuous monitoring
systems was expanded in 2023 to more key locations and with additional sensors. With this new supply, the tender
process for which was completed in 2023, it is now possible to continuously measure and record on-line turbidity,
temperature, conductivity and organic load (TOCeq) in the water, in 22 in total, including the existing, nodal
locations along the Mornos and Yliki branches, the Marathon waterworks and the entrances of the four Water
Treatment Plants.
Through the EWS stations, it is possible to be immediately informed about incidents related to the quality of the
incoming untreated water in the water treatment plants and therefore to take timely measures to deal with the
phenomena, so as not to create problems in water treatment in the water treatment plants, the impact of which
may affect the water to be consumed in the water supply network.
CRUCIAL QUALITY PARAMETERS MONITORED ON-LINE AND IN DRINKING WATER
The use of on-line measurements helps to reduce the need for physical human presence for taking samples,
reduces the cost of sampling and gives for some critical quality parameters the advantage of monitoring them in
the actual conditions of the water supply network and in real time.
Residual chlorine is perhaps the most critical parameter, as its presence in drinking water ensures that
microbiological risks are minimized. To this end, 53 new on-line instruments for continuous monitoring of residual
chlorine will be installed in 2024 in all the drinking water tanks of the EYDAP Water Supply Network in various
locations in Attica. The relevant tender procedures were completed in 2023 and the implementation of the Contract
is expected by the 3rd quarter of 2024.
EYDAP systematically monitors and investigates technological developments in this area. In 2018, two systems for
continuous monitoring of quality parameters were also installed in the drinking water network. In 2019 they were
enriched with additional sensors and capabilities, according to the requirements of EYDAP. 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 parameters in the water supply network, as well as early warning and prevention of
potential problems.
During 2023, two more "smart" systems for the on-line monitoring of a number of critical parameters were tested
at EYDAP's facilities (sub. Chlorine, trihalomethanes, turbidity, conductivity, pH, nitrate & nitrite ions, hexavalent
chromium, copper, iron, and other undesirable organic substances). The purpose of the pilot tests is to investigate
the evolving market in this area so that targeted investments can be initiated and EYDAP can remain a leader in
water quality testing.
COLLABORATIONS WITH SCIENTIFIC INSTITUTIONS
For the investigation of specialized water quality issues, EYDAP often collaborates with Greek Educational and
Research Institutions (NTUA, University of Patras, University of Thessaly, NCSR Demokritos, Hellenic Atomic Energy
Commission, etc.), which are among the pioneers in their field in Europe.
The results of the collaboration with the Laboratory of Analytical Chemistry of the University of Athens constitute
the first extensive study on the detection of emerging contaminants in reservoirs intended for drinking water. This

Graphics
152
has resulted in both important documentation of the good chemical status of the reservoirs of EYDAP and a list of
substances that need to be monitored. The cooperation is continuing with the study of samples from the inlet and
outlet of the four Water Treatment Plants (WTPs) of EYDAP to provide data for risk assessment in the treatment
part of the water supply system.
These data will be used in the risk assessment study of the water supply system from the water intake to the meter,
required by the forthcoming legislation, and contribute to the optimization of EYDAP's water quality monitoring
program.
Very important in 2023 was also the cooperation with the University of Patras (Laboratory of Hygiene and
Environmental Microbiology of the Medical School) in terms of scientific support, training and development of the
staff of the microbiology laboratory on water microbiology issues.
CERTIFICATIONS
The Chemical Laboratories of Galatsi and Acharne, as well as the Microbiological Laboratory are accredited
according to ELOT EN ISO 17025 already since 2005, by the National Accreditation System (ESYD), for the
performance of tests for the determination of chemical and microbiological parameters in untreated and drinking
water (Certificate No. 192).
In 2023, in order to maintain accreditation as well as to extend the scope of accreditation, an inspection of our
laboratory activities was carried out by three ESYD assessors.
As judged by the evaluators, the performance of the WQCS laboratories is highly satisfactory and reflects the high
level of its staff and as a result, it was granted:
• Maintenance of accreditation
Expansion of the Official Scope of Accreditation with two new methods for the determination of 33 additional
compounds
EYDAP's water laboratories are now accredited for more than 110 total 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 development and improvement of their operation is reflected in the
continuous expansion of the scope of laboratory accreditation, i.e. the continuous increase in the number of
substances identified using accredited methods.
COMPLAINT MANAGEMENT - CONSUMER INFORMATION
EYDAP gives particular priority to ensuring a high level of consumer satisfaction.
The Company has established a telephone hotline (1022) for the registration and rapid response to all quality issues
that may be reported by the consumer public.
In 2023, there was no incident of a consumer request not being satisfied or an incident of a fine or compensation
for water quality issues.
Reference to the "Customer Service with Security - Affordable Tariff" section of the same Report.
CONSUMER INFORMATION
EYDAP systematically ensures that consumers are informed about water quality in the following ways:
on an annual basis, the average values of all the parameters identified are extracted. These values are posted
on the Company's website so that they can be accessed by any interested party.
responds in writing by providing up-to-date information on water quality to any consumer request. In the
majority of these cases, the responses include reports of sample results taken from plumbing receptors within
the property of the parties concerned.
water quality data of EYDAP’s water supply network are systematically sent to the Ministry of Health. The
data for the three-year period 2020 - 2022 were sent in March 2023 to the Ministry of Health and the Ministry
of Environment. The Ministry of Health sends the data received from all water operators to the European
Commission and also posts them on its own website for public information.

NEW LEGISLATION ON THE QUALITY OF WATER INTENDED FOR HUMAN CONSUMPTION
In 2023, the publication of the no. D1 (d)/GP oik. 27829/15-5-2023 CMD (Government Gazette 3525/B/25-5-2023),
concerning the "Quality of water for human consumption in compliance with the provisions of Directive (EU)
2020/2184 of the European Parliament and of the Council of 16 December 2020 (L435/1, 23.12.2020)".
The aim of the new CMD is to protect human health from the adverse effects of contamination of water for human
consumption by ensuring that it is healthy and clean, and to improve access to water for human consumption.
The main additions/modifications to the new CMD, compared to the previous corresponding one that is being
repealed (C1(d)/GP οικ.67322/6.9.2017), are briefly listed below:
Drinking water parameters and limits are updated based on the latest scientific data and World Health
Organization guidelines.
Water safety risk assessment is introduced as the key driver for the development of quality monitoring programs.
Measures are foreseen to assess and mitigate water loss.
Measures are introduced to increase access to drinking water.
Water operators are required to provide consumers with adequate, up-to-date information on water for human
consumption,
Rules for "operational" monitoring are established to check more systematically the effectiveness of water
treatment.
Provision is made for rules on materials in contact with drinking water and treatment media.
Selected EYDAP executives, due to their expertise and experience, participated both in the consultation for the
adoption of the EU 2020/2184 Directive and in the Working Group of the Ministry of Health for the harmonization
of Greek legislation and the adoption of the CMD.
It is also noted that EYDAP, with all the actions mentioned above, has ensured the strict compliance with the new
CMD from the first day of its implementation.
COMPLIANCE WITH CONTRACTUAL OBLIGATIONS WITH THE GREEK STATE
In order to comply with the obligations of the new Contract of Law 4812/2021 between the Greek State, the EYDAP
Asset Company and EYDAP SA, the raw water quality data and the data on the quality of water for human
consumption are now systematically sent to the Ministry of Environment.
RECOGNITION
As documented by the results of about 170,000 determinations on about 10,000 drinking water samples and 2,000
untreated water samples per year, EYDAP continuously certifies that Athens' water is of excellent quality and one
of the best in Europe.
The results of the analyses certify that the quality of the drinking water of EYDAP meets the legislative
requirements of CMD D1 (d)/GP oik. 27829/15-5-2023 (Government Gazette 3525/B/25-5-2023), concerning the
"Quality of water for human consumption in compliance with the provisions of Directive (EU) 2020/2184".
COMPLIANCE WITH REGULATIONS AND STANDARDS
During the reporting period, no incidents of non-compliance with regulations and rules related to water quality
and negative impacts on CONSUMER HEALTH and SAFETY were identified.
The drinking water quality control data from the water supply network of EYDAP SA is available on the corporate
website eydap.gr in the section "The Company/Water Supply/Raw Water Quality Control".
R&D Actions in the context of ensuring the quality of drinking water.
The ToDrinq project (https://todrinq.eu/) is underway and will deliver to the Polydendri Water Treatment Plant an
integrated pilot system for the control of quality parameters that could not previously be controlled by
conventional means. In addition, it delivers an inter-functional decision-making tool, which will act as an advisory
tool to the operators and designers of the Water Treatment Plant.
In 2023, EYDAP carried out a complete upgrade of its 2 autonomous robotic vessels (USV) to monitor the quality
characteristics of water reservoirs for human consumption. Now the vessels will be able in a minimum of time to

act operationally throughout the reservoirs, identifying in time potential pollutant inflow points. The vessels were
deployed in 2023 as part of the company's research projects.
2.1.4 EYDAP WASTEWATER NETWORK WASTEWATER COLLECTON & TREATMENT PROECTS IN EAST ATTICA
Attica's Sustainable Development is closely linked to the responsible and effective management of wastewater.
EYDAP today, as the largest company in Greece operating in the water cycle, takes care of the collection and
treatment of wastewater and returns to the environment treated water free of pollutant load, applying the most
modern international practices.
We are committed to a continuous and dynamic presence in this sector, through our undeniable high level of
expertise and with the main objective of protecting natural resources, using modern methods of circular economy
and the continuous upgrading of the quality of life of citizens.
EYDAP's operation and especially the disposal and treatment of residential, institutional, factory and other
installations is based on the regulatory provisions of Greek and European legislation and corporate initiatives.
RISKS: the recognition, assessment and control of potential risks are very critical and important factors that the
Company manages with particular attention through the preparation of a specific Business Plan, being aware of
their economic, social and environmental impact. The main risks related to sanitation issues are:
environmental degradation in areas where there is no sewerage network
wastewater inflow into properties or escape into the environment (roads, streams) due to overflows or
blockages of pipes
problems in the operation of wastewater treatment plants due to discharge into the network of inappropriate
for treatment effluent
pollution of marine ecosystem in the event of inadequate treatment of effluent.
impact of climate change (extreme weather events, fires, etc.)
The adoption of preventive measures, the revision of operating procedures and the continuous modernization of
systems aims to ensure the uninterrupted and safe operation of the wastewater network and wastewater treatment
facilities, while reducing the Company's environmental footprint through the reduction of energy consumption, the
strengthening of the circular economy and the reduction of the carbon footprint.
Our impacts
Α. SEWERAGE NETWORK
EYDAP is responsible for the construction, operation and maintenance of the sewerage network in its area of
competence, as defined by article 8 of Law 2744/99 as in force today.
The population served is approximately 3,695,000 inhabitants.
The total length of the sewerage network under our competence in 2021 was 8,438 km and in 2022 8,598 km.
The incorporation of the wastewater network of the city of Megara and Nea Peramos on the 1.9.2023 rose the total
length of the wastewater network to 8,716 klm . So our network extends from Agios Stefanos to Salamina and
from Varkiza to Megara and Nea Peramo.
Our aim is to expand the network to areas lacking sewerage.
The term "sewerage network" in the area under EYDAP's competence, for which EYDAP is responsible, refers to the
sewage pipelines, the all-flow pipelines (the old mixed network in Athens city center), the pumping stations, the
pressure pipelines, the overflow shafts and generally any project that aims to the collection and transportation of
sewage to the final recipients.
Pipelines and external branches of sewage systems constructed by third parties are incorporated in the final
sewerage network after acceptance by EYDAP.
Attica's sewerage collection is carried out by rainwater and sewage pipelines. The system is divided (effluent - storm
water pipelines), except from the central area of the city of Athens, where the system is combined (common system
for effluent and storm water).

Graphics
155
On the 3
rd
.2.2023 a Planning Agreement was signed between the Municipality of Athens and EYDAP, under which
EYDAP is assigned with the responsibility to construct sewage pipelines of less than 300 mm in cross-section, as well
as branches for the connections of properties to EYDAP network. This Planning Contract will have a duration of ten
years
According to current legal framework, the responsibility for storm water drainage and flood protection projects, as
well as for the cleaning of drainage shafts, belongs to the Region of Attica and the local municipalities.
Sewers are usually gravity pipelines, but where necessary there are also pressurized pipelines.
Attica's sewerage system after the incorporation of the sewerage pipeline system of the city of Megara and Nea
Peramos includes: 59 pumping stations, mainly along the coastal line of Piraeus and the coast of Saronikos and
Salamina, 3 pumping stations in Thriasio Field, 1 pumping station in the Municipality of Stamata, 1 pumping station
in Adames 8 ay Nea Peramos and 7 at Megara, while new pumping stations are constantly being added from the
secondary sewage networks, the construction of which is under the responsibility of the Municipalities, which are
received by EYDAP.
EYDAP closely monitors the proximity of its installations, especially of the pumping stations to the natural recipients,
in order to intervene timely and prevent cases of environmental pollution from potential overflows.
Wastewater is discharged via the main collectors to the Wastewater Treatment Plants.
Α.1 SEWERAGE NETWORK INSPECTION AND MAINTENANCE
Network maintenance and fault restoration is carried out with continuous and immediate interventions, by highly
trained personnel and the use of appropriate equipment that is constantly modernized and the extensive use of
modern information systems. The prevention and effective treatment of problems is achieved through the use of
modern equipment and the extensive use of modern information systems. More details at eydap.gr.en in section
Company/Sewerage and wastewater treatment/SewageNetwork”
Α.2 . MONITORING OF BREAKDOWNS IN THE SEWERAGE NETWORK
Damage to sewerage network is caused by blockages due to the discharge of unfit materials into the network, such
as rubble, grease and oil and other objects, as well as by the entry of roots from adjacent trees.
Α.3 DIGITAL IMAGING OF ABOUT 80% of the NETWORK which contributes to the rapid response to the problems
encountered.
Α.4 CONTINUOUS MODERNISATION OF EQUIPMENT
In 2023, we received:
3 suction and high-pressure water tanker trucks from wastewater recycling.

Graphics

2 high-pressure water and waste water suction tanker trucks.
Α.5 INSPECTION OF SEWAGE EFFLUENTS FROM INDUSTRIAL AND MANUFACTURING SITES
The specific obligations of professional, industrial and craft activities to discharge wastewater into the sewerage
network in the areas under EYDAP's competence are regulated by the Special Sewerage Network Operation
Regulation in conjunction with the relevant CMDs. EYDAP authorizes the companies, that produce liquid waste in
the context of their production activities, to its legal disposal in the sewerage network and conducts systematic
sampling and tests of the waste entering the network.
Laboratory analyses of the samples are carried out in our accredited laboratories in Akrokerimos and Metamorfosi.
Sanctions are imposed, in case set limits of parametric values are exceeded, as these are defined in the Special
Sewerage Network Operating Regulation.
In 2023, a contract was tendered for the installation of a quality monitoring system for urban and industrial sewage
entering Metamorpfosis WWTP.
Α.6 DEVELOPMENT OF SEWERAGE WORKS
In order to ensure the drainage of all areas under EYDAP's competence, and are currently deprived of sewerage,
EYDAP, in cooperation with the Municipalities, is proceeding with the planning and design of the required
sewerage projects in Attica.
In this context:
Construction of sewerage pipelines in certain areas of EYDAP's competence.
In progress
Construction of connections to properties and secondary sewerage network with the required
manholes in the areas of competence in the North-East and South-East sectors.
In progress
Reconstruction of pressure pipelines in the South-East sector.
In progress
Reconstruction of sewerage network, manholes and property connections in the South-West and
North-West areas of competence.
In the process of contract signature.
The tendering procedures of the projects are particularly lengthy, due to constant amendments to the law and
litigation. As a result, the appointment of the contractor and the signing of the relevant contract takes place after
a long period of time - more than a year in many cases - from the publication of the tender documents.
Β. 5 WASTEWATER TREATMENT PLANTS (5 WWTPs)
The treatment of effluent of EYDAP area of competence, that currently have a sewerage network is carried out at
the 3 Wastewater Treatment Plants (WWTPs) at Metamorfosi Attica (WWTPM), at the Psyttalia Island (WWTPP)
and at the Thriasio Field (WWTPTF).
Since September 2023, EYDAP took under its jurisdiction the operation and maintenance the Megara Wastewater
Treatment Plant and in mid-December 2023 took over the management and the operation of the Koropi-Paiania
Wastewater treatment Plant.
EYDAP's main concern is:
compliance with the environmental conditions in force.
the optimal and uninterrupted operation of the WWTPs, with continuous and proper maintenance.
the continuous modernization of the facilities.
the management of treatment by-products using the most modern methods
compliance with the required outflow quality limits.
compliance with the principles of circular economy and application of sustainable management (production
of biogas and management of the sludge produced as an alternative fuel).
For a detailed reference on this subject, see the 'Circular economy' section of the same report.
In accordance to the published maps of the Ministry of Natural Resources that the Psyttaleia, Metamorfosis and

Graphics
157
Thriasio WWTPs are not located in flood risk areas with a recovery period of 100 years; while the Megara WWTP is
located in flood risk area with a recovery period of 100years.
Β.1 Psyttaleia Wastewater Treatment Plant (Psyttaleia WWTP)
It is one of the largest WWTPs in Europe and worldwide, with a treatment capacity (average design flow) of
1,000,000 m
3
/day of wastewater.
In 2023
the total inflow of sewage was in the order of 240,000,000m
3
the average inflow of sewage is in the order of 660,000 m
3
/day.
Urban wastewater and pre-treated industrial wastewater are discharged into the Psyttaleia WWTP from
the wider area of the Attica basin, except for certain areas where urban waste water is treated at the
Metamorfosis WasteWater Treatment Plant
the island of Salamina.
At Psyttaleia WWTP biological treatment (secondary treatment with nitrogen removal) and drying of the
produced dehydrated sludge is carried out.
The efficiency of the plant, in terms of removal of the total pollutant load, is of the order of 95% or more for
certain pollutants.
The treated outflow from the Psyttaleia WWTP end up directly into the Saronic Gulf.
Psyttalia WWTP ENVIRONMENTAL FOOTPRINT
The energy optimization of the Psyttaleia WWTP and energy saving has been one of the most important objectives
of EYDAP. For this reason, the operation and maintenance contracts attempt to make a special contribution in this
direction.
Detailed reference to this issue in the section ' Climate Change Mitigation Strategies ' of the same Report.
The sludge treatment process produces biogas, which is used as a fuel in the sludge drying plant, instead of natural
gas, while any surplus is used as fuel in engines for the co-production of electricity and thermal energy to meet the
corresponding energy needs of the Facility.
The dried sludge produced is made available as an alternative fuel to cement industries. On average, approximately
40,000 tn are produced annually. The upgrading of the facilities aims at the overall improvement of the operational
processes and the further improvement of energy self-sufficiency of the centre through the increase the biogas
production.
A detailed report on the subject is given in the section " Circular Economy" of the same Report
UPGRADING OF PSYTTALEIA WWTP FACILITIES
In the context of upgrading the facilities, further optimizing the operation of the Plant and in full compliance with
environmental conditions, the following projects are planned to be implemented within the next five years:
Construction of a building for the temporary storage of pre-treatment product bins at Akrokeramos.
Equipment and commissioning of the two inactive dredging tunnels.
Improvement of the overflow pipe at Acrokeramos and landscaping.
Improvement of the collection and treatment of fats and oils in primary sedimentation.
Anaerobic treatment of fats and oils through the construction of two new digesters
NON-STANDARD URBAN WASTEWATER INFLOW
In the context of addressing incidents related to the inflow of wastewater of non-standard urban composition in the
WWTP of Psyttaleia, in 2020, an internationally recognized professor of the Faculty of Civil Engineering of the
University of Patras was assigned to carry out a research project on "Collection, Processing and Analysis of Time
Series of Qualitative and Quantitative Parameters at the Entrance and Exit of Psyttaleia WWTP for the Detection
and Probabilistic Modeling of Emergency Charging Incidents".

Graphics
158
The objective was to understand and quantify the influence of extraordinary loading incidents on the smooth
operation of the plant. The work was completed in January 2022.
ENVIRONMENTAL CONDITIONS
The treatment of the wastewater of the Psyttaleia WWTP, in terms of the requirements resulting from the
Environmental Conditions (EC), has been, over time, completely successful, which is confirmed by the results
announced and posted annually on the official website of the Ministry Of Environment And Energy, as required by
law.
There is, however, a deviation in compliance with the condition relating to the chlorination of the treated outflow
(non-compliance with the provisions of the MD No. Eiv221/1965). This is included for the first time in the 2009
renewal of the Environmental Authorisation Decision of the Psyttaleia WWTP. It should be noted that neither the
studies, nor the corresponding EADs, nor the construction of the Psyttaleia WWTP (A and B Phase) by the Greek
State provided for the construction of a chlorination plant.
On the subject, studies by reputable public University bodies and scientific institutions show that chlorination of the
outflow of treated effluent from the Psyttaleia WWTP to the aquatic environment is not advisable.
In particular they state:
A study by the National Technical University on the issue of chlorination of treated effluent has proved that
"chlorination of the wastewater of Psyttalia is not advisable but should be avoided". This study also showed
that the quality of the bathing waters is of excellent quality.
Reports by the Hellenic Center for Marine Research (HCMR), concerning the results of the monitoring of the
ecosystems of the inner Saronic Gulf and the Gulf of Elefsina, document that there is no impact on the marine
recipient from the operation of the Psyttaleia and Thriassio WWTPs.
The study of the School of Chemistry of the National Kapodistrian University of Athens (NKUA), the Laboratory
of Analytical Chemistry of the Department of Chemistry regarding the issue of the possible addition of chlorine
to the treated wastewater of the WWTPP, concluded that: "the addition of the extra chlorination stage is not
proposed as a strategy for the treatment of the outgoing wastewater of the WWTP of Psyttaleia before its
discharge into the aquatic ecosystem".
In view of all the above, EYDAP has submitted a request to the Ministry of Environment & Energy for the removal,
from the EAD of the WWTP of Psyttaleia, of the clause concerning the obligation to add chlorine to the treated
wastewater of the WWTP of Psyttaleia, in order to formally eliminate this apparently regulatory deviation.
Β.2 Metamorfosis Wastewater Treatment Plant (Metamorfosis WWTP)
It is the oldest wastewater treatment plant and is a reception and co-treatment facility of
urban effluent through a network of sewage collectors and
domestic sewage from areas of Attica that lack a sewerage network
In addition, pre-treated biodegradable industrial waste is disposed at the Industrial Waste Sump of the
Metamorfosis WWTP, which ends up for treatment at the Psyttaleia WWTP.
The WWTP has a treatment capacity (average design flow) of 44,000 m
3
/day of wastewater (20,000 m
3
/day of
urban wastewater and 24,000 m
3
/day of urban sewage).
In 2023
the average inflow of sewage is in the order of 24,000 m
3/
day
(effluent 14,000 m
3/
day and sewage 10,000 m

the total inflow of sewage was in the order of 8,040,000 m
3
(effluent 4,760,000 m
3
και sewage 3,280,000 m
3
).
At the WWTP urban wastewater and sewage are co-treated (secondary treatment) with chlorination of
the treated outflow and treatment and dehydration of sludge.
The pollutant load removal rate, in terms of organic load, is over 99%

The final recipient of the WWTP outflow is the Pyrnas stream, which ends in Kifissos
WWTPM ENVIRONMENTAL FOOTPRINT
The dehydrated sludge is transported to the Psyttaleia WWTP for drying
reference on the subject, in section "Circular Economy”.
The use of the produced biogas, which is a renewable energy source, for heating the sludge of the digestion tanks
and the buildings of the Metamorfosis WWTP, leads to the withdrawal from the use of fossil fuels (e.g. oil) and to
the reduction of electricity consumption for heating buildings. The total energy saving from heating buildings is
estimated at 63 MWh/year.
Our aim is to optimize the operation with:
projects to improve the existing treatment facilities and the facilities at the Tanker Truck Discharge Area
implementation of the particularly important for the region and the residents, in addition to the existing,
deodorization projects
projects for the treatment of biodegradable industrial waste.
projects for further energy utilization of the biogas produced, through the installation of an electricity and
thermal energy cogeneration unit. The implementation period of the projects is estimated at 2 years from the
signing of the Contract, that means, in 2026
As part of the monitoring system and the faster service of the tanker trucks transporting urban and industrial
wastewater entering the Metamorfosis WWTP, an electronic control system (e-pass) was installed in 2018. Vehicles
enter the WWTPM using a prepaid card.
Also in 2023, the installation of an integrated quality control system for all urban and industrial sewage disposed at
the Metamorfosis WWTP was put out to tender, in order to avoid the disposal of unsuitable sewage and to protect
the biological processes of the plant.
Β.3 Thriasio Pedio Wastewater Treatment Plant (Thriasio WWTP)
The Thriasio Pedio WWTP has been operating since 2012 and is the most modern WWTP. It is an integrated solution
to a chronic problem of the inhabitants of the Thriassio Pedio area, thus contributing to the restoration of the
balance of the ecosystem of the Gulf of Elefsina, which has been identified as a sensitive recipient.
The Thriasio Pedio WWTP serves the areas of Elefsina, Aspropyrgos, Mandra and Magoula, with a treatment capacity
(average design flow) of 21,000 m
3
/day of wastewater.
At Thriasio WWTP secondary treatment is carried out with phosphorus and nitrogen removal and disinfection
The removal of the pollutant load is achieved at a rate of more than 95%.
Treated outflow from the Thriasio WWTP ends up directly to Elefsina Gulf.
Measurement of incoming flow at the Thriassio WWTP
Following the actions taken by EYDAP in the Thriassio area, a continuous increase of inflow to the WWTP is observed.
Specifically, according to previous years data : In 2015 the average daily inflow 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, in 2020 it
reached 6,000 m
3
/day ,in 2022 it was 6,330 m
3
/day and in 2023 is in the order of 6.300 m
3
/day.
In 2023, the total inflow of sewage was in the order of 2,300,000 m
3
m

.
Pipelines, 130 km long, for the transfer of sewage to the WWTP, and 3 pumping stations were constructed as part
of the sewerage works in the Thriasio area to comply with Directive 91/271/EEC on urban wastewater treatment.
ENVIRONMENTAL FOOTPRINT OF THE THRIASIO WWTP
The operation of the WWTPT will lead to the elimination of cesspools and the eventual discharge of untreated waste
water into the environment. The dehydrated sludge produced in the WWTPT is transported for thermal drying to
the Psyttaleia WWTPT.

INCREASE IN PROPERTY CONNECTIONS
In order to increase the number of property connections, EYDAP
implemented a program to provide financial incentives to residents of the areas whose wastewater is expected
to be sent to the Thriasio WWTP. This Program was implemented from mid-2014 until 30.6.2019
strengthened, even with financial incentives, the construction of connections in the Municipalities of Elefsina,
Mandra-Eidyllia and Aspropyrgos (2017 and 2018).
As a result of the above actions, combined with parallel actions taken by local Municipalities for the construction of
connections, the service rate of residents increased significantly, estimated at 93.8% (second half of 2022).
The total outflow of treated wastewater for the year cumulatively for all 3 WWTPs is considered equal to the
inflow. For 2023 is 250,259,022 m
3
(685,641 m3/ημέρα).
Β.4 Megara Wastewater Treatment Plant (Megara WWtP)
Recently, in September 2023, EYDAP took under its jurisdiction the operation and the maintenance of Megara
Wastewater Treatment Plant, which was in the ownership of the Municipality of Megara.
The facility is located East-NorthEast of the city of Megara at the location “Shinea Pigadi”. The WWTP receives
sewage through a network of sewage collectors from the city of Megara and New Peramo as well as household
sewage from areas that lack a sewerage network.
Treated effluent are guided through an under-sea pipeline to the aquatic area of the Saronic Gulf, west of Hesonisos
of Ag. Triada at the “Almyre” location and at a depth of 30m. The stabilized dehydrated sludge, since EYDAP got in
charge of the installation, is transported to the Psyttaleia WWTP for thermal drying.
The average daily design effluent inflow is 8,000 m
3
/d.
At Megara WWTP secondary treatment is carried out with nitrogen removal and disinfection.
In 2023 the WWTPM treated in average 1, 900m
3
/d effluent and 90m
3
/d sewage.
Β.5 Koropi-Paiania Wastewater Treatment Plant
In mid-December 2023, the management and the operation of the Wastewater Treatment Plant of Koropi-Paiania
came under the jurisdiction of EYDAP.
The facility has the capacity to treat wastewater equivalent to a population of 99,486 i.c.
In 2023 treated in average 1,750 m3/d of urban effluent
To the already licensed facility is directed or is tto be directed the sewage from the following areas:
Municipality of Paiania as a whole, including Industrial Park of Paiania
the town of Koropi and the settlement of Karellas of the Municipality of Koropi, the Industrial Park of Koropi and
Karella and the Koropi wholesale park included
the southern areas of the Western Regional Ymmittos Avenue of the Municipality of Pallini
the settlement Chamolias of the Municipality of Markopoulo-Mesogaia
Expansion projects of the Koropi-Paiania WWTP are planned, concerning a future new treatment line (2
nd
treatment
line) for the reception of the additional hydraulic and pollutant load of the sewage from the coastal areas of the
Municipalities of Saronikos & Kroppia.
At the WWTP secondary treatment is carried out with phosphorus and nitrogen removal and disinfection.
The treated effluent are directed through an under-sea pipeline to the aquatic area of Chamolia in the Southern
Evoiko Gulf through a tunnel.
C. LABORATORIES FOR CHEMICAL ANALYSIS OF WASTE WATER
Our laboratories are accredited by the National Accreditation System (NSAS) in accordance with ISO 17025 -
Certificate numbers 862-3 ("Akrokeramos Sewage Laboratory") and 856-4 ("Metamorphosis Laboratories").
These tests are carried out on samples of effluent ,wastewater and sludge from:
the WWTPs

the Environmental Inspectors on matters within their competence relating to pollution of the aquatic
environment
In the case of businesses- industries, the parameters examined, their limits and the frequency of sampling are
determined by the relevant legislative framework and the corresponding environmental conditions concerning the
WWTPs.
In 2023, the number of samples analyzed by the laboratories of the Dpt of Laboratory Analysis of Wastewater
amounts to 11,500 with the corresponding analyses reaching 65,000.
Results of industrial wastewater testing through sampling at EYDAP laboratories
Taking into account the results of the inspections and the large number of business using the sewerage network
(over 10,000), it is concluded that, in general, business comply with the requirements of the legislation. It should be
noted that the sanctions imposed are minimal. For the years up to 2020 we refer to 10 companies.
For 2021 the sanctions imposed were 12, while for 2022 the relevant number is 15.
Data for 2023 is not yet available
D. TRAINING OF STAFF
Sewerage personnel working in particularly adverse and unhealthy conditions (inside manholes and pipelines with
the release of gases dangerous to health, etc.) is constantly trained in order to respond to their duties in the safest
and optimal way.
Ε. ASSESSMENT OF THE EFFECTIVENESS OF OPERATION AND MANAGEMENT OF THE WASTEWATER SYSTEM
This is done by developing the following applications and practices, some of which are important innovations in the
operation of the system:
Ε.1. Monitoring of the marine ecosystem of the Saronic Gulf and the Gulf of Elefsina and evaluation of the results,
in collaboration with an independent research organization (HELLENIC CENTRE FOR MARINE RESEARCH -HCMR).
The Hellenic Centre for Marine Research (HCMR), based on contractual agreement with EYDAP, is monitoring the
quality of the ecosystem of the Inner Saronic Gulf and of the Gulf of Elefsina and of the Keratsini Bay, as affected by
the Psyttaleia Wastewater Treatment Plant and the Thriasio Field Wastewater Treatment Plant.
Monitoring started in 2005 and continues to date. The results show a continuous improvement of the ecological
status of the Inner Saronic Gulf and the Gulf of Elefsina, especially at the discharge points of the WWTPs.
Detailed reference to this issue in section "Protection of Marine Environment " of the same report
Ε.2. Publication of the results of wastewater treatment in the National Database of the Ministry of Environment,
Energy and Climate Change.
Quantitative and qualitative characteristics of the inflows and outflows of Wastewater Treatment Plants are
published in the electronic database http://astikalimata.ypeka.gr/ of the Special Secretariat for Water.
The characteristics published are as follows:
Average annual effluent inflow.
Average annual inflow load BOD5.
Annual quantity of dried sludge produced (tn).
Annual quantity of Dry Solids (tn).
Daily values (mg/l) of the parameters: BOD5, COD, TSS, T-N, NH
4
-N, T-P
Access to the database is free for all citizens.
Over time, as can be seen from the results posted in the electronic database of the Ministry of Environment
and Energy, the quality of outflow of EYDAP's Wastewater Treatment Plants is always within the limits set
by the approved Operational Environmental Conditions.
Ε.3 MONITORING OF INFLOWS AND OUTFLOWS at WWTPS BY CONTINUOUS SAMPLING AND MICROBIOLOGICAL
ANALYSIS IN EYDAP LABORATORIES

Graphics

Systematic sampling of wastewater, according to needs and in compliance with the legislation in force, at the inlet
and outlet of the WWTPs, as well as at intermediate stages of treatment, for chemical and microbiological analyses.
The results of the analyses confirm that the limits set by the environmental conditions of the WWTPs are respected.
F. INFORMATION SYSTEMS USE
EYDAP's high requirements in terms of information systems, led the Company to a continuous improvement of the
existing IT applications concerning the SewerageService and the installation of new ones.
G. OVERFLOWS
Wastewater overflow due to heavy rainfall is allowed by the relevant article (clause d.5 par. 5.2, 5.3) of the
environmental conditions of operation of the WWTPP. Based on the data on wastewater flows to be treated at the
Psyttaleia WWTP and on the capacity of the pumping station at the Akrokeramos inlet, it is estimated that the
overflow in 2023, due to flooding, was 2.5* 10

of EYDAP services on the health and safety of citizens
EYDAP'S PLANNING FOR SEWERAGE IN AREAS OF EAST ATTICA 2023
EYDAP planning for the drainage in the regions of East Attica has direct and potential impact on the environment
and on the local community and indirect on the economic and cultural development.
As the company responsible for the provision of water supply and sewerage services in the Attica region, EYDAP
SA has taken substantial action to solve the problem of non-integrated wastewater management, which for many
years has led to environmental degradation, sub-optimal management of the valuable resource of water and the
imposition of fines for non-compliance with European Directive 91/271EEC, regading the urban wastewater
treatment.
EUDAP’s crucial drainage projects built have been designed to operate with state-of-the-art technology, ensuring
the reuse of the treated outflows, in full compliance with the current institutional framework for reuse.
An Environmental Awareness and Information Center will be operating in the premises of the Municipalities of
Rafina-Pikermi and Spata-Artemis, where pilot programs will be implemented for the optimal use of reclaimed
water as well as environmental information and education activities.
The projects are co-financed by the Cohesion Fund and the European Regional Development Fund, through the
NSRF Operational Programs 2014-2020, as well as by the Recovery and Resilience Fund. The financing of the
projects also includes the construction of the external branches, which would burden, based on the current
legislative framework, the owners of the properties that will be served by the new drainage projects.

Β. ENVIROMENTAL BENEFITS FROM THE IMPLEMENTATION OF THE PROJECTS
According to the plan, in the next few years, approximately 400,000 inhabitants of East Attica will be connected to
the sewerage network
The Wastewater Treatment Plants (WWTPs) to be operated by EYDAP S.A. in East Attica (Rafina-Pikermi &
Artemida-Spata WWTP, Marathon WWTP, Koropi-Peania WWTP) will have a reclaimed water production
capacity of about 48,000 m
3
/day.
This capacity can be increased in 20 years (2040) with the construction of the necessary expansion works of
the WWTPs to 75,000 m
3
/day
The annual production capacity of reclaimed water for the irrigation season (April-September) will rise to
8,800,000 m
3
/year in the construction stage, while for a 20-year period (2040) the corresponding capacity
may be increased to 14,000,000 m
3
/year.
Under the assumption that annual irrigation water needs of arable land adjacent to the WWTPs are in the
range of 500-600 m
3
/acre/year - as recorded in the "General Plan for the reuse of the treated effluents of the
WWTPs of East Attica" (EYDAP S.A. E, 2016) - it is possible to irrigate
o at the initial stage around 16,000 hectares of arable land
o in 20 years (2040) about 25,000 hectares
Based on the conclusions drawn from the updating of the above Reuse Master Plan of the East Attica WWTPs and
from the preparation of a “Viability Study of the Management Body for Reclaimed Water of East Attica Region" in
cooperation with the Jaspers Group of the EU, the projects that will be launched in the next period will specify on
the unlimited irrigation of agricultural land in East Attica and necessary technical studies will be prepared.
Β1. Protection of the water resource
The reuse of WWTPs treated effluents is a strategic choice for EYDAP in the design and implementation of these
projects with a significant impact on the remediation and enrichment of the groundwater aquifer and the
conservation of the valuable resource of water.
The maturing actions of the project for the reuse of WWTPs recovered water for irrigation and peri-urban use for
Graphics
164
the benefit of the agricultural cooperative and local societies are in progress.
Informative/awareness actions for local farmers, as the main potential users of recovered water are planned and
have been launched.
The preparation of a viability study for the business plan of the reuse of the treated Outflow of WWTP is in progress
In the context of the Viability Study, the first working meetings were held between EYDAP and local farmers with
particular success. Three meetings were held, at Spata with the representatives of the Agricultural Cooperatives of
Spata, at the Town Hall of Kropia, with the Agricultural Cooperatives of Paiania-Koropi-Markopoulo and at
Marathona eith the representatives of the Agricultural Cooperative of Marathona
The interest parties had the chance to get informed on the recovered water, the technical specifications and quality
controls that the body will carry out, as well as for the potentials and the benefits of the availability of this important
resource.
Discussion was made on the opportunities opened by the possibility of using recycled water for crop irrigation.
Partnerships with the Agricultural University- Pilot Irrigation Application
In the framework of the Company’s strategy for the development of the possibility of irrigation through the reuse of
treated effluents, EYDAP in collaboration with the Agricultural University of Athens developed a pilot application of
irrigation with treated effluents in an experimental field of the University in the area of Mesogeion.
In the pilot application were caarried out
5,000 analyses related to the determination of physicochemical propertied of soils and
1,000 analyses related to the determination of the biometric and biochemical characteristics of wine
and olive plan tissue
The conclusion, after monitoring an irrigation season was particularly encouraging, as it showed that irrigation with
treated effluent under strict quality characteristics, as determined by the legislation, is completely safe and
recommended without indications for avoiding the long term use.
The cooperation between EYDAP and the Agricultural University is to be continued with relevant pilot and research
projects.
Β2. Reducing the energy footprint of projects
The significant reduction of GHG emissions in the region is valued as a major result of the implementation and
operation of the projects.
Provision has been made for the:
Reduction of energy consumption, through the application of new technologies and high-level automation
systems, allowing ther detailed control and optimal regulation of processes, with a positive impact on the
operating costs. The design of the WWTPs provides for the possibility of regulating the operation of the
basic equipment and the continuous monitoring of the operation through a modern remote control -
remote management system (SCADA) in order to reduce energy consumption.
Use of RES to cover part of the energy consumption of the Rafina-Pikermio and Spata-Artemis WWTPs.The
utilization of the produced biogas is planned as well as the installation of photovoltaic systems on the free
surfaces of the WWTP.
Installation of a Small Hydroelectric Station for energy production at the Marathona WWTP
The future WWTPs in East Attica, when in full operation at their manufacturing capacity levels (Rafina-Pikermi &
Artemida-Spata, Marathon & Koropi-Peania WWTPs) and in combination with the above energy saving measures, a
significant reduction of greenhouse gases (GHG) of 20,000 tn CO2/year can be achieved, compared to the existing
situation, i.e. compared to the management of wastewater with private septic/absorption trench systems and the
transfer of the sewage to the Metamorphosis WWTP for co-treatment with urban effluent.
Β3. Remediation of underground aquifer
According to the strategic choice of EYDAP, the treated outflows of the Koropi-Peania WWTP will be reused both
for the irrigation of crops and peri-urban green areas (irrigation of communal municipal areas) and for the
enrichment of the underground aquifer through existing wells and boreholes.
Graphics
165
According to the Watershed Management Plans (Directive 2000/60) and EYDAP studies as well as of other bodies, it
has been established that the underground aquifers in the area of Central Mesogeion (area of the Koropi-Paiania
WWTP) are locally under intensive exploitation and preset strong annual drop in water level (well waterlogging)
seepage phenomena but also nitrate pollution.
EYDAP projects in the area (WWTPS, projects for water reuse, enrichment of the aquifer) have been designed with
the aim to protect and upgrade the underground acquirer
With the realization of the projects, a drastic reduction will be achieved:
In the use of cesspools, most of which are absorptive and to this day burden the groundwater with a significant
pollution load
Pumping from the underground aquifer, thus limiting the risk of salinization of the underground hydraulic
system
Β4. Ecosystem upgrading Protection of Biodiversity
Collection and treatment of communities urban effluent consists of an environmental infrastructure project, aiming
to protect the surface and coastal aquatic ecosystems
Reference is made in section “Protection of Biodiversity” of the same report
C. STRATEGY FOR EXECUTING THE PROJECTS
EYDAP, in the context of the actions for the speedy operation of the sewerage projects in East Attica and the
avoidance of problems and delays resulting from the dispersion of the responsibilities for the construction of the
sewerage projects
adopts a holistic approach to the construction of all seperate parts of the projects,
undertakes the simultaneous construction of the secondary sewerage network and the corresponding
external branches to connect the properties, the responsibility of which, under existing legislation, belongs
to the municipalities,
plans actions, in cooperation with the municipalities involved, to speed up the connection of properties to
the sewerage network with the completion of the construction of the projects,
establishes, in cooperation with the Municipalities, customer service centres for property owners in the
respective areas to provide information and receive applications - with the required documents - for the
construction of external branches to connect their properties to the sewerage network of EYDAP, when this
is in progress.
Customer service centres are already operating in the Municipalities of Peania, Rafina-Pikermi , Pallini, and
Marathona, to facilitate the process of connection to the sewerage network.

2.1.5 EMPLOYEE HEALTH & SAFETY material topic
For EYDAP, in the context of Sustainable Development and the protection of Human Rights, ensuring the physical
and mental health of its human resources is a long-standing moral commitment, as well as an integral part of its
general policy, in accordance with the most recent Health and Safety Policy Statement of EYDAP, which has been
strictly followed since 2014.
The main risks that the Company is called upon to address, with regard to the Health & Safety of its Employees, are
due to the diversity and specificities of the workplaces (administrative services, external workshops, construction
sites, refineries, wastewater treatment plants, etc.), the use of various machinery and tools for a very wide range of
technical work, but also unforeseeable situations such as extreme weather conditions, natural disasters (e.g. fires),
the COVID-19 pandemic, etc.
Our impacts
INTERNAL PROTECTION & PREVENTION DEPARTMENT OF EYDAP (IPPD)
The Employee Health & Safety Management System is determined by the regulatory provisions and internal policies
and regulations as formulated after the identification of potential risks. In accordance with the legislation in force
(Presidential Decree 17/96, Law 3850/2010), EYDAP has established and organized an Internal Protection &
Prevention Department, which is a direct advisor to the Management on health and safety issues.
The Company's Occupational Safety Doctors and Safety Technicians all have an employment contract with a direct
employer, EYDAP, and are not from an External Prevention and Protection Agency. .
CERTIFICATIONS
In 2021, IPPS was certified for ISO 9001:2015 "Quality Management System" and ISO 45001:2018 "Occupational
Health and Safety" (replacing the ELOT 1801:2008 / OHSAS 18001:2007 standard, which was in force until then).
During 2023, IPPD successfully passed the audit by the certification body, without any observations.
TASKS AND RESPONSIBILITIES OF IPPD
Complies with legislative requirements, standards and internal guidelines
Communicates openly and transparently with all stakeholders so that potential risks are identified and
addressed as soon as possible.
Ensures that a culture of health and safety at work is reinforced through messaging, continuous and targeted
training for all employees.
Prepares written Occupational Risk Assessments for each job performed.
Carries out measurements of harmful factors in the workplace.
Prepares specifications for Personal Protective Equipment & Group Protection Equipment.
Records and investigates accidents at work and encourages workers to report near misses to enable preventive
action to be taken to avoid them. To this end, a near miss reporting form has been posted on EYDAP's intranet
'Thalassa', accessible to all employees for completion. It draws up an annual activity report, which records the
observations of the Safety Technicians by activity, as well as the recommendations of the IPPS, for the
improvement of procedures.
Develops a program for the issuance by Occupational Physicians of a Certificate of Fitness to each worker
according to his/her job
Develops a vaccination program for employees.
The risks at work are identified and then through reports of the safety technicians and occupational physicians
in the suggestion books of work technicians and safety physicians that exist in all the facilities of IPPD, the
proposals of IPPD to the management for the prevention of occupational accidents and occupational diseases
are recorded (Law 3850/2010).
POLICY ON HEALTH AND SAFETY OF EYDAP
EYDAP has adopted and applies EYDAP's Policy on Health and Safety (posted on the corporate website eydap.gr)
which sets specific objectives, for which it is committed to making every effort to achieve them, while at the same
time it considers that each employee should also make every effort to fulfil his/her own responsibilities and
obligations, responding to this commitment of the Management.
The Policy on Health and Safety of EYDAP applies to all employees of EYDAP’s facilities without exception,
regardless of the employment relationship under which they are employed.

WORKERS' HEALTH AND SAFETY COMMITTEE (WHSC)
WORKERS' PARTICIPATION IN THE PREVENTION OF OCCUPATIONAL HAZARDS
Direct employees of the EYDAP who consider that their work poses a risk to their safety should address their elected
body, where, among other things, anonymity is respected, in order to avoid reprisals. In particular, in accordance
with the legislation in force (Presidential Decree 17/1996, Law 3850/2010), a Health and Safety Committee of
Employees has been established by the employees, an advisory body composed of elected representatives of the
employees, with the power to identify occupational hazards. In the event of a serious occupational accident, it
proposes measures to prevent its recurrence and, in the event of an immediate and serious risk, calls on the
Management to take the necessary measures, including the shutdown of machinery/installation/production process
Quarterly tripartite meetings are held between the Management, the representatives of the Workers' Health and
Safety Committee (WHSC) and the Internal Protection & Prevention Department (IPPD), in the presence of a Safety
Technician and Safety Doctor. The company encourages open consultation between management and employees
on Health and Safety issues, recognizing that their participation in the process is a fundamental human right, in
accordance with the relevant Human Rights Policy.
WRITTEN OCCUPATIONAL RISK ASSESSMENTS
The Written Occupational Risk Assessment is a basic requirement of the legislation (Law 3850/2010, article 43) for
the prevention of incidents (occupational accidents and/or occupational diseases). The quantification of the risk and
the prioritization of prevention and response measures are carried out according to the methodological guide of the
Hellenic Institute of Hygiene & Safety. The identification of risks is achieved through continuous and targeted
inspections by Safety Technicians and Occupational Doctors.
An update of the Written Occupational Risk Assessment is required whenever a change in the way of work is
observed by the Safety Technicians or indicated by the workers. From 2020, the revision of the Written Occupational
Risk Assessment will be carried out using new, upgraded software, which has been specially developed for this
purpose, offering, among other things, the possibility of full retrieval of the history of versions.
PERSONAL & GROUP PROTECTIVE EQUIPMENT (PPE & GPE)
The updating of the PPE & GPE specifications is done when necessary by the safety technicians and safety doctors
in order to meet the latest European standards.
INSPECTIONS OF WORK AREAS
As every year, in 2023, an annual program has been drawn up by the Internal Protection & Prevention Department
(IPPD) and submitted to the Hellenic Labor Inspectorate for approval, in which a specific number of visits per
establishment by the Occupational Doctors/Safety Technicians, depending on the number of workers employed in
the establishment, is provided for. The main objective of the inspections is generally to provide advice on safety at
work, to suggest unsafe conditions, to investigate occupational or nearoccupational accidents, and to measure
harmful factors (noise, humidity, temperature, radiation, with appropriately calibrated instruments, etc.).
In accordance with the legislation in force, the observations of the Occupational Doctors and Safety Technicians
must in principle be submitted manually in the book approved by the Hellenic Labor Inspectorate, which is kept in
each individual establishment for this purpose. In addition, on the initiative of the Internal Protection & Prevention
Department (IPPD), the reports of the Occupational Doctors and Safety Technicians are also sent to the
Administration in aggregated form at the end of each month, in the form of electronic files, including photographic
material, if appropriate. The evaluation of the reports of the Occupational Doctors and Safety Technicians is also
carried out by their scientific supervisors in the Internal Protection & Prevention Department (IPPD), who also have
the capacity to carry out ad hoc inspections of the workplaces. Also, at the end of each year, an annual report is
prepared by the IPPD and sent to the Administration, summarizing the main findings of the Occupational Doctors
and Safety Technicians
INVESTIGATION OF INCIDENTS
All notifications of occupational accidents are also communicated within 24 hours to the Internal Protection &
Prevention Department (IPPD) (apart from Hellenic Labor Inspectorate), so that the latter can immediately
investigate each incident. The actions taken by the Internal Protection & Prevention Department (IPPD) include,
inter alia: an autopsy at the place where the incident took place,interviews with the parties involved, preparation of
a report by the competent Safety Technician, analysing the the causes of the accident, sending the written report to
the management, proposal of measures to avoid the occurrence in the future
A detailed record is also kept by Internal Protection & Prevention Department for each industrial accident, based on
both the ISO 9001:2015 and ISO 45001:2018 quality standards, while the data in this record is also subjected to
statistical processing, in order to determine, among other things, quantitative parameters relating to health and
safety performance. .

OCCUPATIONAL MEDICINE
In 2023 it was established by EYDAP
a specific procedure which allows for a change of working environment, voluntarily by workers, if there are
health reasons. The procedure also involves the active participation of the Internal Protection & Prevention
Department and, in particular, the Occupational Doctors who receive the request of the employee wishing to
transfer for health reasons and give their opinion on it, without however disclosing specific health reasons and,
more generally, any medical information that constitutes potentially sensitive personal data.
A full eye examination was carried out on all employees of EYDAP, with the speciality of driver, as well as on
those employees who hold a licence for occasional driving, in order to update their medical certificates of
fitness for this activity.
the Internal Protection & Prevention Department planned and initiated the performance of specialized medical
examinations of those workers (water and sewerage) who may have been exposed to asbestos, in order to
prove as an occupational disease in EYDAP The results of these examinations revealed a number of pulmonary
and other pathological findings (at a rate commensurate with the generally high average age of workers in
EYDAP), but none of these were associated with occupational disease.
were updated (after the expiry of three years, as required by law) and new certificates of suitability were issued
for a total of 625 employees of EYDAP
the digitisation of the certificates of fitness and individual medical certificates of all water and sanitation
workers was carried out.
as many vaccinations as indicated by the Occupational Doctors were carried out (72 in total. New recruits 10
and old employees 62 of which 12 tetanus and 60 Hepatitis).
OCCUPATIONAL DISEASES
During 2023, specialised medical examinations were scheduled by Internal Protection & Prevention Department and
carried out for those workers who may have been exposed to asbestos. The results of these examinations revealed
certain pulmonary and other pathological findings (at a rate commensurate with the generally high average age of
the employees at EYDAP), but none of these were related to an occupational disease caused by the asbestos to
which they were exposed as a result of their work.
EMPLOYEE SAFETY TRAINING
In 2023, it was carried out by the Internal Protection & Prevention Department
the health and safety training program for workers, in person.
educational leaflets were distributed
targeted messages were sent to employees, via e-mail, on critical issues (such as unsafe conditions in specific
workplaces, prevention of heat stress, during the summer period, etc.),
every effort was made to instill a corporate culture of health and safety
A detailed record is also kept by Internal Protection & Prevention Department , with details of the employees
who took part in each individual training activity, in accordance with the requirements of the ISO 9001:2015,
and ISO 45001:2018 quality standards.
EMPLOYEE HEALTH COVERAGE
EYDAP provides full health coverage to its employees through a self-sufficient Service, which is staffed by doctors
and paramedical staff of various specialties.
Detailed reference is made to the section on "Labor Practices" of the same Report
ACCIDENTS AT WORK
According to the legislation, an industrial accident is defined as the death or incapacity for work of the insured
person, caused by a violent incident that occurred during or because of the performance of work (during the
employee's transit to the place of work and during his/her return to his/her place of residence). Accidents at work
of contractor personnel are excluded from the count, as they are counted to the employers with whom these
workers have signed contracts.

Clarifications:
The frequency ratios of occupational accidents have been calculated by assuming the total number of man-
hours worked to be equal to 200,000.
The numerical data in the Table are derived from the record of occupational accidents kept at the Internal
Protection & Prevention Department, in accordance with both ISO 9001:2015, and ISO 45001:2018 quality
standards.
The criterion for classifying an occupational accident as serious has been taken as the absence of a worker from
work for a period of 15 days or more
A severe consequences accident at work is one that results in a serious injury from which the worker cannot or
cannot be expected to fully recover to his or her original state of health before at least 6 months have elapsed
The total number of accidents at work shall include road accidents caused during journeys on official business,
as well as road accidents occurring when workers are going to or leaving their place of work, and within a period
of 1 hour of the start or end of their working hours respectively.
The results of the table refer to all employees (permanent employees, part-time cleaning contractors, 8-month
contract employees, 6-month and 2-month contract students, trainee lawyers, NSRF students) with an
employment contract in which EYDAP S.A. is designated as the employer.
In 2023 there is one death of a direct employee within his/her working hours and within the workplace of
EYDAP, and it is pending classification by the Single institution for social security.
2.1.6 SECURE CUSTOMER SERVICE
AFFORDABLE TARIFF
For EYDAP, continuing to provide high quality water supply and wastewater services at an affordable price for
consumers, serving customers through structured and digital processes, is part of our business continuity and
growth.
RISKS: customer debts, customer economic capacity, reduction of available resource due to climate change, loss of
resource due to network failures, with a concomitant loss of customer confidence.
Our impacts
The Company's efforts to ensure uninterrupted access to the Water Supply / Sewerage Services in order to provide
the necessary goods to the customer and ensure the Company's business resilience are continuous. The existence
of a tiered tariff helps to limit the wasteful use of water and safeguard the resource in order to ensure our company's
uninterrupted operation. Moreover, it helps to reduce our environmental footprint.
Α. CUSTOMERS
In 2023, we refer to a total of 2,257,414 water connections.

RECRUITMENT
The recruitment process to meet the Company's needs is always carried out on the basis of the relevant legal
framework through the Public Recruitment Service. The restriction of recruitment due to Law no. 3833/2010,
has resulted in a constantly decreasing number of employees due to retirement.
In order to reduce the risk of difficulty in meeting the Company's growing needs, two (2) tenders (1K/2018 and
4K/2018) were announced for the recruitment of 300 people of various specialties
with an open-ended contract. The process resulted in a number of resignations and the ASEP was requested to
make a replacement for those who resigned.
In 2023, 6 persons were recruited with an open-ended contract from the above notices.
The need for new specialized knowledge, the expansion of the Company's field of activity (integration of new
areas into the water supply and sewerage network, construction of new projects in East Attica), made even more
urgent the need for immediate further strengthening of the existing staff. In 2021, the Ministry of Interior
approved the Company's request for the recruitment of 145 persons (30 workers and 115 of various specialties)
from the shortlists of the 1K/2018 and 4K/2018 Competitive Calls of High Staff Selection Board. In 2023, the
recruitment lists of 30 posts of the category of Labourers, 33 posts of Secondary Education of various
branches/specialties and 72 posts of the category of University Education and Technological Education of various
branches/specialties, respectively, were published in the Official Gazette from the runners-up of the above
mentioned notices, on a first-come-first-served basis.
Thus, in 2023, 30 workers were recruited from the 4K/2018 runners-up and 20 people of various skills from the
1K/2018 runners-up.

vacancies in the organizational structure (Positions of Responsibility) are advertised internally and the positions are
filled through internal procedures in which the Company's permanent employees, who meet the requirements set
out in each advertisement, are eligible to participate. The procedure involves the completion of a psychometric test
by the candidates followed by skills exploration stage conducted by a team of internal interviewers trained in this
regard. Employees who participate in the process are placed on the Staff Register to fill vacancies for positions of
responsibility in the organizational structure.
In parallel with this work and in order for all the Company's executives to be included in the Staff Register, the same
internal skills screening process is also carried out for the Heads of all Executive General Divisions and Independent
Departments, who have not participated as candidates in any of the internal calls.

internal procedures were implemented, only five (5) positions were filled, leaving two (2) vacancies. Four (4) Head
positions were filled by executives who for the first time took on a position of responsibility and one (1) Director
position was filled by an executive who previously held a Head of Department position.

The KPI referred to in the first subparagraph excludes from its numerator the part of the net turnover derived from
products and services associated with economic activities that have been adapted to climate change in line with
Article 11(1), point (a) of Regulation (EU) 2020/852 and in accordance with Annex II to Delegated Regulation (EU)
2021/2139, unless those activities:
(a) qualify as enabling activities in accordance with Article 11(1), point (b) of Regulation (EU) 2020/852 or
(b) are themselves Taxonomy-eligible and aligned.
b. Key performance indicator related to capital expenditure (CapEx KPI)
The proportion of CapEx referred to in Article 8(2), point (b), of Regulation (EU) 2020/852 is calculated as the
numerator divided by the denominator as specified in points 1.1.2.1 and 1.1.2.2 of Annex I of the Delegated
Regulation (EU) 2021/2178, as amended.
Denominator
The denominator covers additions to tangible and intangible assets during the financial year considered before
depreciation and any re-measurements, including those resulting from revaluations and impairments, for the

activities are outsourced that are necessary to ensure the continued and effective functioning of such
assets.
Numerator
The numerator equals to the part of the capital expenditure included in the denominator that is any of

to Article 10(3), Article 11(3), Article 12(2), Article 13(2), Article 14(2) or Article 15(2) of Regulation (EU)
2020/852 and provided that such measures are implemented and operational within 18 months.
Where the operational expenditure is not material for the business model of non-financial
undertakings, those undertakings shall:
a) be exempted from the calculation of the numerator of the OpEx KPI in accordance with point 1.1.3.2
of the Annex I of the Delegated Regulation 2021/2178 EU and disclose that numerator as being equal
to zero,
b) disclose the total value of the OpEx denominator, as calculated above,
c) explain the absence of materiality of operational expenditure in their business model.
The numerator includes the part of OpEx referred to in the first paragraph of this point that contributes

small hydroelectric power stations in the locations of Kirfi, Eliconas, Kithaironas, Mandra of the Mandra of Mornos Aqueduct, and
the small hydroelectric power station in Evinos; and (b) has installed a photovoltaic station (PV), power 1.9712 MW, in its facilities
in the Municipality of Acharnes, in order to proceed with disposal of the produced electricity.



2. NEW STANDARDS, INTERPRETATIONS AND AMENDMENTS TO EXISTING STANDARDS

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 01/01/2023.
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 amendments do not affect the consolidated Financial Statements. 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 amendments do not affect the consolidated Financial Statements.
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 amendments do not affect the consolidated Financial
Statements. The above have been adopted by the European Union with effective date of 01/01/2023.
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 amendments do not affect the consolidated Financial Statements. The above have been
adopted by the European Union with effective date of 01/01/2023.

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 Contractsand 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
amendments do not affect the consolidated Financial Statements. The above have been adopted by the European Union with
effective date of 01/01/2023.
Amendments to IAS 12 Income taxes”: International Tax Reform Pillar Two Model Rules (effective
immediately and for annual periods starting on or after 01/01/2023)
In May 2023, the International Accounting Standards Board (IASB) issued amendments to IAS 12 “Income Taxes”: International
Tax ReformPillar Two Model Rules. The amendments introduced a) a temporary exception to the requirements to recognise
and disclose information about deferred tax assets and liabilities related to Pillar Two income taxes and b) targeted disclosure
requirements for affected entities. Companies may apply the temperorary exception immediately, but disclosure requirements
are required for annual periods commencing on or after 1 January 2023. The amendments do not affect the consolidated Financial
Statements. The above have been adopted by the European Union with effective date of 01/01/2023.
Amendments to IFRS 16 “Leases: Lease Liability in a Sale and Leaseback” (effective for annual periods
starting on or after 01/01/2024)
In September 2022, the IASB issued narrow-scope amendments to IFRS 16 “Leases” which add to requirements explaining how a
company accounts for a sale and leaseback after the date of the transaction. A sale and leaseback is a transaction for which a
company sells an asset and leases that same asset back for a period of time from the new owner. IFRS 16 includes requirements
on how to account for a sale and leaseback at the date the transaction takes place. However, IFRS 16 had not specified how to
measure the transaction when reporting after that date. The issued amendments add to the sale and leaseback requirements in
IFRS 16, thereby supporting the consistent application of the Accounting Standard. These amendments will not change the
accounting for leases other than those arising in a sale and leaseback transaction. 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 01/01/2024.
Amendments to IAS 1 “Classification of Liabilities as Current or Non-current” (effective for annual
periods starting on or after 01/01/2024)
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. However, in October 2022, the IASB issued an additional
amendment that aim to improve the information companies provide about long-term debt with covenants. IAS 1 requires a
company to classify debt as non-current only if the company can avoid settling the debt in the 12 months after the reporting date.
However, a company’s ability to do so is often subject to complying with covenants. The amendments to IAS 1 specify that
covenants to be complied with after the reporting date do not affect the classification of debt as current or non-current at the
reporting date. Instead, the amendments require a company to disclose information about these covenants in the notes to the
financial statements. The amendments are effective for annual reporting periods beginning on or after 1 January 2024, with early
adoption permitted. 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 01/01/2024.
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

255



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 IAS 7 “Statement of Cash Flows” and IFRS 7 “Financial Instruments: Disclosures”:
Supplier Finance Arrangements (effective for annual periods starting on or after 01/01/2024)
In May 2023, the International Accounting Standards Board (IASB) issued Supplier Finance Arrangements, which amended IAS 7
Statement of Cash Flows and IFRS 7 Financial Instruments: Disclosures. The IASB issued Supplier Finance Arrangements to require
an entity to provide additional disclosures about its supplier finance arrangements. The amendments require additional
disclosures that complement the existing disclosures in these two standards. They require entities to provide users of financial
statements with information that enable them a) to assess how supplier finance arrangements affect an entity’s liabilities and
cash flows and to understand the effect of supplier finance arrangements on an entity’s exposure to liquidity risk and how the
entity might be affected if the arrangements were no longer available to it. The amendments to IAS 7 and IFRS 7 are effective for
accounting periods on or after 1 January 2024. 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 21 The Effects of Changes in Foreign Exchange Rates: Lack of Exchangeability
(effective for annual periods starting on or after 01/01/2025)
In August 2023, the International Accounting Standards Board (IASB) issued amendments to IAS 21 The Effects of Changes in
Foreign Exchange Rates that require entities to provide more useful information in their financial statements when a currency
cannot be exchanged into another currency. The amendments introduce a definition of currency exchangeability and the process
by which an entity should assess this exchangeability. In addition, the amendments provide guidance on how an entity should
estimate a spot exchange rate in cases where a currency is not exchangeable and require additional disclosures in cases where
an entity has estimated a spot exchange rate due to a lack of exchangeability. The amendments to IAS 21 are effective for
accounting periods on or after 1 January 2025. 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
Statement of Compliance
The financial statements have been prepared in accordance with the International Financial Reporting Standards (IFRS).


Basis for Consolidation
The Consolidated financial Statements of the current as well as of the previous period, include the parent company and its
subsidiary “NISON EYDAP DEVELOPMENT S.A.”.
The annual Financial Statements of the subsidiary company “ISLANDS’ EYDAP DEVELOPMENT S.A.”, audited by Certified Auditors
Accountants, are available on the Internet at the company’s website under the domain name www.eydapnison.gr .
Subsidiaries are all the companies which are managed and controlled directly or indirectly by the parent Company - either through
the majority holding of the companies’ shares to which the investment has been made or through their dependence on the know-
how, which is provided to them by the Group. Subsidiaries’ financial statements are included in the consolidated financial
statements from the date of control accession until the date that the control ceases to exist.
During the acquisition of the subsidiary the respective receivables, liabilities as well as any potential liabilities are assessed at their
fair value. In case that the cost value is greater than the fair value, the respective difference is recognized as goodwill.
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.

The Notes on pages 246 307 form an integral part of these Financial Statements
256






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.

257

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.
In order to include accrued not invoiced revenue in the turnover of the reporting period of the financial statements, the Company
makes two categories of provisions:
provision for invoiced revenue (the revenue has been counted and invoiced after the reporting date), and
provision for not invoiced revenue (the revenue has been counted and invoiced until the reporting date
In essence, the above revenues concern provisions that largely depend on the quantities of water consumed. Based on the use
of estimates, the actual amounts ultimately invoiced might differ from those projected.
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 discounts/ 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 re-measures 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

259


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.
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 Companys 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 when 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 systematic and 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.
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.
Government grants for staff retraining are recognized in the income statement during the periods required to meet the
corresponding related costs and are presented as a deduction.
For the non-monetary government grants (networks delivery, Psitalia island, emission allowances) the Company has chosen as its
accounting policy recognition of both the grants and the related tangible and intangible assets at nominal value (instead of fair
value). In particular, for emission allowances, which the Company receives free of charge, the net liability method is applied, under
which a liability for emissions is recognized in the financial statements when emissions of pollutants occur in excess of the related
allowances granted to the Company. At the reporting date, there has been no reason to reassess a related liability.

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.

261



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 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
• 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.

Subsequent to initial recognition, internally generated intangible assets are carried at cost less accumulated amortization and
accumulated impairment losses on the same basis as separately acquired intangible assets.
Intangible assets acquired in a business combination
Intangible assets acquired in a business combination are identified and disclosed separately from goodwill when they meet the
requirements of the definition of an intangible asset and their fair value can be measured reliably. The cost of such intangible
assets is their fair value at the date of acquisition.
Subsequent to initial measurement, intangible assets acquired in a business combination are carried 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.



Graphics
The Notes on pages 246 307 form an integral part of these Financial Statements
263




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.

Receivables ( Miscellaneous advances)
Mandatory expropriation complies with the procedure stated in Law 2882/2001 (Α΄17) "Mandatory Expropriation Code" - as
amended and effective, in particular with article 280 of Law 4364/2016 (Α΄13), adding the provision of article 7A of the above
code which concerns implementation of projects of general significance to the country's economy - in conjunction with Law
1068/1980 (article 28 Expropriations), which applies in addition to the provisions of Law 2744/1999, governing EYDAP SA
operations.
The unit price of the expropriation compensation is determined in accordance with article 7A, as well as the temporary and final
unit price is determined by the competent Court of Appeal, in accordance with Law 2882/01 on mandatory expropriations.
The amounts are awarded to the beneficiaries who will be recognized by a court decision (after the expropriation decision) and
until they are awarded to the beneficiaries, they will remain with the Deposits and Loans Fund.
Until the issuance of the Decision determining the final unit price of the expropriated area, the relevant funds remain in the
"miscellaneous advance payments" and upon its issuance, they are transferred to the project they concern.
It is noted that the Company implements water supply and sewerage projects in its areas of responsibility.

Inventory
Inventory is 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.
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:
• 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
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.
3. Provisions for pending judicial cases relating to labor issues.
4. Provisions for Other Receivables
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. REVENUE
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


Graphics
The Notes on pages 246 307 form an integral part of these Financial Statements
267
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 million is agreed. For 2023 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.
It is noted that, by virtue of the decision of the Board of Directors of EYDAP Fixed Assets No. 17/8.8.2023, the extension of the the
EWSS operation and maintenance service assignment agreement (SLA) was approved, with the same terms, for a period of 6
months, i.e. until June 30, 2024.

The change in turnover is mainly due to:
· the increase in consumption by 0.6%, i.e. an increase in water and sewerage revenue by approximately 6.5 million and the
positive effect of the reduction of revenue cancellations by approximately € 2.5 million compared to the same period last year
· the decrease in water and sewerage revenues of approximately € 1.0 million
· the slight increase in revenues from sale of electricity of approximately € 52 k and in other revenues of approximately € 33 k.
Financial income increased by approximately 4.5 million (note 10). The Company's financial income as of 31 December 2023
amounted to € 17,806 k compared to € 13,264 k in the same period last year. This change of € 4.5 k is mainly due to the increase
in interest income from bank deposits.
Other operating income, which mainly includes income from legal expenses, income from the deposit of letters of guarantee and
other other miscellaneous income, did not show a significant change and amounted to 3.1 million, the same as in the
corresponding period of the previous year.

13. 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).

Other intangible assets concern expenses for the purchase of software and other intangible fixed assets, which are expected to

depreciated over a three-year period whereas with regard to the other intangible fixed assets, the Company reviews their
economic life on regular basis.
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
specifically defined in Article 10 of this contract
(2) the relevant contract of Article 4812/2021, following which EYDAP was assigned operation and maintenance of the EYS with
an initial term of three years with the possibility of extension for another six months.
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 Greek State, EPEYDAP, and the consideration paid for
the intangible right of exclusive supply of raw water amounting to Euro 87,500 k was determined. The cost of acquiring the


Graphics
The Notes on pages 246 307 form an integral part of these Financial Statements
276
intangible right is subject to amortization corresponding to the duration of the commitment, the contract, the supply of the raw
water. 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. As at 31.12.2022, the book value of the
intangible right stands at Euro 74,375 k.

16. 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 changes in fixed assets of the Group and the Company for FYs 2023 and 2022 are presented in the table below as follows:

23. 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 269.0
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”, 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:

Therefore, the balance of trade receivables and contractual assets impaired after the provision for impairment, has been settled
at approximately € 169.9 million in the current period.
As of 31.12.2023, in order to effectively manage its credit risk, the Company made a provision for impairment of receivables for a
total amount of approximately € 99.1 million.

Due to the large number of customers (approximately 2,084,879 as of 31.12.2023), 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 4978/2022), the Company calculates the
relevant interest charged on the overdue amounts at the time of their payment.
The interest rate for calculating interest has been fixed by No. ΔΠΕΙΣ 1198598 ΕΞ 31.12.2013 Decision of the Minister of Finance,
as amended and in force by No. A. 1121/3.8.2023 Decision of the Minister of National Economy and Finance (Government Gazette
5009B'/09.08.2023). In addition to the above, it charges interest at a rate of 3% and 6% to NPAs, the State and local authorities in
accordance with the effective provisions (Law 4607/2019, N, 3463/2006), as applicable.
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.

Loans and Advances to Personnel:
The Company provides the personnel with zero interest loans, short-term payroll advances free of interest, cash facilities and long-
term interest bearing loans. The amount of 4,579 k concerns the short-term part of the loans granted to personnel. The long-
term part which as of 31.12.2023 amounted to € 5,332 k is included in the balance of the long-term receivables (Note 20).
Greek State’s participation in the mandatory coverage of the deficit of the special lump sum account:
The amount concerns Greek State’s obligation based on Law 2939/6.8.2001 to cover the deficit of the special lump sum account
for end of service indemnity, concerning employees who retired and employees who worked for the Company until 25th October
1999. The obligation in effect concerns an overdue amount payable from the Greek State from 01.07.2013 - 08.08.2013
(publication date of Law 4179/2013). Considering the passage of time, the Company made an equal provision for impairment.
Miscellaneous advances:
The item " Miscellaneous Advances" mainly includes advances for compensation of expropriated land plots, totaling € 7.5 million,
following the issuance of a Decision of the Ministry of Infrastructure and Transport (Government Gazette). From the amount of
Euro 7.5 million, the amount of approximately Euro 6.7 million was transferred to the item "Long-term Receivables" (Note 20) due
to the delay in the competent Court of Appeal issuing a decision determining the final unit price of the expropriation compensation
in accordance with article 7A, to Law 2882/01 on mandatory expropriations.
The accumulated provision for doubtful receivables amounts to € 746 k. The corresponding provision formed last year amounted
to € 805 k.
Receivables from the Special Fund for Employment and Vocational Training (LAEK) Educational Programs:
The Human Resources Training Department submitted a request to collect the subsidy after payment to the Unified Social Security
Fund (EFKA) of LAEK the employer's contribution as a beneficiary body, making a provision for the relevant income. The issuance
of the repayment circular of the Manpower Employment Organization (OAED)/LAEK is delayed and in combination with a
retroactive change in the contribution rate, the Company made a provisions for an amount of Euro 578 k versus Euro 795 last
year.
Employees’ claim according to the BoD decision 19389/25.10.2017 and 21087/30.11.2022:
A small group of employees claimed their salary through interim proceedings without the cut of Law 4024/2011. Pursuant to the
decision of the Court of First Instance of Athens, EYDAP SA with the decision of the Board of Directors No. 19389/25.10.2017,
provisionally paid the relevant amounts, forming a receivable amounting to Euro 3.7 million.
The Board of Directors of the Company, following its decisions no. 19389/2017 and 19459/2017 and for the purpose of its
compliance with the decisions regarding the Interim Measures of the Single Member Athens First Instance Court, and in particular
under the threat of their forced execution after the exhaustion of the available remedies aids, finally paid the amounts concerning
the period 2013 - 2018 without the discounts under Law 4024/2011.
Following the same decisions of the Board of Directors, the company expressly reserved its right to recover the excess
remuneration paid applying any legal means.

The subsequent court decisions of the Court of Appeal finally rejected the lawsuits and claims of 131 employees regarding the
above matter, however, the submitted request of the Company for the return of the amounts paid was also rejected.
Following the above development, the Company contacted the employees regarding the matter of the return of the above
amounts and sent letters to them in September 2021 requesting the return of the specific amounts they collected in execution of
the Interim Measures decisions, which they ignored.
The Board of Directors in its decision no. 21087/30.11.2022, decided on the out-of-court resolution of the issue with the warning
of return of the amount by the employees in a certain time before the filing of the lawsuit. It is noted that the amount of the
company's claim, in case of employee departure, is withheld from their compensation. According to the above decision of the
Board of Directors, the amount of approximately Euro 497 k was recovered in 2023 (with the reimbursement of the amounts due
from 19 employees).
Taking into account the relative outcome of the case, the provision for impairment amounted to approximately Euro 1.5 million
versus approximately Euro 1.8 million last year.
Receivables from the Greek State for sickness contributions for new entrants (from 01.01.1993) to the Social Insurance Institute
(IKA):
Law 2084/1992 and Min. Decision Φ2/16/2517/475/2003 defined the way of provisioned the State contribution to the social
insurance bodies for those entering the IKA insurance for the first time as from 1.1.1993. In application of the prescribed
procedure, EYDAP sends to the General Secretariat of Social Insurance of the Ministry of Labor, at the prescribed time intervals,
computerized statements of collected sickness contributions certified by the Board of Directors of the Company in order to issue
the payment orders and to be paid by the Greek State.
The Greek State used to regularly pay the relevant contributions to the Company for a number of years until the second quarter
of 2009, when it stopped the payments. The company filed two lawsuits against the Greek State in order to compel it to pay the
relevant amounts. The first lawsuit pertaining to the amount of € 1,956 k, concerns the period from the third quarter of 2009 to
the financial year 2015, while the second, pertaining to amount of € 855 k, covers the financial years 2016 - 2018. Regarding the
Lawsuits, in 2022, decisions of the Administrative Athens First Instance Court no. 9886/2022 (Department 5th Three-member
Court) and 18068/2022 (Department 31st Three-member Court) respectively were issued, which rejected the legal remedies.
Taking this result into account, the Company made an equal provision.
The amount of the accumulated provision for impairment as at 31.12.2023 stands at Euro 8.434 k from approximately Euro 8,019
k as at 31.12.2023, as analyzed above.

26. SHARE CAPITAL
EYDAP was established in 1980 pursuant to Law 1068/1980 and following the merger of two water and sewerage utilities of 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
nominal value of € 0.60 per share.
The Regular General Meeting of Shareholders held on 25.06.2021, approved: Α) the increase of the share capital by
capitalization of a part of the shares premium account in the amount of €24.495 k with an increase in the nominal value of the
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.
Following the above, the Company's share capital currently amounts to Euro 63,900 k, divided into 106,500,000 shares of nominal
value of Euro 0.60 each.

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”.

29. 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 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.
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.

32. CONSUMERS’ GUARANTEES
The amounts of € 19,312 k on 31.12.2023 and of € 19,109 k on 31.12.2022 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.

33. 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. (Company),
and the memorandum of understanding dated 27.04.2022, the Company recognized the intangible exclusive right to supply raw
water for the period 2021-2040. The relevant reference is made in Note 15.
The consideration paid for the intangible exclusive right to supply raw water was set at Euro 87,500 k plus VAT, i.e. Euro 108,500
k. In the period 2021-2023, part of this obligation was offset with the Company’s receivables from the External Water Supply
System for water supply services and system maintenance, amounting to Euro 93,000 k. As a consequence, the amount of this
obligation is set at Euro 15,500 k on 31.12.2023. The relative liability was transferred and included in the suppliers item of
operating short-term liabilities at 31.12.2023.

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.
5. An Addendum was signed between EYDAP, the Greek State, and EYDAP Fixed Assets
In June 2023, the tripartite Addendum to as of 2.2.2022 Agreement was signed between EYDAP, the Greek State, and EYDAP
Fixed Assets. The agreement defines performing works on the Aqueduct Mornos - Marathonas, Kleidi - Dafnoula Section.
Under this agreement, the implementation of an important project to upgrade the External Water Supply System of Attica is
promoted.
6. In its letter no. 1170/08.08.2023, EPEYDAP informed EYDAP SA of the unilateral extension of the contract for the operation
and maintenance of the External Water Supply System (EWS) under the same terms, for an additional period of six (6) months,
until 30 June 2024.

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.

40. 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 use the methodology for measuring the impairment of financial assets in accordance with IFRS 9.

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).
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 addressed through 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

(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) Risk of Climate Change
EYDAP addresses climate risks as an opportunity to transition to a more sustainable, low-carbon future and implements mitigation
measures:
Formulation of a strategy to improve energy efficiency and reduce the carbon footprint
Implementation of water demand management and leakage reduction programmes to ensure rational and sustainable
management of water resources. Replacing old water meters with new 'smart' water meters of state-of-the-art
technology. Network rehabilitation and replacement of old pipelines with new pipelines made of advanced materials
compatible with the natural environment.
Circular economy practices, launching wastewater reuse projects at the East Attica Wastewater Treatment Plant for
irrigation of peri-urban green areas, industrial and municipal purposes.
Use of technologies to improve the efficiency of water and wastewater treatment plants
Alternative water resources for irrigation use such as exploitation and development of the Adrian Aqueduct
Ensuring that every effort is made to save energy and resources in all its operations, actively contributing to the reduction
of greenhouse gas emissions
Implementation of zero tolerance European and Greek regulations and standards, new and existing environmental
specifications in the design of water supply and sewerage projects
Selecting materials and machinery with modern environmental standards. Monitoring and optimizing the cyclicality of
the materials used. Keeping products and materials (including raw materials) in the life cycle for as long as possible, and
treating waste as a secondary raw material that can be recycled for processing and reuse (circular economy).
Electric vehicles extending the potential to replace part of its fleet with electric vehicles to contribute to low greenhouse
gas emissions
Upgrading and modernizing its buildings and facilities with new building materials and energy systems.
The Company ensures and plans contingency management scenarios that may arise due to climate risk. It recognizes the way
each of its organizational units operates, and has included in the risk register of the Risk Management Framework the risks against
which it must be shielded to effectively respond.
In relation to the last year's commitment to apply the TCFD recommendations, due to the incorporation of these recommendations
into the new IFRS/ISSB international standards, the Group is in the process of reviewing the adoption approach in combination
with ESRS.
(h) EWS failure risk
EYDAP and all the other involved bodies had recognized and evaluated the risk of unsafe water supply in Attica due to failure of
the external water supply system in the unifying aqueduct, owned by the State.
It is estimated that potentially arising damage in this area will cause a temporary deficit of 30-40% of Athens water supply.
On August 4, 2022, the Ministry of Infrastructure and Transport sent a letter to EYDAP in which it is stated that EYDAP is expected
to be assigned immediate priority projects for the EWS, with a budget of Euro 78 million (including VAT) in accordance with Law


Graphics
The Notes on pages 246 307 form an integral part of these Financial Statements
306
4412/16 and the terms of the contract signed as at February 2, 2022. However, the Ministry had not determined the way of
financing the projects, while the relevant contract with EYDAP has not been signed yet either.
In order to avoid the effects of this risk, in March 2023 EYDAP sent a request to the competent Ministries for the specification of
the financing method and the necessary conditions for the implementation of the necessary improvement projects.
In the letter, the Management sent in April 2023 to the supervising ministry, following a relevant meeting attended by the
representatives of EYDAP, EYDAP Fixed Assets, Ministry of Transport and Infrastructure, Ministry of Environment and Energy, it
was communicated that the fastest and most feasible solution to proceed as soon as possible with the implementation of the said
projects is to conclude a contract between EYDAP S.A. and EYDAP Fixed Assets. The relevant directions of the supervising ministry
are expected to be issued directly.
Under article 7 "Raw Water Supply Obligation", of the effective contract with the Greek State:
"The State is obliged throughout the term of the Contract to supply the Beneficiary with Raw Water in accordance with the terms
of this Contract and in any case based on the criteria set out in Articles 8 (Quantitative Characteristics) and 9 (Qualitative
Characteristics) of this Contract."
Consequently, in the event of failure to supply EYDAP with raw water, the financial loss falls in particular on the Greek State, which
has a contractual obligation to provide EYDAP with raw water. EYDAP's risk mainly concerns its corporate reputation. EYDAP's
assessment is that, if the above-mentioned implementation of the necessary projects starts as soon as possible, this risk will be
minimized.

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 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. SIGNIFICANT EVENTS
New Independent Regulatory Authority
On March 28, 2023, the new Law 5037/2023 was published (Government Gazette 78/Α΄/28-3-2023) "Renaming the Greek
Regulatory Authority for Energy (RAE) to the Regulatory Authority for Waste, Energy and Water (RAWEW) and expanding
its scope with responsibilities over water services and urban waste management, strengthening water policy -
Modernization of the legislation for electricity production from RES through integration of EU Directives 2018/2001 and
2019/944 - Special provisions for renewable energies and environmental protection" .
Law 5037/2023 (Government Gazette A' 78) transferred the supervision of EYDAP to the Ministry of Environment and Energy,
while the supervision of water services and municipal waste management was assigned to the Regulatory Authority for Waste,
Energy, and Water (RAWEW).
Council of State decisions
On March 20, 2023, the 7 & 8/2023 decisions of the Tripartite Compliance Council of the Council of State were published, under
which the with which the Council of State ruled that the executive and legislative authorities under articles 114 and 115 of Law


Graphics

307
4964/2022 did not comply with the decisions of the Council of State Plenary 190 & 191/2022, which was ruled the transfer of the
shares of EYDAP and EYATH from the State to the Superfund unconstitutional.
Subsequently, the Council of State ordered the Ministry of Finance to take all the necessary actions, within eight months at the
latest, in order to return the shares of EYDAP and EYATH to the State.
EYDAP undertakes the obligation that when it receives the relevant notification, it will immediately proceed with the necessary
actions.

2 INDEPENDENT AUDITORS REPORT
INDEPENDENT AUDITOR’S REPORT
To the Shareholders of the Athens Water Supply and Sewerage Company (EYDAP S.A.)
Report on the Audit of the Separate and Consolidated Financial Statements
Opinion
We have audited the accompanying separate and consolidated financial statements of the Company
EYDAP S.A. (the Company) which comprise the separate and consolidated statement of financial position
as at December 31st, 2023, separate and consolidated statements of comprehensive income, changes in
equity and cash flows for the year then ended and a summary of significant accounting policies and other
explanatory information.
In our opinion, the accompanying separate and consolidated financial statements present fairly, in all
material respects, the financial position of the Company EYDAP S.A. and its subsidiaries (the Group) as at
December 31st, 2023, 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
The turnover of the Company and the Group
amounted for the year ended 31/12/2023 to €
351,6 mil., (€343,3 mil. for the year ended
31/12/2022).
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-
invoiced 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 31/12/2023 the trade receivables of the
Company and the Group amounted to €
169.9 mil. including accumulated impairment
loss allowance of € 99.1 mil. (€ 169,8 mil.
and € 99,6 mil. as at 31/12/2022).
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.
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 23 to the separate
and consolidated financial statements.
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 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
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 and reconciliation of the data

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.
Given the size (approximately 293,4 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
according to IAS 19 are recorded in Note 29
to the financial statements.
Company's Management to the
external actuaries, regarding the
Company's personnel.
Evaluation, with the assistance of a

consultant, of the actuarial
assumptions and the calculations of
the actuarial study as of 31/12/2023.
Sample based 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 29 to the financial

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 Requirements” section of our Report and Statements of the Members of the
Board of Directors, but does not include the separate and consolidated financial statements and our
auditor’s report thereon.
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.

Graphics
312
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.
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.

Graphics
313
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,
