Aims of the project I:

•Check selected elements of the WATECO-guidance draft, mainly:

Description of situation in Corfu

• Corfu Island dealt with as a river basin, but without a river!

• Water for all uses: groundwater origin• High seasonality of water demand (tourism),

water supply constant in time• Groundwater deterioration due to:

- natural reasons (presence of gypsum and natural sea water intrusion)

- human activity (groundwater overexploitation)

Description of the pilot area Corfu• Area: Corfu island, 587 km2

(including surrounding small islands: 632.5 km2) • Administrative division: 12 municipalities (including surrounding islands: 16) • Municipal Water Suppliers: 9 for Corfu island• Permanent population: 112.848 (year 2000),

all connected to public water supply system• Most of the population is living in the city and

the coastal areas

Description of the pilot areaGround water resources availability:• Estimation of deposits: 114*106 m3 (44% in karst units,

21% in Triassic conglomerates, 35% in intergranular series)

• Due to sea water intrusion and gypsum presence, only a small percentage is of adequate quality for water uses

• Indication of quality factors (mg/l) (water supply in Corfu city):

Results: Importance of water uses

• Main use: household and tourism • Significant additional use: agriculture• Not significant: “industry” (rather:

manufacturing)

Overall: water related activities are strongly affected by geomorphological characteristics of Corfu

13

ecologic.de

19.6.2003, Hellenic Water Week: Testing the WATECO-Guidance: Corfu Pilot Project

Results: spatial economics• Detailed view of Ropa

valley• Primary use of water

for tourism: Only the golf terrain is irrigated

14

19.6.2003, Hellenic Water Week: Testing the WATECO-Guidance: Corfu Pilot Project

Results: Projecting trends for 2015Crucial element of the 3-step-approach:• Large gap between the requirements of the

guidance document and reality• only estimates available for future water

demand on 2038, based solely on demographic changes/estimates of per head consumption

• large amounts of new data needed• out of existing information, no estimation on

the baseline scenario can be given

15

ecologic.de

19.6.2003, Hellenic Water Week: Testing the WATECO-Guidance: Corfu Pilot Project

Results: Assessing cost recovery

A number of sub-steps (information) is needed for this estimate, focus here on:

• water pricing of municipal water supply, pricing in

agriculture

• costs of water supply

--> issues of charges, fees, taxes, relevant public

subsidies/grants, cross-subsidisation, environmental

costs: not considered

16

ecologic.de

19.6.2003, Hellenic Water Week: Testing the WATECO-Guidance: Corfu Pilot Project

Results: Water pricing issuesNo aggregated information available, primary data:• Public water supply of the 12 municipalities: different

tariff systems• In some cases: special tariffs for entrepreneurial uses• In 2 cases: special tariffs for agricultural use; 2 local

irrigation organisations have tariffs covering operation costs

• In order to compare prices, different consumption values were assumed: wide variation of prices for public supply, most with a gradual price increase for higher consumption, some cases show a decrease

17

ecologic.de

19.6.2003, Hellenic Water Week: Testing the WATECO-Guidance: Corfu Pilot Project

Results: cost of water supply

• very limited information on agriculture

• public water supply: centralised data does not

exist, local water suppliers asked for information

• no estimation on cost recovery can be given:

- no estimates on environmental/resource costs

- information on financial costs of water supply

was fragmentary

Evaluation• A non-virtual exercise to be used as a

framework for the economic analysis in Greece, but: time and financing constraints, therefore not complete “testing”

• Linking economic to hydrogeological information (Annex II WFD) is important

• WATECO-guidance useful, but requires a lot of economic understanding

• A good starting point for understanding the need of improvement of the water management structures in Greece

19

19.6.2003, Hellenic Water Week: Testing the WATECO-Guidance: Corfu Pilot Project

Evaluation

Large efforts needed in Greece for delivering the

Economic Analysis in time, due to limited:

• data availability and quality;

• centralised availability of data;

• awareness of the WFD and water-economic

capacities in water administration

• methodological knowledge

Support by:

Recently commissioned program for the development of water resources management systems (divided regionally according to the water districts), aimed at the development of Water Resources Management Plans (duration: 36 months)

--> some support for the economic analysis can be expected from these studies

21

ecologic.de

19.6.2003, Hellenic Water Week: Testing the WATECO-Guidance: Corfu Pilot Project

The axes for improvement

• Accelerate the establishment and staffing of the regional “competent authorities” as well as the central water institution (reduce overlaps between ministries)--> will happen soon• Provide adequate resources and capacities for conducting the economic analysis (2004: at the central level)• Establish a clear “plan of action” including strict deadlines (“critical path”)

22

ecologic.de

19.6.2003, Hellenic Water Week: Testing the WATECO-Guidance: Corfu Pilot Project

The axes for improvement

• Improve data availability and quality (primary data)• Urgent need for raising awareness and inform local water administrations about the WFD requirements

--> strong political support will be needed!
