"Climate Changes Impact on Water Resources With Emphasis on Potable Water"

Objectives of the Workshop:

To highlight the importance of climatic changes on water resources. Obvious climate changes impacts are an increased risk of flooding, increased intensity of extreme weather events and decreased water availability in many water-scarce regions. These impacts will directly or indirectly affect both water resources and water supplies. Managing water resources under changing hydrological conditions poses a new challenge to European water sector and particularly to water operators. EUREAU has an active interest in water and climate. Recent events regarding this subject increase that interest. Among the objectives are included the followings: The impact of climate change on water resources (quantity and quality); examples of coping mechanisms and adaptive strategies; and developing a draft strategy for EUREAU.

EUREAU: EUREAU is the European federation of national associations of drinking water suppliers and waste water services, representing thousands of water utilities that provide water services to around 405 million people across Europe. Our members borrow water from the natural cycle, treat it when necessary, distribute it as clean and safe drinking water, collect it as waste water and give it back to the water cycle as treated waste water. EUREAU’s members are deeply committed to sustainability in all aspects of their activities and fully support the goals and principles of the European water framework directive. Besides, they reflect the full diversity of the European water services sector and represent both public and private operators.(

Hellenic Union of Water and Wastewater Enterprises: The Hellenic Union of Water and Wastewater Enterprises was established in 1989. It is located in the city of Larissa. The Union has 175 DEYA (Municipal Enterprises for Water Supply and Sewerage) members all over Greece. They have been established by the Law Ν. 1069/80 since 1980. The major objectives of the Greek Enterprises are the urban water supply and the management of wastewaters (collection, treatment, and disposal).  The Union serves as consultant and represents DEYAs to the Greek Government. It has been involved in several national and EU projects, mainly pilots. The Union of DEYA is run by an eleven member Board of Management consisted by Mayors. The Union became full member of EUREAU in 1993.(

Central Union of Municipalities and Communities of Greece: The Central Union of Municipalities and Communities of Greece is a legal entity of the private law and constitutes the principal institution that represents the first level of local authorities in the country.The foundation of the Central Union was decided in 1927 and was promulgated by presidential Decree in 1931.The aims of KEDKE is the promotion of all issues concerning local authorities,the promotion and support of each local authority, the collection of information that might enhance cooperation between local authorities, the cooperation  with the Central Government on every subject that will contribute to the growth and decentralization of the local authorities,the provision of technical support to the local authorities and the participation in European and International Organizations representing local interests.(

Municipal Enterprise for Water and Sewage of Chania: The Enterprise was founded in 1981 in order to undertake the responsibility for the potable water, the sewage and the rain collection systems, as well as the wastewater treatment plant for the city of Chania. The legal entity of the enterprise is a private company that is beneficial to the public and of non-profitable character. All the capital of the enterprise belongs to the municipality of Chania. The admi­nistration board consists of eleven members, nine nominated from the City Coun­cil, one from a social organization and one representative of the 134 employees of the company. The potable water and sewage collection system covers the needs of the citizens of the municipality of Chania and partly of the municipality of Therissos. The wastewater treatment plant treats the sewage of the municipalities of Cha­nia, Therissos, Akrotiri, Souda, Eleftherios Venizelos.
