The Athens Water Supply and Sewerage Company (EYDAP SA), is the largest company in Greece operating in the water market.

EYDAP SA supplies approximately 4.000.000 inhabitants of Attica with potable water, through an extensive network that includes 1.796.500 metered connections and a total length of  7.940 km. The sewerage sector similarly serves 3.300.000 inhabitants, with a total network length of 5.800 km.

EYDAP was founded in 1980 with the enactment of Law 1068/1980, after the merging of the Hellenic Water Company (E.E.Y.) and the Sewerage Organization of Athens (O.A.P.).

In 1999, after the passing of Law 2744/1999, EYDAP SA took on its current legal form, with the primary fixed assets of the company passing into the ownership of the newly formed “Fixed Assets Company EYDAP NPDD ”, (NPDD is an Greek acronym which translates as “Legal Entity – Public Sector”) , a company remaining in the public sector. The Fixed Assets Company EYDAP NPDD owns the dams, the reservoirs, the external raw water aqueducts and pumping stations, as well as all other installations that ensure the secure transfer of water until it reaches the Water Treatment Plants. However, based on a signed agreement between EYDAP and the Hellenic Republic in November 1999, EYDAP SA continues to operate the aforementioned works on behalf of the Fixed Assets Company EYDAP NPDD.

In January 2000, EYDAP SA went public on the Athens Stock Exchange.

The Law 2744/1999 and its modifications define the Corporate Objectives, as stipulated in the Joint Ministerial Decision of the Ministries of National Economy, Finance and the Environment, Physical Planning and Public Works. These objectives are as follows:

The provision of water and sewerage services, as well as design, construction, installation, operation, utilization, management, maintenance, expansion and renewal of water supply and sewerage systems. In addition to the above activities, the objectives include the pumping, desalination, treatment, storage, transfer, and distribution of all kinds of water. In addition, the works and procedures of collection, transfer, storage, treatment, as well as the management and distribution of the waste treatment products are included.

EYDAP’s area of jurisdiction was originally defined as the greater metropolitan area of Athens in Law 1068/1980, which initially founded the company. In conjunction to the above, in accordance to Law 2744/1999, EYDAP has the exclusive right to offer water supply and sewerage services in the geographical region of its jurisdiction. This right is undeniable and non transferable. The duration of this right, as well as its renewal, are regulated by the Agreement signed by the Hellenic Republic and EYDAP. This Agreement was signed December 9th, 1999 and is valid for 20 years with the option of renewal.

It is important to mention that Law 2744/1999 and the Joint Decision of the Ministers of National Economy, Development, Environment, Physical Planning and Public Works, allows EYDAP the ability to expand its activities to regions inside or outside of Attica. As a precondition to expanding its activities, EYDAP must first examine and ensure the effectiveness of the investment, as well as ensure that the Company has the necessary funds for this purpose, so as it is in position to fulfill its obligations.

In order to ensure the water supply of the metropolitan area of Athens, EYDAP procures raw water from the Greek Government, who has agreed to provide it from appropriate sources and to give it to EYDAP. In accordance to Law 2477/99 and the 1999 agreement between EYDAP and the Hellenic Republic, up until the year 2004, the price of the raw water provided by the Greek Government will be off-set by the cost of the services provided by EYDAP for the maintenance and operation of the fixed assets that belong to Fixed Assets Company EYDAP NPDD.
