With a view to meet the medium-term water
need of İstanbul, the Yeşilçay project has
been designed to convey water from the
Göksu and Çanak rivers in the Ağva region
60 km away from Ömerli Dam. At the first
stage, a volume of 145 million m³ of water
has been secured annually by Sungurlu and
İsaköy regulators constructed on these rivers.
The Sungurlu and İsaköy dams will be to be
constructed on the rivers at a future date, thus additional 190 million m³ water will be secured to
the city. The total amount of water to be conveyed to the city will be 335 million m³.The water
collected by Sungurlu and İsaköy Regulators goes to İsaköy Pumping Station, the biggest of its
kind in Europe. Then the water will go to the surge tank by means of the 2,560 m raising main.
The water then is carried by gravity through the pipeline to the Darlık and Kömürlük tunnels,
and reach the Emirli treatment plant, the construction of which has already been completed.
Thus, the demand for drinking water for an additional population of approximately 1.5 million
inhabitants will be met. The first stage of the system was inaugurated in May, 2003.
