Project Description
Küçüksu Wastewater Pretreatment Plant protects the natural assets along the shoreline between Beylerbeyi and Anadolu Hisarı, Küçüksu and Göksu Creeks, and Elmalı Dam. Thanks to the advanced ozonation system at the facility, the odor issue has been completely eliminated. The plant treats an average daily volume of 640,000 m3 of wastewater generated in the Üsküdar, Ümraniye, Çekmeköy and Beykoz districts. The treated wastewater is then discharged through a marine outfall measuring 2,172 mm in diameter and 363 meters in length into the Bosphorus at a depth of 67 meters, into the undercurrent of the Black Sea.
