Yenikapi Waste Water Treatment Plant

Fisia Italimpianti (Unit of the Salini Impregilo Group)


ISKI, Istanbul Water and Sewerage Administration

Total value:
€ 57 million

Fisia Italimpianti, a unit of the Salini Impregilo Group and a global leader in water treatment and desalination facilities, has won a €57-million contract to build a plant that will treat waste water in Istanbul, Turkey.

Once completed, the plant will treat 450,000 cubic metres of waste water per day, a volume equal to the sewage produced by two million residents.

Fisia Italimpianti, whose 90 years of experience has built desalination plants that serve a combined total of more than 20 million people worldwide. The first contract won in 2016 involves modernising and expanding a waste water treatment plant in the Atakoy neighbourhood of Istanbul, allowing Fisia Italimpianti to consolidate its role as developer of projects that assist in improving the environment.

Fisia Italimpianti and its joint-venture partners Alkatas and Alke will take 36 months to build the plant in the city’s Yenikapi neighbourhood for Istanbul Su ve Kanalizasyon Idaresi (ISKI), a municipal water utility.

The two plants – one in Atakoy and the other in Yenikapi – will be capable of meeting the needs to treat sewage water produced by 30% of the population of Istanbul.

Capacity: 2,000,000 inhabitants equivalent
Preliminary treatment: 750,000 m3/d
Biological stage: 450,000 m3/d
