Water Supply and Sewerage

We build water transmission lines, reservoirs and distribution networks, as well as sewerage, stormwater drainage and wastewater treatment plants.

The first entries on our project list are the drinking water schemes undertaken in 1986 for İller Bankası (Bank of Provinces) in Osmancık (Çorum) and Çakırhöyük (Adıyaman). Since then we have built drinking water systems in Giresun, Samsun, Düzce and Malatya, wastewater treatment plants in Karaman and Adıyaman, and sewerage networks in Horasan (Erzurum) and Uluborlu (Isparta).

Section 1 of the Ömerli – Şeyhli – Darıca – Pendik transmission line, 13,583 m of Ø2235 mm steel pipe laid for İSKİ (Istanbul Water and Sewerage Administration), is the largest-diameter pipeline we have built. Abroad, we completed the Göygöl water intake and the Ganja transmission line in Azerbaijan, as well as drinking water and sewerage lines in Ganja itself. In Afghanistan, work on the Kabul water supply project is in progress.

Scope of work

  • Spring catchments, water intakes and deep wells
  • Transmission lines, pumping stations and pressure-break chambers
  • Reinforced-concrete water reservoirs and chlorination units
  • Drinking water distribution networks and service connections
  • Sewerage networks, collector lines and manholes
  • Stormwater drainage systems
  • Biological wastewater treatment plants
