Erzurum Water and Sewerage Administration (ESKİ)

The objective of the Project is to provide a wastewater management system for the city of Erzurum, thereby reducing the pollution load in the Karasu River and ensuring that wastewater discharge is carried out in compliance with EU and Türkiye standards. Thus, the improvement of the wastewater and stormwater collection systems was achieved, and the drinking water, stormwater, and wastewater systems of Erzurum were enabled to operate more efficiently.

After the needs of the network were identified, the planning of wastewater treatment and collector requirements was carried out, and the projects were prepared. International technical assistance was provided to the Contracting Authority for the works tender, and the construction processes were initiated.

The Project covers the supervision of all designs and works of the plant, including construction, reinforced concrete, electrical, mechanical, and process components (Design and Build – FIDIC Yellow Book), as well as the construction of 24.8 km of wastewater network, 6.2 km of wastewater collectors, 2.2 km of box culvert stormwater drainage and stream rehabilitation, 2.47 km of pressurised wastewater pipeline, and the supervision of the design and construction of one wastewater pumping station

Within the scope of the Project, feasibility studies, design, and preparation of tender dossiers (FIDIC Red Book) for the drinking water distribution network of the entire Erzurum city centre were carried out. In addition, studies on non-revenue water and unbilled consumption were conducted, and through the training provided, the institutional capacity of Erzurum Water and Sewerage Administration was strengthened.
