Narrative Description of Project:

Due to continuous wars and economic sanctions, sewage system of Baghdad, comprising sewers, pumping stations and sewerage treatment plants, has been severely affected and these facilities are not able to take care of generated wastewater.  Especially in Karkh Sewer District, about 556,000 m3/day of the wastewater is generated, of which only about 205,000 m3/day is being treated by the existing Karkh Sewage Treatment Plant (STP). The captioned project intends to expand the capacity of Karkh sewage treatment plant and to rehabilitate and replace 9 pumping stations in Baghdad. The project also includes the preparation of detailed architectural and engineering design for different buildings such as Administration Building, Warehouse, Powerhouse, Disinfection Facility, and Wastewater Recycle Facility.
