Engineering consultant: HGBD Arabia Consulting Engineers

Description: The Riyadh Water Supply Project (RWSP) is a design, build, operate and maintain programme to produce about 220,000 cubic metres a day of treated water for the city. NWC faced a tough challenge in completing the project to meet the extra demand during the summer of 2013. Although the project was similar to others that took 18 months to execute, it was completed in just six months. The scheme has 46 deep wells with depths of 1,700-2,500 metres, 46 cooling towers and 46 water treatment plants. There are also storage tanks, booster pumps, pipelines for raw and treated water, an electricity generation system and a supervisory control and data acquisition (Scada) system. The new water treatment plants are connected directly to the existing network.
