Al Aweer Sewage Treatment Plant

About Al Aweer Sewage Treatment Plant

The Al-Aweer sewage treatment plant is located 25km away from the city centre and receives sewage from both domestic wastewater and septage. Optimal operation of the plant is essential for the city as it performs both tertiary wastewater treatment for irrigation reuse and sludge treatment for reuse as a soil fertiliser. The plant was initially designed with a capacity of 130,000m³ a day, which was later upgraded to 260,000m³ a day. A secondary biological treatment facility was also installed, which featured two new flow splitting chambers and three aeration tanks. Additional anoxic treatment facilities were added to improve the sludge setting characteristics. The tertiary biological treatment unit was installed with a flow-splitting chamber, a new big-filter recirculation pumping station, and two new tertiary settling tanks. The upgrade also included modifications to yard piping and replacement of biological filters.
