The Public Works Authority, Ashghal, is implementing the fifth expansion of Doha West wastewater treatment and recycling plant, to meet the increasing population in Doha and protect water resources. The latest expansion increasing the plant’s capacity from 174,500 cubic metres per day (cu m/day) to 280,000 cu m/day will be completed in third quarter of 2017, according to earlier reports.
The treatment plant, in Al Sailiya, began operating with a capacity of around 20,000
cu m/day, and due to the population increase, the plant was expanded several times until its capacity reached about 174,500 cu m/day after the fourth expansion.
Currently, the plant receives approximately 200 cu m/day. A reception sewage tank terminal with a capacity of up to 50,000 cu m/day was constructed as an alternative to Al Karaanah landfill, which required the implementation of a fifth expansion to increase the plant’s capacity to 280 thousand cubic metres per day.
The fifth expansion works include secondary treatment, sludge treatment and drying, tertiary treatment, construction of treated water pumping station, and the construction of a new system to sterilise treated water without affecting the natural environment surrounding the treatment plant.
Most of the recycled water is used to irrigate green spaces and market gardens and to replenish groundwater, which helps to significantly improve the management of the resource.
Meanwhile, Ashghal is going on with its community outreach programme which aims at promoting awareness about Ashghal’s projects across the country. Recently, 60 students from the Middle East International School visited the Doha West Sewage Treatment Works (STW) project. Students attended a presentation, in which they were briefed about the details and benefits of the project.
