As part of its efforts to facilitate the availability of treated water, the Public Works Authority (Ashghal) has built a filling station for treated sewage effluent (TSE) at the Doha West Sewage Treatment Plant.
The objective is to supply TSE directly from the plant to the users, an Ashghal statement said on Tuesday. This step comes as part of Ashghal’s initiatives to provide TSE filling stations in various strategic locations in Qatar to encourage the industrial, construction, fodder agriculture and cooling sectors to use treated water instead of potable water.

The filling station for treated sewage effluent (TSE) at the Doha West plant can fill up to 20 tankers simultaneously with a capacity of 20 cubic meters of treated water, while the plant produces 275,000 cubic meters of TSE per day

The project includes design, supply, installation, construction and operation of the TSE tanker filling station at the Doha West Sewage Treatment Plant, which is strategically located at the crossroads between Salwa Road and Al Majd Road.
The filling station for TSE at the Doha West plant can fill up to 20 tankers simultaneously with a capacity of 20 cubic metres of treated water. It takes about 12 minutes to fill a tanker.
The plant can fill up to 40 tankers per hour, 960 tankers per day and more than 350,000 tankers per annum. The Doha West plant produces 275,000 cubic metres of TSE per day and in 2020 it produced approximately 100 mn cubic metres treated water.
Ashghal operates 24 wastewater treatment plants across Qatar. These plants produce TSE that conforms to international and local specifications. The uses of TSE include irrigation of green areas and beautification of roads, fodder agriculture, cooling system, washing sand used in construction and roads and construction projects.
The treatment process begins with the primary stage of removing sludge, sand and oils, followed by the secondary stage of removing nutrients, then the tertiary advanced filtering stage using sand and microns (UF 0.02 micron) and then the sterilisation process by chlorine and ultraviolet rays.
The drainage water flows by gravitational force from the facilities to the lifting stations, from where the water is pushed to the treatment plants. The water enters through various treatment stages to finally emerge as TSE, suitable for many uses.
Ashghal’s two wastewater treatment plants in West Doha and Lusail provide the service of filling treated water to tankers. Many advanced systems and technological solutions are used, such as smart meters, leakage detection devices, tankers tracking systems and lately the systemised filling stations.
Ashghal provides all the information about the treated water service through its official website and a customer zone portal
