The Public Works Authority ‘Ashghal’ has announced the completion of the Third Expansion project in the Industrial Area Sewage Treatment Works, through which the plant’s capacity to treat sewage flows was increased by an additional amount of 30,000 m3/day, bringing the total capacity of the plant to 90,000 m3/day.
The sewage treatment plant is located about 2 km southwest of the industrial area in Doha. It started operating in 2014 with an initial capacity of 12,000 m3/day. Ashghal has implemented the first and second expansions in 2015 and 2017 to bring its capacity up to about 60,000 m3/day.
In this context, Eng. Abdulrahman Mohammed Al Sulaiti, Head of Treatment Plants and TSE Network Projects Section in the Drainage Networks Projects Department at Ashghal, stated that this project is part of Ashghal’s plan to implement a series of expansions for the sewage treatment plant in the Industrial Area. The expansion aims to keep pace with the remarkable increase in the population and urban growth in the industrial area and its infrastructure.
Eng. Abdulrahman Al Sulaiti has confirmed that the third expansion brought the capacity of the treatment plant up to 90,000 m3/day, and thus the rate of increase in the plant’s capacity since its start until today has reached 650%. He added that Ashghal's plan includes the implementation of an additional expansion if needed in the future to reach a capacity of 120,000 m3/day.
The Project Manager, Eng. Nayif Abdulghani Alkathiri, Drainage Networks Projects Department, added that the increase in the plant's capacity is planned to meet the increasing demand for sewage treatment, as it will increase the number of house connections to workers’ accommodations, which will be connected to the sewage network. The project will also serve the new areas around the Industrial Area with the drainage network, including areas that belong to the Ministry of Energy and Industry, commercial areas and the extended areas to the North and South of the Industrial Area, in addition to other areas that are planned to be provided with services in the future.
He explained that the sewage treatment plant in the Industrial Area uses advanced treatment techniques to produce treated water that conforms to the highest international environmental standards. Sewage water will be treated with disc filters, ultrafiltration system, UV treatment system and other technologies to ensure the production of high-quality treated water with minimal human intervention.
The project also included the construction of a sludge treatment system, an odor control system, in addition to increasing the capacity of the treated wastewater pumping to 90,000 m3/day.
As part of Ashghal’s constant efforts towards supporting local manufacturers, a variety of local materials were used in this project, including GRP tank pipes, emergency sinks, street lighting poles, road works and paint, all electromechanical construction material, consumable construction materials, reinforced steel, structural steelwork, electrical power control panels and other materials.
It is also mentioned that the third expansion project was awarded the Golden Award from Royal Society for the Prevention of Accidents (RoSPA), in honor of the project's performance in the health and safety field in 2021. All project works were completed without any injuries, which reflects Ashghal’s vision to apply the highest safety standards in project sites, as safety specifications are one of the most important standards of the authority for the qualification and accreditation of contractors to ensure the protection of workers from occupational risks.
