The Public Works Authority announced that the second expansion of the Doha South Sewage Treatment Works won the MEED Quality Award 2016, in the energy and water field. The project was selected amongst many entrants for the MEED Quality Awards, which is one of the most important infrastructure awards programmes at the regional level.
On this occasion, the Public Works Authority organised a celebration to honour the project contractor, “Larson and Tubro” and “Galfar Al Misnad” Joint Venture, in the presence of Eng. Khaled Saif Al Khayarein, Manager of Drainage Networks Project Department in Ashghal. During the ceremony, a certificate was presented to the representatives of the project contractor, “Larson and Tubro” and “Galfar Al Misnad” Joint Venture for completing 7.7 million man hours without accidents. The contractor achieved this milestone through committing to the health and safety standards on site that are adopted by Ashghal in all its projects.
The Doha South Sewage Treatment Works, which was completed at the beginning of this year, is one of the most prominent treatment plants in the country, with a capacity to treat 241 million litres of sewage water per day. The plant features advanced techniques such as Ultra Filtration, which produces high quality treated water that exceeds the standard set for the quality of water, and which is pumped through treated water networks to be used for irrigation and cooling purposes. The plant is also run by advanced systems and electronic programmes with minimum technical intervention by engineers and workers.
The Doha South Sewage Treatment Works receives raw sewage from the various pumping stations in Doha city, where it enters the primary treatment facilities stage which removes stones and solid materials. After primary treatment, secondary biological treatment is conducted, which includes a number of stages and technologies which are implemented to purify the water to reach the stage of ultra-filtration using membrane technology, which produces high-quality treated water.
The second phase of expansion implemented at the plant included the construction of three electricity substations, six pump houses, one storm water lagoon and one treated sewage effluent (TSE) Lagoon. Water treatment operations are run through a network of 15 km plant piping.
Throughout the implementation phases of the project, there was a complete commitment to the health and safety standards on site, which Ashghal makes sure all contractors are abided with. Those standards included training the workers and vaccinating them against the health hazards of working in a live sewage treatment plant.
The project contractor achieved a milestone in terms of safety especially that the works involved hazards posed by the work environment and the nature of the project.
