Mubasher: The Qatari Public Works Authority (Ashghal) announced the completion of 65% of the works in the Doha South Sewage Infrastructure Project.
Ashghal said that it has achieved 1.5 million man-hours without loss time injury (LTI) since it started implementing the project in December 2016.
According to the authority’s statement issued on Sunday, 20 old pumping stations in residential and commercial areas in Doha South will be eliminated upon project completion.
The project comprises the construction of a 16 kilometer main trunk sewer, divided into three segments, Eastern, Northern and Western. This is in addition to the design and construction of 11 shafts that will be used to excavate the main tunnel. The main trunk sewer will convey the sewage flows through pumping stations to the existing Doha south treatment works.
The project also includes the construction of seven lateral interceptor sewers with a length of about 24 kilometers, which will convey flows from areas in the centre of Doha to the main tunnel.
