Tunnelling complete on west Doha South Sewage scheme

DOHA, January 8, 2018

Qatar’s Public Works Authority Ashghal has completed the tunnelling works in the Western branch of the main trunk sewer of its Doha South Sewage infrastructure project.

The project site witnessed the breakthrough of the tunnel-boring machine into the wall of the tunnel shaft, in the presence of Abdulla Hamad Al Attiyah, Ashghal president assistant and Khalid Saif Al Khayareen, drainage networks projects department manager, along with a number of officials and engineers from the project’s consulting and contracting companies.

This major milestone represents the completion of one of the three main branches forming the main trunk sewer of Doha South Sewage infrastructure project, which will convey the sewage flows through pumping stations to the existing Doha South Treatment Works.

Al Attiyah said that the tunnel extends five kilometres underground reaching several areas including Al Sadd, Al Maamoura, and Salwa Road, up to the Doha South Sewage Treatment Works.

He noted that the achievement shows that Ashghal is still making progress in all its roads, expressways, buildings projects as well as the infrastructure and drainage projects that are being carried out deep underground. He added that these achievements prove that the State of Qatar is able to move ahead and deliver projects with the required quality and as scheduled.

Al Khayareen said that the Western branch that was completed today is one of the three parts of the Main Trunk Sewer which will serve Al Sadd, Al Maamoura, Umm Ghuwailina, and Al Matar areas. He pointed out that the main tunnel will withdraw the drainage water in a smoother way via gravitational factors to get it to the treatment plants, which will contribute to eliminate around 20 old pumping stations.

The western branch of the main trunk sewer, which was completed on January 7, stretches from Al Thumama Area to Salwa Road through Abu Hamour Area, with a length of about 5 km, representing about 30 per cent of the total length of the main tunnel. The tunnelling works, which started in the beginning of January 2017, took a period of 12 months at an average rate of 13.7 m per day. – TradeArabia News Service
