Sewage project for south Doha to be completed by 2019

One of the important benefits of the project is the gravity based main trunk sewer that will link a number of areas in the south of Doha to the sewage network.
As a result, it will reduce the environmental impacts through the full control of odours in sewage treatment works and conveying system, and reduce other environmental problems arising from sewage overflow due to excess hydraulic pressure on the existing drainage network, where sewage flows exceed its capacity.
The main trunk sewer will be excavated using two Tunnel-Boring Machines designed specifically for the geological features encountered in Doha. To minimise the footprint within the city of Doha, five shafts will be excavated using a Vertical Shaft Machine.
The project will be complete by the first quarter of 2019. The Doha South Sewage Infrastructure Project is the first project in the region to implement the 'CEEQUAL' an international evidence-based sustainability assessment, rating and awards scheme for civil engineering, infrastructure, landscaping and works in public spaces.
The Joint Venture 'Bouygues Travaux Publics' and UCC' is the project contractor and 'CH2M' is the project management consultant.
