Qatar's public works authority Ashghal has begun work on the QR920-million ($251 million) Mesaimeer Pump Station and Outfall Tunnel project, aimed at providing a sustainable solution to discharge surface and storm water.

It is the second phase of the Mesaimeer Surface and Ground Water Drainage Tunnel Project, which will provide a sustainable solution for the discharge of surface and storm water, said a statement from Ashghal.

The project is being implemented by a joint venture between Hamad Bin Khalid Contracting Company and Porr Qatar Construction Company, while the project management services is being handled by Mott MacDonald.

A leading engineering, management and development consultancy, Mott MacDonald is overseeing the design, implementation and operation of the project.

The scope of work includes construction of a pumping station at the end of Mesaimeer Tunnel, south of Hamad International Airport, besides 10 pumps and auxiliary facilities. The project also includes the construction of a 10-km-long tunnel with a 3.7 m diameter.

Dr Saad bin Ahmad Al Muhannadi, the president of Ashghal, said on completion, it will pump water from Mesaimeer Tunnel to the new outfall tunnel operating at a capacity of 19.7 cu m per second.

The project is designed to ensure the preservation of the marine environment, as the water, which will be pumped complies with the environmental assessment standards, and it is discharged 10 km off-shore to reduce the effect on the marine environment, stated Dr Al Muhannadi.

The project is scheduled to be completed in the fourth quarter of 2021, with a maintenance and operation period of three years, he added.-TradeArabia News Service
