The Public Works Authority ‘Ashghal’ started the construction works of the Mesaimeer Pump Station and Outfall Tunnel projects, which will provide a sustainable solution to discharge surface and storm water.

Dr. Eng. Saad bin Ahmad Al Muhannadi, President of the Public Works Authority ‘Ashghal’ inaugurated the project’s works in the presence of officials from the Drainage Networks Projects Department at the Public Works Authority, and representatives of the supervision consultants and contractor.

The total cost of the project is QAR 920 million and it includes the construction of pumping station with 10 pumps and auxiliary facilities. The pumping station will be located at the end of Mesaimeer Tunnel south of Hamad International Airport. The project also includes the construction of a 10 kilometer tunnel with a 3.7 meters diameter. The pumping station will operate at a capacity of 19.7 cubic meters per second, its function is to pump water from Mesaimeer Tunnel, which was completed in 2016, to the new outfall tunnel.

It is worth noting that 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 ten kilometers off-shore to reduce the effect on the marine environment. The project is scheduled to be complete in Q4 2021, with a maintenance and operation period of three years. The project is being implemented by the JV of Hamad Bin Khalid Contracting Company and PORR Qatar Construction Company. The project management services has been assigned to Mott Macdonald Ltd. who will oversee the design, implementation and operation of the project.

Mesaimeer Pump Station and Outfall Tunnel 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. Mesaimeer Tunnel was completed in late 2016 and it is one of the projects implemented by Ashghal in the development of drainage networks. In 2017, the project won the global best project award in the wastewater category, during the Engineering News Record (ENR) Global Best Projects Awards in New York City, in the presence of a group of the largest international companies executing global construction projects.

The tunnel extends below the G-Ring Road for 10 kilometers with a depth of about 30 meters below the ground surface. This main tunnel is linked to the existing and planned drainage networks in the areas that traverse through, and will collect and discharge surface water from approximately 170 km² of catchment area, as it is connected to rain water drainage networks in 22 vehicle tunnels.
