• Water transmission pipeline will link desalination plant in Ras Laffan to two of the mega reservoir sites
  • Pipeline will have total length of 28.5 kilometres
  • Companies have until 3 September to submit bids for contract

Qatar General Electricity & Water Corporation (Kahramaa) has invited companies to submit bids for the contract to provide and install a major transmission pipeline to link a desalination plant in Ras Laffan Industrial City and reservoirs at the Water Security Mega Reservoirs project.

The contract will involve designing and installing the complete piping system from the Facility E desalination plant in Ras Laffan Industrial City and the primary reservoir and pumping station (PRPS) 1, near Umm Birka, and the PRPS 2 at Umm Slal.  

The selected firm will be required to provide a hydraulic study and surge analysis study before beginning to construct the pipeline. The pipeline will have a circumference of 1,600 millimetres, and cover a total length of 28.5 kilometres.

Companies have until 3 September to submit bids for the deal.

The $3bn Water Security Mega Reservoirs scheme has been designed to provide seven days of strategic water storage within its network, which will shore up the country’s reserve water supplies to protect against any future disruptions.

Each reservoir site will contain up to 10 reservoir modules, which could be the largest of their type in the world. The reservoirs and pipeline network, with associated pumping stations, are planned to store up to 15 million cubic metres of potable water. The scheme is set for completion in 2019.

The project will connect the desalination plants at Ras Laffan and Ras Abu Fontas, which will skirt the west side of Doha. The pipeline will also connect to five reservoirs on the outskirts of the capital, which will be linked by about 200km of large-diameter pipeline.

MEED reported in May that Kahramaa had selected four firms for the five main construction packages on the reservoirs scheme.

Contracts for the 200km of pipeline connecting the reservoirs to desalination plants and supply networks have been awarded to the UAE’s Habtoor Leighton Group, local firm AlJaber Engineering, Chinese firms China Harbour Engineering and Sinohydro Group, and a joint venture of Lebanon’s CAT and the local Boom Construction.
