Qatar General Electricity & Water Corporation (Kahramaa) has invited contractors to submit bids for the project to build water transmission pipelines for the proposed Facility D independent water and power project (IWPP) at Qatar Economic Zone (QEZ).

Contractors have until 19 December to submit prices for the project, which will involve design, supply and installation of water transmission pipelines and associated fibre optic cables. The pipelines will include 69.5 kilometres (km) of 1,600 mm diameter pipes, 35 metres of 1,400mm diameter pipes and 1.2km of 1,200mm pipelines. The work will also include branch connections from the QEZ plant.

The proposed Facility D IWPP will have a power generation capacity of 2,400MW and a desalination component of 130 million gallons a day. Kahramaa is currently preparing to issue the request for proposal (RFP) for the IWPP, and is scheduled to award the contract next year. It will be the first new IWPP in Qatar since 2008.

Kahramaa’s last major desalination project project was the $500m Ras Abu Fontas A2 plant, which is being developed by the local Qatar Electricity & Water Company (QEWC).

QEWC is developing a 72 million gallons-a-day (g/d) multi-stage flash desalination plant next to the Ras Abu Fontas A1 plant. The UK’s HSBC is the financial adviser on the scheme. Japan’s Mitsubishi Corporation and Toyo Thai Engineering Company have been appointed to build the facility.
