Qatar’s General Electricity and Water Corporation (Kahramaa) has issued a tender inviting local and international firms to bid to build five huge new reservoirs and associated pumping station packages.

The reservoirs will be among the biggest of their type in the world, with nine reservoir modules in each one - five of which are being included in the current tender documents.

They will be based at Umm Birka, Umm Slal, Al Thumama, Rawdhat Rashid and Abu Nakhla.

The five separate contract packages cover the material supply, construction, testing and commissioning of the reservoirs, including pipework, mechanical, electrical, ICA (instrumentation, control and automation), civil, structural and architectural works.

The pumping stations will link from the Ras Abu Fontas and Facility D desalination plants to the south of Doha to the Ras Laffan desalination plants in the north of Qatar. A 200km-long network of large diameter ring mains will link the individual sites.

Contractors looking to bid to build the plant need to submit their proposals by 5 June.

The objective of the project is to provide seven days’ potable water storage in new reservoirs, combined with existing and future secondary reservoirs, to preserve Qatar’s water security. They will be capable of storing 17mn m3 of water.

Kahramaa has developed the project alongside design and site supervision consultant Hyder.

A fast-track design, procurement and construction sequence has been undertaken to allo for the project to be delivered as quickly as possble. The project is scheduled to complete in 2017.

Hyder's managing director for utilities, Kamiran Ibrahim, said: “Hyder is proud to have contributed to the successful progress of this strategically important project for the state of Qatar and its people.

"It is also hugely significant for the utilities sector in the region and globally. As the largest ever water security undertaking, it is sure to have an impact around the world where other countries are seeking to ensure strategic water supplies for their populations.”
