Qatar’s General Electricity and Water Corporation (Kahramaa) has announced the tender for the construction of five primary reservoir and pumping station (PRPS) packages as part of its water security mega reservoirs project.

The five separate packages (A – E), cover material supply, construction, testing and commissioning related to the reservoirs, pumping stations, pipework, mechanical, electrical, ICA (instrumentation, control and automation), civil, structural and architectural works for the mega reservoir sites at Umm Birka, Umm Slal, Al Thumama, Rawdhat Rashid and Abu Nakhla.

Local and international contractors are required to submit their proposals by June 5, 2014.

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 quality in line with Kahramaa and World Health Organization (WHO) standards.

The project entails the construction of five mega-reservoir sites and approximately 200 km of large diameter ring mains.

Each reservoir site will ultimately include up to nine reservoir modules, with up to five per site being included in the current tender, each of which will be among the largest of their type in the world. The reservoirs and pipeline network, with associated pumping stations, will provide up to 17 million cubic meters of strategic potable water storage. A massive ring main system will be provided between the independent water and power generation plants, allowing water to flow from North to South and vice versa; so that it may be delivered to any location in Eastern Qatar, irrespective of water availability.

Hyder Consulting is the detail design and site supervision consultant on the project and has been working closely with Kahramaa since March 2012 to fast track the unique design of the mega reservoirs, pumping stations and pipework to meet the client’s ambitious programme.

This technically demanding undertaking involves complex hydraulics and operational philosophies, mixed with the engineering and stakeholder challenges associated with delivering such significant volumes of water storage and networkin, Hyder Consulting said. - TradeArabia News Service
