Qatar invites bids for water injection scheme

03 September 2013

Contract will involve design and build of water injection scheme at 10 sites

Qatar’s Public Works Authority (Ashghal) has invited companies to submit bids for the contract to build a deep injection system for the disposal of groundwater and surplus treated sewage effluent (TSE).

Contractors have until 24 September to submit bids for the tender.

The system is planned to be used for the areas of Doha, Wakrah and Khor and to consist of one or more deep injection wells, at each site, two monitoring wells and water sampling and analysis facilities. The system is also planned to be introduced in 10 separate areas. The duration of the contract will be about five years.

The project is the latest of a number of schemes that Doha is pressing ahead with to improve the country’s wastewater and drainage infrastructure. In August, Ashghal announced it is planning to build a $474m wastewater project in northern Doha. The scheme will include the design and construction of a wastewater pumping station, an associated pipeline network and a lifting station.

Ashghal has just completed work on the $190m second phase of its Doha South water treatment plant. The expansion will increase the capacity of the facility by 92,000 cubic metres a day (cm/d) to 200,000 cm/d.
