Egis, an international  group offering engineering, project structuring and operations services, said it has won a major engineering, procurement and construction management (EPCM) contract to rehabilitate the Al Karaana lagoon in Doha, Qatar.

Located in the Al Rayyan region, the lagoon, which covers more than four sq km area, is raising serious environmental problems.

Almost 60,000 cu m of untreated wastewater is discharged onto this site per day by tanker, most notably causing the contamination of the water table by infiltration, producing foul odours and creating safety risks connected with the transport of sewage, said the Public Works Authority of Qatar (Ashgal) which awarded the contract.

Ashgal pointed out that it was working towards the eradication of the lagoon and the site’s comprehensive overhaul, in continuance of the measures taken to date to mitigate its environmental impact.

As per the contract, Egis will carry out the design of the wastewater treatment and the soil and water table decontamination, write the tender documentation, perform the design review of the plans and documents submitted by the selected contractor, and finally supervise the works.

The teams from Egis will be tasked with identifying and qualifying the lagoon’s waters and sludge in order to appreciate the contamination of the water table and evacuate this waste to the appropriate treatment processes, said a statement from the company.

Egis will consequently be mobilising all of its engineering capabilities for a period of 23 months to reduce to a minimum the environmental impact of this site, then redevelop it and convert it for new uses, in accordance with its sustainable development commitments, it stated.

The new Ashgal contract comes close on the heels of the Egis winning the extension of the Doha West waste water treatment and recycling plant deal this year, the statement added.-TradeArabia News Service
