Located in the Al Rayyan region, west of Doha, the Al Karaana lagoon covers more than 4 sq.km and is raising serious environmental problems. Almost 60,000 cubic metres of untreated wastewater per day is discharged onto this site 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.
The Public Works Authority of Qatar, Ashgal, has just awarded Egis an engineering, procurement and construction management (EPCM) contract to rehabilitate this lagoon. Ashgal wishes for the eradication of the lagoon and the site’s comprehensive overhaul, in continuance of the measures taken to date to mitigate its environmental impact.
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.
They 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.
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.
This new contract gained follows another one awarded several weeks ago, also in the water sector: the extension of the Doha West waste water treatment and recycling plant.
The contract further bolsters Egis’ position in Qatar, where the Group generated almost 33 million euros of turnover in 2014 from its contributions to a large number of infrastructure projects.
Egis is an international group offering engineering, project structuring and operations services. In engineering and consulting, its sectors of activity include transport, urban development, building, industry, water, environment and energy. In roads and airports its offer is enlarged to encompass project structuring, equity investment, turnkey systems delivery, and operation and maintenance services. Employing 12,000 people, including 7,500 in engineering, the group generated a turnover of €881 million in 2013.
Egis is 75% owned by the French “Caisse des Dépôts” and 25% owned by Iosis Partenaires, (a “partner” executive and employee shareholding)
