Qatar’s Public Works Authority (Ashghal) is evaluating five technical bids for the $150m contract to expand its Doha South wastewater treatment plant.

Bidders say they expect Ashghal to shortlist technically qualified contractors before it opens their commercial bids.

The state-run utility plans to award the contract for the second phase of the project to expand Doha South by early 2010.

Five contractors bid for the engineering, procurement and construction contract in July.

They were France’s Veolia; South Korea’s Daewoo Engineering & Construction; a team of India’s Larsen & Toubro and the US’ ITT Corporation; Singapore’s Keppel Seghers; and Austria’s VA Tech Wabag.

The UK’s Hyder Consulting is the adviser on the scheme.

The scheme will add 80,000 cubic metres a day of treatment capacity at the Doha South site.

The extra treatment capacity will enable the plant to treat wastewater from an additional 295,000 people.  

In February 2004, Qatar’s Teyseer Contracting Company won a $41.5m engineering, procurement, installation and commissioning contract to add 70,000 cubic metres a day (cm/d) of new treatment capacity to the Doha South plant. ITT Corporation was responsible for the design, supply and supervision of the development of a sewerage system at the plant.

The second phase of the project to expand the plant will take the site’s total capacity to 192,000 cm/d.

In late May, Ashghal awarded a €44m ($61m) operation and maintenance contract for the existing 112,000 cm/d Doha South wastewater treatment plant to Veolia. Under the seven-year contract, Veolia will also maintain a 12,000 cm/d industrial area plant.

Veolia has the option of extending the contract for a further three years.
