Bahrain’s Public Works Ministry is expected to issue a request for qualification by the end of July to upgrade or extend the Tubli wastewater treatment plant according to sources close to the project.

The original proposal was to launch the tender process in June, but this date was expected to slip considerably as the ministry intended to award a contract for another wastewater treatment facility, at Muharraq. A total of five bids were submitted last week to build the Muharraq project.

However, sources close to the project have indicated that while a bidder has not yet been selected for Muharraq, the ministry is preparing the prequalification documents for Tubli already.

The Tubli plant currently treats effluent from about 600,000 people and is far exceeding its 200,000 cubic-metre-a-day (cm/d) design capacity, with flows peaking at 322,000 cm/d.

The structure of the Tubli deal is expected to follow that of the Muharraq deal. This means firms prequalified for Muharraq automatically prequalified for the Tubli tender.

The Public Works Ministry has mandated the UK’s HSBC as financial consultant, Germany’s Fichtner as technical adviser and the UK’s Norton Rose as legal adviser for both projects.
