Qatar’s Public Works Authority (Ashghal) has extended the submission date for prequalification entries for a planned public-private partnership (PPP) sewage treatment plant (STP) to service the Wakra and Al-Wukair areas of Doha.

The prequalification deadline was extended to 28 May from 14 May.

MEED reported earlier in April that developers had been invited to submit expressions of interest (EOIs) by 7 April for the planned sewage plant, which will have a treatment capacity of 150,000 cubic metres a day (cm/d).

The client is aiming to launch the request for proposals (RFP) in July and select a preferred bidder in December. The plant is scheduled to enter commercial operation in February 2023.

The successful bidder will sign a public-private partnership agreement (PPPA) with Ashghal to cover the development of the STP on a build, operate and transfer (BOT) model. The PPPA will be for a period of 25 years, with Ashghal’s payment obligations backed by a sovereign guarantee.

The client has appointed a team of advisers led by UK-based PwC, with the UK’s Mott MacDonald as technical adviser and UK law firm Eversheds Sutherland as the legal adviser.
