Saudi Arabia’s Water & Electricity (WEC) has invited companies to submit prequalification documents for a planned independent sewage treatment plant (ISTP) at Dammam.

Developers have until 18 January to submit prequalification documents for the planned ISTP, which will have a capacity of 330,000 cubic metres a day (cm/d). MEED reported in November that WEC had invited companies to submit expressions of interest for the Dammam scheme, which will be developed under a public-private partnership (PPP) model.

The project will be developed under a 25-year sewage treatment agreement (STA), under which the sewage capacity will be provided by the National Water Company (NWC). WEC’s obligations under the STA will be guaranteed by a credit support agreement from the Saudi government.

WEC is also planning to develop the planned Jeddah 2 Airport sewage treatment plant (STP) under a PPP model, which will have a total treatment capacity of 500,000 cm/d. The new ITSP will be located adjacent to the existing 350,000 cm/d Jeddah Airport STP.

The advisory team working on the Dammam and Jeddah Airport 2 ISTP projects will be led by Japan’s Mizuho Bank, financial adviser, and will also include UK-based Atkins, owned by Canada’s SNC Lavalin, technical adviser, and US-based law firm White & Case as legal adviser. MEED reported in September that the advisory team had been selected for a handful of planned PPP sewage treatment plants and related projects.
