Saudi Arabia is expected to begin the pre-qualification process for the contract to develop two independent sewage treatment plants early next year, MEED reported citing an industry source.
The new facilities will have a total combined capacity of 900,000 cubic meters a day, and will be added to the original three schemes: Al-Haer ISTP in Riyadh, Riyadh East ISTP, and Khamis Mushait ISTP.
Two smaller schemes, Riyadh East and Khamis Mushait, will be developed as one contract, MEED said.
The request for proposals for the contracts to develop all three schemes are expected to be issued by October, by the Saudi Water Partnership Co..
