The submitted proposals will now be comprehensively evaluated to determine the winning consortium. Following the announcement of preferred bidders, agreements will be signed and development of the project is expected to commence next year, with commercial operations targeted for 2030.
The initial design capacity of the Riyadh East ISTP is 200,000 cubic meters per day, expandable to 400,000 cubic meters per day. The project also includes the development of treated sewage effluent (TSE) reuse systems, including transmission pipeline, aimed at maximizing water reuse in various applications, particularly agricultural irrigation across the Kingdom.
This milestone follows the issuance of the Request for Proposal (RFP) documents in October 2025, as part of SHARAKAT’s commitment to develop water infrastructure through Public-Private Partnership (PPP) based on the Build-Own Operate-Transfer (BOOT) model for a duration of 25 years.
SHARAKAT affirms its continued commitment to attracting local and international investment, and to enhancing partnership opportunities with the private sector in the development of critical infrastructure projects and to improve services. These
efforts are aligned with the objectives of the National Water Strategy and the National Privatization Strategy, particularly in enabling greater private-sector participation in the development and operation of infrastructure projects, while supporting the objectives of Saudi Vision 2030.
