Saudi Water Partnerships Company is pleased to announce the release of two Request for Proposal (RFPs) for the development of Hadda Independent Sewage Treatment Plant and Arana Independent Sewage Treatment Plant located in Makkah. The RFPs have been released to developers who were prequalified through the Pre-Qualification Program whose results were announced in November 2024.
Developing these two ISTP projects is aligned with Saudi Arabia’s Vision 2030 and the National Water Strategy 2030 to enhance infrastructure and improve services through expanding sewage treatment capacities and promoting the utilization of treated sewage. The development will be undertaken in partnership with the private sector (PPP) under the BOOT (Build, Own, Operate, and Transfer) model. This will be implemented through 25-year Sewage Treatment Agreements from the dates of commercial operation, targeted for 2028 for both projects.
The Arana ISTP will be developed with an initial capacity of 250,000 cubic meters per day, expandable to 500,000 cubic meters per day while Hadda ISTP will have an initial capacity of 100,000 cubic meters per day, expandable to 250,000 cubic meters per day. Both projects will enhance the wastewater treatment capacity serving Makkah city and Holy Sites. The projects also encompass treated sewage effluent (TSE) re-use systems, comprising a transmission pipeline and storage tanks to maximize treated sewage utilization, particularly for irrigation across the Kingdom.
