The Saudi Water Partnership Company is pleased to announce the release of two Requests for Proposals (RFPs) for the development of the Hadda Independent Sewage Treatment Plant and the Arana Independent Sewage Treatment Plant, located in Makkah city. 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 aligns with Saudi Arabia’s Vision 2030 and the National Water Strategy to enhance infrastructure and improve services by 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.
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, the 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.
