A consortium led by Metito Utilities, a global investor, developer, and operator of sustainable water management solutions, co-led by Etihad Water and Electricity (EtihadWE), and SkyBridge Limited Company (SkyBridge), has been awarded the development of the Hadda Independent Sewage Treatment Plant (ISTP) project in the Makkah Province by the Saudi Water Partnership Company (SWPC), the Kingdom’s principal off-taker for water and wastewater PPP projects.
The project will play a critical role in strengthening wastewater infrastructure for one of the Kingdom’s most significant cities, Makkah, supporting both growing resident population and the millions of pilgrims visiting annually. The development aligns with the National Water Strategy 2030, launched under Saudi Vision 2030 which introduced a unified framework to enhance sector governance, improve efficiency, and accelerate private-sector participation across the water value chain.
As outlined under the National Water Strategy, Saudi Arabia is targeting the treatment of up to 10 million m3/day of wastewater and the reuse of 70% of treated effluent by 2030, advancing a fully circular and resilient water economy. The Hadda ISTP directly supports these national objectives by expanding wastewater treatment capacity and enabling large-scale water reuse in the Makkah Province.
Developed under a 25-year Build–Own–Operate–Transfer (BOOT) model, the project will have an initial treatment capacity of 100,000 m³/day, expandable to 250,000 m³/day to meet the growing demand. The consortium’s scope consists of the design, financing, construction, and operation of the wastewater treatment plant and its associated facilities under a public-private partnership model. It also includes a comprehensive treated sewage effluent (TSE) reuse system, comprising of a large storage tank and a 38-kilometre transmission pipeline with a throughput capacity of 350,000 m³/day.
The Hadda ISTP is designed to enhance wastewater treatment capacity for one of Saudi Arabia’s most strategically important cities. Its integrated reuse system will help optimize water resources, support irrigation needs, and improve environmental outcomes. Treated effluent will be supplied to the Saudi Irrigation Organization (SIO). Commercial operations are scheduled to commence in Q4 2028.
