The project involves the detailed study and design of 2,403 km of water systems and 1,646.3 km of sewerage networks to connect villages and development centers across the Taif province and its corridors to Baha and Riyadh. It aims to enhance water delivery and sanitation coverage through the planning of transmission lines, tanks, treatment plants, and sewage systems up to 2050. The project also integrates environmental assessments, value engineering, renewable energy (solar), and infrastructure design to ensure sustainable urban expansion and efficient service delivery.
