These projects aim at recycling purified sewage water for agricultural and industrial use. The first project was established in the city of Riyadh
and saves about 200,000 cubic meters of purified water per day, water which is transported through pipes to plantations in the regions of al-Dara'is and Dairab, Arga, Al Ammariya and Al Hayer for agricultural purposes. An additional 20,000 cubic meters of such treated water is used for industrial purposes. Similar projects are planned for the cities of al-Qasim and al-Dammam.
