The Kingdom is now the world's largest producer of desalinated water. The 27 desalination plants provide drinking water to major urban and industrial centers through a network of water pipes running for more than 2,300 miles. Desalination meets 70% of the Kingdom's drinking water requirement. Several new desalination plants are under construction. Once completed, the Kingdom's network of desalination plants will have a capacity of 800 million gallons a day.
