SHORT INFORMATION

Water source of Saudi Arabia

Until the 1980s, Saudi Arabia had lakes at Layla Aflaj and deep waterholes at Al-Kharj, fed by huge underground aquifers, formed in prehistoric times and non-renewable. Al Kharj was a valuable source of drinking water in an barren terrain. In recent years, these aquifer have been drawn upon heavily, both for agricultural and domestic purposes, and no fresh water remain in the lakes or pits.
