NSAS Project Document

The Nubian Sandstone Aquifer System (NSAS) is one of the largest aquifers in the world covering approximately two million square kilometres of Northeast Africa in Chad, Egypt, Libya, and Sudan. The NSAS is the world’s largest fossil aquifer system with its reserves estimated at 375,000 km3. In the arid desert areas of those countries that share the aquifer, groundwater is a primary source of water for human populations and the indigenous ecosystems.
