The Great Man-Made River is the world's largest irrigation project. The project utilizes a pipeline system that pumps fossil water from the Nubian Sandstone Aquifer System from down south in Libya to cities in the populous Libyan northern Mediterranean coast including Tripoli and Benghazi. The water provides 70% of all freshwater used in Libya. During the second Libyan civil war, lasting from 2014 to 2020, the water infrastructure suffered neglect and occasional breakdowns.
