Great Man-Made River

Pipes supplying water to northern Libya

The Great Man-Made River Project (Arabic: النهر الصناعي العظيم, romanized: an-nahr aṣ-ṣināʿiyy al-ʿaẓīm, abbreviated GMRP) is a network of pipes that supplies fresh water obtained from the Nubian Sandstone Aquifer System, a fossil aquifer, across Libya. It is the world's largest irrigation project. The project utilizes a pipeline system that pumps water from the Nubian Sandstone Aquifer System, in southern Libya, to cities along the populous northern Mediterranean coast of Libya, including Tripoli and Benghazi.
