Encyclopedic overview
Schematic drawing of the project. Note that different routes have been proposed for the not-yet-implemented phases (dashed). Tobruk may for instance end up connected to Ajdabiya instead of to the Jaghboub well field. 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. The water covers a distance of up to 1,600 kilometers and provides 70% of all fresh water used in Libya.
