The Great Manmade River is a network of pipes that supplies 6,500,000 m³ of fresh water per day from beneath the Sahara Desert, from the Nubian Sandstone Aquifer System fossil aquifer, to the cities in the north of Libya, including Tripoli, Benghazi and Sirt. The project consists of more than 1,300 wells, most more than 500 m deep. According to the 2008 edition of Guinness Book of Records, it is the world's largest irrigation project.
The first phase of construction started in 1984, and cost about $5 billion. The completed project may total $25 billion.
Muammar al-Gaddafi has described it as the "Eighth Wonder of the World" and presented the project as a gift to the Third World.
