The Great Man-Made River (Arabic: النهر الصناعي العظيم, tr.: al-Nehr al-Ṣnā'ī al-'Ẓīm) of Libya is a network of pipelines built during the rule of Muammar Gaddafi that supply water to the Libyan Sahara desert from fossil aquifers, primarily the Nubian sandstone aquifer system. irrigation of the world.

It consists of more than 1,300 wells, most of them more than 500 meters deep, and provides 6,500,000 m³ (6.5 hm³) of fresh water per day to the cities of Tripoli, Benghazi, Sirte and other cities. The total cost of the project is estimated at more than 25 billion US dollars.

History

In 1953, efforts to find oil in southern Libya led to the discovery of vast amounts of water underground. The Grand Artificial River Project (PGRA) was conceived in the late 1960s and work on the project began in 1984. Management of the project fell to the body "Artificial River Project Authority" and was fully funded by the Libyan government with a budget of US$25 billion without having to resort to foreign funding. The main contractor for the first phases was Dong Ah Consortium and the current main contractor is Al Nahr Company Ltd. Since 1995 UNESCO has been involved in training the engineers and technicians involved in the project.

The technical material was manufactured in Korea and arrived by sea at the Libyan port of Brega in the Gulf of Sidra. The galvanic corrosion protection on the pipeline was supplied by an Australian company, AMAC Corrosion Protection, based in Melbourne and delivered via the port of Benghazi. The rest of the products were made in Libya.

The General People's Congress approved on October 3, 1983, the extraordinary session, to finance and execute the Great Artificial River Project. On August 28, 1984, the then President of Libya Muammar Gaddafi laid the first stone in the Sarir area, officially starting the works of the Great Artificial River Project. Two years later, on August 28, 1986, Gaddafi inaugurated the Brega prestressed concrete pipe factory. The pipes manufactured by this plant were considered the largest pipes made with this technology in the world. The steel wire was supplied by the Italian company Redaelli Tecna SpA with headquarters in Cologno Monzese (Milan). At the same time the similar manufacturing plant in Sarir was also inaugurated.

The first phase of the five in which the project was divided, was inaugurated on August 28, 1991, for its realization 85 million m³ of earth were excavated. The second phase was dubbed "First Water for Tripoli". Construction began on August 26, 1989 and was inaugurated on September 1, 1996.

Some of the milestones of the work are:

• 11 September 1989: Ajdabiya deposit is in service.
• 28 September 1989: Grand Omar Muktar ' s deposit is in service.
• 4 September 1991: the deposit of Ghardabiya enters service.
• August 28, 1996: water reaches Tripoli.
• September 28, 2007: water reaches Gharyan.
