Great Man-Made River(Redirected from Great Manmade River Project)
The Great Man-Made River (GMR, النهر الصناعي العظيم) is a network of pipes that supplies water to the Sahara in Libya, from the Nubian Sandstone Aquifer System fossil aquifer. It is the world's largest irrigation project.
According to its website, it is the largest underground network of pipes (2,820 kilometres (1,750 mi)) and aqueducts in the world. It consists of more than 1,300 wells, most more than 500 m deep, and supplies 6,500,000 m3 of fresh water per day to the cities of Tripoli, Benghazi, Sirte and elsewhere. It is also the world's largest irrigation project. The late Libyan Leader Muammar Gaddafi described it as the "Eighth Wonder of the World". But in 2011 it was damaged by NATO, due to which Libya is still facing water shortages.
In 1953, efforts to find oil in southern Libya led to the discovery of large quantities of fresh water underground. The Great Man-made River Project (GMRP) was conceived in the late 1960s and work on the project began in 1984. The project's construction was divided into five phases. The first phase required 85 million m³ of excavation and was inaugurated on 28 August 1991. The second phase (dubbed First water to Tripoli) was inaugurated on 1 September 1996.
The project is owned by the Great Man-Made River Project Authority and was funded by the Gaddafi government. The primary contractor for the first phases was Dong Ah Consortium and the present main contractor is Al Nahr Company Ltd.
The imported goods were made in Korea and destined to the construction of the GMR arrived by sea via the entry port of Brega (Gulf of Sidra). Cathodic corrosion protection on the pipeline was supplied by an Australian company, AMAC Corrosion Protection, based in Melbourne and delivered via Port of Benghazi. The rest of goods were made in Libya.
The total cost of the project is projected at more than US$25 billion. Libya has completed the work to date without the financial support of major countries or loans from world banks. Since 1990 UNESCO has provided training to engineers and technicians involved with the project.
The fossil aquifer from which this water is being supplied is the Nubian Sandstone Aquifer System. It accumulated during the last ice age and is not currently being replenished. If 2007 rates of retrieval are not increased, the water could last a thousand years. Independent estimates indicate that the aquifer could be depleted of water in as soon as 60 to 100 years. Analysts say that the costs of the $25 billion groundwater extraction system are 10% those of desalination.
On 22 July during the 2011 Libyan civil war, one of the two plants making pipes for the project, the Brega Plant, was hit by a NATO air strike. At a press conference on 26 July, NATO explained that rockets had been fired from within the plant area, and that military material, including multiple rocket launchers, was stored there according to intelligence findings, presenting a photo showing a BM-21 MRL as an example.
In this project 1,000 million euros were invested for the installation of 50,000 artificial palm trees for water condensation. This project was carried out by the Spanish engineer Antonio Ibáñez de Alba
- 3 October 1983: The General People's Congress held an extraordinary session to draft the resolutions of the basic people's Congresses, which decided to fund and execute the Great Man-Made River Project.
- 28 August 1984: Muammar Gaddafi laid the foundation stone in Sarir area for the commencement of the construction of the Great Man-Made River Project.
- 28 August 1986: Muammar Gaddafi inaugurated the Brega plant for the production of the pre-stressed concrete cylinder pipes, which are considered the largest pipes made with pre-stressed steel wire (the majority of steel wire was made in Italy by the Redaelli Tecna S.p.A. company with its head office in Cologno Monzese-Milan and its factory in Caivano-Naples). The Sarir plant was also inaugurated on this date.
- 26 August 1989: Muammar Gaddafi laid the foundation stone for phase two of the Great Man-Made River Project.
