Great Man Made River Project

🏗️ Phase IV & V Objectives and Achievements (2000–2011)

âś… Key Enhancements Completed or Near Completion


NATO Bombings and Infrastructure Damage (2011)

In 2011, during the NATO-led military intervention in Libya, critical parts of the GMMR system were bombed, including civilian infrastructure—prompting international concern.

❌ Confirmed Destruction

Note: NATO claimed the bombings were aimed at military targets, alleging the use of the factory for military purposes—claims not substantiated by independent observers.


đź”§ Current Status (as of 2025)

Despite extensive damage during the war and political instability since:


đź§ľ Conclusion

Phases IV and V of the GMMR were Libya's most advanced attempt to modernize and complete the dream of water independence. The destruction of critical infrastructure during the NATO intervention in 2011—particularly the Brega Pipe Factory—crippled Libya’s ability to finish or maintain this monumental project.

As of 2025, the GMMR still supplies millions with water, a testament to the original engineering and ambition behind it, but it operates at reduced capacity, with significant long-term vulnerabilities.


Great Man Made River Project 1984 - 2011

📊 Facts & Figures, Page Links

  • Project Name: Great Man-Made River (GMMR)

  • Initiated by: Muammar Al Gaddafi

  • Start Date: Officially launched in 1984


🛠️ Timeline of Construction Phases

📍 Phase I (1984–1991)

  • Scope: Transfer of water from As-Sarir and Tazerbo wells to Benghazi and Sirte

  • Infrastructure: 1,600 km of pipeline

  • Storage: Construction of large reservoirs like Omar Mukhtar Reservoir

📍 Phase II (1991–1996)

  • Scope: Supply of water from Fezzan (southern Libya) to the Western coastal belt including Tripoli

  • Pipelines: Roughly 1,300 km

  • Built to serve: Capital Tripoli and surrounding areas

📍 Phase III (1997–2000s)

  • Goal: Link the eastern and western systems and expand connections to more towns

  • Integration: Unified water grid across major urban and agricultural zones

📍 Phase IV and V (2000s–2011)

  • Enhancements: Construction of additional pipelines, pumping stations, and reservoirs

  • Status: Partially completed due to NATO bombing in 2011, which damaged GMMR facilities and halted work

Objectives of the River Project

In the ninth month of the year (1984) began work on a Great Man Made River to transport groundwater basins infidels and bed and Tazrbu and Fezzan in the south to the cities of Benghazi and Sirte and Tripoli, Tobruk and other coastal cities in the north through the system, huge pipes huge total extension of about (3.380 ) kilometers was set up two plants in the bed and Brega for the provision of these tubes made of material concrete the previous stress and is buried in the trenches of the underground at a depth of (7) meters have been drilled (960) wells at depths ranging from (450) meters, and between (650) meters in the basin Tazrbu bed and Fezzan and Kufra.

1. Stop the growing clouds of limited groundwater reserves in the coastal cities and stop saline intrusion from the sea to drinking water and agricultural land.
2. Farming close to (180) thousand hectares, achieving self-sufficiency of a mass of food products where the strategy will be allocated more than (80%) of river water for agriculture.
3. The creation of light industries and other medium-heavy and a third advantage of the abundance of water and add to the GDP
4. Stop the migration from the countryside to the cities and fight against desertification and solve obsessed with food security and the creation of the mass people economically and developmentally for the post-oil.


Facts and Figures

1. Experts estimate that the amount of fresh water that will flow through the pipeline to ensure sufficient reserves, the mass of water to more than (50) years on the basis of six million cubic meters of supplies a day.
2. According to studies, the size of the underground stock of Kufra Basin over the volume of water flowing from the Nile Basin over the (220) years.
3. Equal to the volume of water that flow daily half the size of the oil that is produced each day from oil fields in the world.
4. The capacity of the bed and Brega manufacturers for the production of pipe (220) tube in the day, equivalent to five times greater production plant in the world.
5. The length of wire wrapped around the (250) A tube which form the body of the river in the first stage enough to wrap around the globe (230) times.
6. Upon completion of stages of the river which entered the material in its implementation as follows: -

  • · (547.000) tube
  • · (5.200.000 tons) of cement
  • · (24,000,000) tons of rubble and gravel
  • · (4.300.000) kilometers of steel wire
  • · (43.000.000) kilometers from sheets of iron and steel
  • · (155.000.000) cubic meters of soil excavation.

The Great Man-Made River (GMMR) – Libya’s Forgotten Engineering Wonder

Often referred to as “the eighth wonder of the world,” the Great Man-Made River (GMMR) was one of Muammar Al Gaddafi’s most ambitious and visionary projects — a massive underground water system designed to bring fresh water from the Saharan desert aquifers to Libyan cities and farmlands.

This vast, self-funded infrastructure project transformed arid land into productive farmland and provided clean drinking water to millions, without foreign debt or Western control.

Though heavily damaged and forgotten after the 2011 NATO-backed war, its legacy stands as a powerful symbol of African self-reliance and visionary engineering.
