Great Man Made River Project
Welcome to the official page dedicated to one of the greatest civil engineering achievements of the modern era — The Great Man-Made River (GMMR).
Born from the vision of Muammar Al Gaddafi, the GMMR was designed to unlock Libya’s ancient underground water reserves and bring fresh, clean water from deep beneath the Sahara to the coastal cities, farmlands, and communities of Libya. This monumental project has been described by engineers, environmentalists, and world leaders alike as "the largest irrigation project in the world."
With over 1,600 wells, stretching more than 4,000 kilometers of buried pipelines, the GMMR became a symbol of self-reliance, sovereignty, and sustainable development — built without loans or Western corporate control.
This website explores the history, science, and legacy of this visionary project — a lifeline that still serves millions today, despite years of conflict and sabotage.
Great Man Made River Project 1984 - 2011
Project Name: Great Man-Made River (GMMR)
Initiated by: Muammar Al Gaddafi
Start Date: Officially launched in 1984
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
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
Goal: Link the eastern and western systems and expand connections to more towns
Integration: Unified water grid across major urban and agricultural zones
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
