Description
The Great Man-Made River, begun in 1984, is a roughly $25bn network pumping fossil water from the Nubian Sandstone Aquifer across hundreds of kilometres of desert to coastal cities. Before 2011 about 70% of Libyans depended on it. A NATO strike destroyed the Brega pipe factory that manufactured replacement pipe sections, triggering a maintenance collapse compounded by a decade of underinvestment, equipment looting, and power blackouts. Tripoli and Benghazi now suffer recurring multi-hour water cuts. The engineering functioned; the system failed because a non-renewing aquifer source combined with a single national distribution artery and a fragile state left no redundancy of any kind.

Lessons learned
- A single strike on one facility (the Brega pipe factory) crippled the entire maintenance supply chain for a national water lifeline — any replicator must plan geographically distributed spare-parts manufacturing and stockpiling.
- Fossil-aquifer dependency deepens over time as the stock drains and cannot recharge, making exit or diversification progressively harder and more expensive.
- Megaproject resilience is ultimately bounded by the institutional and security resilience of the state that must operate, maintain, and defend it for decades — engineering success cannot substitute for that.
