The Great Man Made River Project, which, since it's conception in 1984 has grown to include almost 4,000 km (2,485 miles) of mainly 4 meter diameter pre stressed concrete cylinder pipe (PCCP). Eventually over 6.0 million m3 (5260 acre-feet) of water will be conveyed every day from well fields deep in the Sahara desert to the population centers that are concentrated on the northern coastal strip.
