The population of Egypt has more than tripled over a half century, from 22 million in 1952 to over 73 million today. At the same time, the cultivated land area has grown moderately from 2.23 to 3.28 million hectares. In 1997 the Egyptian Ministry of Public Works and Water Resources launched a 20-year master plan to address the future of land and water development in Egypt. The plan called for reclamation and irrigation of 138 million hectares of additional land, and for a supply of 23 - 24 million cubic meters of water for irrigation and other needs. As a major part of the plan, the South Valley Project was established to reclaim and irrigate at least 400,000 hectares through the use of an irrigation canal system that could distribute surface water from Lake Nasser across the Western Desert. The main feeding irrigation canal is an open-earth canal with trapezoidal cross section, roughly 30 m wide at the bottom, 8 m deep, with 2:1 (horizontal:vertical) side slopes. The total length of the main carrier and main branch canals is about 240 km. The key component of the canal lining system is an impermeable geomembrane to prevent water loss. The profile of the canal lining system consists of a soil-cement stabilized subgrade, a 1.5 mm textured high-density polyethylene (HDPE) geomembrane, 10 cm of a soil-cement mixture, and 20 cm of fibre-reinforced concrete. Poly-Flex Inc. (USA) has produced approximately 1,300,000 m2 of the custom geomembrane product for this project. At a total estimated cost of USD 992 million, the South Valley Project and its affiliated developments will be a great step forward in developing 600,000 km2 of land in the Western Desert.
