The transport of pipe segments for the Great Man-Made River (GMMR) in the Sahara desert, Libya, during the 1980s.A network of pipes that supplies water from the Nubian Sandstone Aquifer System, a fossil aquifer in the Sahara desert of Libya, the GMMR is the world's largest irrigation project.
The water covers a distance of up to 1,600 kilometers and provides 70% of all freshwater used in Libya. [2] According to the project's website, it is the largest underground network of pipes (2,820 kilometres (1,750 mi)) [3] and aqueducts in the world.
The karez water system is made up of a network of interconnected wells. Karez gallery near Turpan, Xinjiang, China. Turpan's karez water system is made up of a horizontal series of vertically dug wells that are then linked by underground water canals to collect water from the watershed surface runoff from the base of the Tian Shan Mountains and the nearby Flaming Mountains.
The cork-screwing funnels are for access to the underground aqueduct. An aqueduct emerges from an underground or gallery puquios into a trench which supplies water for irrigation and domestic uses. Except for river valleys where irrigation is possible, the desert of the Nazca Region is barren. The Pan American Highway is in the distance.

Dairy farming in Mexico's main milk-producing region - the nearby city of Torreon - has since the beginning of the 20th century heavily relied on Cuatro Cienegas for water to feed wells used for ...
Other desert features include rock outcrops, exposed bedrock and clays once deposited by flowing water. Temporary lakes may form and salt pans may be left when waters evaporate. There may be underground water sources in the form of springs and seepages from aquifers. Where these are found, oases can occur.
The Arabian Aquifer System is primarily located in Saudi Arabia but also in Jordan, Syria, Iraq, Kuwait, Bahrain, Qatar, United Arab Emirates, Oman, and Yemen. [1]Starting in the 1980s, Saudi Arabia's rapid agricultural development fueled by government involvement and subsidies resulted in a large increase in water being drawn from the aquifers in the system, many of which are non-renewable.
