An additional strategy to water conservation is practicing sustainable methods of utilizing groundwater resources. [8] Groundwater flows due to gravity and eventually discharges into streams. [ 9 ] Excess pumping of groundwater leads to a decrease in groundwater levels and if continued it can exhaust the resource. [ 8 ]
Italian oil drillers discovered Libya's underground water resources during the Italian colonization of Libya. This water lay dormant until 1969, when Muammar al-Gaddafi and American Armand Hammer built the Great Man-Made River to deliver the Saharan water to the coast. The water largely contributed to irrigation but cost four to ten times more ...
Water resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water. These resources can be either freshwater from natural sources, or water produced artificially from other sources, such as from reclaimed water or desalinated water (). 97% of the water on Earth is salt water and only three percent is fresh ...
Metering of water supply is usually motivated by one or several of four objectives. First, it provides an incentive to conserve water which protects water resources (environmental objective). Second, it can postpone costly system expansion and saves energy and chemical costs (economic objective).
A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions.
configuration of domestic rainwater harvesting system in Uganda. [1]Rainwater harvesting (RWH) is the collection and storage of rain, rather than allowing it to run off.. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit (well, shaft, or borehole), aquifer, or a reservoir with percolation, so that it seeps down and restores the ground w
Nadi (small johad) in Laporiya village of Rajasthan . Johad at Rithal village of Rohtak district of Haryana. A johad, also known as a pokhar or a percolation pond, is a community-owned traditional harvested rainwater storage wetland principally used for effectively harnessing water resources in the states of Haryana, Rajasthan, Punjab, and western Uttar Pradesh of North India, that collects ...
The water stored saves people from the daily task of walking long distances to fetch water from sources which are often contaminated. The water in a taanka is usually only used for drinking. If any year there was less than normal rainfall and household tanka do not get filled, water would instead be obtained from nearby wells and tanks to fill ...
