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
Rainwater harvesting (RWH) is the process of collecting and storing rainwater rather than letting it run off. Rainwater harvesting systems are increasingly becoming an integral part of the sustainable rainwater management "toolkit" [5] and are widely used in homes, home-scale projects, schools and hospitals for a variety of purposes including watering gardens, livestock, [6] irrigation, home ...
The American Rainwater Catchment Systems Association (commonly referred to as ARCSA) is an American non-profit association founded by Dr. Hari Krishna in 1994, [1] focused on rainwater awareness and to promote sustainable rainwater harvesting (RWH) practices in the United States and around the world.
A rainwater catchment or collection (also known as "rainwater harvesting") system can yield 1,000 litres (260 US gal) of water from 1 cm (0.4 in) of rain on a 100 m 2 (1,100 sq ft) roof. Rainwater tanks are installed to make use of rain water for later use, reduce mains water use for economic or environmental reasons, and aid self-sufficiency.
These structures allow water to seep into the soil, retaining in the subsoil a greater amount of moisture. But also, it prevents the loss of fertile soil. [5] Semi-circular bunds are used to reforest arid zones with irregular rain patterns, allowing the growth of plants and trees, such as in the Sahel. [6]
A hand-drawn picture of a rainwater harvesting system in which potable water production (trough filtering) is imbedded. It is based on a drawing from the book "Duurzaam en Gezond Bouwen en Wonen" by Hugo Vanderstadt.

The purpose of rainwater harvesting in the Sahel and other dryland eco-agricultural regions is to extend the usability of irregular water inputs. [25] Banking rainwater (through techniques often summarized by the epigram " slow it, spread it, sink it ") is possible with site-appropriate techniques and as more water becomes "available for ...
Groundwater recharge also encompasses water moving away from the water table farther into the saturated zone. [1] Recharge occurs both naturally (through the water cycle) and through anthropogenic processes (i.e., "artificial groundwater recharge"), where rainwater and/or reclaimed water is routed to the subsurface.
