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
This technique of harvesting rainwater was perfected to a fine art in the arid regions of western Rajasthan. Such water harvesting structures have also been reported being built in other arid developing countries such as Botswana, Ghana, Kenya, Yemen, Sri Lanka, Thailand, and Indonesia. [6] Bikaner was founded by Rao Bika in 1488 AD. The choice ...
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 ...

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.

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 ...
Stormwater harvesting deals with the collection of runoff from creeks, gullies, ephemeral streams, and other ground conveyances. Stormwater harvesting projects often have multiple objectives, such as reducing contaminated runoff to sensitive waters, promoting groundwater recharge, and non-potable applications such as toilet flushing and irrigation.
Research on Kenyan dams shows that only 1 to 3% of rainwater is retained behind any individual dam, the remainder continues its natural flow towards the ocean. [1] Eventually the dams fill with sand - sometimes after only one rainfall or over 1 – 3 seasons. 25 to 40% of the volume of the sand held is actually water.
