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 ...
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.
Rain garden in Calgary, Alberta harvesting rainwater from roof The basic principle of LID to use nature as a model and manage rainfall at the source is accomplished through sequenced implementation of runoff prevention strategies, runoff mitigation strategies, and finally, treatment controls to remove pollutants.
To estimate the drainage requirement, the use of a hydrogeological water balance and a groundwater model (e.g. SahysMod [8]) may be instrumental. The water balance can be illustrated using a water balance graph which plots levels of precipitation and evapotranspiration often on a monthly scale.
Planting pits, Niouma [] near Yako, Passoré Province, Burkina Faso Rainwater harvesting in the Sahel is a combination of "indigenous and innovative" [1] agricultural strategies that "plant the rain" and reduce evaporation, so that crops have access to soil moisture for the longest possible period of time.
A semi-circular bund (also known as a demi-lune or half-moon) is a rainwater harvesting technique consisting in digging semi-lunar holes in the ground with the opening perpendicular to the flow of water. [1] [2]
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.
