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 ...
Surface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to channel runoff (or stream flow).It occurs when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil.
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.
Rainwater harvesting; High-efficiency clothes washers; Weather-based irrigation controllers; Garden hose nozzles that shut off the water when it is not being used, instead of letting a hose run. Low flow taps in wash basins; Swimming pool covers that reduce evaporation and can warm pool water to reduce water, energy and chemical costs.
The term "first flush effect" refers to rapid changes in water quality (pollutant concentration or load) that occur after early season rains. Soil and vegetation particles wash into streams; sediments and other accumulated organic particles on the river bed are re-suspended, and dissolved substances from soil and shallow groundwater can be flushed into streams.
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 ...
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.
