Stormwater harvesting or stormwater reuse is the collection, accumulation, treatment or purification, and storage of stormwater for its eventual reuse. While rainwater harvesting collects precipitation primarily from rooftops, stormwater harvesting deals with collection of runoff from creeks, gullies, ephemeral streams and underground conveyance.
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] These techniques are particularly beneficial in areas where rainfall is scarce and irregular, namely arid and semi-arid
Stormwater is also an important resource as human population and demand for water grow, particularly in arid and drought-prone climates. Stormwater harvesting techniques and purification could potentially make some urban environments self-sustaining in terms of water.
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
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 constructed swale or bioswale built in a residential area to manage stormwater runoff. A swale is a shady spot, or a sunken or marshy place. [1] In US usage in particular, it is a shallow channel with gently sloping sides. Such a swale may be either natural or human-made.
As the storm water runoff flows through the bioswale, the pollutants are captured and settled by the leaves and stems of the plants. The pollutants then enter the soil where they decompose or can be broken down by bacteria in healthy soil. [4] There are several classes of water pollutants that may be collected or arrested with bioswales.
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 ...
