a short note on rain water harvesting
Answers
Answer:
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. Dew and fog can also be collected with nets or other tools. Rainwater harvesting differs from stormwater harvesting as the runoff is collected from roofs, rather than creeks, drains, roads, or any other land surfaces.[1][2] Its uses include watering gardens, livestock,[3] irrigation, domestic use with proper treatment, and domestic heating.
Answer:
Rainwater harvesting is a technique that is used for collection and storage of rainwater into natural reservoirs or tanks or the infiltration of surface water into subsurface aquifers before it is lost by running off. The most common method of rainwater harvesting is rooftop harvesting.
