Question

what is rainwater harvesting? explain and draw a diagram

Answer 1

Rain water harvesting (RWH) is a technique of collection and storage ofrainwater into natural reservoirs or tanks, or the infiltration of surface water into subsurface aquifers (before it is lost as surface runoff). One method of rainwater harvesting is rooftop harvesting.

Answer 2

The gathering of rainfall from a surface that permits the rainwater to be stored and utilised at a later time is one definition of rainwater harvesting.

Explanation:

Rainwater is collected from an impermeable surface, such as a building's roof, and stored in a tank or cistern in a typical rainwater harvesting setup. Rainwater may be collected from a variety of surfaces. Parking lots, highways, driveways, and even land surfaces are examples of other surfaces (once surface runoff from the land surface begins). Rainwater may be collected and stored for a variety of applications, including landscape irrigation, indoor potable and nonpotable water, and stormwater management. Rainwater harvesting is very important when there is no other source of water available.
