Question

it is rain water harvesting techniques

Answer 1

Hey friend......

Rain water harvesting (RWH) is a technique of collection and storage of rainwater 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. With rooftop harvesting, most any surface — tiles, metal sheets, plastics, but not grass or palm leaf — can be used to intercept the flow of rainwater and provide a household with high-quality drinking water and year-round storage. Other uses include water for gardens, livestock, and irrigation, etc.

The reasons for using rainwater harvesting systems answer three questions:

What: Rainwater harvesting will improve water supply, food production, and ultimately food security.

Who: Water insecure households or individuals in rural areas will benefit the most from rainwater harvesting systems.

How: Since rainwater harvesting leads to water supply which leads to food security, this will greatly contribute to income generation.


Hope this will help you.....

Answer 2

Rainwater harvesting is the process of collection of rainwater from surfaces on which rain falls, filtering it and storing it for multiple uses. Rainwater harvesting puts the supply of water back to normal levels. It is the collection and storage of water from surfaces that rain has fallen upon.
