YOU HAVE HEARD ABOUT RAIN WATER HARVESTING BUT ARE NOT VERY SURE WHAT IT IS FIRST THINK OF THE QUESTIONS YOU WOULD LIKE TO ASK AND THEN FRAME A LETTER TO THE WATER RESOURCES DEPARTMENT ASKING FOR INFORMAtion​

Answer 1

Answer:

For a dry period of four months, the required minimum storage capacity would be about 12,000 litres. As rainwater supply depends on the annual rainfall, roof surface and the runoff coefficient, the amount of rainwater that can be collected = rainfall (mm/year) x area (m2) x runoff coefficient.

Explanation:

Rain water harvesting 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.
