Question

What is rainwater harvesting? What are the two ways in which it can be done?

Answer 1

Rainwater harvesting is storing the rainwater for future use. Rainwater harvesting can be done in the following two ways:

(i) The rainwater that falls on the roof of the buildings is directed towards a deep pit in the ground. In this way, the ground absorbs the water and thereby adds to the underground water reserves.

(ii) Instead of allowing the rainwater to flow into the drains, the rainwater has to be directed to the underground pits to again boost groundwater levels.
