Question

What is rainwater harvesting? What is the need of rainwater harvesting? Mention any four rainwater harvesting structures.

Answer 1

Collecting rainwater for future use by storing it in storage reservoirs is called rainwater harvesting. In rainwater harvesting, the rainwater that falls on the roof and other parts of a building is channeled through pipes to an underground reservoir. These collecting pipes run along the sides of the roof and join together at a point to form the main pipe. This pipe flows into the tank present in the ground. The collected water may be allowed to seep inside the ground to recharge ground water or can be stored in tanks for future use.

Rainwater harvesting is one of the methods to deal with water shortage and meet the demands of water for the growing population. It also ensures water conservation and all round availability of water for various purposes.

Rain water harvesting structures include - Khadins, Nadis, Tal and Kulhs.
