Question

4. Rainwater harvesting can be carried out by two ways. Name them.

Answer 1

• The process of collecting and storing rainwater in containers for later use is called rainwater harvesting.
• Rainwater harvesting can be carried out in the following two ways:

1. Pits and Tanks: Pits and tanks are dug in low-lying areas to collect rainwater. Sometimes, the collected water(after being filtered) is fed into the dried-up borewells to replenish the groundwater reservoir.
2. Rooftop rainwater harvesting: In this system, the rainwater is collected from the rooftop to the storage tank through pipes.
