उत्तर
‘Rainwater harvesting’ is the process of collecting and storing rainwater for future use. Rainwater can be collected in natural reservoirs or artificial tanks. Roof top harvesting is also a type of rainwater harvesting. The rainwater on the top of the building is collected and passed into the ground through pipes.
Water passing through the pipes enters the pit which consists of gravels and Coarse sand. As it passes impurities are filtered and stored as ground water.
Advantages of rain water harvesting:
- It increases the ground water level
- It can be used for agriculture
- It increases the availability of water for living things.
