उत्तर
Rainwater harvesting is a process by which we conserve rainwater. The rainwater is stored for reuse before it goes down the drain and gets wasted. The water which falls on the roof of a house is collected in an underground tank through a drain pipe. From the tank, water is purified and reused.
This water can be used for irrigating plants, cleaning, washing, etc. The conserved water can also be used for the purpose of drinking if the tank used for storing the harvested water is completely cleaned.
Few of the advantages of rainwater harvesting are:
- Rainwater harvesting requires a very small amount of maintenance. It provides free water which can be used for various purposes at a very low cost.
- Rainwater thus collected can be used for various domestic purposes such as drinking, cooking, bathing, washing, laundry, etc.
- This water can also be used for irrigation and provides regular water supply in drought-prone areas.
- Rainwater harvesting also reduces the risk of flooding of roads in cities as collecting rainwater reduces excess of water to get wasted.
