What is the technique of rainwater harvesting class 10?

One of the most widely used methods of collecting rain water is rooftop rainwater harvesting. In a rooftop rainwater harvesting system, rain water falling on the roof is collected and then filtered before being stored in tanks for immediate use. Excess water is diverted to wells to recharge groundwater.
