Define rainwater harvesting.

Rainwater harvesting is the process of collecting and storing rainwater that falls on rooftops, driveways, and other surfaces for later use. This water can be used for irrigation, flushing toilets, washing clothes, and other non-potable uses, reducing the demand on municipal water supplies and lowering water bills.

Rainwater harvesting is the collection and storage of rainwater for reuse in order to reduce the demand on natural water resources. Rainwater can be harvested from any surface that collects water, such as roofs, driveways, and parking lots. The water can then be stored in tanks, cisterns, or underground aquifers. Harvested rainwater can be used for a variety of purposes, including irrigation, washing cars, and flushing toilets.
