meaning of Rainwater harvesting system

Rainwater harvesting system is a process of collecting and storing rainwater that falls on rooftops, land surfaces, or other surfaces, and using it for various purposes such as irrigation, household chores, and industrial processes. The collected rainwater is usually stored in underground tanks or above-ground containers, and it can be treated or filtered for safe use. This system helps conserve water resources, reduce runoff, and improve water quality.
