It is the collection of rainstorm-generated runoff from a particular area (a catchment) in order to provide water for human, animal, or crop use.
When it rains a lot, water pours into the streets, drains, and we can't use them.
Our goal is to collect this rainwater and store it for later use when we need it.
It is a solution to conserve depleting groundwater.
Process of rainwater harvesting:
Rainwater is collected through pipes from the roofs and verandas of buildings and redirected to tanks, cisterns, deep pits, aquifers, or a reservoir with percolation so that it seeps down and restores the groundwater.
