Rainwater harvesting is collecting the run-off from a structure or other impervious surface in order to store it for later use. Traditionally, this involves harvesting the rain from a roof. The rain will collect in gutters that channel the water into downspouts and then into some sort of storage vessel.

What is rainwater harvesting answer in short?
Rainwater harvesting (RWH) is the collection and storage of rain, rather than allowing it to run off. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit (well, shaft, or borehole), aquifer, or a reservoir with percolation, so that it seeps down and restores the ground water.

Such industries can reduce the pressure on groundwater by making use of rainwater. … The use of rainwater harvesting systems allows groundwater levels to recharge, which in turn aids in enhancing urban greenery.
What is rainwater harvesting explain with diagram?
Rainwater harvesting can be done in the following ways: The catchment is an area from which the rainwater flows directly into a river or any other reservoir. Water can be stored either from the roof top or from the ground. … After filtration, water in the tank then can be used for domestic consumption.
