The elimination of runoff can reduce contamination of surface water with pesticides, sediment, metals, and fertilizers. By reducing stormwater runoff, rainwater harvesting can reduce a storm’s peak flow volume and velocity in local creeks, streams, and rivers, thereby reducing the potential for streambank erosion.

Perhaps the most important benefit of rain is its redistribution of fresh water in the water cycle.

Broadly there are two ways of harvesting rainwater, namely; surface runoff harvesting and rooftop rainwater harvesting. Rainwater harvesting is the collection and storage of rain for reuse on-site, rather than allowing it to run off.
How rain water harvesting can be done?
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.
