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.

Why do we need harvesting?

Rainwater harvesting is equally appropriate for large manufacturing units that use a large volume of 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.
