What is Rainwater Harvesting?

 , updated on
Rainwater harvesting is the capture of rainwater for onsite use as opposed to allowing it to become runoff. Captured water may be used for gardens, irrigation, household use such as toilets and cooling systems. Properly treated, it can be made potable and used for drinking and food preparation.
In areas where fresh water is a scarce resource, rainwater is an important source of water. In other areas, rain water harvesting reduces water consumption and improves resilience to disruption of a main water supply. It may also reduce pollution of fresh water sources as runoff typically becomes polluted on its way to a river, lake or ocean.
