Rainwater Reuse System by Ishu,10th class, Adarsh Senior Secondary School

Rainwater Reuse system or Rainwater Harvesting

A rainwater reuse system 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 reservoir with percolation so that it seeps down and restores the groundwater. Dew and fog can also be collected with nets or other tools. Rainwater harvesting differs from stormwater harvesting as the runoff is typically collected from roofs and other surfaces for storage and subsequent reuse. Its uses include watering gardens, and livestock,[3] irrigationdomestic use with proper treatment, and domestic heating. The harvested water can also be committed to longer-term storage or groundwater recharge.
Rainwater harvesting is one of the simplest and oldest methods of self-supply of water for households, having been used in South Asia and other countries for many thousands of years. Installations can be designed for different scales including households, neighborhoods, and communities, and can also be designed to serve institutions such as schools, hospitals, and other public facilities [6]
