RAINWATER HARVESTING
RWH is the technique of collecting, storing and distributing rainwater for multiple uses. The collected water can be stored for direct use or diverted for borewell/groundwater recharge. In simple terms it is a way to capture the rainwater when it rains, for later use.
WHY HARVEST RAINWATER
Water Crisis is common in Urban and Rural areas in India. This is more felt in urban areas due to population concentration. In hilly regions, even though water is available in limited quantities, crises are handled due to the drying up of the sources.
Rainfall is one of the important source of fresh water is a significant throughout the Country. Rainwater Harvesting is one of the important solution to mitigate the water crisis as the copious volume of water goes waste during the rainy season.
Thus Rainwater Harvesting and Artificial Recharge of Groundwater have to be adopted to provide sustainability to the water supply.
HOW TO HARVEST THE RAINWATER
Any Rainwater Harvesting system has three components: Catchment, Conveyance, and Storage. There are two classes of Rainwater Harvesting systems:
- Systems which collect roof runoff for household use.
- Systems which use in field or adjoining catchment to provide supplemental irrigation for Agriculture.
