Rainwater harvesting means collection of rainwater and to store it in different containers applying proper means to keep the water fit for any use.
The rainwater may fall anywhere on the earth, but that must not be allowed to roll or run downwards to get evaporated or to seep into dirt or filth and thus become unfit for use.
The main purpose of keeping the rain water conserved is the ponds, channels, ditches, canals, etc. is to recharge the groundwater with this surplus unused water. This conserved water is lifted up with the help of deep or shallow tube-wells to be used as drinking water or to be used in agriculture.
Uses: The water that collected through rainwater harvesting is used for several purposes.
This reserved rainwater can be properly filtered and treated to be used as drinking water.This water is stored up in ponds, ditches, canals, etc. in the rural areas for using in everyday household chores as well as in agriculture also.The subterranean water in some areas are not drinkable due to it’s high arsenic percentage. To mitigate this problem in those areas, rain-water is conserved carefully to be used as the substitute for drinking water.
Methods: There are various methods for Rain water harvesting.
Water can be stored in a reservoir on or under the surface. The stored up water is later on taken to places with the help of pipe or tube or container.Ponds, canals, big ditches or water-courses, etc. in the country-sides are filled up with the rain-water to replenish the subterranean water-storage subsequently.Water can be stored in medically treated and carefully built subterranean reservoirs that can be used in emergency.

Rain water harvesting is the collection of rainwater into the man made resources or any natural resource like pond, lake, etc at the same place where it falls from rooftops or ground. Two main techniques of rainwater harvesting are storage for future use and recharge into the ground. It can be used for crop harvesting, gardening, toilets, etc. Following are the benefits of rainwater harvesting at individual or city-wide level:
It helps in reducing the water supply bills especially to the institutions.Rainwater recharged to the ground positively affects groundwater quality by diluting fluorides, nitrates and its salinity.It contains almost neutral pH and zero hardness which makes it more able to be used in homes, industries, institutions and other commercial establishments.It may reduce the stress of public water supply sources.Recharge of rainwater to the ground prevents sea-water immersion into the fresh water bodies in the coastal areas.It helps in controlling urban flooding if people do rainwater harvesting from rooftops.It reduces water demands of people from the municipality thus lessens energy consumption too in distributing water all through the city.
