Rain water harvesting is the accumulating and storing of
rain water for reuse before it reaches the aquifer. It has been used to provide
drinking water, water for livestock, water for irrigation, as well as other
typical uses. Rain water collected from the roofs of houses and local
institutions can make an important contribution to the available drinking water
it can supplement the subsoil water level and Increase urban greenery.
Major parts of our country have been facing continuous
failure of monsoon and consequent deficit of rainfall over the last few years.
Also due to ever increasing population of India, the use of ground water has
increased drastically leading to constant depletion of ground water level
causing the wells and tube Wells to dry up.
Due to over population and higher usage level of water in
urban areas, water supply agencies are unable to cope up demand from surface
sources like dams, rivers, reservoirs etc. This has lead to digging of
individual tube Wells by house owners.
