But, the irony is that the water harvesting systems already installed in government are not being properly maintained and have rendered non-functional.
Ancient Rajasthan had been famous for rain harvesting in the form of step wells or bawaris which have become defunct due to modern water supply systems.
Rainwater harvesting is the collection and storage of rainwater for reuse for drinking, irrigation, washing and recharging the underground water table. Often, under a rain harvesting system, rainwater is collected from the roofs of houses and local institutions for reuse for various purposes and can be valuable contribution to the availability of drinking water and raising of water table.
Some developing countries have done a good job in rain harvesting. For example, in China and Brazil, rainwater harvesting is being used for providing drinking water, domestic water, water for livestock, water for small irrigation and replenishing the ground water levels.
