In India, rain water harvesting was first introduced by Andhra Pradesh ex-Chief Minister N. Chandrababu Naidu. He made a rule that every house which is going to built in cities of that state must have a percolation pit/rainwater harvesting system. This rule increased the ground water level in good phase. After his term as Chief Minister, the next leaders neglected this system. In the state of Tamil Nadu, rainwater harvesting was made compulsory for every building to avoid ground water depletion. It proved excellent results within five years, and every other state took it as role model. Since its implementation, Chennai saw a 50 percent rise in water level in five years and the water quality significantly improved. In Rajasthan, rainwater harvesting has traditionally been practiced by the people of the Thar Desert. There are many ancient water harvesting systems in Rajasthan, which have now been revived. At present, in Pune (in Maharashtra), rainwater harvesting is compulsory for any new society to be registered. en.wikipedia.org/wiki/Water_harvesting
