Urban

Urban water harvesting in India is still in its youth. There are a number of people who worked, against all odds, to make this concept popular. They, the Harvesters, can be found in most urban centres in India

Experience is the best teacher…

There are no limits to technological innovations in rainwater harvesting. Innovators are those who have learned from their experiences and contributed to the betterment of rainwater harvesting technology in India.

Rural

Water improves agriculture. Agriculture improves animal husbandry. People begin to take care of their watershed, which means more trees and forests. With watershed development, prosperity beckons.

Going beyond water is a philosophy and a practice. Some have gone beyond water to alleviating, actually eradicating, rural poverty. They have dared to traverse the path from ecological regeneration to economic miracle, from water to wealth.

Those with this water vision overwhelmingly belong to civil society.
