Urban Rainwater Harvesting
Collecting natural resources
Dr Vishwanath Srikantaiah, a water activist and urban planner, in collaboration with several communities has carried out successful campaigns at the household level and some with large community participation to conserve water in Bengaluru.
Bengaluru is one of the 21 cities of India which will run out of water by 2020.
The city like other Indian cities suffers because of rampant concretization of the ground which limits water going into the ground.
To counter this, recharge wells are constructed. The recharge wells direct the water into aquifers which recharge the ground water.
This also guarantees livelihood to traditional well diggers who lost their jobs due to mechanization of well digging.

His expertise has yielded calculations which people and communities can use for rainwater harvesting.
For every square metre of roof area, one has to create 20 liters of storage of recharge, and for every square meter of the paved area around the building, one has to create 10 liters of storage of recharge. The recharge well should be a minimum of 10 feet,
His efforts started in 1995 when he started spreading the information about rainwater harvesting
