Why Rain Water Harvesting?
What is Rain Water Harvesting and the need for it
Rain Water Harvesting and Water Security
Most cities need not be water deficient, if only they adopt Rain Water harvesting at a large scale. The reason is that most of them receive more rain than their water requirement. A case in point is Bengaluru. The city gets far more rain than its water requirements. Therefore if Bengaluru becomes Zero Rainfall Outflow city, it can be 100% self sufficient with respect to water. Hence, Bengaluru need not be on the list of cities that will run out of Groundwater.
