Description
Mandovi motors of Karnataka has come up with an innovative idea to meet its huge demand of water for servicing cars. The idea is based upon the basic observation that the roof of the workshop covered a huge area and thus could collect a substantial amount of rainfall. Quoting from the source article It covers an area of 360 square metres. Calculating at the rate of 3500 mm average rainfall of this district - Dakshina Kannada – the roof catches 12, 60,000 litres of water.
Since the available rainwater was abundant, they had to dig out a large infiltration pit around the casing pipe of the borewell - 15 feet length, 12 feet breadth and 5 feet depth. Using boulders, granite stone pieces and sand - all filtering materials - the pit was refilled. Later it was covered with a strong iron lid so as to permit vehicles to run over it.
