Very interesting article in today's BM(attached below). In the heart of Jayanagar, Water is available at just 10ft in a house, which has plenty of free space leading to easy water percolation. At the same page gives the average depth of borewells across the city.

Today, every one covers with cement all the free space around their house, which has very very less benefit than leaving it as it is.
