===Bangalore example===

In Bangalore, water will be purchased from private water tankers and stored to be used for construction. One estimate says there a million sumps in the city alone with an average capacity of 6000 litres. This means that the water storage capacity created is a staggering 6000 million litres. Remember that the city gets in about 1000 million litres every day. Added to the fact that there is about 1000 million litres stored in overhead tanks the water storage by the city far outstrips that created by the utility.

The ideal system in Bangalore is one where rainwater is stored in sumps and the surplus used for recharging borewells.
