The Water Board supplies 340 million gallons of water every day in the city, but is collecting bills for only 220 MGD. It does not have an account of 120 MGD of water it is supplying daily in the city. As a result, the Board is getting revenue of only Rs 35 crore per month for 220 MGD, and is losing another Rs 15 crore that it should be getting for the 120 MGD that is unaccounted. Officials said this huge quantity of water is going waste due to leakages in the distribution system, and also due to a large number of illegal connections.
