Jaipur is staring at a serious risk of running out of water in a month if there is no rain, according to the Rajasthan Public Health Engineering Department. The main source of water, Bisalpur dam, that caters to the needs of the mostly dry city with a population of over 30 lakh - which the UNESCO added to its famous World Heritage Site list last month - has enough water to last only a month. The dam has a full capacity of 1,095 cusec metres; the current water level is 64.93 cusec metres, or 5.93 per cent.
