BHOPAL — At least 66 towns in the central state of Madhya Pradesh are getting drinking water every alternate day and 56 every two or more days, in one of the worst droughts to hit the region in recent times. Even in capital Bhopal, where the water supply is available daily, the duration is hardly for 15-30 minutes. Officials say even this might not last for long. “It will be difficult to maintain this after June 8,” said a senior civic official. The state government has spent more than 8.4 billion rupees to fight the drought, which has hit at least 22,000 villages in 32 districts. It has started relief operations that employ an estimated 1.2 million people. A large number of old lakes and other sources of water have been revived and some of them have been recharged during the brief spell of rains that hit the state mid-May.
