Experts say the underground water table is falling because of the prolonged dry spell.
The department concerned is supplying water to a few localities in urban areas once in 24 hours. An official of the Public Health Engineering Department said that 10 tube-wells out of 85 in the district had already dried up as the underground water table had fallen by 70 to 80 feet. About 25 water schemes out of 45 in the far flung hilly areas of the district have been abandoned.
