Nagpur : Nearly half of Nagpur city is staring at an acute water shortage after the Kanhan River, swollen by heavy rains in Madhya Pradeshs Chhindwara district, disrupted operations at the Kanhan Water Works. Officials said the intake wells at the water works have been buried under a thick layer of sand, mud, and debris, drastically reducing the citys capacity to lift raw water. The heavy inflow has also submerged suction mouths and strainers, making pumping operations almost impossible.
