India is facing a major water crisis and a number of water sector challenges remain unaddressed even today.

India is on the brink of a major water crisis. With drought looming over the southern and western parts of the country, the existing water resources are in peril. Rivers are getting more polluted, their catchments, water-holding and water-harvesting mechanisms are deteriorating and groundwater levels are depleting at an alarming rate.

The polluted Erai river needs to be restored before it completely dies and leaves the people dependent on it searching for drinking water.

The Erai river, the main tributary of the Wardha river, is the lifeline for the people of Chandrapur in Maharashtra. It primarily supplies water to the Chandrapur city and Chandrapur super thermal power station (CSTPS). Since 1984, after the initiation of operations of M/s CSTPS and Western Coalfields Limited (WCL), the river has begun to get polluted and is now gasping for breath.
