The 136-year-old Red Hills reservoir, one of the city’s major primary drinking water sources, is set to be improved after several decades. The Water Resources Department (WRD) has not taken up any major project at the reservoir since 1994, except for maintenance work worth Rs.5 lakh every year.

The WRD has now called for a tender for the project, worth Rs. 10.16 crore, to strengthen the reservoir. The water level in the reservoir now stands at 8.43 feet. The department has not stepped up the level for a few months now, in order to facilitate repair work.
