Vellore: The importance of rainwater harvesting (RWH) was stressed by Sekhar Raghavan, director, Rain Centre, Chennai.

He was delivering a special lecture on ‘Challenges in Water Conservation’ organised by the Department of Environmental and Water Resources Engineering of the School of Civil and Chemical Engineering (SCALE) of VIT University as part of the water conservation week celebrations in connection with World Water Day at VIT campus here on Wednesday.

Raghavan said floods created havoc in Chennai, Tiruvallur and Kanchipuram districts during the north-east monsoon in 2015 due to the failure to desilt and renovate water bodies - as also the failure to put in place proper RWH structures.

The groundwater level would go down because of the aquifers beneath the deep borewells, whereas the level would go up whenever the water level increases in open wells, he said. Therefore, he appealed to residents not to close down open wells in their houses.

Dr. Parimala Ranganayaki, Assistant Professor, Department of Environmental and Water Resources Engineering, and Dr Roshan Karan Srivastav, Associate Professor of the department, and the faculty coordinators spoke. Prof S Shantha Kumar, head of the department, welcomed the gathering.
