Recycling air conditioning condensation

Amid the acute water shortage in the city, Chennai Metro Rail is pitching in to do its bit. It has adopted a mechanism that will help save about 2,000 litres of water every day.

According to officials of Chennai Metro Rail Limited (CMRL), the condensed water dripping from the air conditioners will be collected and used for various purposes.

“For a start, this process has been tried in the administrative building of CMRL in Koyambedu. Soon, we plan to extend it to the stations along the underground stretch from Thirumangalam to Nehru Park,” an official said.

The administrative building alone consumes 40,000 litres of water per day, sources said. Stations on the elevated corridor and the underground corridor consume about 25,000 and 15,000 litres respectively.
