As Chennai reels under severe water shortage, Chennai Metro Rail Limited (CMRL) has begun turning off its air conditioners (ACs) in trains and stations during non-peak hours (between noon to 5 pm). As water levels in the four lakes near Chennai have recorded one of the lowest in 70 years, Chennai Metro decided to contribute their bit by dealing with the on-going water crisis.
The metro reportedly guzzles 9,000 litres of water a day with almost 80% of it going towards operating the air conditioning system. As per a report in thenewsminute, one Chennai Metro official said, “We switch on the AC system once in an hour to make sure we maintain 26 deg C at both platform and concourse levels. By switching off, we are able to save around 30% of water at every station. We ensure a temperature of 25 to 26 deg C is maintained in the trains. Every coach has two 41KV AC units. Our units in trains have been working efficiently and has so far not reported any failure.”
