On World Water Day on Saturday (March 22), the residents of Nagarjuna Pearl Bay Apartment at Kadavanthra will go in for a water audit — an audit of how much water each household needs and the real usage. It was the huge recurring costs of water that led the residents’ association of the apartment comprising 226 units to look into the issue.

As per the figures arrived at by the United Nations, an individual requires 526 litres of water a day. The apartment gets 25,000 litres of water from the Kerala Water Authority and they have to buy three tanker lorries of water of 22,000 litres each to tide over their daily needs. The monthly cost of water is a staggering amount at Rs. 1.5 to Rs. 2 lakh.

A workshop will also be conducted by the SCMS College of Engineering that will help residents understand how much water is required for their daily activities and how much can be conserved by adopting various methods.

“We want to set an example in water conservation and this is just the beginning,” said association secretary T.S. Ramaswamy. “There is no water audit in any apartment here. Every apartment goes in for deeper bore wells, thus exploiting the ground water in the area. There are only a handful of apartments where they do not buy water by exercising restraint in pumping,” he said.
