New-age tech helps save water




As the city grapples with unprecedented water scarcity, newage technology is helping residents save water.



Pipe nozzle fittings called aerators, once found only in green buildings, are now common in large communities along the Old Mahabalipuram Road. While an average tap releases 12-15 litres of water per minute, Eco365’s aerators cut this down to three litres, by reducing pressure of water flow.



Siruseri’s Eden Park community has installed Eco365 in all of its 650 apartments. “We installed them in kitchen sinks and wash basins, and have seen almost 55% savings in water,” said Somasundaram S, member of the Eden Park residents’ welfare association.



Bengaluru-based Neo Systek, the company behind Eco365, has seen a 30% growth in business from Chennai consumers this summer. “Our aim is to enable savings of one trillion litres of water by 2021, and with increased awareness, it is possible,” Peeyush Kothari, co-founder, Eco365, said.



IT major Cognizant recently fitted an innovative upgrade to taps called EcoMist by Chennai-based startup Earth Fokus. Cognizant has fitted these smart nozzles in restrooms and cafeterias across nine of its facilities in the city. “These nozzles reduce the water flow to a mist by atomising the water into fine droplets, bringing down water consumption by 80% and preventing wastage,” a Cognizant spokesperson said.



Earth Fokus has sold more than 8,000 of these in the last four months. “Our product can save almost 95% water without compromising on wash experience,” Roshan Karthik, co-founder of Earth Fokus, said.



With most residents buying water, another IIT-Madras startup Greenvironment is helping residents time these purchases with its software. Among other uses, Greenvironment’s sensors track water levels in tanks and send an alert when the level falls below 30%, thus helping the apartment place an order for the next lot. The tool also analyses working of treatment plants and provides alerts on abnormal results.



“We help users achieve a clear 30% savings in water footprint and improve water recycling,” Varun Sridharan, co-founder, Greenvironment, said.



Wastage of water due to accidental leakage and negligence is another common problem in households, and startups like Chennai based WEGoT Utility and Bengaluru’s Smarter Homes are helping minimize this with IoT-powered smart water meters.



Attached to inlets, these capture amount of water flow in real-time. A detailed consumption report along with other metrics are then shared with consumers via a mobile app. This also helps large complexes introduce a pay-as-per-use model for water and reduce water bills. Smarter Homes, which has at least 35 large housing communities in Chennai as its clients, also helps detect leakage and switch off the water supply remotely.
