Good News
Chennai startup EarthFokus has helped 130+ buildings save over 5 billion litres of water by catching hidden leaks
Born during Chennai's 2019 water crisis and incubated at IIT Madras, it uses smart meters and AI to spot waste.
In short
5B+litres of water saved
- Buildings: 130+
- Water saved: 5 billion+ litres
- Tap flow: down to 0.5 L/min
The idea
EarthFokus was founded in 2019, during Chennai's 'Day Zero' water crisis, and is incubated at IIT Madras. Its WaterOS system uses internet-connected meters and AI to flag unusual flows; a steady flow at 2 am, for example, can reveal a running toilet. Its fixtures can cut tap flow from 10–12 litres a minute to as little as 0.5.
The results
More than 130 buildings use it. WeWork India cut water use from 45 to 29 litres per person per day, and Cognizant's Chennai campus reportedly cut daily demand by nearly 80%.
