`Retas': A mission to harvest every possible raindrop

Around 4-5 years ago, Ankit Magan, Neeraj Chauhan, and Priyank Jain held up in traffic caused by the flooded streets during the monsoon season. "We realized that all that rainwater was going to drainage was wasted. This experience is when building something sustainable popped into our heads," Ankit says. Retas's Rainmaxx tanks are made of recycled polypropylene and are very easy to maintain. The water tank has pre-filtered units fixed on its surface, with various filters that filter the rainwater before entering it. Inside the tank, a porous synthetic material called geotextile is fitted. Geotextile acts as an extra filter that allows only the water particles to penetrate. "Retas is a Sanskrit word for a raindrop. Our primary vision is to conserve and harvest every possible raindrop. To keep working as a catalyst until rainwater becomes a natural resource for everyone," he says.
