Recently, I wrote about how serious our water problem is getting. This year’s weak monsoon has made it worse, and in Bengaluru, for example, that means dry borewells and expensive tankers. But we’re also wasting water we’ve already cleaned.

Large apartments have to treat their own sewage, but only 20–30% of that water gets used. The rest goes down the drain. Meanwhile, IT parks and factories a few kilometers away are buying tanker water for their cooling towers.

Bosonwhitewater takes the treated water apartments don’t use, cleans it up for industrial use, and supplies it to these businesses. More importantly, they’ve made a business out of it.

Boson sets up and runs the plant, so the apartment pays nothing, and industries pay less than they would for tankers. Today, Boson supplies over 12 lakh liters a day.

This isn’t just a Bengaluru problem. Every growing Indian city has apartments and industries close to each other, and reusing treated water is one of the easiest wins we have.

We need more people working on hard problems like this. That’s also why we’ve backed Boson and Vikas Brahmavar through Rainmatter.

If your apartment is letting treated water go down the drain, this is worth a watch 🙂
