The waste rate of treated water from apartments is 70–80%, as most of it goes down the drain.
Boson installs and operates the secondary treatment plant at the residential site, so the apartment incurs zero‑capex.
Industries pay less for Boson‑supplied water than they would for tanker‑delivered water.
Rainmatter, led by Vikas Brahmavar, backed Boson, signalling confidence in the model.
I decided to adopt Boson’s model because it turns an existing waste stream into a valuable industrial resource without requiring new infrastructure at the residential side.
These additions complement the earlier observations on water scarcity and highlight why Boson’s approach aligns with my strategy to fund hard‑problem environmental solutions.
In mid‑October 2026 I tweeted about the escalating water scarcity in Bengaluru and other fast‑growing Indian cities, focusing on how treated wastewater reuse can be a quick win.
Large apartments treat their own sewage, but only 20–30% of that water gets used, while 70–80% is discarded.
Boson supplies over 12 lakh liters a day to nearby industries for cooling towers.
Boson’s business model is to charge industries, apartments pay nothing.
Rainmatter’s investment in Boson, led by Vikas Brahmavar, reflects our commitment to hard‑problem environmental solutions.
I see this model as easily scalable to any Indian city where large residential complexes sit next to water‑intensive industries.
