Uravu's water-from-air bet: liquid desiccant at 4,000+ L/day, ₹3/L, still scaling
Bengaluru's Uravu Labs extracts drinking water from air with liquid desiccant, betting unit cost can fall below ₹1/L for industrial buyers.
Uravu Labs
What the business is
Produces and bottles drinking water extracted from air using liquid desiccant (calcium chloride), selling to Bengaluru hotels and restaurants and piloting industrial-scale supply.
Starting capital：~$4.3M across five rounds (Speciale Invest pre-seed, AWE Funds-led round Oct 2024, last round July 2025), after a $50,000 Water Abundance XPrize finish in 2018
How it started
It began as a 2012 student project at NIT Calicut; after a top-five global finish at the 2018 Water Abundance XPrize, Swapnil Shrivastav, Venkatesh Raja and Govinda Balaji founded Uravu in 2019 in Bengaluru and spent about three years developing liquid-desiccant extraction.
What happened
Production scaled from 5 L/day in 2019 to 4,000+ L/day by 2024. Uravu signed an AB InBev pilot (2022), serves 55+ premium hospitality clients selling bottled air-water at ₹90–150/L, and raised ~$4.3M. FY25 revenue hit ₹4.2 Cr, up 293% from FY24, with pilots for data centres, distilleries, pharma and green hydrogen.
How it ended up
Still running and scaling: the last round closed 10 July 2025, and the roadmap targets 50,000–500,000 L/day industrial units at below ₹1/L; no shutdown or acquisition as of September 2026.
Background
Uravu Labs is a Bengaluru climate startup betting that drinking water can be pulled from air at costs that eventually beat trucked groundwater. Co-founded in 2019 by Swapnil Shrivastav, Venkatesh Raja and Govinda Balaji after a top-five finish in the 2018 Water Abundance XPrize, it uses a liquid desiccant (calcium chloride) instead of the condensation approach used by most atmospheric water generators.
The technology absorbs moisture from air and releases it with low-grade heat, claiming 300–400 Wh/L across 30–100% humidity versus 500–800+ Wh/L for condensation in dry conditions. Production grew from 5 litres per day in 2019 to more than 4,000 litres per day by 2024, sold to 55+ premium hotels and restaurants in Bengaluru at ₹90–150 per litre.
Uravu has raised about $4.3 million across five rounds, including a pre-seed from Speciale Invest, an AWE Funds-led round in October 2024, and a final round in July 2025. FY25 revenue reached ₹4.2 crore, up 293% from ₹1.1 crore in FY24. Pilots span AB InBev breweries and data-centre waste-heat reuse.
The open question is scale: the company targets 50,000–500,000 litres per day and a cost below ₹1 per litre, while water researchers caution that air-to-water cannot replace bulk urban supply. As of September 2026 the bet is still live, with industrial contracts the make-or-break test.
What has to be true
- The founding bet was technical: liquid desiccant over condensation, sacrificing build simplicity (three years of development versus 30 days) for energy efficiency and humidity independence.
- The market bet was that premium hospitality would pay for zero-carbon water while industrial-scale pilots (breweries, data centres, pharma) bring the cost curve down.
- Funding stayed small (~$4.3M) and grant-driven, keeping the company alive through long hardware cycles without forcing premature scale.
- Whether the category works depends on unit economics crossing the sub-₹1/L threshold, which remains unproven at industrial volumes.
What can be applied
A better process only wins if unit economics match what customers pay: ₹90–150/L bottled water is a niche, and the sub-₹1/L industrial target remains unproven — cost curves, not engineering, decide.
Aftermath
As of September 2026 Uravu remains an independent, scaling startup: it closed its most recent funding on 10 July 2025, reported ₹4.2 Cr FY25 revenue (+293%), and is working toward industrial deployments with data centres, distilleries, pharmaceutical plants and green hydrogen producers, alongside its premium bottled-water business in Bengaluru. No shutdown, pivot or acquisition has been announced.
