This start-up creates ‘green’ water out of thin air and sells it at ₹4 per liter
- Capital is pouring into the renewable energy sector, thanks to a growing awareness of climate change.
- The industry is expected to grow to $1.9 trillion by 2030 as every aspect of the energy supply chain gets reimagined.
- Many clean-tech start-ups have cropped up in the renewable energy space.
Uravu Labsis one of them that’s known for creating sustainable water out of thin air.
- It is now on its path to making water sustainability a reality for beverage conglomerates such as Coca-Cola, Radico Khaitan, Kirin Holdings, Suntory.

Groundwater, which supplies 85% of drinking water in rural areas, is depleting at an accelerating rate -- taking away their primary source of water and threatening India’s food security.
“There was a time when we were just allowed to have one bucket per day in college because there was a severe drought for a couple of months,” recalls Swapnil Shrivastav, co-founder of a clean-tech start-up.
He decided to find a solution to this problem with his college friend Venkatesh R.
To help fight water scarcity, Shrivastav and Venkatesh worked on a machine that produces sustainable drinking water from air and bootstrapped ‘Uravu Labs.’
Water from thin air that leaves no carbon footprint
The water-from-air concept is not new. The conventional method however uses a significant amount of electricity to harness it and is nt always generated from clean, renewable sources.
“To make one liter of water, conventional tech used almost four units of electricity. One unit of electricity is around eight to 10 rupees,” shares Shrivastav.
The cleantech founders took it upon themselves to find a sustainable solution to water scarcity and offer it at the same price point as mineral water Bisleri.
That’s how Uravu was born. It now uses desiccant-based technology that directly absorbs water from air and is powered by solar energy and even industry-based waste heat.

Renewable water at ₹4
It produces 20-100 liters of water per day by extracting it from thin air. Their renewable water is priced almost the same as mineral water at around six rupees per liter.
As they scale up, the water can become cheaper. At 100-200 liters extraction per day, the cost is around ₹4.
“When we go to industrial scale, say at 2000-10,000 liters and beyond, the costs will come down to just ₹2-2.5 per liter,” says Shrivastav.

Uravu Labs, which is now in the early stage of commercialization and deployment, has been targeting beverage brands in India.
The beverage industry requires the highest amount of water and electricity to make its products. Cold drinks and beer, Shrivastav said, are more than 90% water.
Beverage giant Coca-Cola consumes more than 10 lakh liters of water per day.
“Overall, the beverage industry withdraws more than 1,500 billion liters of water on an annual basis, which is equivalent to 20% of human drinking water needs on an annual basis. More than 45% of this 1,500 billion liters is coming from groundwater, which takes around 1,400 years to replenish,” shares Shrivastav.

So, instead of relying on groundwater, Uravu is now helping beverage brands such as AB InBev, Moonshine Meadery, Coca-Cola, Radico Khaitan, Kirin Holdings and Suntory switch to extract water from air with their pilot technology and bring their carbon footprint to zero.
Expanding its reach beyond the country
Uravu is also casting its net wider by targeting the real estate industry including individual villas, office buildings, parks, schools and hospitals.
Sharing the roadmap ahead, Shrivastav says, “In four to six months from now, we aim to have 100 liter [production tech] per day. The idea is to scale it up to more than thousands of liters over a period of time and add more resources. In the short term, we are focusing on 20-100 liter per day units.”
