Swajal's Sweet Water

Penn Stater Advait Kumar, an electrical engineering alumnus, founded Swajal, a water purification system he's bringing to poverty-stricken areas of India.

In 2008, Advait Kumar, a Penn State Electrical Engineering alumnus, saw something that changed his life. “One day I went to the backyard and I saw all these house workers queuing up to get their turn to fill water from our home. I didn’t understand why they were there."

The problem, hidden behind ancient, turquoise temples, is that scores of Indians are barely surviving life in terrible slums that are not recognized by Indian society. “The government,” explains Kumar, “isn’t even responsible for sending water or electricity or sanitation." 

21 percent of communicable diseases in India are water related. 

The situation is grave in Kanpur, Kumar’s hometown.  An industrial city with a population of more than two million people, it has carved out a niche in tanneries.  Most of the factories line the Ganges, which, in addition to being the holiest body of water in the Hindu religion, is where they discharge their waste unchecked.

“The dumping is mainly unrestricted by the government,” says Kumar. 

Still, children continue to swim in the river. “They play in the mud and then they die because of diarrhea. 1600 people a day die of diarrhea.  21 percent of communicable diseases in India are water related. These things,” says Kumar, “are curable.”

Swajal is a rigorous nine-stage purification system to clear water from the ground to the bottle. 

At Penn State, Kumar didn’t forget the abject poverty he’d left behind. When, in 2011, the United Nations put out a call for proposals for making clean energy accessible, he seized the opportunity. Swajal, a solar water purification system, was born.

It’s a rigorous system, which is critical when dealing with industrial contaminants. “We use nine purification stages to clear water from the ground to the bottle. And it’s customizable, depending on the contaminants. Ammonia and E. coli require especially rigorous purification. In an area where the water isn’t as bad, the system might be smaller.”

“She calls it sweet water. She says she doesn’t want to drink anything else.”—Kumar, speaking about a local Indian woman

Kumar, who built Swajal water kiosks while still a student, leaned on the Penn State community for support, drawing on his electrical engineering studies to build a system that met two essential criteria: precise engineering and green technology. “Basically, I had to connect all of these dots to build a solution.  Electrical engineering is a core engineering discipline. When you get good in electrical engineering, you can go and build something.  It’s like using Lego blocks."

Currently, Swajal employs between ten and fifteen people. The Swajal business model aims to empower locals by facilitating small business loans. Advait believes it's working. One Swajal owner has even created water debit cards.

"From speech classes to English classes to engineering, all of them helped me actually write a proposal that the United Nations accepted."—Advait Kumar

“But at the end of the day,” he said, “this is a social adventure, and I have to apply to the United Nations and other big organizations. Part of Penn State was learning how to write an effective proposal. How to tell people what you need and what is good. From speech classes to English classes to engineering, all of them helped me actually write a proposal that the United Nations accepted."

Since his May 2014 graduation, Kumar has continued to impact the quality of life in India, installing Swajal kiosks in four different states. Though he works at a major financial firm, he continues to mentor other social entrepreneurs coming on board.

“Swajal is essentially a platform and a franchise. I’m not interested in getting into the business of water. I want to create a web of super cheap water distribution centers."

Kumar's been overwhelmed by the support of local communities. "Swajal has really been internalized by them. Even though the systems are outdoors all day and all night, none have been vandalized."

In fact, a local woman scolded him for spoiling her with such good water. “She calls it sweet water. She says she doesn’t want to drink anything else.”
