The poverty-alleviating method, an “ultra low-cost approach” that she aims to launch in India, would reduce the cost of enriching drinking water from $50 to $1 per person, Cherukumilli said.

Cherukumilli, who was born near the district, immigrated to the United States as a young child with the rest of her family.

Cherukumilli was one of five finalists selected by a panel of judges from among 35 entries submitted to the contest, which sought proposals that could help people living in poverty, reported the Orange County Register.

While the competition had initially sought one winner, UCI professor and Blum Center director Richard Matthew told Daily Pilot that organizers were excited about several of the ideas and decided to award second- and third-place winners as well…
