Teen Scientist Finds a Low-Tech Way to Recycle Water

A 17-year-old girl named Shreya Ramachandran recently founded a nonprofit organization teaching people to recycle water in their homes in California. She was inspired by the water shortages in the state’s Central Valley.

“I was talking to some of the people in the area whose wells completely ran dry, and they were left without water because they weren't connected to the central water grid. They were trucking water in for even basic needs,” she tells Discover. “I was really affected by their stories, and I wanted to do something to help.”

She researched ways to reuse graywater from sinks, showers and laundry machines to help people cope with droughts. She has won awards for the research and was named a finalist in the 2019 Google Science Fair. She’s also featured in an upcoming PBS documentary about climate change titled “The Power of Us.”
