Soap Nuts are a natural berry shell that release saponins or soap when placed in water. You can use them in your laundry by simply putting four or five of them in a muslin bag along with the rest of your clothes. They can be used up to ten times making them extremely cost effective, especially compared to other organic detergents.

2018 Gloria Barron Prize for Young Heroes Recipient









California Youth Wins National Award for Heroic Service Activity


Boulder, CO, September 17, 2018 – Shreya Ramachandran, age 14, of Fremont, California, has been named a winner of the 2018 Gloria Barron Prize for Young Heroes. Each year, the Barron Prize celebrates 25 inspiring, public-spirited young people from across the U.S. and Canada who have made a significant positive difference to people and the environment. Fifteen top winners each receive $10,000 to support their service work or higher education.         

Shreya founded The Grey Water Project (www.thegreywaterproject.org), a non-profit that promotes the safe reuse of grey water and water conservation as a way to address drought. She works tirelessly to educate others about grey water – the gently used water from household sinks, showers, and laundry – and to remove the stigma that it is unclean and unusable. She has learned the California Plumbing Code and conducts seminars to show others how easy it is to build “laundry to lawn” grey water systems using organic detergents such as soap nuts. Soap nuts are a natural berry shell that release soap when placed in water. They are cost effective as a laundry detergent and are readily available around the world.

Shreya began her work with painstaking research on the environmental safety of soap nut grey water, concluding after three years that it doesn’t harm soil, plants, or aquatic life. She is now collaborating with several California water agencies to promote grey water reuse. She has earned numerous awards for her work, including the President’s Environmental Youth Award, and was invited to partner with the United Nations’ Global Wastewater Initiative. She is currently developing a grey water curriculum for elementary students to teach water conservation and the idea that small actions can make a huge difference. “I’ve learned that even though I am young, I can make a positive impact in my community,” says Shreya. “If I want to change something, I have to go out and make that difference instead of waiting for someone to do it for me.”   

 The Barron Prize was founded in 2001 by author T. A. Barron and was named for his mother, Gloria Barron. Each year’s 25 Barron Prize young heroes reflect the great diversity of America. They are female and male, urban and rural, and from various backgrounds. Many of them have focused on helping their communities and fellow beings; many others have focused on protecting the environment.
  “Nothing is more inspiring than stories about heroic people who have truly made a difference to the world,” says Barron. “And we need our heroes today more than ever. Not celebrities, but heroes – people whose character can inspire us all. That is the purpose of the Gloria Barron Prize: to shine the spotlight on these amazing young people so that their stories will inspire others.”

What is Grey Water?

​​​My Mission

There’s three types of water. White Water – This is clean water.  Grey Water – This is a form of waste water, but it never comes in contact with human waste. This water typically comes from sinks, showers, baths. Black Water – Another form of waste water that contains human waste. This comes directly from your toilet
