The project, which prioritizes greywater for toilet flushing, is a finalist for the Discovery Education 3M Young Scientist Challenge
A 14-year-old from Sugar Land, Texas., has developed a toilet flushing system that uses both fresh and recycled water to reduce water consumption in the home. The student, Mehaa Amirthalingam, has been named a finalist in the 2018 Discovery Education 3M Young Scientist Challenge for her innovative water reuse system.
The system blocks the flow of fresh water to a toilet tank after each flush, instead allowing greywater to enter the system from other home appliances. When greywater is not available, the mechanical device automatically allows fresh water to fill the tank. Amirthalingam hopes that installing her device in homes across the U.S. will reduce water consumption.
The Young Scientist Challenge is a collaboration between Discovery Education and 3M which recognizes students in grades six to eight who show curiosity into the scientific process. The challenge invites students to submit videos that describe an invention or idea that could solve an everyday problem. All finalists receive the opportunity to work with 3M scientists during a summer mentorship program to develop their ideas. The winner will receive $25,000, a trip to watch the taping of a Discovery Network show and the title of “America’s Top Young Scientist.”
