Sustain-A-Drain Team Wins $15,000 EPA Grant

A team of students from the University of California, Riverside Bourns College of Engineering received a $15,000 grant from the Environmental Protection Agency for a reusable storm drain filter.The key innovation is the calibrated indicator and filter system. The filter is made of 100 percent recycled textiles. The indicator is a 3-D printed device made with the same material as the filter and a translucent biodegradable plastic. An included polymer changes from powder to gel when saturated with oil and/or heavy metals, indicating the need for replacement.The filter material is a blend of 100 percent recycled polyester, rayon and cotton fibers.
