The Cooper Center for Environmental Learning is a partnership between the University of Arizona's College of Education and the Tucson Unified School District. Cooper Center provides short camps and classes for TUSD students that emphasize hands-on experience of the natural world.

For this project, TFS crew partnered with TUSD plumbers to install a cistern connected to a pump which brings rainwater into their bathhouse to flush Camp Cooper's toilets. A simple float valve in the tank signals when rainwater in the tank is low, and triggers municipal water backup supply if needed. This project was made possible by a grant from the Central Arizona Project, from Cooper Center's fees and T-shirt sales, and the TUSD plumbing department. This system promotes Cooper Center's goal of continuing to reduce their facility's impact on the natural desert ecology they help their students discover every day.
