Stormwater Research Facility
About the Center
The Auburn University – Stormwater Research Facility (AU-SRF) is an internationally recognized 12-acre outdoor laboratory dedicated to conducting full-scale evaluations to improve practices used to manage stormwater runoff. This facility engages professionals in the stormwater industry through research, product testing and development, and hands-on educational events.
The AU-SRF was established in 2006 through a collaboration between Auburn University’s Highway Research Center and the Alabama Department of Transportation. It operates within the Auburn University Highway Research Center at the National Center for Asphalt Technology Pavement Test Track in Opelika, Alabama.
The AU-SRF leads the development of practical, engineering-driven stormwater solutions that are recognized as best practices in the field. Through hands-on training opportunities, workshops, and field days, the facility helps bridge the gap between theory and real-world application. These efforts empower stormwater professionals, policymakers, and local communities to adopt effective, science-backed practices that improve water quality and protect natural resources.
