The Stormwater Technology Testing Center

The stormwater Technology Testing Center (STTC) is a testing facility located in Portland, Oregon that is dedicated to evaluating the pollutant removal performance, maintenance requirements, and life-cycle costs of emerging stormwater treatment technologies. The STTC was designed and constructed by ODOT in collaboration with numerous public stakeholders in Oregon and Washington. In 2023, the STTC began full-scale testing of proprietary technologies. For more information on how to apply to test your product at the STTC or obtain testing results, please visit the STTC website.
