Post construction stormwater control measures (SCMs) are installed with the intention of meeting a specific water quality benefit over the life cycle of the SCM. Long term field monitoring studies exist for commonly deployed SCMs; however, differences in monitoring protocols, site variables, analytical methods and other parameters can dramatically influence performance and longevity assessments. Ideally, standard testing protocols would comparably quantify the operation and maintenance demands of various SCMs in a way that would allow designers and regulators to anticipate their life cycle cost projections. This presentation will compare existing lab and field test protocols to assess SCM maintenance intervals including the New Jersey DEP laboratory filter protocol, Washington’s Technology Assessment Protocol – Ecology (TAPE), and Oregon DOT’s Stormwater Technology Testing Center (STTC). Two new options will also be presented — one of which is a high precision, low frequency protocol that utilizes synthetic stormwater in a lab setting to more accurately mimic the long-term field response of SCMs. The second is a high frequency, low precision data collection effort that utilizes a widespread maintenance indicator sensor deployment to generate a database of operational records.
Session duration: 45 minutes
