Impact/Purpose:
To present an updated review of the state of the science in the conduct of stress testing at municipal wastewater treatment plants.
Description:
Treatment of peak flows during wet weather is a common challenge across the country for municipal wastewater utilities with separate and/or combined sewer systems. Increases in wastewater flow resulting from infiltration and inflow (I/I) during wet weather events can result in operational difficulties for publically-owned treatment works (POTWs) and compromise proper treatment and compliance with discharge permits or receiving water criteria. Thus, a need can exist for POTWs to increase peak wet weather capacity while protecting the functionality of sensitive unit treatment processes. This reports presents an update on the current stress testing approaches being applied across the country and summarizes those approaches into a protocol for potential demonstration by EPA ORD.
