Overview of EPA's wet-weather flow research program

This paper presents an overview of the US Environmental Protection Agency's (EPA's) wet-weather flow (WWF) research program. Research priorities for 2001 are presented. In 1996, EPA issued the “Risk Management Research Plan for Wet Weather Flows”, a plan that presents specific WWF problems and anticipated research approaches to solve them. Within each area, the state-of-the-art knowledge is presented and the unknowns cited; research questions to address the unknown are also posed. In the time since November 1996, other organizations, notably the Water Environment Research Foundation (WERF), have reviewed WWF research programs and developed associated research needs reports.
