WEF Guide to Managing Peak Wet Weather Flows in Municipal Wastewater Systems – Guidance Practices

The Water Environment Federation (WEF), under a Water Quality Cooperative Agreement with the U.S. Environmental Protection Agency, is developing a WEF guidance document focused on effective practices for managing peak wet weather flows at municipal wastewater treatment facilities. The guidance document is intended to address several wastewater industry informational deficiencies about wet weather and related technological solutions. The Guidance Practices section of the document provides a clear and common understanding of what may constitute “generally accepted practices” and long-term criteria. The section presents protocols for selecting wet weather management practices from the universe of available traditional and evolving technologies. The practices are organized by process Planning, Managing, and Operating and Maintaining. The guidance presents principles and examples applying the principals to select practices appropriate to specific wet weather management cases.
