Between the rise of green infrastructure, the effects of climate change, increasingly complex regulations, and the seemingly endless pursuit of infrastructure funding, the stormwater management sector is more dynamic than most public services. Stay on top of new trends, studies, and developments that shape the stormwater sector with these resources.
The Fourth Iteration of the WEF National MS4 Needs Assessment Survey has Launched!
MS4 Needs Assessment Survey
The Water Environment Federation (WEF) conducted its fourth national Municipal Separate Storm Sewer System (MS4) Needs Assessment Survey in 2024, with data collection extending into 2025 to achieve robust national representation. The survey was designed to better understand the challenges, priorities, and resource needs shaping MS4 stormwater programs across the United States.
The survey results provide critical insights into program funding, workforce capacity, asset management, regulatory drivers, and emerging challenges facing both traditional and nontraditional MS4 permittees. Findings from this effort support national advocacy, inform technical assistance priorities, and help elevate stormwater as a distinct infrastructure sector.
The 2024 MS4 Needs Assessment Survey Results are now available as a technical report on Access Water and are freely accessible to both members and non‑members.
The Stormwater Community annually hosts the National Stormwater Policy Forum to advance the latest legislative and regulatory concerns of the stormwater sector legislators and regulators. This outreach includes creating the Recommendation to Improve the Stormwater Program In the U.S. document that stormwater advocates can use year-round.
Based on input from leading stormwater professionals, this report details the challenges, opportunities, and pathways to improving the nation’s stormwater systems to make them more efficient, effective, and sustainable.
Stormwater, Watershed, and Receiving Water Quality Modeling
This special publication presents state-of-the-art stormwater modeling and is a practical tool that presents a broad compilation of existing models, their capabilities, and a roadmap for users to assist in the selection of such models for diverse applications.
Urban Stormwater Controls Operation and Maintenance
WEF Manual of Practice No. 39 includes the best practices for the continued operation of stormwater control measures (SCMs) for your stormwater programs. The material covered will be of particular use to designers of SCMs, utility managers, and O&M staff.
This book provides actionable information promoting the implementation of green infrastructure. Unlike most publications, which focus on technical design of individual green elements, this peer-reviewed book tackles topics related directly to the ability to implement green infrastructure.
