Stormwater refers to rainwater or snowmelt that travels over impervious land surfaces as runoff. Stormwater pollution results when this runoff picks up, carries and transports various pollutants (oil, grease, chemicals, sediment, nutrients, pathogens) along streets, drains, open channels, and storm sewer systems. This runoff is eventually discharged untreated into nearby water bodies. However, in combined sewer systems, stormwater flows with sewage to a wastewater treatment plant.
In urban areas, stormwater management is especially important due to decreases in natural land cover and the expansion of impervious surfaces, such as rooftops, sidewalks and roadways. These surfaces exacerbate runoff because they change the permeability of the landscape—preventing rainwater from soaking in or infiltrating the soil. Some of the impacts of stormwater include flooding, sewer overflows, and nonpoint source pollution.
Stormwater is managed using storm sewers as well as stormwater controls, which include green infrastructure and low impact development.

2014 Stormwater Congress
New Orleans Morial Convention Center
September 27 - October 1
|Note: Proceedings from WEF events prior to 2011 are available to members at no cost on IngentaConnect. Proceedings from more recent events, including the 2013 Stormwater Congress and 2012 Stormwater Symposium, are available for sale at E-WEF.
Countries throughout the world have made strides in stormwater control, however the market remains underdeveloped – yet poised for major growth. World Water: Stormwater Management will cover this emerging global market. A quarterly international magazine by the Water Environment Federation Publishing UK Ltd. The magazine is dedicated to all topics stormwater, from research to policy to technology solutions. Subscribe to the print version or find complimentary copies online.
A workgroup dedicated to the investigation of a national stormwater testing and evaluation program. Learn more about the effort, and check out the white paper, "Investigation into the Feasibility of a National Testing and Evaluation Program for Stormwater Products and Practices."
WEF collected the videos on StormTV through the Stormwater Call for Media, an effort to share innovative stormwater projects through pictures and video. WEF does not endorse the services, products, or projects featured in the listed videos. Watch these and a growing list of videos on the stormwater playlist featured on the Water Environment Federation’s YouTube channel.
|User-Fee-Funded Stormwater Programs
|A must-read for agencies and public works departments interested in developing charge systems for stormwater programs based on fee structures.
|Design of Urban Stormwater Controls (MOP 23)
|Developed by WEF and ASCE, this MOP focuses on consolidating technologies under a comprehensive view of stormwater management in an attempt to foster a convergence between traditional stormwater controls and green infrastructure.
