Overview of Stormwater
Stormwater is water that originates from precipitation, such as rain, snow or hail. It can cause pollution, flooding and other problems in urban areas, and can be treated with various methods, such as passive systems, to reduce its impacts.
The National Pollutant Discharge Elimination System (NPDES) stormwater program regulates some stormwater discharges from three potential sources: municipal separate storm sewer systems (MS4s), construction activities, and industrial activities.
Sources and Solutions
Stormwater picks up nutrients as it runs off lawns, streets and rooftops and carries them into waterbodies. This runoff is a major source of nutrient pollution.
Learn what stormwater is, how it affects water quality and quantity, and how it is managed by storm sewers and green infrastructure. Find out about WEF's stormwater initiatives, such as surveys, awards, and policy forum.

Polluted stormwater runoff can have many adverse effects on plants, fish, animals, and people. The primary method to control stormwater discharges is the use of structural and non-structural best management practices (BMPs). Most stormwater discharges are considered point sources and require coverage under an NPDES permit.
Urban development can have detrimental impacts on streams including altering hydrology, increasing nutrient, sediment, and pollutant loadings, and degrading biological integrity. Stormwater Best Management Practices (BMPs) can be used to mitigate the effects of urban development by retaining large volumes of stormwater runoff and treating runoff to remove pollutants. This project focuses on ...
Key Details About Stormwater
The U.S. Geological Survey is integrating its water science programs to better address the Nation's greatest water resource challenges. At the heart of this effort are plans to intensively study several Integrated Water Science (IWS) basins—medium-sized watersheds (10,000-20,000 square miles) and underlying aquifers—over the next decade. The IWS basins will represent a wide range of ...
The Stormwater Utility was created to help solve the problem of polluted stormwater and to improve the drainage capability of areas that are susceptible to flooding.
