Stormwater Management
What is stormwater runoff?
Stormwater runoff is water from rain or snow that does not soak directly into the ground. Instead, it flows from rooftops, across paved areas and sloped lawns. Different types of land cover produce different runoff rates and volume. Additional impervious surfaces result in increased runoff amounts.
What is the difference between stormwater and sanitary systems?
City storm sewers are separate from sanitary sewers and do not drain into municipal wastewater treatment facilities. They carry stormwater runoff from catch basins into streams, lakes and wetlands. The sanitary sewer is a system of underground pipes that carry sewage from bathrooms, sinks, kitchens and other plumbing components to the wastewater treatment plant where it is filtered, treated and discharged. Stormwater is not treated by the wastewater treatment facility.
