Cities, counties, and other public entities commonly utilize municipal separate storm sewer systems (MS4) to collect and convey stormwater runoff in sewer drainage systems that are separate from sanitary sewer systems. Water flowing through the sanitary sewer system goes to treatment facilities where it is cleaned before discharging to waterbodies. However, water flowing through MS4s usually drain directly to waterways without being treated. In order to protect and prevent harmful urban pollutants from entering waterbodies, municipalities of certain sizes must obtain MS4 permits and regulate the discharge of stormwater. Existing infrastructure no longer supports current stormwater management needs in many places. The life of current stormwater management systems can be extended through the implementation of low impact development practices.
