Stormwater Management
  • Program
The Clean Water Act is the federal legislation that governs stormwater management. Stormwater point discharges to waters of the U.S. are regulated using National Pollutant Discharge Elimination System (NPDES) permits. In 1999, federal regulations extended coverage of the NPDES program to local separate storm sewer systems (MS4’s) serving populations less than 100,000. Upper Uwchlan Township is required to comply with the NPDES program as an MS4. Under the NPDES stormwater program, permittees must develop a stormwater management plan that provides the details of how the community will comply with the requirements of the permit. Permits are based on a framework of six minimum control measures: 
  • Public education and outreach
  • Public participation and involvement
  • Illicit discharge detection and elimination
  • Construction site runoff control
  • Post-construction storm water management in new development and redevelopment
  • Pollution prevention and good housekeeping for municipal operations and maintenance

Upper Uwchlan Township's Municipal Separate Storm Sewer System (MS4)
Upper Uwchlan Township is a participant in and is complying with all the requirements of the Pennsylvania Department of Environmental Protection's (DEP) Municipal Separate Storm Sewer System (MS4) program. The goals of the MS4 program and Upper Uwchlan Township are to reduce the discharge of pollutants from the Township, to protect water quality, and to satisfy requirements of the Clean Water Act. Please remember that the water, and any items that go into a storm sewer, goes directly into local streams. This water is not cleaned in any way and does not go to the waste water treatment plant. Residents can assist in keeping our stormwater and stormwater system clean by doing the following: dispose of water properly, clean up after your pets, use fertilizers properly and efficiently to prevent excess runoff, and store potential pollutants indoors. Please monitor stormwater inlets near your property. No one should dump anything into the storm sewer system. If you see someone dumping please call the township at 610-458-9400.
