Stormwater Management

Stormwater management is, regulated by the Clean Water Act and by the Borough’s National Pollutant Discharge Elimination System (NPDES) permits. The NPDES program includes local separate storm sewer systems (MS4s) that serve populations with fewer than 100,000 residents.

Information Pamphlets are available at: http://cfpub.epa.gov/npdes/stormwatermonth.cfm

More information about the MS4 program is available from the Pennsylvania DEP website. www.depweb.state.pa.us/watershedmgmt

As an MS4, West Conshohocken Borough is required to develop a stormwater management plan that involves the community through:

  • 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

The goals of stormwater management are to:

  • Reduce the discharge of pollutants
  • Protect water quality
  • Satisfy requirements of the Clean Water Act

Anything that goes into a storm sewer goes directly to streams, without being cleaned or filtered at a treatment plant. Residents can help by being careful about using materials that could end up in the stormwater system and by monitoring storm water inlets. Items that can run off into storm drains and cause pollution include:

  • Pet waste
  • Fertilizers
  • Sediment from construction sites
  • Chemical, gas and oil spills

Dumping into the storm sewer system is illegal and dangerous! Call the Borough Code Office at (610) 838-9747 ext 3 during business hours if you witness anyone dumping materials into an inlet. Call the Police Department at (610) 940-5842 if you see illicit dumping after hours or on weekends.
