Municipal Separate Storm Sewer System (MS4)

The Federal Clean Water Act of 1972 protects water resources

by providing policies to keep pollutants from the water supply

The Perkiomen Watershed began their work on the garden by installing a temporary deer fence and plantings in and around the basin.

What is MS4?

MS4 stands for “Municipal Separate Storm Sewer Systems” and is a network of grass swales, channels, underground pipes and other measures in the borough that collect and carry rainwater and snow melt off your property, onto streets and eventually back into our groundwater, streams and lakes.  Keeping stormwater runoff clean is a challenge because this water is easily contaminated from: Lawn Clippings & Chemicals (fertilizers, pesticides,etc.); Pet Waste; Oil and Grease from Vehicles; Sediment and Debris from Construction Activities; Improper Disposal of Trash​. All residents have a part in caring for our natural resources. By taking active measures to prevent water pollution at home and increasing cleanup efforts within our community, all residents can help protect the environment, wildlife and the quality of our drinking water.

Storm Water Quality - Red Hill Borough’s stormwater system is designed to collect storm water (rain and snow melt) and release it untreated, back into the Upper Perkiomen Creek Watershed. As rain and snow melt travel across our streets, parking lots and lawns, many pollutants can be collected and transported along the way. Typical stormwater pollutants include motor oil, lawn fertilizers, pesticides, trash and sediments. The Upper Perkiomen Creek Watershed is our source for drinking water, recreational activity and wildlife habitat. Red Hill Borough is committed to ensuring our stormwater system is efficient and properly maintained for the health of our residents and Watershed community. Red Hill is part of the Perkiomen Watershed - Visit the Perkiomen Watershed Conservancy Website
