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.

is water that originates during precipitation events and snow/ice melt. Stormwater can soak into the soil (infiltrate), be held on the surface and evaporate, or runoff and end up in nearby streams, rivers, or other water bodies (surface water).

As an MS4, Yeadon 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

The Borough’s Annual Stormwater Report, as well as annual MS4 reports and other stormwater documents, can be viewed at Borough Hall.

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 911 if you witness anyone dumping materials into an inlet.

Builders: Don’t Let Stormwater Run Off With Your Money and Our Community!
The construction industry plays an important role in improving our community’s quality of life by protecting our streams and rivers
through smart business practices that prevent pollution from leaving construction sites. View this flyer to learn what you as a builder need to do.

As a Contractor performing work in our Borough, you can always make a difference in the condition of our local streams and waterways:

  1. Never allow chemicals, detergents construction materials or anything other than water to enter the Borough’s storm water system. For example, if you are doing concrete work, do not pour extra material into the street. These materials eventually enter our streams.
  2. Keep your worksite neat. Loose trash, gravel, or other building materials can find their way into the street and eventually be washed into the storm sewer system.
  3. Don’t allow your muddy vehicles to track dirt onto the streets.

Borough Code Officers will be inspecting your job to ensure that you are taking appropriate measures to prevent unwanted materials from entering our storm sewer system. Infractions can result in citations and fines.
