- Stormwater Management
In accordance with the Pennsylvania Department of Environmental Protection’s (DEP) National Pollutant Discharge Elimination System (NPDES) General Permit regulations, Willistown Township is required to develop and implement a stormwater management program.
The program is based on the federal Municipal Separate Storm Sewer System (MS4) protocol (developed by DEP).
Best Management Practices
The DEP’s protocols provide our township with suitable guidelines to design a local program that addresses the DEP’s six Best Management Practices (or BMPs), which are also known as control measures.
These six BMP’s are designed to reduce the discharge of pollutants from MS4s, to the maximum extent practicable, to protect water quality, and to satisfy the appropriate requirements of the Federal Clean Water Act.
Best Management Practices Categories
The six BMP categories are:
- Construction Site Stormwater Runoff Control Measure
- Illicit Discharge Detection and Elimination Control Measure
- Pollution Prevention and Good Housekeeping for Municipal Operations and Maintenance Control Measure
- Post Construction Stormwater Management in New Development and Redevelopment Control Measure
- Public Education and Outreach Control Measure
- Public Participation and Involvement Control Measure
The federal regulations provide flexibility within these six categories of BMP’s.

Residents Can Help Too
Remember that goes into a storm sewer eventually drains into a stream. Please:
- Monitor storm sewer inlets near your property. No one should be dumping anything into the storm sewer system. Contact the Police Department at 610-647-1440 immediately if you witness illegal dumping.
- Clean up after your pets and dispose of their waste properly.
- Use fertilizers properly and efficiently to prevent excess runoff.
- Properly store materials that could contaminate water supply.
- Report any chemical spills.
