Stormwater Management

Stormwater runoff is generated when precipitation from rain and snow melt events flow over land and impervious surfaces and does not infiltrate into the ground. The runoff from streets, lawns, farms and construction and industrial sites pick up fertilizers, dirt, pesticides, oil, grease and many other pollutants and discharge into our lakes, streams and rivers. This untreated discharge is detrimental to our water quality as it can adversely affect our drinking water supply and environment. Many Best Management Practices (BMPs) such as detention/retention/infiltration basins are already in place to help keep our water clean.

Collegeville Borough regulates stormwater management which goes above and beyond typical BMPs through a permit that is obtained from the PA DEP - Stormwater Management (PA DEP) through the National Pollution and Discharge Elimination System Phase II (NPDES)/Municipals Separate Storm Sewer System (MS4). This is a federal requirement from the United States Environmental Protection Agency (USEPA) that is administered by the PA DEP. This NPDES Permit is broken up into six minimum control measures to be regulated and enforced by the Borough. These minimum control measures include:

 1.     Public Education and Outreach

 2.     Public Participation/Involvement

 3.     Illicit Discharge, Detection and Elimination

 4.     Construction Site Runoff Control

 5.     Post-Construction Runoff Control

 6.     Pollution Prevention/Good Housekeeping

 7.     How To Be Stormwater Smart

 8.     Backyard Environmental Education

 9.     Heathy Benefits of Green Infrastructure in Communities

10.    Protecting Water Quality from Urban Runoff

Collegeville Borough has begun monitoring and testing of storm sewer outfalls that have flow during dry periods. The Borough asks all residents to cooperate with the inspectors, asks some outfalls are located on private properties.

For any questions or concerns regarding stormwater or to report illicit discharges to the storm sewer system please call the Borough at 610-489-9208.
