Stormwater is water from precipitation that comes in many different forms including rain, sleet, snow and ice.  The goal of Stormwater Management is to control this precipitation to the fullest extent possible.  Construction of new impervious surfaces, such as homes, driveways, sheds, parking lots, etc.  add additional water to the storm sewer system as well as pollutants.

Through the Municipality’s Stormwater Ordinance and the implementation of the Municipal Separate Storm Sewer System (MS4) permit, Bethel Park seeks to control water at the source in order to mitigate flooding and improve the quality of the stormwater entering the creeks and streams.

Additional information on the Municipality’s MS4 Permit and the National Stormwater Program is available online at
