Stormwater Management

Stormwater runoff is generated when precipitation from rain and snowmelt events flows over land or impervious surfaces and does not percolate into the ground. As the runoff flows over the land or impervious surfaces (paved streets, parking lots, and building rooftops), it accumulates debris, chemicals, sediment or other pollutants that could adversely affect water quality if the runoff is discharged untreated.

You can make a difference and help us keep our local waters clean. As a visitor to this site, you've already taken the first step: getting informed.

Step two: adopt a couple of clean water habits, such as:

Picking up after your pets and disposing of their waste properly
Applying fertilizer and pesticides in the proper amounts. Besides costing more, excess fertilizers just run off your lawn and into streams, where they cause nutrient-loading which in turn deprives aquatic species of proper oxygen levels
Maintaining your vehicle properly, and most importantly, not dumping oil or any type of fluid down storm drains
Washing your vehicle on grassed areas so that water with pollutants filter down through the ground and do not run directly into the storm drain system
Not littering, as litter often washes away along with storm water and can be ingested by fish, birds, or other wildlife.

What Residents Can Help Watch For:

Sediment leaving a construction site in stormwater
Spills (Chemical, Gas, Oil)
Illegal dumping activity into streams or storm sewers (PLEASE CALL 911 FIRST)
Dry weather flows from outfall pipes into streams (72 hours after a rain storm)

Residents may be the first to recognize "illicit" discharges dumping into storm sewers or coming out of from storm sewer outfalls. If you see an "illicit" discharge please report that to the township by one of the following methods:

Call the Township Office at (215) 257-5550
Send an e-mail to silverdale@silverdalepa.org
Call 911 after office hours
