Report a Concern
To report a concern (sinkholes, erosion, debris in inlets, etc.) please call the Stormwater Hotline at 215-348-9915.
Stormwater management concerns the control of water (from rain, melting ice or snow) that runs off the surface of the land. The amount and rate of runoff is increased as land is developed; construction of impervious surface (e.g. parking lots) hinders the infiltration of rainfall into the soil.
Therefore stormwater management is imperative to offset the possible impacts of development – flooding and erosion problems, concentration of flow on neighboring properties, damages to infrastructure, and non-point source pollution (i.e. pollution that comes from the general drainage of the land such as runoff from parking lots and farmland).
New federal National Pollution Discharge Elimination System (NPDES) regulations require municipalities in urbanized areas to obtain permits, as well as implement and enforce a DEP approved stormwater management program with the goal of protecting water quality. This program must contain a schedule, best management practices, and measurable goals for the following: public education and outreach, public participation and involvement, illicit discharge detection and elimination, construction site runoff control, post-construction stormwater management in new development and redevelopment, and pollution prevention and good housekeeping for municipal operations and maintenance.
For more information about the stormwater management program, visit www.dep.state.pa.us; type “stormwater” in the directLINK input filed in the upper left-hand corner of the screen.

Help keep our waterways and drinking supplies clean. Be aware of common pollutants and their impacts. Common pollutants consist of herbicides, pet waste, automotive fluids, grass clippings, and other debris that enter storm water systems and ultimately end up ion our water ways. Please practice good household habits for the health of our environment.
