Stormwater Information

In effort to reduce stormwater pollution, and improve local water quality, Warwick Township must develop, implement, and enforce a Stormwater Management Program (SWMP). This task is required by the National Pollutant Discharge Elimination System (NPDES) permit, issued through the Pennsylvania Department of Environmental Protection (PA DEP) & the United States Environmental Protection Agency (US EPA).  The NPDES permit regulates stormwater discharges from the Township’s municipal separate storm sewer system (MS4): a series of inlets, pipes, swales, outfalls, and other drainage facilities that collect, convey, and discharge stormwater directly into our streams.

As part of the NPDES permit requirements, Warwick Township must implement best management practices (BMPs) in the six categories listed below and commonly referred to as minimum control measures (MCMs).

MCM 1: Public Education & Outreach
MCM 2: Public Participation & Involvement
MCM 3: Illicit Discharge Detection & Elimination
MCM 4: Construction Site Runoff Control
MCM 5: Post Construction Stormwater Management
MCM 6: Pollution Prevention & Good Housekeeping

Your Responsibility as a Homeowner in Warwick Township:

If you have a storm water management facility, such as a swale, basin, inlet, or outlet structure, most likely, you are responsible for maintenance of the facility. This could include simply mowing these areas and keeping them free from structures, to making sure the rip rap (dispersing rocks) is replaced as needed, that pipes are not clogged, or possibly replacing malfunctioning facilities.  Warwick Township staff inspects inlets and outfalls annually.  If a maintenance issue arises, a notice is mailed to the property owner identifying  the problem and providing recommendations to correct the issue.
