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
Warwick Township in conjunction with PA Department of Environmental Protection is making the brochure "When it Rains, It Drains" available for download on its website. This brochure explains stormwater runoff, and what you can do to improve the water quality in our area.
