Municipal Separate Storm Sewer Systems (MS4) Program

Edgeworth Borough and Stormwater Management

Edgeworth Borough is gauging the public’s knowledge and understanding regarding stormwater management and runoff control. Please take the time and follow the link below to answer a short ten question survey. MS4 Survey

Nearly three decades ago, the United States Environmental Protection Agency (EPA) amended the Clean Water Act to create a two-part national program aimed at addressing stormwater runoff and its effect on water pollution. Phase I of that program was designed to address stormwater discharges from large cities across the country. Phase II was created to address stormwater discharges from smaller municipalities, like Edgeworth, and their Municipal Separate Storm Sewer Systems (MS4). Operators of MS4 systems in both cities and smaller towns are required to obtain certain permits from the federal government to cover the discharged stormwater they produce.

So, what is stormwater runoff?

Stormwater runoff occurs when precipitation from rain, snow, or melting ice flows over the land’s surface. When the water can be absorbed back into the ground, less amounts will run into rivers, lakes, and streams. But with more land development, the volume of runoff significantly increases. Constructing impervious surfaces, such as driveways and roofs, and neglecting to properly care for storm sewer pipes prevent the infiltration of water back into the soil. This leads to runoff being carried into bodies of water at a much higher volume, increasing the risk of flooding and soil erosion. Harmful chemicals and debris in the water also causes unsafe conditions for swimming, fishing, and aquatic life.

What can be done?

Effectively managing stormwater has a positive impact on the bodies of water we cherish. Even Edgeworth Borough and our residents play a role in protecting valuable resources, such as Little Sewickley Creek, from the dangers of water pollution. Edgeworth Borough maintains an extensive MS4 plan, full of best practices and management techniques, aimed at keeping stormwater runoff under control. However, residents making small changes to everyday habits help to produce lasting results. Here are some steps you can take to help combat water pollution.

  • NEVER dump any substance down a storm drain. Chemicals, pet waste, and even grass clippings contribute to pollution and will end up directly into a body of water. Dumping waste into a storm drain is also illegal.
  • Consider limiting the use of pesticides and chemical fertilizers throughout your property. Stormwater can pick up traces of these chemicals and place them in rivers and streams.
  • Consider planting a rain garden in low areas around the yard, and include native plants in gardens. Rain gardens help to collect storm water and infiltrate it back into the ground.
  • Use a rain barrel to catch rain water. Rain barrels collect stormwater, limiting the amount that has to runoff into storm sewers. You can use the collected water for gardens and to wash cars while keeping your water bills low!
  • Composting yard waste keeps debris out of storm drains, and becomes a great natural fertilizer in yards and gardens.
  • Always check vehicles for leaking oil or liquids. If left on the road or in a driveway, these substances can wash away with the rain and end up in a storm sewer.

By making a conscious effort to limit stormwater runoff, we can help create a cleaner, safer, and more sustainable community to live in.
