Storm water is water that flows across the land and is routed into drainage systems and ultimately into our natural areas such as creeks, lakes, and wetlands. Storm water is not limited to precipitation but may also come from watering the lawn, washing the car, and many other sources. Unlike sewage, storm water is not treated before it enters our waterways. In some cases, it is filtered by traps or wetlands, usually located at the end of pipe systems, but in most cases, it flows directly from our streets and gutters into our creeks, rivers, and lakes. The preservation of our waterways is important to present and future generations. Despite increasing populations and levels of development many of our streams still retain significant natural value and provide important environmental, commercial, and recreational benefits. It is important that these uses are protected from the threat of storm water pollution.

What can you do to help protect our storm water system? 

We all play an important role when it comes to protecting our water resources. Here are a few things you can do in and around your home to keep pollution out of our storm water system.

  • Use a rain barrel to collect water for your garden. Rain barrels reduce runoff and ease the load on our water treatment plants.
  • Wash your car at a carwash, rather than in your driveway, to prevent soapy water and sediment from entering our storm water system.
  • Sweep dirt from your sidewalk and driveways and put it in the garbage, instead of on the road.
  • Pick up pet waste regularly.
  • Ensure your downspouts drain onto your lawn or garden areas, not directly onto streets or alleys.
