Monitor Your Storm Drain

The storm drains for your street are grates built into the street, usually near the corner. These drains route rainwater and snowmelt runoff from impervious surfaces such as driveways, sidewalks, parking lots, and roads to the nearest stream, river, or Lake Superior. During heavy rain events, excess runoff can cause flooding and sewer overflows. Stormwater in the Duluth area is not treated at the treatment plant. Whatever is on the street ends up in Lake Superior. Keeping these drains open and free from pollutants is a job for everyone. 

How can an individuals and businesses help keep our storm drains clean and pollutant-free?

  • Use a rake or pitchfork to clear leaves, tree limbs and debris from on top of the grate.
  • Pick up grass clippings, leaves (compost them), dog waste, and litter from your yard and street.
  • Sweep up road sand in the spring.
  • Wash your vehicle on the lawn so soapy water will be absorbed into the ground and doesn’t flow into the storm drain.
  • Add rain barrels to your rain gutters to catch and save water for later use during dry weather.
  • Create a rain garden
