Storm Drain Marking Program

Everything that enters a storm drain flows directly to a nearby creek, stream or river. You can be the solution to water pollution by partnering with SD1 to place signage on some of Northern Kentucky’s more than 25,000 storm drains.

Why Mark Storm Drains?

Many people dump oil and other pollutants into these storm drains, unaware that they empty directly into nearby streams where fish and other wildlife live. Storm drain markers inform the public that only rain should go down the storm drain – not oil, unwanted paint, grass clippings or other waste.

SD1 hopes to mark all drains with messages such as, “No Dumping – Drains to Waterways” or “Only Rain Down the Storm Drain” to help alert people to the dangers of dumping substances or littering in curbside drains.

How You Can Get Involved


Gather a group from your neighborhood, school, scout troop, organization or business. Save-a-Stream is a community service project that all ages can find rewarding and fun, but please remember that all children must be supervised by a responsible adult. SD1 will provide your group with free storm drain marking supplies, including:

  • Markers
  • Adhesives
  • Wire brushes
  • Door hangers
  • Plastic gloves
  • Detailed instructions
  • A map showing the drain locations in the area you would like to mark
  • Safety vests
  • Additional supplies to aid in marking and cleanup

To participate, just complete the Storm Drain Marking Program Application.

Other Ways You Can Help

  • Don’t dump anything down storm drains
  • Keep grass clippings, leaves and litter away from curbside drains
  • Wash your car in the grass instead of the driveway
  • Use fertilizer and pesticide sparingly
  • Plant a rain garden and/or trees, shrubs and vegetation where you can
  • Pick up after your pets
