Storm Drain Marking

Storm drain marking helps increase awareness of the storm drain’s connection to our local water resources. Educate your community about stormwater pollution by marking storm drains with “No Dumping, Drains to Lakes” (or river or stream) and distribute informative door hangers.

By participating in this activity, your group will:

  • Learn about stormwater pollution,
  • Understand why stormwater pollution is a threat to the environment, and
  • Increase awareness of stormwater by marking storm drains.
