Illicit Discharge

City drains

The Drain is Just for Rain

The only thing that should be entering our City street drains, is rainwater! That’s because these drains go directly to our waterways.

Be an advocate for your water quality and water recreation activities! Be on the look out for any strage colors, smells, or materials getting into our drains or entering our waterbodies!

If you see anything suspicious, or have questions about something that might be harmful to our waters, call our Public Works Department at (763) 689-1800.
