Storm Water Pollution

The Missouri River is the source for drinking water for the City of Great Falls. It is important to keep our river water clean! All storm drain inlets go directly to the river. They are not tied to our sanitary sewer systems.

If you see or suspect a pollutant going into a storm drain that you feel could impact the storm water system and/or the Missouri or Sun rivers, please call 727-8390 between 8:00 am and 5:00 pm. After hours, call the Par-tner Hotline at 727-8637 or use the online form below. It is important that we are notified as soon as possible if there are pollutants going into our storm drains.
