Interesting Facts About Stormwater
Stormwater runoff is the leading cause of water pollution in Montana.
Missoula’s stormwater does not go to the Wastewater Treatment Plant.
Most of the City’s stormwater is discharged to our aquifer, via more than 6,000 dry wells, also known as sumps.
We have more than 60 miles of pipes that discharge stormwater to one of five water bodies; Clark Fork River, Bitterroot River, and Grant Creek do not meet water quality standards.
Our levees and floodwall protect more than $14 billion worth of property from potential flooding.
Together with other City and County programs, we work to keep our aquifer and waterways clean.
Runoff from Missoula properties and streets collect in stormwater inlets, flowing directly to our aquifer, rivers, and streams. This runoff can carry pollutants: oil from our cars, fertilizer from our gardens, animal waste, spilled chemicals, trash left on the ground, sediments, and anything else small enough to be picked up by stormwater. These pollutants affect our local industries and economies downstream. Together, we are working to reduce these pollutants and keep our rivers and streams safe and clean.
Worried there might be a polluting, illicit discharge in your neighborhood? You can either use the online form or call the general spill reporting number 406-258-4890.
