Melting snow has inadvertently led to raw sewage flowing into the Spokane River at eight different locations.
There's no word yet on how much untreated sewage has flowed into the river.
Water from storm drains and sewage is normally treated at Spokane's wastewater treatment plant, but during rain on snow events or big thunderstorms, sewer pipes can't handle the volume and some of it ends up in the river.
"Yeah, it's a little alarming when your first see and you're thinking whoa, somebody made a mistake, this isn't supposed to be here and then I found out it was supposed to be here it because that's just the way it's been done," Peaceful Valley resident Aaron Steiner said.
In all there are 20 spots along the river where sewage overflows can happen and signs warn people of the possible contamination.
For several years now the City of Spokane has been building underground vaults, like one on the South Hill currently under construction on Ray Street between 17th and 29th avenues. These vaults are designed to store surges or runoff until the weather conditions improve.
