The new storm water separation project will save the city money by separating water upstream before entering the city's combined system.
The city, in turn, does not have to treat that waste water and it can enter the Missouri River.
Director of Public Works Jody Carlson says it will help them be more efficient..
"It's a good thing for the community in the fact that if we can get that creek water out of that system then that will allow us to treat more sewage that's within the system," he said.
The city is in the planning stages of building another waste water project at the Black Snake Creek.
Carlson says the city hopes to begin work on that sometime in 2015.
