There hasn't been a lot of rain this year so city leaders can't say for sure how much upgrades to an old sanitary sewer system is helping.
"Those are the types of things that will really show us the true test on our system whether we've picked the right spots, whether we've made the improvements that really are going to help us in the long run," city engineer Robin Bobzien said.
Somehow, water from the storm sewer is getting into the sanitary sewer and overwhelming it during wet years. When it can't keep up, the city has had to release sewage into Moccasin Creek.
It could also cause sewer back-up in homes. Margaret Wild hasn't had that happen yet. She lives near a street where the city is replacing sewer pipe and is thankful to the progress.
"Work needs to be done from time to time. The sewer pipes and storm sewers and all those things don't last forever. So they need to be fixed," Wild said.
The city started replacing pipe last year in a part of town it believes the most damaged pipe exists. And it's working out from there.
The city is spending $1.5 million to $2 million dollars on this project each year and it'll be going on for a while.
"I would anticipate five to six years yet of this type of work before we're really feeling that we have most of the problem areas addressed," Bobzien said.
And the city expects a sewer system working better each year more pipe replacements are done. City leaders are hopeful there are already noticeable improvements even without a heavy downpour to prove it.
