In 2017, the City was awarded $19,500,000 in USDA Rural Development grants and loans to design and construct improvements to the wastewater collection and treatment system. Phase 1, which included improvements to the City’s wastewater treatment plant, was constructed between 2020 and 2022. Phase 2, which included the replacement of the City’s highest volume gravity sewer main, was constructed in 2020. Now, the project has reached Phase 3, which is the improvement of over 11,000 feet of sewer main throughout the City.

The project area extends throughout the residential area and downtown commercial core. The following streets are a summary of the project area. For more information, please see the figure linked below:

Frequently Asked Questions:

 

Where is this project located?
Work will take place throughout the City. More information can be found in the Project Area Exhibit linked above.

 

What are the purposes of this project?
The goal of this project is to rehabilitate the most critical pipes in the City's wastewater collection system. This will be done by lining the existing sewer pipes with a cured-in-place pipe. This essentially creates a new plastic pipe within the existing pipe without requiring excavation.

 

I live, work, or own a building in the project area . How will this impact me?
While the contractor is working on the section of sewer main that your house or business is connected to, you will be asked to not discharge any wastewater. This includes activities like flushing a toilet, using a shower, and running a dishwasher. We anticipate that this will last a maximum of one business day between the hours of 7am and 6pm. You will receive more detailed notifications before this work is to take place.

 

How will this project impact traveling through the residential area of the City?
The majority of the work will be completed with relatively minor traffic impacts. Within the residential area, please expect a single lane closure or a shoulder closure. Traffic delays due to the project should be less than 5 minutes long.

 

How will this project impact deliveries to the downtown commercial core of the City?
Please note that this work has been delayed due to material procurement. The pipe lining work in Edelweiss Weg will be rescheduled at a future date and time to minimize the impact to business operation. During the days that work is taking place on Edelweiss Weg, the downtown alley that is located between Front Street and Commercial Street, delivery vehicles will not be able to access the alley between the hours of 7am and 6pm Monday through Friday. It will be each business' responsibility to coordinate this with their delivery vehicles. We anticipate this impact will be a maximum of two weeks.
