Coon Rapids Sewer Rehabilitation

This work will require tree removals, temporary closures of trails in Erlandson Park and Al Flynn Park, a temporary closure of the parking lot in Erlandson park, and brief driveway access interruptions.
 


 

The design of the project was completed in spring of 2022. In January 2023, crews began preparing the project area for construction. Construction will take place in two phases and is anticipated to be completed in by fall of 2023.





 

1. How long will the trails be closed near Erlandson Park and Al Flynn Park?
There will be multiple closures throughout the project. Most locations will close for two to three weeks at a time and one section of the trail near the Erlandson Park parking lot will close for up to 8 weeks. These closures are needed when crews install and remove the temporary conveyance pipes through the area, for CIPP lining, and when restoring the trails.

2. Will access to my home be impacted?
 If you live along the sewer pipe alignment areas, you may experience periodic, short-term driveway closures (see project map above. We will send out notifications in advance if driveway closures are needed.

3. What other impacts can I expect living near this project?
We do our best to mitigate noise and odors during construction, but residents will experience some noise, dust, and odors. There will also be pumps stationed along the temporary conveyance route that will run 24 hours a day to keep flow moving through the pipes.

4. How do I stay updated on this project?

Rehabilitation of the sewer pipes and structures will be done by inserting a liner into the existing pipes to form a new pipe or structure. Water is then used to extend and expand the liner, and then hot water or steam is added until the heat-activated resin in the liner hardens and forms a new pipe inside the existing pipe. This process is call Cured-In-Place Pipe (CIPP) and will extend the life of the pipes for several more years.


Crews are installing the CIPP liner into an existing pipe.

 

Above-ground temporary wastewater conveyance pipes will be installed to ensure that there are no disruptions to sewer service while crews rehabilitate the regional sanitary sewer system. These pipes will convey sewer flow around the work site during construction.
 
Some temporary conveyance pipes may be buried under driveways or roadways to maintain access/minimize disruption. Property owners will be notified in advance if this is necessary. Diesel pumps with noise dampening equipment (low noise) will run 24-hours a day, seven days a week as part of the temporary wastewater conveyance system.

MCES has developed three short videos to help explain why projects like this are necessary, what smells you may experience during the project, and how we will return the project sites to how they were before or better during the restoration phase.

“This Old Pipe”

The sewer pipes right under our feet are an important part of our wastewater infrastructure, but they are getting old and need repair. MCES has a strategic plan to fix aging sewer pipes to keep the region’s wastewater flowing and neighborhoods safe.

“What’s That Smell?”

As wastewater crews fix our pipes from the inside, you might smell - well, poop. Another smell you might notice is a little bit like glue. These smells are normal, and they can escape during repair. Our crews will monitor odors to meet air quality standards and we’ll do our best to reduce them during construction.

“Operation: Restoration”

MCES is committed to being a good neighbor and restoring our sewer construction sites back to how they were before, or better. We may need to remove or relocate trees and shrubs or wait for the right season to complete work like planting grass, but our on-site staff will be there to help!
