Project Description

Metropolitan Council Environmental Services (MCES), operator of the metro-area wastewater collection and treatment system, will be rehabilitating 8,000 feet of sanitary sewer pipes and structures in the City of Coon Rapids between Highway 10 and Coon Rapids Boulevard.

Due to the length of pipe being rehabilitated, work will be done in two phases, the North Phase and the South Phase. Crews will install aboveground temporary wastewater conveyance pipes throughout the project area to ensure there are no disruptions to service during construction.

Egret Boulevard Northwest is the dividing line between the north and south project phases.  The temporary conveyance route runs along the project area, mostly east of the project.

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 will be completed in spring of 2022. Construction is anticipated to begin in fall of 2022 and be completed in fall of 2023.

In fall of 2022, Metropolitan Council Environmental Services will host another public information meeting with the awarded contractor, who will provide a more specific construction schedule.


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?
 You can visit our project website for updated information, sign up for email updates on our project website, or contact us at any time by phone or email (see below).

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.

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.
