Project Overview

Metropolitan Council Environmental Services (Met Council), operator of the metro-area wastewater collection and treatment system, plans to remove and replace the aging sanitary sewer pipe in the Bossen Field area of South Minneapolis. This project will be completed in two phases.

Phase 1 - Completed May 2026

In this project, an aging sanitary sewer pipe was rehabilitated with Cured-In-Place Pipe (CIPP). The project followed 58th Street, through Bossen Field Park, and ended on 30th Avenue. This phase of the project included approximately 1,800 feet of CIPP and restoration of seven maintenance holes. To learn more about CIPP in the “Cured-In-Place Pipe Lining Process” section below.

Aboveground temporary wastewater conveyance pipes were installed at select locations to ensure there were no disruptions to the sanitary sewer service during construction. To learn more about this, check out the “What is a Temporary Conveyance System” section below. The temporary conveyance was placed on the west side of the park along the trees. Access in and out of the park on the west side was limited to current paved trails.

Much of the heavy construction started in the fall of 2025 and finished in May of 2026. Most restoration work was completed in the spring of 2026, with crews continuing final seeding and watering activities.

Phase 2 - Upcoming

Following Phase 1 work, aging sanitary pipe under 29th Avenue South between 53rd and 56th Street East will be removed and replaced. The project will occur within the 29th Avenue right-of-way and consist of road removal; replacement of the Met Council sewer; replacement of the gas main and City of Minneapolis water main, sanitary sewer, and storm sewer; and road restoration.

Temporary conveyance pumps and pipes will be set up to transfer wastewater around the construction area. These pipes will be located on the sidewalk on the east side of 29th Avenue between Bossen Field Park and 53rd Street. They will be buried under road crossings. You can learn more about this in the “What is a Temporary Conveyance System” section below.

Scheduling for Phase 2 is still to be determined, but that information and potential impacts will be shared in advance of construction. Impacted landowners will received direct communication prior to any Phase 2 construction activities.

What to expect

While we do what we can to minimize impacts during construction, some temporary inconveniences may occur as the work takes place. Here is what you can expect:

Noise, vibration, dust, and odors related to sewer work
Project equipment staged in Bossen Field Park
Heavy equipment in the neighborhood including cranes, excavators, and dump trucks
Temporary road closures. Alley access is expected to be maintained for all residents throughout construction.
Temporary sidewalk closures
Tree trimming and removal
Vegetation disruptions
Temporary utility disruptions anticipated during weekday business hours. Advance notice will be provided.
Bossen Field Park will remain open. One baseball field will be closed during the off-season to accommodate the construction staging area .
Restoration of any disturbed road surface, sidewalk, and landscaping after construction is complete.

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 called 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

Aboveground temporary wastewater conveyance pipes are installed to ensure there are not disruptions to the sanitary sewer service during construction. These pipes 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 conveyance system.

Example of aboveground temporary wastewater conveyance pipes. Sometimes pipes are buried under intersections and driveways to maintain access during sewer work.

Metropolitan Council Environmental Services has developed short videos to help explain why projects like this are necessary and how we will return the project sites to how they were before or better during the restoration phase.

Operation: Pipe Repair

The sewer pipes right under our feet are an important part of our wastewater infrastructure and need repair. Environmental Services has a strategic plan to fix our pipes to keep the region’s wastewater flowing and neighborhoods safe.

“Operation: Restoration”

Metropolitan Council Environmental Services 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!

“What’s That Smell: Sewer Repair”

We work hard to be good neighbors, including keeping our noise, dust, and… well, smell… to a minimum. But sometimes you might smell something near one of our construction projects, and that’s pretty normal. Be sure to fill your drain pipe with water to keep sewer smells from coming into your house. And contact us if you are ever concerned about a smell.
