Project Overview

Metropolitan Council Environmental Services (MCES), operator of the metro-area wastewater collection and treatment system, made improvements to aging and deteriorating regional sanitary sewer facilities that serve businesses and homes in Brooklyn Park, Osseo, and Maple Grove.

MCES routinely inspects regional sanitary sewer pipes and rates them on the scale of 0 to 5. Improvements in this area were necessary because the pipe was rated condition 5, which is very poor and in need of immediate repair. In 2018 and May 2022, sections of the regional sanitary sewer pipe in this area failed, requiring repair under an emergency declaration. This project rehabilitated the remaining pipe and maintenance holes in the area.  


The project site is located in Brooklyn Park and Osseo on 85th Avenue between Jefferson Highway and Bottineau Boulevard (cured-in-place pipe construction) and County Road 81 between 85th Avenue and 3rd Street SE (excavation construction). The construction staging area is located between 83rd Avenue N and USI-169 on the west side of USI-169. Temporary wastewater conveyance pipes run along both portions of the project.  

Project Schedule

Project design occurred 2019-2021, construction is in 2022, and restoration is expected in spring 2023

What to Expect

While we do our best to minimize impacts during construction, some temporary inconveniences may occur as the work takes place, including noise, vibration, lights, and odors related to sewer work. Some work will occur overnight.

Traffic impacts will include short-term road closures with designated detours and single lane closures.

What You Can Do

To help minimize odors in your home or business during testing, please fill all basement drains with water to help keep odors in the sanitary sewer system. Drains include laundry sinks, floor drains, toilets, and more.

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!
