East Isles Sewer Improvements Project

MCES Project No. 804125

Understandably, the spread of COVID-19, also known as the coronavirus, has raised questions about the status of Metropolitan Council Environmental Services (MCES) plant and interceptor construction projects. Please note the following:

  • Construction on wastewater treatment plants and sewer interceptors will continue. The contractors are following working environment protocols (asking employees to stay home if they are sick, social distancing, etc.) as outlined by public health agencies.

  • Some project staff are working remotely while others remain on-site to ensure proper oversight of the project. Staff will stay connected through emails, conference calls, and web-based meetings to manage construction activities.

Contact information

For information regarding construction, please call the construction hotline or send an email to the contact information listed on the bottom of that project’s website.

While the response to COVID-19 continues to evolve, we will continue to monitor and review construction activities and conditions through our field inspectors and their on-site reporting.

We will be using electronic communication methods to share information, should there be additional updates. Subscribe to updates by text or email.

Project Description

Metropolitan Council Environmental Services (MCES), operator of the metro area wastewater collection and treatment system, will replace and enlarge the aging regional sanitary sewer pipe and structures near Lake of the Isles. Improvements to the regional sanitary sewer system will be completed in coordination with the City of Minneapolis’ utility work along Humboldt Avenue and the Minneapolis Park and Recreation Board’s (MPRB) Southwest Service Area Master Plan along The Mall to minimize impacts to area residents.

Humboldt Avenue 2022
Two new sewer pipes will be installed under Humboldt Avenue between The Mall and 27th Street, and we will replace and install new sanitary sewer structures under the intersection of Humboldt and 27th Avenues. The existing sewer pipe that runs under Irving Avenue will be abandoned and removed at a future time.

The city will be upgrading their storm sewer and replacing a portion of their watermain and sanitary sewer pipes and structures under Humboldt Avenue between The Mall and 28th Street. The improvements to the storm are being made to increase water flow capacity and to reduce the probability of flooding on Humboldt Avenue. The City of Minneapolis will be extending the stormwater pipe along The Mall between the MCES project and Lake of the Isles at a later time.

The Mall and Woonerf Plaza (tentatively 2023)
The existing sewer pipes along The Mall and Bde Maka Ska Parkway E and Humboldt Avenue will be replaced with new and larger pipes. We will be working with the MPRB to replace The Mall road east of Humboldt Avenue with brick pavers as part of the new Woonerf Plaza that will be installed between Humboldt Avenue and Hennepin Avenue. This work is tentatively scheduled to begin spring 2023 and completed in winter 2023 with final restoration activities completed the following spring/summer.

Construction activities for Humboldt Avenue between The Mall and 27th Street will begin March 2022 and be completed in fall 2022. Final restoration work may be completed in spring/summer 2023. Construction along The Mall and Woonerf Plaza is tentatively scheduled to begin spring 2023 and completed by December 2023 with final restoration activities completed the following spring.

Timeline showing construction activities will occur spring to fall 2022 and final restoration activities will occur spring to summer 2023.
