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, is planning to replace and enlarge the aging regional sanitary sewer pipe and structures near Lake of the Isles and The Mall in south Minneapolis.

Improvements to the existing regional sanitary sewer system will be made along The Mall between Bde Maka Ska Pkwy East and Humboldt Avenue; and new sewer pipe will be installed along Humboldt Avenue between 27th Street and The Mall (see proposed project area map below). The existing sewer pipe that runs under Irving Avenue will be abandoned and removed at a future time.

To help minimize impacts to area residents, MCES will be working with the City of Minneapolis to upgrade the storm sewer pipe under Humboldt Avenue between 28th Street and The Mall. These improvements 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.

MCES is currently finalizing the design plans and estimates construction will begin in late summer/early fall of 2021. Construction activities will be completed in December 2022, but final restoration work may be completed in spring/summer 2023.


Proposed project area map

Map of proposed project area east of Lake of the Isles.  The Minneapolis storm sewer is located along Humboldt Avenue South for a short segment north of the Mall and south of West 28th Street.  The MCES sanitary sewer runs east from Bde Maka Ska Parkway East along the Mall, then north along Humboldt Avenue South to just past West 27th Street.
