Deep Sewer Tunnel Cleaning Project

MCES Project No. 807642

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.

Project Description

During 2019 and 2020, the Metropolitan Council Environmental Services (MCES) will be cleaning several large diameter sanitary sewer interceptors located in Minneapolis and Saint Paul.

Cleaning activities will include inspecting the pipes with televising and/or sonar equipment to confirm locations and quantities of debris to be removed; cleaning of pipes using high velocity water jetting equipment and/or vacuum trucks; drying of debris; and disposal of debris at licensed landfill.

Jetting and debris removal will be conducted through existing access structures with minimal surface disruption and pavement restoration. Work will be conducted within the existing rights-of-way to minimize traffic disruption.
