Metropolitan Wastewater Treatment Plant (WWTP) Solids Renewal and Improvements

MCES Projects 805947 and 808920

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.

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

The primary driver of the project is to ensure reliability of existing solids processing facilities until the fourth incinerator is operational in 2026. The project scope items were selected to preserve existing wastewater treatment infrastructure and optimize and improve performance. 

The project is located at the Metropolitan Wastewater Treatment Plant (Metro Plant).  The Metro Plant treats 180 million gallons of wastewater and 850 wet tons of wastewater solids every day.

This project includes renewal and improvements of three sewage sludge incinerators and associated energy recovery and air pollution control equipment including miscellaneous equipment related to processing wastewater solids. More information about the project can be found on the project brochure located here:

Project Schedule

The solids renewal & improvements project is part of a larger program to increase solids processing capacity at the Metro Plant. This first renewal and  improvements project will perform immediate work needed during shorter eight-week incinerator shutdowns.

The fourth incinerator will then be constructed from 2024-2026. The added capacity from the fourth incinerator will allow for more extensive renewal to occur on the existing incinerators from 2027-2029 as the existing incinerators will be 20 years old and will need to be taken out of service for six months to one year at a time.

Metro Solids Renewal project timeline.  2020 to 2024 is the renewal and improvements project at $20 million.  2024 to 2027 is the Fourth Incinerator project at $150 million.  2027 to 2030 is the renewal project at $30 million.
