METRO PLANT SOLIDS MANAGEMENT improvements FACILITY PLAN

Metropolitan Council Environmental Services proposes to continue sustainable incineration at its Metropolitan Wastewater Treatment Plant (Metro Plant) in St Paul.

More information about the project can be found in the project overview brochure below.

 
Incineration process at Metro Plant

PROJECT NEED

The Metro Plant needs additional solids processing capacity to:

Preserve existing wastewater treatment plant infrastructure


Planned renewal projects will require extended downtime of the existing incinerators.

Serve regional population growth


500,000 new residents in the Twin Cities Metro Plant service area by 2050.

PROJECT BENEFITS

The fourth incinerator is the most cost effective and sustainable alternative to meet the region’s wastewater needs.

 
 

It will have the lowest community impact and will improve the reliability of the wastewater treatment system.


EXCEPTIONAL AIR QUALITY

The fourth incinerator will meet strict air emission standards, ensuring protection of human health and the environment.
 


LOW IMPACT

A fourth incinerator will not generate additional odors or require land acquisition, providing the lowest impact to surrounding communities.
 


ENERGY RECOVERY

Incineration recovers enough energy to power 2,400 homes. The energy recovered is used in the plant and saves ratepayers $2.5 million per year.
 


COST EFFECTIVE

Adding a fourth incinerator costs 50% less to construct, operate and maintain than any other solids processing alternative.


LOW GREENHOUSE GASES

Greenhouse gas emissions are similar to other alternatives, insignificant compared to other industries and are offset through energy recovery.


SYSTEM RELIABILITY

The fourth incinerator will allow the Metro Plant to serve as backup to other MCES facilities, increasing reliability of the whole MCES system.

PROJECT SCHEDULE

Design and permitting is expected to be completed by the end of 2021. Construction is anticipated to be completed by the end of 2024. Outreach to the public will occur over the life of the project.
