ABOUT THE METRO PLANT

The Metro Plant treats up to 65% of the wastewater generated in the Twin Cities region and is MCES's largest wastewater treatment plant. The Metro
Plant was constructed in 1938 and has incinerated solids for 80 years with an exceptional track record of environmental compliance. The existing
incinerator system, with three fluidized-bed incinerators, has been operational since 2005.

Hover over the images below to find out more about how much liquids and solids the Metro Plant processes.

The Metro Plant treats 180 Million GALLONS of wastewater every day for 66 communities

EQUIVALENT TO FILLING:

  • 1 US BANK STADIUM Every 3 days
  • 270 OLYMPIC SWIMMING POOLS Every day
  • 1.8 MILLION BATHTUBS Every day

The Metro Plant processes 850 WET TONS of solids every day for 73 communities

EQUIVALENT TO
THE WEIGHT OF:

  • 20 AIRPLANES Every day
  • 140 ELEPHANTS Every day
  • 420 MID-SIZE CARS Every day

Metro plant Location

The project is located at the Metro Plant, just southeast of downtown Saint Paul.
Solids from four other treatment plants are processed at the Metro Plant.

Metro Plant incinerator
Metro Plant is a model for sustainable
incineration in the wastewater community.

BENEFITS OF INCINERATION

Click below to learn more about the benefits of incineration of wastewater solids at the Metro Plant.

Air Pollution Control

The fourth incinerator will be designed with state-of-the-art air pollution control equipment that removes 99% of particulates, heavy metals, and other air pollutants. This graph compares emission data from the Metro Plant incinerators, represented as percentage of the corresponding federal standard for new incinerators.

Air Emissions Chart

Low Odor

Incineration technology at the Metro Plant has been a key factor in reducing odors from the Metro Plant. The graphic below demonstrates that incineration burns wastewater solids at 1,375 deg F which eliminates odor and disease causing bacteria.

Energy Recovery

The incineration energy recovery system recovers enough energy to power 2,400 homes. The energy recovered is used in the plant and saves ratepayers $2.5 million per year. The graphic below is a animation of the steam turbine generator at the Metro Plant.

Minimal Trucking

Incineration reduces the quantity of material to be hauled off-site for disposal by 95-percent. The graphic below shows how 850 tons of wastewater solids (75 trucks per day) are incinerated down to 40 tons of inert ash (2 trucks per day).
