Shakopee Odor Project

MCES Project No. 809510

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.

Minnesota's response to COVID-19

The latest information on the state’s response can be found on the Minnesota Department of Health website.

Project Description

Metropolitan Council Environmental Services (MCES), operator of the metro-area wastewater collection and treatment system, is studying methods to reduce odor and corrosion associated with MCES sanitary sewer pipes that serve homes and businesses in the City of Shakopee, Minnesota.
 
MCES collects the City of Shakopee wastewater and conveys it to the MCES Blue Lake Wastewater Treatment Plant, where it cleans and discharges the treated water to the Minnesota River. Wastewater that leaves homes and businesses in the City of Shakopee ages as it travels through city and MCES sanitary sewers to the treatment plant. Biological and chemical reactions occur in “old” wastewater which can create odors. MCES is looking to improve the management of odor and corrosion in the MCES sanitary sewers that serve the Shakopee area.
 

Testing Information

 

Chemical Test

For a number of years, MCES has injected Calcium Nitrate into their regional sewers that pass through Shakopee to control odors and corrosion. MCES will be testing a different chemical in their regional sewers that may prove to be better at controlling odors and corrosion. The chemical they will test as part of this study is Magnesium Hydroxide.

Fan Test

MCES will conduct a fan test at 6100 County Road 101 East.  A fan will be placed over an MCES sewer maintenance hole at that location to determine how much odorous air can be extracted at that location and treated.

What to expect

While we do our best to minimize impacts during testing, some temporary inconveniences may occur as work takes place. These include:
  • Noise
  • Smell
 Odor and noise levels will be temporary and within safe levels for health.

 

What you can do

To help minimize odors in your home or business during chemical testing, please fill all drains with water to help keep odors in the sanitary sewer system. Drains include laundry sinks, floor drains, toilets, and more.

 

Project Schedule

Winter 2021-2022
  • Three weeks of in-sewer chemical pilot tests to monitor odor and corrosion reduction
  • Two days of sewer air extraction fan tests
Test dates will be updated as they are confirmed.
