St. Croix Valley Wastewater Treatment Plant Restoration Project

MCES Project No. 070227

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.

About the project

This project will restore facilities at the St. Croix Valley Wastewater Treatment Plant in Oak Park Heights that were damaged by a fire in 2018. Temporary repairs were made shortly after the fire to keep the treatment plant fully operating. This work will provide permanent restoration to the facilities.

The St. Croix Valley Plant treats wastewater for the cities of Oak Park Heights, Stillwater and Bayport. The plant treats approximately 3 million gallons of wastewater daily and discharges the resulting clean water to the St. Croix River. The plant is located northeast of the intersection of Highway 36 and Highway 95, just south of the Sunnyside Condominiums.

The restoration project will focus on the plant’s odor control building and most of the work will occur inside that building. Major components of the work are:

  • Cleaning and coating of floors, walls and ceilings.
  • Replacing the following systems: HVAC, odor control, lighting, fire alarm, and sump pump.
  • Repairing plumbing and restrooms.
  • Modifying the electrical system.

Construction will take place from March 2020 to approximately June 2022.

There should be minimal impacts to public, other than a small increase in daily traffic to and from the St. Croix Valley Plant via 59th Street North. The plant will continue operating throughout the restoration project and there will be no impact on sewer service in your community.
