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.
