WWTP Expansion

The Wastewater Treatment Plant (WWTP) looks quite a bit different than it did a month ago with the new Fine Screen Building standing tall between the Main Lift Station and Administration buildings. The precast walls were placed in about a week’s time in early December and the brick façade blends in nicely with the existing structures. 

Work is continuing within the structure and the three fine screens are expected to be installed in January. Concrete work continues at the membrane bioreactor (MBR) building even through the winter conditions. The temporary earth retention system which supports existing structures has been installed so excavation and foundation work can be completed at the Solids Thickening Building.  

There has been a lot of discussions and planning completed for the months to come as the construction work will start to have a greater impact on wastewater process. The contractor is working with the plant operators and the engineer to sequence construction activities to ensure the WWTP continually meets its effluent permit limits as existing processes are being modified.

City of Owatonna & Steele County Joint Construction Projects:

  • Bixby Road/18th Street Roundabout: The project will construct a roundabout at the intersection, currently controlled by side street stop signs. The Owatonna school district has proposed building a new high school east of this intersection and had a School Traffic Impact Study completed to identify impacts associated with the proposed development. The study identified significant operational and safety issues associated with the increase in traffic volume expected at the intersection. The expected traffic volume increase would lead to unacceptable traffic delays with the existing infrastructure. Also, given the high speeds along CSAH 48, skewed roadway geometrics, and adjacent railroad crossing, any increase in traffic volume could pose a potential safety risk. The study recommended the best alternative to address these issues is to construct a roundabout before the proposed high school opens in Fall 2023.

  • 29th Avenue (East Side Corridor): The project will construct a new north-south route on the east side of the City of Owatonna from near the US 218/18th Street SE intersection to CSAH 34 (26th Street NW).  Traffic currently has no direct route for traveling between the northeast part and the southeast part of Owatonna.  All existing highways and streets direct traffic towards the downtown area adding unnecessary traffic in the downtown area and increasing travel times.  In 1999-2000, Steele County and the City of Owatonna recorded an Official Map of a future north-south road from 26th Street to US 14, calling it the East Side Corridor. In 2005, the County recorded an Official Map of the Owatonna Beltline, consisting in part of CSAH 43 to the east. While CSAH 43 will have connections to US 14 and will provide a north-south connection for future growth, it does not provide benefits for current needs of traffic on the east side of the City, especially with the relocation of the high school near the intersection of CSAH 48 and 18th Street NW.

    • Project Schedule:
      • 2022-2023 Environmental Study and Preliminary Design in progress    
      • 2024 Final Design & right of way acquisition
      • 2025-2027 Construction in stages
  • Main Street (Oak to Chambers): Steele County together with the City of Owatonna is conducting a feasibility study along Main Street from Oak Avenue to Chambers Avenue. A feasibility study looks at the existing conditions of a roadway and determines the best way to improve it. This study will include a thorough review of the corridor's pavement conditions; identification of opportunities of walking, biking, and rolling; and a traffic analysis of the entire study corridor.
