St. Croix Bluffs Regional Park: Hastings, MN

St Croix Bluffs Regional Park was adding a new shower facility, a new RV dump station, as well as the addition of sewered RV sites. Bedrock was found in the soil treatment area at 33”. The design flow for the proposed system was 4,678 GPD. The campground stayed open during the construction.


  • Gravity collection, septic tanks, and a lift station were installed to move effluent to the treatment area away from the camp sites.
  • Three Advantex ADX 100s with ultra violet disinfection were installed to reach treatment level A.
  • Jackhammers and rock breaking equipment were used to excavate for the large septic tanks used on the project.
  • Worked with Kraus Anderson and Washington County to meet construction deadlines while accommodating the guests at the campground.
