Evaluation of MnDOT Wastewater Issues
The University of Minnesota Water Resource Center's Onsite Sewage Treatment Program and the Minnesota Department of Transportation (MnDOT) are performing a unique evaluation of the 52 existing subsurface sewage treatment systems (SSTS) at safety rest areas travel information centers, truck stations and weigh scales at MnDOT facilities across Minnesota. This six year partnership brings together the SSTS of the UM with the MnDOT wastewater unit’s agency and site knowledge. The goal of the project is to evaluate risk, provide a risk analysis ranking system, evaluate groundwater mounding and determine water usage per person.
