CTS Webinar: Evaluating Options for Wastewater Treatment at Rest Areas and Truck Stations
About the Webinar
The Minnesota Department of Transportation (MnDOT) is responsible for 52 safety rest areas and truck stations across Minnesota that are served by subsurface sewage treatment systems (SSTS). Managing these SSTS is an important activity, and a better understanding of the functionality and treatment of these systems is critical for the agency.
This webinar highlighted a U of M research project that aimed to better understand the treatment occurring in SSTS and the impacts of wastewater on groundwater systems, soil, and vegetation. The study included evaluations of groundwater mounding, septic tank performance, and related waste streams (such as wash-down water from salt trucks).
Attendees also learned about current and future applications of wastewater treatment from MnDOT.
The webinar was held in conjunction with a CTS Environment and Energy in Transportation Research Council meeting.
