Dent’s waste stabilization pond system was aged and failing. Wastewater seepage from the ponds into the ground water exceeded the Minnesota Pollution Control Agency’s requirements. Plus, the system was located in the heart of Minnesota lakes country, making discharges of sewage all the more subject to environmental scrutiny.
To solve the seepage problem, Moore Engineering designed a containment system that utilized a synthetic liner. Rapid Infiltration Basins (RIB) were designed to reduce the environmental effects by providing controlled disposal of the treated wastewater into the subsurface of the surrounding site.
Excessive seepage from the pond system has been eliminated and sampling of the ground water revealed the RIBs are properly disposing of the treated wastewater.
