The Prairie Creek Treatment Train combines wetlands and water dosing to filter runoff from the watershed before it enters Grand Lake St. Marys. Water is lifted from Prairie Creek before it enters Grand Lake. The water is treated with Alum then released into former farmlands that have been repurposed as wetlands. The water settles in the wetland where it is naturally filtered prior to entering the open water of the lake.
