Wastewater Treatment Process

How It Works

Coon Rapids was served by a trickling filter sewer plant for many years. But by the early 1970's, the plant was judged to be overloaded and beyond repair.


The old plant, located on the far east end of town behind the Syngenta Seed Co. plant, was demolished in favor of a newer Facultative Lagoon System installed in 1977 east of Coon Rapids near Highway 141.

The cost of the lagoon system reached $660,000, of which 75% was funded by federal and state grants.
