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.
It all began back in the roaring 20s...
There are two systems that make up the wastewater facility for Coon Rapids. They are the collection system and the treatment system.
The wastewater collection system was constructed in the 1920's. This gravity flow system consisted of 6, 8, 10 and 12-inch vitrified clay pipe (vcp). Wastewater flowed to a trickling filter plant until 1978 when
a 3-cell facultative lagoon system was constructed.
As Coon Rapids grew over the years, so did the collection system. Extensions were built with "vcp" or plastic pipe for mains, ductile iron pipe or plastic force mains, two lift stations and numerous manholes. There are also several small, private pump stations.
Today the collection system consists of more than 348 thousand feet of mains, 160 manholes, 5 thousand feet of force mains and 2 lift stations.
Lift Station Improvement Project...
On January 30, 2008 the Board of Trustees approved an Engineering Services Agreement with Veenstra & Kimm, Inc., for Lift Station and Force Main Improvements...
