After the Missouri Department of Natural Resources reclassified the effluent receiving stream in the city of Sullivan, officials learned that its wastewater treatment lagoon required a more advanced treatment process to comply.

The new infrastructure has provided cost-saving results for the ongoing removal of nitrogen and phosphorous.
