Lake Capri Lagoon Wastewater Treatment Plant, Boone County, Missouri

Lake Capri Lagoon is a wastewater treatment facility located in Boone County, Missouri, United States. It serves a small community of 125 people, operating as a lagoon-based secondary treatment system. The plant is situated inland, away from coastal influences, and plays a role in managing local wastewater in a rural or suburban setting. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater facilities. With a designed capacity of 79.49 volume units and a discharge volume of 49.21, it operates below its capacity. The facility is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Missouri Department of Natural Resources, ensuring compliance with federal and state water quality standards. The treated effluent from Lake Capri Lagoon discharges into local streams that eventually flow into the Missouri River, a major tributary of the Mississippi River. This contributes to the overall health of the Mississippi River Basin, supporting aquatic life and downstream water uses. The plant's operation helps protect local water bodies from untreated waste, maintaining ecological balance in the region.

The plant discharges into small streams within the Missouri River watershed, which ultimately drains into the Mississippi River and the Gulf of Mexico. This inland location supports a mix of agricultural and natural habitats, and the plant's secondary treatment helps reduce nutrient loads that could contribute to downstream eutrophication. The local watershed is part of a larger network that sustains diverse aquatic species and migratory birds.
