Choctaw Ridge Wastewater Treatment Plant, Holts Summit, Missouri

Choctaw Ridge is a wastewater treatment plant located near US 54 in Holts Summit, Callaway County, Missouri. It serves a small population of approximately 70 people, reflecting its role as a local facility for a rural community. The plant operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal discharges to protect water quality. The plant provides secondary treatment, a standard level that removes biodegradable organic matter and suspended solids. With a designed capacity of 121.13 units and an actual discharge volume of 26.50 units, the facility operates well below its capacity, indicating room for future growth. The plant's permit is issued by the Missouri Department of Natural Resources under the National Pollutant Discharge Elimination System (NPDES), ensuring compliance with effluent limits. The treated effluent from Choctaw Ridge likely discharges into a local stream or river within the Missouri River basin, which ultimately flows into the Mississippi River and then the Gulf of Mexico. This downstream connection highlights the plant's role in protecting regional water quality and aquatic ecosystems in the central United States.

The plant's discharge enters a local waterway within the Missouri River watershed, which drains into the Mississippi River and eventually the Gulf of Mexico. This region supports diverse aquatic life, including fish and migratory birds, and the plant's secondary treatment helps reduce nutrient and pollutant loads that could contribute to hypoxia in the Gulf. The facility's inland location minimizes direct marine impact but still plays a role in the broader basin ecology.
