Bevier WWTP - Secondary Wastewater Treatment Plant in Bevier, Missouri

Bevier WWTP is a municipal wastewater treatment plant located on Heritage Road in Bevier, Macon County, Missouri. The facility serves a population of approximately 718 residents, classifying it as a small community wastewater system in the rural Midwest. 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 378.54 megaliters per year and an average discharge volume of 113.56 megaliters per year, the plant operates well below its capacity, indicating room for future growth or seasonal flow variations. Treated effluent from the plant is discharged into local streams that ultimately drain into the Mississippi River basin. The facility plays a key role in protecting local water quality and downstream ecosystems, including the Missouri River and the Gulf of Mexico, by reducing nutrient and pathogen loads from the community's wastewater.

The plant's discharge enters small tributaries within the Upper Mississippi River basin, which flow into the Missouri River and eventually the Gulf of Mexico. This region is part of the Mississippi River watershed, which supports diverse aquatic life and is a critical migratory corridor for birds and fish. The plant's secondary treatment helps reduce nutrient pollution that contributes to the Gulf of Mexico hypoxic zone.
