LINNEUS WWTP - Linneus, Missouri Wastewater Treatment Plant

LINNEUS WWTP is a municipal wastewater treatment facility located in Linneus, Linn County, Missouri. Serving a small population of 278, the plant provides secondary treatment, which is the standard for small communities in the United States under the Clean Water Act. The plant has a designed capacity of 227.12 thousand cubic meters per year and discharges 132.49 thousand cubic meters annually. As a US facility, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. The treated effluent is discharged into local waterways that drain into the Mississippi River basin, ultimately reaching the Gulf of Mexico. The plant plays a role in maintaining water quality in the region's streams and rivers, supporting aquatic life and downstream ecosystems.

The plant discharges into the Mississippi River basin, which drains a vast agricultural and urban landscape before reaching the Gulf of Mexico. The watershed supports diverse aquatic species and is an important migratory corridor for birds and fish. Nutrient management is a key concern in this region due to contributions to the Gulf of Mexico hypoxic zone.
