PHENORA SUBD SOUTH Wastewater Treatment Plant, Prathersville, Missouri

PHENORA SUBD SOUTH is a municipal wastewater treatment plant located in Prathersville, Boone County, Missouri. The facility serves a small population of 65 residents and provides secondary treatment, which is the standard level for domestic wastewater in the United States under the Clean Water Act. The plant has a designed capacity of 26.50 million gallons per day and discharges a similar volume of treated effluent. As a small-scale facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Missouri Department of Natural Resources, which set limits on effluent quality to protect receiving waters. The treated wastewater is discharged into local waterways that ultimately drain into the Missouri River watershed. The Missouri River flows into the Mississippi River, which empties into the Gulf of Mexico. The plant's operations help maintain water quality in the region's streams and rivers, supporting aquatic life and downstream ecosystems.

The plant discharges into local streams that are part of the Missouri River basin. The Missouri River flows eastward to join the Mississippi River, which carries water to the Gulf of Mexico. The watershed supports diverse aquatic species and provides habitat for migratory birds. Proper treatment is essential to prevent nutrient pollution and protect downstream water quality.
