ALTENBURG WWTP - Secondary Treatment Plant in Altenburg, Missouri

ALTENBURG WWTP is a municipal wastewater treatment facility located on Ridge Road in Altenburg, Perry County, Missouri. The plant serves a small population of 606 residents, reflecting the rural character of the community. It operates as part of the state's wastewater infrastructure under the oversight of the Missouri Department of Natural Resources. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 246.05 megaliters and an annual discharge volume of 219.55 megaliters, the facility operates at a utilization rate that suggests adequate capacity for its service area. As a US plant, it is subject to the Clean Water Act and National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. The treated effluent is discharged into a local waterway that drains into the Mississippi River basin. The Mississippi River system supports diverse aquatic life and provides drinking water for millions downstream. The plant's secondary treatment helps reduce nutrient and pollutant loads, contributing to the ecological health of the region's surface waters.

The plant's discharge enters a tributary of the Mississippi River, which flows south to the Gulf of Mexico. The Mississippi River basin is a major ecological corridor, supporting fish, migratory birds, and wetland habitats. Nutrient loading from wastewater can contribute to hypoxia in the Gulf, making effective treatment critical for downstream water quality.
