Huntsville NE Lagoon Wastewater Treatment Plant, Randolph County, Missouri

Huntsville NE Lagoon is a wastewater treatment facility located in Randolph County, Missouri, United States. The plant serves a small community with a population equivalent of 250, reflecting its role in rural wastewater management. It operates as a lagoon-based secondary treatment system, a common approach for small agglomerations in the region. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal wastewater. With a designed capacity of 170.34 megaliters and an annual discharge volume of 113.56 megaliters, the facility operates within its capacity. As a small plant, it falls under state-level NPDES permitting, which regulates effluent quality to protect local water resources. The treated effluent from Huntsville NE Lagoon is discharged into local waterways within the Missouri River basin. The plant's location inland, far from coastal areas, means its discharge impacts freshwater ecosystems. The surrounding region relies on these water bodies for agricultural and ecological functions, making proper treatment essential for maintaining water quality.

The plant discharges into tributaries of the Missouri River, which flows into the Mississippi River and ultimately the Gulf of Mexico. The local watershed supports agricultural activities and diverse aquatic life. Proper secondary treatment helps reduce nutrient loading, which is critical for preventing downstream hypoxia in the Gulf.
