Fountain N Lakes WWTP - Secondary Treatment Plant in Fountain N' Lakes, Missouri

Fountain N Lakes WWTP is a municipal wastewater treatment facility located in Fountain N' Lakes, a small community in Lincoln County, Missouri, United States. The plant serves a population of approximately 165 residents, reflecting its role as a small-scale treatment facility for the local area. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 113.56 units and a current discharge volume of 37.85 units, the facility operates well below its capacity. Under the U.S. Clean Water Act, such plants are regulated through National Pollutant Discharge Elimination System (NPDES) permits, which set effluent limits to protect water quality. The treated effluent is discharged into a local water body, which ultimately drains into the Mississippi River basin. The Mississippi River system supports diverse aquatic life and provides drinking water for millions downstream. Proper treatment at this plant helps maintain the ecological health of the regional watershed.

The plant discharges into a local stream that flows into the Mississippi River basin, a major drainage system that empties into the Gulf of Mexico. The Mississippi River supports a wide range of fish and wildlife, including migratory birds and freshwater mussels. Downstream, the river's nutrient levels are a concern, as excess nitrogen and phosphorus can contribute to hypoxia in the Gulf. Effective secondary treatment at this plant helps reduce the local nutrient load.
