Concordia N Lagoon Wastewater Treatment Plant, Lafayette County, Missouri

Concordia N Lagoon is a wastewater treatment facility located in Lafayette County, Missouri, United States. The plant serves a small population of approximately 1,650 residents, reflecting its role in a rural or small-town community within the state. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 2,687.63 units and an average daily discharge of 605.67 units, the facility operates well below its capacity, indicating room for future growth. As a US plant, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Missouri Department of Natural Resources, which regulate effluent quality to protect receiving waters. The treated effluent is discharged into local waterways that ultimately drain into the Missouri River watershed, a major tributary of the Mississippi River. This contributes to the overall water quality management of the region, supporting downstream aquatic ecosystems and recreational uses.

The plant discharges into local streams that flow into the Missouri River, which then joins the Mississippi River before reaching the Gulf of Mexico. This watershed supports diverse aquatic life and is important for regional water quality. The secondary treatment process helps reduce nutrient and pollutant loads, protecting downstream habitats and drinking water sources.
