LANCASTER WWTP - Secondary Treatment Plant in Lancaster, Missouri

LANCASTER WWTP is a municipal wastewater treatment facility located in Lancaster, Schuyler County, Missouri. It serves a small population of 924 residents, reflecting the rural character of the area. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for most municipal facilities. Under the US Clean Water Act, the plant operates under a National Pollutant Discharge Elimination System (NPDES) permit, which sets limits on effluent quality to protect receiving waters. The plant's designed capacity is 594.31, and its current discharge volume is 264.98, indicating it operates well below capacity. This suggests the plant has room for future growth or seasonal variations. The treated effluent is discharged into a local waterway that ultimately drains into the Mississippi River basin. The plant plays a key role in protecting downstream water quality, including the Mississippi River and the Gulf of Mexico, by reducing nutrient and pollutant loads from the community.

The plant discharges into a local stream that is part of the Mississippi River watershed. This river system flows south to the Gulf of Mexico, where nutrient pollution contributes to hypoxic zones. The plant's secondary treatment helps reduce organic matter and suspended solids, but nutrient removal may be limited. The surrounding area is primarily agricultural, so the plant also helps manage runoff-related pollutants.
