ROBERTSVILLE WWTP - Franklin County, Missouri Wastewater Treatment Plant

ROBERTSVILLE WWTP is a municipal wastewater treatment facility located in Franklin County, Missouri, United States. The plant serves a small population of around 200 residents, reflecting its role in a rural or small community setting. It operates under the regulatory framework of the U.S. Clean Water Act, which governs wastewater discharges through National Pollutant Discharge Elimination System (NPDES) permits. The plant provides secondary treatment, a standard biological process that significantly reduces organic matter and suspended solids. With a designed capacity of 280.12 units and an actual discharge volume of 45.43 units, the facility operates well below its capacity, indicating ample headroom for future growth or seasonal variations. The treatment process aligns with typical requirements for small-scale plants in the region. The treated effluent is discharged into a local water body, likely a stream or river within the Meramec River watershed, which ultimately flows into the Mississippi River. This downstream connection highlights the plant's role in protecting water quality in the broader Mississippi River Basin, a critical ecological and economic resource. The plant's operations help safeguard local aquatic habitats and downstream communities.

The plant discharges into a receiving water body within the Meramec River watershed, which drains into the Mississippi River. The Mississippi River is a major ecological corridor supporting diverse fish and wildlife, including migratory birds and endangered species. The plant's secondary treatment helps reduce nutrient and pollutant loads, protecting downstream water quality in this nationally significant river system.
