MAYSVILLE WWTP is a municipal wastewater treatment facility located in Maysville, Missouri, a small town in DeKalb County. The plant serves a population of approximately 1,002 residents, reflecting its role in managing domestic wastewater for the local community. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 605.66 cubic meters per day and an average daily discharge of 302.83 cubic meters, the facility operates at about half its capacity. As a US plant, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. The treated effluent is discharged into a local waterway, likely a tributary of the Grand River or the Missouri River system. This discharge supports the health of downstream aquatic ecosystems and contributes to the overall water quality of the Mississippi River basin. The plant's secondary treatment ensures compliance with federal standards for protecting receiving waters.

The plant discharges into a local stream that flows into the Grand River, a tributary of the Missouri River, which ultimately drains into the Mississippi River and the Gulf of Mexico. The receiving waters support diverse aquatic life, including fish and macroinvertebrates, and are part of a larger watershed that provides habitat and recreational opportunities. The plant's secondary treatment helps reduce nutrient loading and organic pollution, mitigating impacts on downstream ecosystems.
