JAMESPORT WWTP - Daviess County, Missouri Wastewater Treatment Plant

JAMESPORT WWTP is a municipal wastewater treatment facility located in Daviess County, Missouri, United States. The plant serves a small population of 524 residents, reflecting its role in a rural community. It operates under the regulatory framework of the US Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant provides secondary treatment, a standard level that removes biodegradable organic matter and suspended solids. Its designed capacity is 287.69 units, and it currently treats an average daily flow of 227.13 units, indicating operational headroom. As a small facility, it is subject to state-level oversight by the Missouri Department of Natural Resources, which issues permits and ensures compliance with water quality standards. The treated effluent is discharged into a local water body, likely a stream or river within the Grand River basin, which ultimately flows into the Missouri River and then the Mississippi River. This downstream connection highlights the plant's role in protecting regional water quality and aquatic ecosystems in the Mississippi River watershed.

The plant discharges into a local watercourse within the Grand River basin, a tributary of the Missouri River. The Missouri River flows into the Mississippi River, which drains into the Gulf of Mexico. This watershed supports diverse aquatic life and is an important migratory corridor for fish and birds. The plant's secondary treatment helps reduce nutrient and organic pollutant loads, mitigating potential impacts on downstream water quality and the hypoxic zone in the Gulf.
