Curryville WWTP - Secondary Wastewater Treatment in Curryville, Missouri

Curryville WWTP is a municipal wastewater treatment facility located in Curryville, Pike County, Missouri. The plant serves a small population of 225 residents, reflecting the rural character of the area. It operates under the regulatory framework of the United States 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 required for most municipal facilities in the U.S. Its designed capacity is 287.69 thousand cubic meters, and the actual discharge volume is 75.71 thousand cubic meters per year, indicating operational capacity well below design. As a small plant, it is subject to state-level oversight by the Missouri Department of Natural Resources. The treated effluent is discharged to a local waterway, likely a tributary of the Mississippi River basin. The plant's inland location, over 50 km from the coast, means its discharge affects freshwater ecosystems rather than marine environments. The receiving water body supports local aquatic life and contributes to the overall health of the Mississippi River watershed.

The plant discharges into a local stream within the Mississippi River basin, which ultimately drains to the Gulf of Mexico. The watershed supports diverse freshwater species and is part of a larger network of rivers and wetlands that provide habitat for fish, birds, and other wildlife. Downstream, the Mississippi River carries nutrients and sediments that can affect coastal zones, making nutrient management important for preventing hypoxic zones in the Gulf.
