Lathrop WWTP - Secondary Wastewater Treatment in Lathrop, Missouri

Lathrop WWTP is a municipal wastewater treatment plant located in Lathrop, Clinton County, Missouri, United States. It serves a population of about 2,086 people, classifying it as a small-scale facility within the state's wastewater infrastructure. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater. With a designed capacity of 870.64 and an average discharge volume of 719.23, the plant operates below its capacity, indicating room for future growth. The facility is regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Missouri Department of Natural Resources. The treated effluent is discharged into a local waterway, likely a tributary of the Missouri River, which flows into the Mississippi River and ultimately the Gulf of Mexico. The plant plays a key role in protecting local water quality and downstream ecosystems from nutrient pollution and pathogens.

The plant discharges into a receiving water body within the Missouri River basin, which drains into the Mississippi River and then the Gulf of Mexico. This watershed supports diverse aquatic life and is an important migratory corridor for fish and birds. The secondary treatment process helps reduce organic pollutants and suspended solids, mitigating eutrophication risks in downstream waters.
