Portageville WWTP is a municipal wastewater treatment facility located in Portageville, New Madrid County, Missouri, United States. The plant serves a population of approximately 3,228 residents, placing it in the small community category under US regulatory frameworks. As a US-based facility, Portageville WWTP operates under the Clean Water Act, administered by the Environmental Protection Agency (EPA) and delegated to the Missouri Department of Natural Resources. For plants serving fewer than 10,000 people, secondary treatment is typically required, which involves biological processes to reduce organic matter and suspended solids. The plant's treated effluent is discharged into a local waterway that ultimately drains into the Mississippi River basin. The Mississippi River system supports diverse aquatic life and is a critical migratory corridor for birds and fish. Proper treatment helps protect downstream water quality in the Mississippi River and the Gulf of Mexico.

The treated effluent from Portageville WWTP enters a local tributary that flows into the Mississippi River, one of the largest river systems in North America. The Mississippi River basin supports a wide range of aquatic species and provides habitat for migratory birds. Downstream, the river discharges into the Gulf of Mexico, where nutrient pollution can contribute to hypoxic zones. Effective wastewater treatment is essential to minimize nutrient loading and protect this ecologically significant watershed.
