Troy Southeast WWTP - Municipal Wastewater Treatment in Troy, Missouri

Troy Southeast WWTP is a municipal wastewater treatment facility located at 336 Commercial Drive in Troy, Lincoln County, Missouri. The plant serves a population of about 5,420 people, placing it in the small-to-medium agglomeration category under US regulatory frameworks. As a US facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting. The plant's design and operation are overseen by state and local authorities to ensure compliance with water quality standards. The plant's treated effluent is discharged into local streams that flow into the Mississippi River basin, ultimately reaching the Gulf of Mexico. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The plant plays a key role in protecting water quality in the region by reducing pollutant loads before discharge.

The plant discharges into tributaries of the Mississippi River, which drains a vast watershed across the central United States before emptying into the Gulf of Mexico. This river system supports important fisheries and migratory bird habitats. The plant's location in a rural area means its discharge can affect local stream ecology, making nutrient removal and pathogen control critical for downstream water quality.
