Edgerton WWTP - Secondary Wastewater Treatment in Edgerton, Missouri

Edgerton WWTP is a municipal wastewater treatment facility located in Edgerton, Platte County, Missouri. The plant serves a small population of 546 residents, reflecting its role in a rural community. As a secondary treatment plant, it provides biological treatment to remove organic matter and suspended solids, meeting typical standards for smaller agglomerations in the United States. The plant operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all point-source discharges. Facilities of this scale are typically regulated by the Missouri Department of Natural Resources to ensure compliance with water quality standards. The plant's designed capacity of 280.12 megaliters per year indicates it has some reserve capacity for future growth. The treated effluent is discharged into a local waterway that ultimately drains into the Missouri River watershed. The Missouri River flows into the Mississippi River, which empties into the Gulf of Mexico. This downstream connection highlights the plant's role in protecting water quality in a major river basin that supports diverse aquatic life and provides drinking water for millions.

The plant discharges into a tributary of the Missouri River, which flows into the Mississippi River and eventually the Gulf of Mexico. This watershed supports a variety of fish species and migratory birds. The Missouri River is a critical water source for agriculture and communities downstream, making effective wastewater treatment essential to prevent nutrient pollution and protect aquatic ecosystems.
