Liberty WWTP - Secondary Treatment Plant in Montgomery County, Kansas

Liberty WWTP is a municipal wastewater treatment plant located in Montgomery County, Kansas, United States. The facility serves a small population of approximately 95 residents, reflecting its role as a local-scale treatment system in a rural area. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for most municipal facilities. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The plant's designed capacity is 68.14 units, and it currently treats a daily discharge volume of 37.85 units, indicating operational headroom. The treated effluent is discharged into a local waterway within the Verdigris River basin, which ultimately flows into the Arkansas River and then the Mississippi River system. This downstream connection highlights the plant's role in protecting regional water quality and aquatic habitats in the central United States.

The plant discharges into a tributary of the Verdigris River, which flows through southeastern Kansas into Oklahoma before joining the Arkansas River. The Arkansas River then drains into the Mississippi River, eventually reaching the Gulf of Mexico. The local watershed supports diverse aquatic life and is important for regional biodiversity, including migratory fish species. The plant's secondary treatment helps reduce nutrient and organic pollution, protecting downstream water quality.
