Madison WWTP - Secondary Treatment Plant in Madison, Kansas

Madison WWTP is a municipal wastewater treatment plant located on East Main Street in Madison, Greenwood County, Kansas. The facility serves a population of approximately 957 residents, classifying it as a small-scale treatment operation within the state's wastewater infrastructure. The plant provides secondary treatment, which is the standard biological treatment process required by the U.S. Clean Water Act for municipal facilities. With a designed capacity of 423.96 thousand cubic meters per year and an actual discharge volume of 325.55 thousand cubic meters per year, the plant operates below its maximum capacity, indicating room for future growth. The treated effluent is discharged into local waterways that ultimately drain into the Verdigris River basin, part of the larger Arkansas River watershed. This region supports agricultural activities and diverse aquatic habitats, making proper wastewater treatment essential for maintaining water quality downstream.

The plant's discharge enters the Verdigris River basin, which flows into the Arkansas River and eventually reaches the Mississippi River system. This watershed supports a mix of agricultural and natural ecosystems, including fish and wildlife that depend on clean water. The secondary treatment process helps reduce organic pollutants and protect downstream water quality.
