Knapp WWTP - Secondary Treatment Plant in Town of Stanton, Wisconsin

Knapp WWTP is a municipal wastewater treatment facility located on US Highway 12 in the Town of Stanton, Dunn County, Wisconsin. The plant serves a small population of 428 residents and operates as part of the local wastewater infrastructure in this rural area of the state. The plant provides secondary treatment, which is the standard level required under the US Clean Water Act for municipal facilities. With a designed capacity of 158.99 million gallons per year and an actual discharge volume of 87.06 million gallons, the plant operates well below its capacity, indicating room for future growth or seasonal variability. The treated effluent from Knapp WWTP is discharged into local waterways that ultimately drain into the Mississippi River basin. The plant's location in western Wisconsin places it within the larger Upper Mississippi River watershed, which supports diverse aquatic life and provides drinking water for millions downstream.

Knapp WWTP discharges into tributaries of the Red Cedar River, which flows into the Chippewa River and then the Mississippi River. The Mississippi River is a major ecological corridor supporting diverse fish, mussel, and bird species. The plant's secondary treatment helps protect water quality in this sensitive river system by reducing organic pollutants and suspended solids before discharge.
