Jackson WWTP - Town of Jackson, Wisconsin Wastewater Treatment Plant

Jackson WWTP is a municipal wastewater treatment facility located in the Town of Jackson, Washington County, Wisconsin. It serves a population of approximately 7,170 residents, classifying it as a small to medium-sized plant under state and federal guidelines. However, as a U.S. facility, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Wisconsin Department of Natural Resources. For plants of this scale, secondary treatment is typically required, with possible additional nutrient removal depending on the receiving water body's sensitivity. The treated effluent is discharged into a local waterway that ultimately drains into the Lake Michigan basin. This watershed supports diverse aquatic life and provides recreational and drinking water resources for the region. The plant's performance is critical to maintaining water quality in downstream ecosystems.

The plant discharges into a tributary of the Milwaukee River, which flows into Lake Michigan. Lake Michigan is a major freshwater resource supporting fisheries, recreation, and municipal water supplies. The watershed is ecologically sensitive, with efforts to reduce nutrient loading to prevent algal blooms and protect aquatic habitats.
