WAUPACA WWTP - Waupaca, Wisconsin Wastewater Treatment Plant

WAUPACA WWTP is a municipal wastewater treatment facility located in Waupaca, Wisconsin, serving a population of about 11,368. The plant is situated inland, more than 50 kilometers from the coast, and plays a key role in managing the city's wastewater. As a US facility, the plant 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 a community of this size, secondary treatment is typically required, and the plant's designed capacity is 1.00 million gallons per day, indicating it is sized to handle the local flow. The treated effluent is discharged into the local watershed, which ultimately drains into the Waupaca River and then the Wolf River system, contributing to the Fox River basin and eventually Lake Michigan. This water body supports diverse aquatic life and is important for regional recreation and ecology.

The plant discharges into the Waupaca River, a tributary of the Wolf River, which flows into the Fox River and ultimately reaches Lake Michigan. This watershed supports a variety of fish species and provides habitat for migratory birds. The area is ecologically sensitive due to its connection to the Great Lakes ecosystem, which requires careful management of nutrient and pollutant loads.
