REESEVILLE WWTP serves the Town of Lowell in Dodge County, Wisconsin, treating wastewater for a population of approximately 710 residents. The facility operates as a secondary treatment plant, meeting standard requirements for municipal wastewater treatment in the United States. The plant has a designed capacity of 378.54 cubic meters per day and currently discharges an average of 204.41 cubic meters per day, indicating operational capacity below design levels. As a US facility, it operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Wisconsin Department of Natural Resources, which set effluent limits for secondary treatment. The treated effluent from REESEVILLE WWTP discharges into local streams that flow into the Rock River, a major tributary of the Mississippi River. The Rock River basin supports diverse aquatic life and provides habitat for fish species such as walleye and smallmouth bass. Downstream, the Mississippi River is a critical migratory corridor for birds and fish, and its watershed drains into the Gulf of Mexico.

The plant discharges into local waterways within the Rock River basin, which flows southward to join the Mississippi River near the Illinois border. The Rock River supports diverse aquatic ecosystems, including wetlands and floodplain forests that provide habitat for waterfowl and fish. Downstream, the Mississippi River is a major ecological corridor, and its waters eventually reach the Gulf of Mexico, where nutrient loading from upstream sources can contribute to hypoxic zones.
