WATERLOO WWTP - Waterloo, Wisconsin Wastewater Treatment Plant

WATERLOO WWTP is a municipal wastewater treatment facility located in Waterloo, Jefferson County, Wisconsin. Serving a population of about 3,640, the plant is part of the region's infrastructure for managing domestic wastewater from this small community in the Midwestern United States. As a US-based facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permit regulations. For a plant of this scale, secondary treatment is typically required, which involves biological processes to reduce organic matter and suspended solids before discharge. The treated effluent is discharged into a local water body that ultimately drains into the Rock River basin, which flows southward to the Mississippi River. This watershed supports diverse aquatic life and provides water for agricultural and recreational uses downstream.

The plant discharges into a tributary of the Rock River, which flows through southern Wisconsin and northern Illinois before joining the Mississippi River. The Rock River watershed supports a variety of fish species and provides habitat for migratory birds. The plant's operations help protect water quality in this important regional waterway, which is used for recreation and as a drinking water source for downstream communities.
