Wonewoc WWTP - Secondary Treatment Plant in Wonewoc, Wisconsin

Wonewoc WWTP is a municipal wastewater treatment facility located in Wonewoc, Wisconsin, United States. The plant serves a small population of 819 residents, reflecting the rural character of the area. It operates under the regulatory framework of the U.S. Clean Water Act, which requires secondary treatment for municipal discharges to protect water quality. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 537.53 units and an average discharge volume of 336.90 units, the facility operates below its capacity, indicating room for future growth. As a small agglomeration, it is subject to state-level NPDES permits that set effluent limits and monitoring requirements. The treated effluent is discharged into a local water body, likely a tributary of the Baraboo River or the Wisconsin River system, which ultimately drains into the Mississippi River. This watershed supports diverse aquatic life and provides recreational opportunities. The plant's inland location reduces direct marine impact, but its discharge contributes to the overall health of the regional river basin.

The plant discharges into a local stream or river within the Wisconsin River basin, which flows into the Mississippi River and eventually the Gulf of Mexico. This watershed supports a variety of fish species and provides habitat for migratory birds. The secondary treatment process helps reduce nutrient loading, protecting downstream water quality in this ecologically sensitive region.
