Danbury St Croix Chippewa JWQC Wastewater Treatment Plant, Town of Swiss, Wisconsin

Danbury St Croix Chippewa JWQC is a wastewater treatment plant located in the Town of Swiss, Burnett County, Wisconsin, United States. The plant serves a small population of 498 residents, reflecting its role in a rural community near the St. Croix River region. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal wastewater facilities. With a designed capacity of 325.54 megaliters and an annual discharge volume of 151.42 megaliters, the plant operates below its capacity, indicating room for future growth or seasonal variability. The treated effluent is discharged into local waterways that ultimately drain into the St. Croix River, a tributary of the Mississippi River. This watershed supports diverse aquatic life and is an important recreational and ecological corridor in the Upper Midwest. The plant's operations are subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Wisconsin Department of Natural Resources.

The plant discharges into the St. Croix River basin, which flows into the Mississippi River and eventually the Gulf of Mexico. The St. Croix River is a National Scenic Riverway known for its clean water and diverse fish populations. The plant's secondary treatment helps protect this sensitive ecosystem from nutrient pollution and pathogens.
