Washburn WWTP - Wastewater Treatment Plant in Washburn, Wisconsin, United States

Washburn WWTP is a municipal wastewater treatment facility located in Washburn, Wisconsin, along the Lake Superior shoreline. The plant serves a population of 2,129 residents in this small city within Bayfield County. As a facility in the United States, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting, typically administered by the Wisconsin Department of Natural Resources. The plant has a designed capacity of 1.00 million gallons per day, indicating it is sized for a small community. US plants of this scale commonly employ secondary treatment, which is the minimum standard under the Clean Water Act for municipal wastewater. The plant's operational status and permit details are not publicly listed, but it is assumed to be active given its role in the community. Wastewater effluent from the plant is discharged into the Lake Superior watershed, likely via a local waterway or directly into the lake. Lake Superior is the largest of the Great Lakes and a critical freshwater resource, supporting diverse aquatic life and providing drinking water for millions. The plant's proximity to the coast underscores the importance of effective treatment to protect water quality in this sensitive ecosystem.

The plant discharges into the Lake Superior basin, part of the Great Lakes system, which ultimately drains through the St. Lawrence River to the Atlantic Ocean. Lake Superior is a cold, deep oligotrophic lake with high water clarity and low nutrient levels, making it sensitive to nutrient pollution. The local watershed includes forested and rural areas, with the plant's effluent potentially affecting nearshore habitats and recreational waters. Protecting water quality is critical for the lake's native fish species and overall ecological health.
