Grand View SD 1 STP - Advanced Wastewater Treatment in Town of Grandview, Wisconsin

Grand View SD 1 STP is a municipal wastewater treatment facility located in the Town of Grandview, Bayfield County, Wisconsin, United States. The plant serves a small population of 235 residents, providing advanced treatment to protect local water quality. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 124.92 million gallons and an annual discharge volume of 37.85 million gallons, the facility operates well within its capacity. As a US plant, it operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Wisconsin Department of Natural Resources. The treated effluent is discharged into a local water body that ultimately drains into Lake Superior, the largest of the Great Lakes. This watershed supports diverse aquatic life and provides drinking water for millions. The plant's advanced treatment helps minimize nutrient loading and protects the sensitive Lake Superior ecosystem.

The plant discharges into a tributary of the Lake Superior basin, which is part of the Great Lakes system. Lake Superior is the largest freshwater lake by surface area and supports a unique cold-water fishery, including lake trout and whitefish. The watershed is ecologically sensitive, with forested headwaters and wetlands that provide critical habitat. Advanced treatment at this plant helps reduce phosphorus and nitrogen inputs, mitigating the risk of algal blooms and maintaining water quality in this globally significant freshwater resource.
