SCOTT SD 1 STP - Secondary Wastewater Treatment in Town of Scott, Wisconsin

SCOTT SD 1 STP is a municipal wastewater treatment plant located on CTH A in Beechwood, Town of Scott, Sheboygan County, Wisconsin. The plant serves a small population of 195 residents, reflecting its role in a rural community. It operates under the regulatory framework of the United States Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant provides secondary treatment, a standard level that removes biodegradable organic matter and suspended solids. With a designed capacity of 60.57 volume units and a discharge volume of 53.00 units, the facility operates below its design capacity, indicating adequate treatment capacity for current demand. Secondary treatment typically involves biological processes such as activated sludge or trickling filters. The treated effluent is discharged into local streams that drain into the Lake Michigan watershed. Lake Michigan is a major freshwater resource supporting diverse aquatic life, recreational activities, and municipal water supplies. The plant's location within 50 km of the coast but beyond 10 km means it contributes to the overall nutrient loading in the basin, though its small scale limits its impact.

The plant discharges into tributaries of the Lake Michigan basin, a large freshwater system that ultimately drains into the Atlantic Ocean via the St. Lawrence River. The watershed supports diverse aquatic species, including fish and migratory birds, and is ecologically sensitive to nutrient pollution. The plant's secondary treatment helps reduce organic load, but nutrient removal may be limited, contributing to local water quality management challenges.
