Silver Lake SD STP is a municipal wastewater treatment plant located in the Town of Dakota, Waushara County, Wisconsin. The facility serves a population of approximately 4,361 residents, classifying it as a small to medium agglomeration under US EPA guidelines. Its location in rural Wisconsin places it within the Lake Michigan drainage basin, contributing to the region's water quality management. As a US-based plant, Silver Lake SD STP operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting. Plants of this scale typically employ secondary treatment, which is the minimum standard for municipal wastewater facilities under federal regulations. The designed capacity is 1.00 million gallons per day, indicating the plant's infrastructure is sized for the local population. The treated effluent from Silver Lake SD STP is discharged into nearby surface waters that ultimately flow into Lake Michigan. This receiving water body is a major freshwater resource supporting diverse aquatic life and providing drinking water for millions. The plant's performance is critical to protecting downstream ecosystems and maintaining water quality standards in the Lake Michigan basin.

Silver Lake SD STP discharges into local streams and rivers that are part of the Lake Michigan watershed. Lake Michigan is one of the largest freshwater lakes in the world, supporting a rich ecosystem of fish, birds, and aquatic plants. The plant's effluent must meet stringent water quality standards to prevent nutrient pollution and protect the lake's ecological health, particularly given its importance for recreation and drinking water supply.
