Eagle Lake UD 1 STP - Wastewater Treatment Plant in Town of Dover, Wisconsin

Eagle Lake UD 1 STP is a municipal wastewater treatment facility located in the Town of Dover, Racine County, Wisconsin. It serves a population of about 2,920 people, placing it in the small community category under US regulatory frameworks. The plant is situated in a rural setting near Eagle Lake, a small inland lake in southeastern Wisconsin. As a small-scale facility, Eagle Lake UD 1 STP is subject to the US Clean Water Act and Wisconsin Department of Natural Resources (WDNR) permitting requirements. Typical treatment for plants of this size includes secondary treatment, often via activated sludge or lagoon systems, to meet effluent limits for biochemical oxygen demand and total suspended solids. The plant's designed capacity is 1.00 million gallons per day, indicating it is sized for its service population. The treated effluent from the plant likely discharges to a nearby water body, possibly Eagle Lake or a tributary of the Fox River system, which ultimately drains to the Mississippi River and the Gulf of Mexico. The plant plays a key role in protecting local water quality and preventing nutrient enrichment in the region's lakes and streams.

The plant discharges into the Fox River watershed, which flows into the Mississippi River and eventually the Gulf of Mexico. This region is part of the Upper Mississippi River Basin, an ecologically important area supporting diverse aquatic life and migratory birds. The plant's operations help control nutrient loading that could contribute to algal blooms in downstream waters.
