Lyndon Station STP - Advanced Wastewater Treatment in Town of Lyndon, Wisconsin

Lyndon Station STP is a municipal wastewater treatment facility located on Industrial Avenue in the Town of Lyndon, Juneau County, Wisconsin. The plant serves a small population of 526 residents and is part of the region's water infrastructure. The plant provides advanced treatment, which goes beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 238.48 megaliters and an annual discharge volume of 132.49 megaliters, the facility operates under the US Clean Water Act, which requires NPDES permits for all point source discharges. The treated effluent is discharged into a local water body that ultimately drains into the Wisconsin River watershed and then the Mississippi River. The plant's advanced treatment helps protect downstream aquatic ecosystems in this agriculturally intensive region.

The plant discharges into a tributary of the Wisconsin River, which flows into the Mississippi River and eventually the Gulf of Mexico. The Wisconsin River basin supports diverse aquatic life, including fish species such as walleye and smallmouth bass. Advanced treatment at this plant reduces nutrient loading, helping to mitigate downstream eutrophication in the Mississippi River system.
