Stratford WWTP - Advanced Wastewater Treatment in Stratford, Wisconsin

Stratford WWTP is an advanced wastewater treatment plant located in Stratford, Marathon County, Wisconsin, United States. The facility serves a population of approximately 1,566 residents, reflecting its role as a small municipal treatment system in central Wisconsin. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 889.57 and a discharge volume of 492.10, the plant operates under the U.S. Clean Water Act, which requires NPDES permits for all point source discharges. Such permits set effluent limits to protect water quality. The treated effluent is discharged into a local water body that ultimately drains into the Wisconsin River basin and then to the Mississippi River. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The plant's advanced treatment helps minimize nutrient loading and protects the ecological health of the receiving waters.

The plant discharges into a tributary of the Wisconsin River, which flows into the Mississippi River and eventually to the Gulf of Mexico. The Wisconsin River basin supports a variety of fish and wildlife, including migratory birds and freshwater mussels. Advanced treatment at this plant reduces nutrient pollution, helping to mitigate hypoxia in the Gulf of Mexico.
