WIXOM STP - Wixom, Michigan Wastewater Treatment Plant

WIXOM STP is a municipal wastewater treatment plant located in Wixom, Oakland County, Michigan, United States. It serves a population of about 13,263 people, classifying it as a small to medium agglomeration under US regulatory frameworks. The plant is situated inland, more than 50 km from the nearest coast, and its operations are subject to the US Clean Water Act and National Pollutant Discharge Elimination System (NPDES) permitting. As a publicly owned treatment works (POTW) in Michigan, the plant is expected to meet secondary treatment standards as defined by the EPA. For a facility of this scale, typical treatment processes include primary sedimentation followed by biological treatment (e.g., activated sludge) and disinfection. It operates under state and federal regulations that mandate compliance with water quality standards for the receiving water body. The treated effluent from WIXOM STP is discharged into local streams that drain into the Huron River watershed, which ultimately flows into Lake Erie via the Detroit River. The Huron River supports diverse aquatic life and is an important recreational and ecological resource in southeastern Michigan. The plant's discharge is regulated to protect downstream water quality and the sensitive Great Lakes ecosystem.

The plant discharges into tributaries of the Huron River, which flows through southeastern Michigan before reaching Lake Erie via the Detroit River. The Huron River watershed supports a variety of fish species and provides habitat for migratory birds. The Great Lakes Basin is a globally significant freshwater resource, and discharges must meet stringent phosphorus and nutrient limits to prevent eutrophication and algal blooms in downstream lakes and rivers.
