Fairhaven TWP Wastewater Treatment Plant, Fairhaven Township, Michigan

Fairhaven TWP is a municipal wastewater treatment plant located in Fairhaven Township, Huron County, Michigan, along Pigeon Road. The facility serves a small population of approximately 1,109 residents, typical of a rural agglomeration in the Great Lakes region. Its location near the Lake Huron coast places it within a sensitive freshwater ecosystem. The plant provides secondary treatment, which is the standard required by the US Clean Water Act for municipal facilities discharging to surface waters. With a designed capacity of 757.08 cubic meters per day and a reported discharge volume of 567.81 cubic meters per day, the plant operates below its design capacity. As a US facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Michigan Department of Environment, Great Lakes, and Energy (EGLE), ensuring compliance with water quality standards. The treated effluent is discharged into the Lake Huron watershed, a major Great Lake that provides drinking water, recreation, and habitat for diverse aquatic species. The plant's proximity to the coast (within 10 km) means its discharge can directly influence nearshore water quality, making nutrient and pathogen control critical for protecting the lake's ecological health.

The plant discharges into the Lake Huron basin, part of the Great Lakes system that drains into the St. Lawrence River and ultimately the Atlantic Ocean. Lake Huron supports a rich fishery, including lake trout and whitefish, and provides habitat for migratory birds. The nearshore zone is ecologically sensitive to nutrient loading, which can cause algal blooms. The plant's secondary treatment helps reduce organic pollutants and suspended solids, but additional nutrient removal may be needed to protect the lake's oligotrophic conditions.
