Fairfield Twp Weston WWSL - Seneca Township, Michigan Wastewater Treatment Plant

Fairfield Twp Weston WWSL is a municipal wastewater treatment plant located in Seneca Township, Lenawee County, Michigan. It serves a small population of 355 residents, providing secondary treatment to meet local water quality standards. The plant is situated in a rural area of southeastern Michigan, near the Ohio border. The facility operates with a designed capacity of 189.27 megaliters per year and currently discharges 151.42 megaliters annually. As a secondary treatment plant, it uses biological processes to remove organic matter and suspended solids. Under the US Clean Water Act, such plants must comply with National Pollutant Discharge Elimination System (NPDES) permits issued by the Michigan Department of Environment, Great Lakes, and Energy (EGLE). The treated effluent is discharged into local waterways that ultimately drain into the Lake Erie basin via the Maumee River system. This region is part of the Great Lakes watershed, which supports diverse aquatic life and provides drinking water for millions. The plant's operation helps protect downstream water quality in this ecologically sensitive area.

The plant discharges into tributaries of the Maumee River, which flows into Lake Erie, part of the Great Lakes system. Lake Erie is a vital freshwater resource supporting fisheries, recreation, and municipal water supplies. The watershed faces challenges from nutrient pollution, and secondary treatment helps reduce organic loads and protect aquatic habitats in the downstream environment.
