DEXTER STP - Dexter, Michigan Wastewater Treatment Plant

DEXTER STP is a municipal wastewater treatment plant located on Huron Street in Dexter, Washtenaw County, Michigan. The facility serves a population of approximately 2,338 residents, operating as part of the region's public sanitation infrastructure. As a small-scale treatment plant, it plays a key role in protecting local water quality in this inland community. The plant operates under the regulatory framework of the US Clean Water Act, administered through the National Pollutant Discharge Elimination System (NPDES) by the Michigan Department of Environment, Great Lakes, and Energy (EGLE). For facilities serving populations under 10,000, secondary treatment is typically required, with additional nutrient removal standards in sensitive watersheds. The plant's design and operational practices align with these federal and state requirements. The treated effluent from DEXTER STP is discharged to a local waterway that ultimately drains into the Huron River, a major tributary of Lake Erie. The Huron River watershed supports diverse aquatic life and provides recreational opportunities. The plant's operations help maintain water quality in this ecologically important basin, contributing to the health of the Great Lakes ecosystem.

DEXTER STP discharges into a tributary of the Huron River, which flows into Lake Erie via the Detroit River. The Huron River watershed is a vital freshwater ecosystem supporting fish species like smallmouth bass and walleye, as well as migratory birds. The plant's nutrient management is critical to preventing algal blooms in Lake Erie, a concern for the entire Great Lakes region.
