Britton Ridgeway Sewerage Wastewater Treatment Plant, Britton, Michigan

Britton Ridgeway Sewerage is a municipal wastewater treatment plant located in Britton, Lenawee County, Michigan. The facility serves a population of approximately 1,759 residents and operates under the regulatory framework of the U.S. Clean Water Act, which requires secondary treatment for municipal plants of this scale. The plant has a designed capacity of 719.23 thousand gallons per day and currently treats an average daily flow of 643.52 thousand gallons per day. The plant provides secondary treatment, which involves biological processes to remove organic matter and suspended solids. As a facility in the Great Lakes region, it must comply with Michigan's stringent water quality standards aimed at protecting the sensitive aquatic ecosystems of the Great Lakes basin. The plant's discharge is regulated under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Michigan Department of Environment, Great Lakes, and Energy (EGLE). The treated effluent from Britton Ridgeway Sewerage ultimately drains into the Lake Erie watershed via the River Raisin or nearby tributaries. Lake Erie is the shallowest and most biologically productive of the Great Lakes, supporting diverse fish populations and serving as a critical migratory stopover for waterfowl. The plant's operations play a key role in maintaining water quality in this ecologically significant basin.

The plant discharges into the Lake Erie drainage basin, specifically via the River Raisin watershed. Lake Erie is the southernmost Great Lake and supports a rich ecosystem including walleye, perch, and waterfowl. The region is agriculturally intensive, making nutrient management critical to prevent algal blooms in the lake. The plant's secondary treatment helps reduce organic and nutrient loads to the receiving waters.
