Huron Valley WWTP South - Rockwood, Michigan Wastewater Treatment Plant

Huron Valley WWTP South is a municipal wastewater treatment facility located in Rockwood, Michigan, serving a population of about 48,178. The plant is situated in Wayne County, near the western shore of Lake Erie, and is part of the region's wastewater infrastructure. As a facility serving a medium-sized agglomeration, the plant is expected to meet secondary treatment standards under the US Clean Water Act. The National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Michigan Department of Environment, Great Lakes, and Energy (EGLE), governs its discharge requirements. The plant's designed capacity is 1.00 million gallons per day, indicating a scale appropriate for its service area. The plant's treated effluent ultimately discharges into the Detroit River, which flows into Lake Erie, a vital freshwater resource and part of the Great Lakes system. The watershed supports diverse aquatic life and provides drinking water for millions. The plant's operation is critical for protecting water quality in this ecologically sensitive region, particularly given the proximity to Lake Erie, which has experienced harmful algal blooms linked to nutrient pollution.

The plant discharges into the Detroit River, which flows into Lake Erie, the shallowest and most biologically productive of the Great Lakes. Lake Erie supports a major fishery and provides drinking water for millions. The watershed is ecologically sensitive, with concerns about nutrient loading contributing to harmful algal blooms. The plant's treatment performance directly affects downstream water quality in the river and lake ecosystem.
