Erie Co Sawmill Creek WWTP - Huron, Ohio Wastewater Treatment Plant

Erie Co Sawmill Creek WWTP is a municipal wastewater treatment facility located in Huron, Ohio, United States. Serving a population of about 6,239, the plant is part of the wastewater infrastructure for Erie County and the surrounding area. The facility is situated near the shores of Lake Erie, one of the Great Lakes, which influences its operational and environmental considerations. The plant has a designed capacity of 1.00 million gallons per day, indicating its scale for a small to medium-sized community. As a US facility, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Ohio Environmental Protection Agency. These permits set limits on effluent quality to protect receiving waters, including requirements for secondary treatment and, where necessary, advanced treatment to address nutrient loading. The treated effluent from the plant is discharged into a waterway that ultimately flows into Lake Erie. Lake Erie is a vital freshwater resource that supports diverse aquatic life, including fish species such as walleye and perch, and provides drinking water for millions. The plant's location within 50 km of the coast underscores the importance of effective treatment to prevent nutrient pollution and harmful algal blooms in the lake.

The plant discharges into a tributary of Lake Erie, part of the Great Lakes Basin. Lake Erie is the shallowest and most biologically productive of the Great Lakes, supporting a rich ecosystem of fish, birds, and aquatic plants. The region is sensitive to nutrient pollution, which can lead to harmful algal blooms that affect water quality and recreation. The plant's treatment processes are critical to minimizing phosphorus and nitrogen loads entering the lake.
