Upper Sandusky WWTP and Sewer System | Ohio Wastewater Treatment Plant

The Upper Sandusky WWTP and Sewer System is a municipal wastewater treatment facility located in Upper Sandusky, Wyandot County, Ohio. Serving a population of about 6,800, the plant is part of the community's essential infrastructure for managing domestic and commercial wastewater. As a facility in the United States, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permit requirements. For a community of this size, secondary treatment is typically mandated, with possible additional nutrient removal depending on the receiving water body's sensitivity. The plant's treated effluent is discharged into the Sandusky River watershed, which flows northward into the Sandusky Bay of Lake Erie. This region is part of the Great Lakes Basin, an ecologically significant area that supports diverse aquatic life and provides drinking water for millions. Proper treatment is crucial to prevent nutrient pollution that can cause harmful algal blooms in Lake Erie.

The plant discharges into the Sandusky River, which flows into Sandusky Bay and ultimately Lake Erie. Lake Erie is the shallowest of the Great Lakes and is particularly vulnerable to nutrient pollution, especially phosphorus, which can lead to harmful algal blooms. The watershed supports diverse aquatic habitats and is an important resource for recreation and drinking water.
