Napoleon WWTP and Sewer System - Municipal Wastewater Treatment in Napoleon, Ohio

The Napoleon WWTP and Sewer System is a municipal wastewater treatment facility located at 798 East Washington Street in Napoleon, Ohio. Serving a population of around 9,318, the plant is part of the city's essential infrastructure for managing domestic and industrial wastewater in Henry County. As a US facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Ohio Environmental Protection Agency. For a community of this size, secondary treatment is typically required, with possible additional nutrient removal to protect downstream water quality. The plant's treated effluent is discharged into the Maumee River, a major tributary of Lake Erie. The Maumee River basin is the largest watershed in the Great Lakes region, supporting diverse aquatic life and providing drinking water for millions. The plant plays a key role in protecting Lake Erie from nutrient pollution and harmful algal blooms.

The Napoleon WWTP discharges into the Maumee River, which flows northeast into Maumee Bay and ultimately Lake Erie. The Maumee River watershed is agriculturally intensive, contributing nutrient loads that can fuel algal blooms in Lake Erie. The plant's treatment processes help mitigate local impacts on the river's aquatic ecosystem and downstream lake health.
