Ottoville WWTP and Sewer System - Advanced Treatment in Ottoville, Ohio

The Ottoville WWTP and Sewer System is a municipal wastewater treatment facility located in Ottoville, a village in Putnam County, Ohio. Serving a population of 873, the plant is part of the local infrastructure managed by the village. The facility operates under the regulatory framework of the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges to surface waters. The plant provides advanced treatment, a level that goes beyond secondary treatment to remove additional nutrients or contaminants. With a designed capacity of 1,283.25 thousand cubic meters and an annual discharge volume of 533.74 thousand cubic meters, the facility operates well below its capacity. This suggests room for future growth or seasonal variability. The treated effluent from Ottoville WWTP is discharged into a local water body that eventually drains into the Auglaize River, a tributary of the Maumee River, which flows into Lake Erie. The plant plays a role in protecting the Lake Erie watershed, which supports diverse aquatic life and is a vital freshwater resource for the region.

The Ottoville WWTP discharges into a local stream that flows into the Auglaize River, part of the Maumee River basin, which ultimately drains into Lake Erie. Lake Erie is the shallowest of the Great Lakes and is particularly sensitive to nutrient pollution, which can cause harmful algal blooms. The plant's advanced treatment helps reduce nutrient loads, supporting the ecological health of the downstream watershed.
