Edgerton WWTP and Sewer System - Secondary Treatment Plant in Ohio

Edgerton WWTP and Sewer System is a municipal wastewater treatment facility located in Edgerton, Ohio, serving a population of approximately 2,117 residents. The plant is situated in Williams County, part of the Midwestern United States, and operates under the regulatory framework of the US Clean Water Act. The plant provides secondary treatment, which is the standard level for domestic wastewater in the United States. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The plant has a designed capacity of 1,135.62 thousand cubic meters per year and currently treats an average daily flow of 620.81 thousand cubic meters per year, indicating operational capacity below design levels. The treated effluent is discharged into local receiving waters, likely tributaries of the St. Joseph River or the Maumee River basin, which ultimately drains into Lake Erie. This watershed supports diverse aquatic life and is part of the Great Lakes ecosystem, making proper treatment essential for protecting downstream water quality and recreational uses.

The plant discharges into the St. Joseph River watershed, which flows into the Maumee River and then into Lake Erie. Lake Erie is a vital freshwater resource supporting fisheries, recreation, and drinking water for millions. The region's agricultural land use contributes nutrient runoff, so the plant's secondary treatment helps reduce organic pollutants and suspended solids, mitigating eutrophication risks in the lake.
