Elida WWTP and Sewer System - Municipal Wastewater Treatment in Ohio

Elida WWTP and Sewer System is a municipal wastewater treatment facility located at 4000 Dutch Hollow Road in Elida, Allen County, Ohio. The plant serves a population of about 5,195 people, classifying it as a small to medium-sized facility within the state's wastewater infrastructure. As a US-based plant, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting, typically administered by the Ohio Environmental Protection Agency. For a facility of this scale, secondary treatment is the standard requirement, ensuring that effluent meets federal and state water quality standards before discharge. The plant's treated effluent is discharged into local waterways that are part of the Lake Erie watershed, ultimately draining into the Great Lakes system. This connection to the Lake Erie basin underscores the importance of effective treatment to protect downstream aquatic ecosystems and drinking water sources.

The plant discharges into tributaries of the Ottawa River, which flows into the Maumee River and then into Lake Erie. The Maumee River watershed is a major contributor of nutrients to Lake Erie, making nutrient removal a key ecological concern. The region supports diverse aquatic life and is important for migratory birds along the Great Lakes flyway.
