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

The Elyria WWTP and Sewer System is a municipal wastewater treatment facility serving the city of Elyria in Lorain County, Ohio. With a population served of 57,000, it is classified as a medium-sized agglomeration under US regulatory frameworks. The plant's designed capacity is 1.00 million gallons per day, reflecting its role in managing local wastewater. As a US facility, the plant operates under the Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. For plants serving populations of this scale, secondary treatment is typically mandated, with additional nutrient removal requirements in sensitive watersheds. The plant's treatment processes and operational status are consistent with standard municipal practices. The plant's treated effluent ultimately discharges into the Lake Erie basin, a vital freshwater resource that supports drinking water, recreation, and diverse aquatic life. 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 location within 50 km of the lake underscores its environmental significance in protecting downstream water quality.

The plant discharges into the Lake Erie watershed, part of the Great Lakes system that drains into the Atlantic Ocean via the St. Lawrence River. Lake Erie is ecologically sensitive due to its shallow depth and high nutrient loading, which can lead to eutrophication and harmful algal blooms. The plant's operations are critical for maintaining water quality in this important freshwater ecosystem.
