The Shelby WWTP and Sewer System is a municipal wastewater treatment facility located in Shelby, Ohio, serving a population of about 9,821. The plant is situated in Richland County and is part of the community's essential water infrastructure. As a US facility serving a medium-sized agglomeration, the plant is subject to the Clean Water Act and operates under an NPDES permit issued by the Ohio Environmental Protection Agency. For plants of this scale, secondary treatment is typically required, with possible additional nutrient removal depending on the receiving water body's sensitivity. The plant discharges treated effluent into local waterways that drain into the Lake Erie basin via the Huron River or Black River systems. This watershed supports diverse aquatic life and provides drinking water for downstream communities, making proper treatment critical for regional water quality.

The plant's treated effluent flows into tributaries of the Huron River or Black River, which ultimately drain into Lake Erie, part of the Great Lakes system. Lake Erie is ecologically sensitive, supporting important fisheries and providing drinking water for millions. Nutrient loading from wastewater can contribute to algal blooms, so effective treatment is essential for protecting this vital freshwater resource.
