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

Girard WWTP and Sewer System is a municipal wastewater treatment facility located in Girard, Trumbull County, Ohio. The plant serves a population of about 19,932 residents, classifying it as a medium-sized agglomeration under typical US regulatory frameworks. As a US facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Ohio Environmental Protection Agency. For plants serving populations of this scale, secondary treatment is the standard requirement, ensuring removal of organic matter and suspended solids before discharge. The treated effluent from the plant is discharged into local waterways that ultimately drain into the Mahoning River, a tributary of the Beaver River, which flows into the Ohio River and eventually the Mississippi River system. The plant plays a key role in protecting the water quality of these downstream water bodies and the aquatic ecosystems they support.

The plant discharges into the Mahoning River watershed, which flows through northeastern Ohio and western Pennsylvania before joining the Beaver River. The Beaver River then empties into the Ohio River, a major tributary of the Mississippi River system. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The plant's operations help maintain water quality in this ecologically important river system, which is subject to industrial and agricultural influences in the region.
