Delaware Co Alum Creek WWTP - Columbus, Ohio Wastewater Treatment Plant

Delaware Co Alum Creek WWTP is a municipal wastewater treatment facility located in Columbus, Ohio, serving an estimated population of 74,000. The plant is situated in Delaware County and is part of the region's wastewater infrastructure. As a US facility serving a medium-sized agglomeration, the plant is subject to the Clean Water Act and National Pollutant Discharge Elimination System (NPDES) permitting requirements. For plants of this scale, secondary treatment is typically mandated, with additional nutrient removal standards potentially applicable in sensitive watersheds. The plant's treated effluent is discharged into local waterways that ultimately drain into the Ohio River basin. The receiving waters support aquatic life and are part of a larger watershed that provides drinking water and recreational opportunities downstream.

The plant discharges into the Scioto River watershed, which flows south to the Ohio River and eventually the Mississippi River and Gulf of Mexico. The local streams and rivers support diverse fish populations and are important for regional water quality. The watershed faces challenges from agricultural runoff and urban stormwater, making effective wastewater treatment critical for maintaining ecological health.
