Geauga Co Aquilla WWTP - Advanced Wastewater Treatment in Aquilla, Ohio

The Geauga Co Aquilla WWTP is a municipal wastewater treatment facility located in Aquilla, Geauga County, Ohio. It serves a small population of 480 residents, reflecting its role in a rural community. The plant is situated inland, more than 10 km from the coast, and contributes to local water quality management. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 264.98 megaliters per year and an actual discharge volume of 189.27 megaliters per year, the facility operates below its full capacity. As a US plant, it is subject to the Clean Water Act and operates under an NPDES permit issued by the Ohio Environmental Protection Agency, ensuring compliance with discharge limits. The treated effluent is discharged into a local water body that eventually drains into the Lake Erie basin via the Grand River or Chagrin River watersheds. Lake Erie is a vital freshwater resource that supports drinking water, recreation, and diverse aquatic life. The plant's advanced treatment helps protect downstream water quality in this sensitive Great Lakes ecosystem.

The plant's discharge enters a tributary of the Grand River or Chagrin River, both of which flow north into Lake Erie. Lake Erie is the shallowest and most biologically productive of the Great Lakes, supporting a major fishery and providing drinking water for millions. The watershed is characterized by agricultural and rural land use, making nutrient management critical to prevent algal blooms. Advanced treatment at this plant reduces phosphorus and nitrogen loads, helping to maintain the ecological health of the lake.
