Geauga Co Willow Hills WWTP - Advanced Treatment Plant in Chesterland, Ohio

Geauga Co Willow Hills WWTP is a municipal wastewater treatment facility located in Chesterland, Geauga County, Ohio. The plant serves a small population of 81 residents and is situated inland but within 10 km of the Lake Erie coast. It is part of the regional wastewater infrastructure managed by Geauga County. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 45.42 volume units and a discharge volume of 45.43, it operates near full capacity. As a US facility, it is subject to the Clean Water Act and National Pollutant Discharge Elimination System (NPDES) permitting, typically enforced by the Ohio Environmental Protection Agency. The treated effluent is discharged into local waterways that ultimately drain into Lake Erie, part of the Great Lakes system. Lake Erie supports diverse aquatic life and provides drinking water for millions. The plant's advanced treatment helps protect this sensitive freshwater ecosystem from nutrient pollution and other contaminants.

The plant discharges into streams that flow into the Grand River or Chagrin River watersheds, both of which drain into Lake Erie. Lake Erie is the shallowest of the Great Lakes and is particularly vulnerable to algal blooms caused by nutrient loading. The advanced treatment at this plant helps reduce phosphorus and nitrogen inputs, supporting the lake's ecological health and recreational uses.
