Butler Co Queen Acres WRF - Millville, Ohio Wastewater Treatment Plant

Butler Co Queen Acres WRF is a municipal wastewater treatment facility located in Millville, Butler County, Ohio. The plant serves a population of approximately 1,400 residents in the Queen Acres area, operating as part of the region's wastewater infrastructure. As a small-scale facility in the United States, the plant is subject to the National Pollutant Discharge Elimination System (NPDES) under the Clean Water Act. This regulatory framework requires permits that set effluent limits based on the receiving water body's capacity and the treatment technology employed. For plants of this size, secondary treatment is typically mandated to reduce organic pollutants and suspended solids. The plant's treated effluent is discharged to a local waterway within the Great Miami River watershed, which ultimately flows into the Ohio River and then the Mississippi River system. This drainage basin supports diverse aquatic life and provides water resources for communities downstream. The plant's operation helps protect local streams from untreated wastewater, maintaining water quality for recreation and ecosystem health.

The plant discharges into a tributary of the Great Miami River, which flows southwest to the Ohio River near Cincinnati. The Ohio River then joins the Mississippi River, draining to the Gulf of Mexico. This watershed supports a variety of fish and wildlife, and the plant's treatment helps prevent nutrient pollution that could cause algal blooms in downstream waters.
