Millersburg Wastewater Treatment Plant, Kentucky | Secondary Treatment Facility

The Millersburg wastewater treatment plant is located in Millersburg, Bourbon County, Kentucky, serving a small community of about 982 residents. As a municipal facility, it plays a key role in managing local wastewater in this inland area of the state. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal wastewater. With a designed capacity of 757.08 units and a current discharge volume of 416.40 units, the facility operates below its full capacity. US plants of this scale are typically permitted under the National Pollutant Discharge Elimination System (NPDES), administered by the Kentucky Division of Water. The treated effluent is discharged into a local waterway, likely a tributary of the Licking River or Kentucky River, which ultimately flows to the Ohio River and then the Mississippi River. This drainage network supports diverse aquatic life and provides water resources for communities downstream.

The plant discharges into a local stream within the Kentucky River basin, which flows into the Ohio River and eventually the Mississippi River. This watershed supports diverse aquatic species and provides drinking water for downstream communities. The inland location reduces direct marine impact, but nutrient loading from secondary treatment can affect local water quality and downstream ecosystems.
