Johnsonburg Boro STP is a wastewater treatment plant located in Ridgway Township, Elk County, Pennsylvania, serving a population of about 5,842 residents. The facility is part of the region's municipal wastewater infrastructure, handling domestic sewage from the local community. As a US-based plant serving a small agglomeration, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting, typically administered by the Pennsylvania Department of Environmental Protection. For plants of this scale, secondary treatment is the standard requirement to meet effluent limitations. The plant's treated effluent is discharged into local waterways that ultimately drain into the Ohio River basin, contributing to the broader Mississippi River watershed. The surrounding area features forested terrain and supports diverse aquatic life, making proper treatment essential for maintaining water quality.

The plant discharges into local streams that flow into the Clarion River, a tributary of the Allegheny River, which joins the Ohio River and eventually the Mississippi River. The watershed supports diverse aquatic species and is an important ecological corridor in the Appalachian region. Maintaining treatment standards helps protect downstream water quality and aquatic habitats.
