Farmington Twp STP - Secondary Wastewater Treatment in Farmington Township, Pennsylvania

Farmington Twp STP is a municipal wastewater treatment facility located in Farmington Township, Warren County, Pennsylvania. The plant serves a small population of 192 residents and operates with a designed capacity of 94.64 m³/day, discharging approximately 75.71 m³/day of treated effluent. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal wastewater facilities. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids before discharge. As a small facility, it is subject to state-level NPDES permitting administered by the Pennsylvania Department of Environmental Protection. The treated effluent is discharged into a local waterway that ultimately drains into the Allegheny River basin, part of the larger Ohio River watershed. The plant's location in a rural, inland area means its discharge contributes to local stream health and downstream water quality in the region.

The plant discharges into a tributary of the Allegheny River, which flows into the Ohio River and eventually the Mississippi River system. The local watershed supports diverse aquatic life, including fish species such as smallmouth bass and various macroinvertebrates. The plant's secondary treatment helps protect downstream water quality in this ecologically sensitive region.
