West Fallowfield Township STP - Pennsylvania Wastewater Treatment Plant

West Fallowfield Township STP is a municipal wastewater treatment facility located in West Fallowfield Township, Crawford County, Pennsylvania. The plant serves a small population of 400 residents, providing secondary treatment for domestic wastewater in this rural area of northwestern Pennsylvania. The plant operates under the US Clean Water Act, which requires secondary treatment for municipal wastewater discharges. With a designed capacity of 189.27 cubic meters per day and a similar discharge volume, the facility is sized appropriately for its small service population. As a secondary treatment plant, it uses biological processes to reduce organic matter and suspended solids before discharge. The treated effluent is discharged into local waterways that ultimately drain into the Ohio River basin. The plant's location more than 10 km from the coast means its discharge has no direct marine impact, but it contributes to the overall water quality of the region's freshwater systems, which support diverse aquatic life and provide drinking water sources downstream.

The plant discharges into tributaries of the Ohio River basin, which flows into the Mississippi River and eventually the Gulf of Mexico. The local watershed supports freshwater ecosystems including fish and macroinvertebrate communities. As a secondary treatment plant, it reduces nutrient and organic loads that could otherwise contribute to eutrophication in downstream waters.
