Southwest Warren Tidioute STP - Secondary Wastewater Treatment in Triumph Township, Pennsylvania

Southwest Warren Tidioute STP is a municipal wastewater treatment facility located in Triumph Township, Warren County, Pennsylvania. The plant serves a small population of 939 residents and operates under the regulatory framework of the US Clean Water Act. The plant provides secondary treatment, which is the standard level for small communities in the United States. With a designed capacity of 946.35 thousand cubic meters per year and an actual discharge volume of 719.23 thousand cubic meters, the facility operates below its capacity. As a US plant, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Pennsylvania Department of Environmental Protection. The treated effluent is discharged into a local water body that ultimately drains into the Allegheny River, a major tributary of the Ohio River system. This river network supports diverse aquatic life and provides drinking water for downstream communities. The plant's inland location reduces direct marine impact, but its discharge contributes to the overall water quality of the Allegheny watershed.

The plant discharges into a tributary of the Allegheny River, which flows into the Ohio River and eventually the Mississippi River system. The Allegheny River supports a variety of fish species and is an important ecological corridor in northwestern Pennsylvania. The plant's secondary treatment helps protect downstream water quality by reducing organic pollutants and suspended solids.
