Tionesta Boro STP - Secondary Wastewater Treatment in Tionesta, Pennsylvania

Tionesta Boro STP is a municipal wastewater treatment facility located on Church Street in Tionesta, Forest County, Pennsylvania. The plant serves a small community of about 1,188 people, providing secondary treatment to remove organic matter and suspended solids from domestic wastewater. As a secondary treatment plant, it meets the minimum federal standard under the U.S. Clean Water Act for publicly owned treatment works. The plant has a designed capacity of 946.35 cubic meters per day and discharges a similar volume of treated effluent. Secondary treatment typically involves biological aeration and clarification. The treated effluent is discharged into a receiving water body within the Allegheny River basin, which ultimately flows into the Ohio River and then the Mississippi River to the Gulf of Mexico. The plant plays a key role in protecting local water quality in the forested region of northwestern Pennsylvania.

The plant discharges into a tributary of the Allegheny River, which flows through the Allegheny National Forest region before joining the Ohio River. The downstream environment supports diverse aquatic life, including game fish species, and the watershed provides drinking water for downstream communities. The forested landscape helps buffer runoff, but the plant's effluent must meet state water quality standards to protect the river's ecological health.
