Alexandria Boro Porter Twp JSA Wastewater Treatment Plant, Porter Township, Pennsylvania

The Alexandria Boro Porter Twp JSA wastewater treatment plant is located in Porter Township, Huntingdon County, Pennsylvania, United States. It serves a population of approximately 5,455 people, placing it in the small-to-medium agglomeration category. The plant is situated in a rural area near the Juniata River watershed. As a US facility, the plant 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 a plant of this scale, secondary treatment is the standard requirement, ensuring removal of organic matter and suspended solids before discharge. The plant's treated effluent likely discharges into a tributary of the Juniata River, which flows into the Susquehanna River and ultimately reaches the Chesapeake Bay. This places the plant within the Chesapeake Bay watershed, a large and ecologically significant estuary system that supports diverse aquatic life and is a focus of regional nutrient reduction efforts.

The plant is located in the Juniata River subbasin of the Susquehanna River watershed. The Juniata River flows into the Susquehanna, which empties into the Chesapeake Bay, the largest estuary in the United States. The Chesapeake Bay supports a complex ecosystem including blue crabs, oysters, and migratory fish. Nutrient pollution from wastewater is a key concern in this watershed, driving regulatory focus on phosphorus and nitrogen removal.
