Phoenix V STP - Wastewater Treatment Plant in Village of Phoenix, New York

Phoenix V STP is a municipal wastewater treatment plant located in the Village of Phoenix, Oswego County, New York. The facility serves a population of approximately 2,251 residents and has a designed capacity of 1.00 million gallons per day, indicating it is a small-scale plant typical of rural communities in upstate New York. As a US-based facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the New York State Department of Environmental Conservation. For small agglomerations like this, secondary treatment is the standard requirement, ensuring removal of organic matter and suspended solids before discharge. The plant's treated effluent is discharged into a local water body that ultimately drains into the Oswego River, which flows into Lake Ontario. This makes the plant part of the Great Lakes Basin, a critical freshwater ecosystem. Proper treatment is essential to protect water quality in the river and lake, supporting aquatic life and recreational uses.

The plant's discharge enters a tributary of the Oswego River, which flows northward into Lake Ontario, one of the five Great Lakes. Lake Ontario supports diverse aquatic life, including fish species such as lake trout and salmon, and serves as a drinking water source for millions. The watershed is ecologically sensitive, and nutrient loading from wastewater can contribute to algal blooms. Effective treatment helps maintain the ecological balance of this important freshwater system.
