Altamont V STP is a municipal wastewater treatment facility located in the Town of Guilderland, Albany County, New York. It serves a population of approximately 1,427 residents, classifying it as a small-scale treatment plant under U.S. EPA guidelines. The plant provides secondary treatment, which is the standard level required by the Clean Water Act for most municipal facilities in the United States. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The plant has a designed capacity of 1,854.85 units and currently discharges 715.44 units, indicating it operates below its full capacity. The treated effluent is discharged into a local water body, which ultimately drains into the Hudson River watershed. The Hudson River is a major estuary that flows into the Atlantic Ocean, supporting diverse aquatic life and serving as a critical habitat for migratory fish species. The plant's operations are regulated under the National Pollutant Discharge Elimination System (NPDES) permit program to ensure compliance with water quality standards.

The plant discharges into a tributary of the Hudson River, which flows southward through eastern New York to New York Harbor and the Atlantic Ocean. The Hudson River estuary supports a variety of fish, including striped bass and American shad, and is an important migratory corridor. The surrounding watershed includes mixed urban and agricultural land uses, and the plant's secondary treatment helps protect downstream water quality.
