Hermon V STP and On Sites - Secondary Wastewater Treatment in Town of Russell, New York

Hermon V STP and On Sites is a municipal wastewater treatment facility located in the Town of Russell, Saint Lawrence County, New York. The plant serves a small population of 302 residents and operates under secondary treatment standards, which is the minimum required by the US Clean Water Act for municipal plants. The plant's designed capacity is 227.12 units, and it currently treats an average daily flow of 238.48 units, indicating operation near or slightly above its design capacity. As a US facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the New York State Department of Environmental Conservation, which set effluent limits to protect water quality. The treated effluent is discharged into local waterways that drain into the St. Lawrence River watershed, ultimately reaching the Atlantic Ocean. The plant's location in a rural, inland area means its discharge supports local streams and contributes to the ecological health of the broader St. Lawrence River basin.

The plant discharges into tributaries of the St. Lawrence River, which flows northeast into the Gulf of St. Lawrence and the Atlantic Ocean. The local watershed supports diverse aquatic life, including cold-water fish species. Secondary treatment reduces organic pollutants and suspended solids, helping to maintain water quality in downstream ecosystems.
