Morristown V STP - Secondary Wastewater Treatment in Town of Morristown, New York

Morristown V STP is a municipal wastewater treatment facility located in Terrace Park, Town of Morristown, Saint Lawrence County, New York. The plant serves a small population of 400 residents and provides secondary treatment, which is the standard level for communities of this size under the US Clean Water Act. The plant has a designed capacity of 227.12 megaliters per year and currently discharges 132.49 megaliters per year of treated effluent. As a secondary treatment facility, it uses biological processes to remove organic matter and suspended solids before discharge. The plant is regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the New York State Department of Environmental Conservation. The treated wastewater is discharged into a local waterway that ultimately drains into the St. Lawrence River, which flows into the Gulf of St. Lawrence and the Atlantic Ocean. The plant plays a key role in protecting the water quality of the St. Lawrence River watershed, which supports diverse aquatic life and recreational uses.

The plant discharges into a tributary of the St. Lawrence River, a major waterway that forms part of the Great Lakes drainage basin. The St. Lawrence River is ecologically significant, supporting fish species such as lake sturgeon and walleye, and providing habitat for migratory birds. Downstream, the river flows into the Gulf of St. Lawrence, a critical marine ecosystem. The plant's secondary treatment helps reduce nutrient and pollutant loads, protecting this sensitive watershed.
