Warren Township Stage V STP - Advanced Wastewater Treatment in Warren Township, New Jersey

Warren Township Stage V STP is an advanced wastewater treatment facility located in Warren Township, Somerset County, New Jersey. The plant serves a small population of approximately 1,311 residents, providing advanced treatment to protect local water quality. As a municipal facility, it plays a key role in managing wastewater from the township and surrounding areas. The plant operates with advanced treatment processes, which go beyond secondary treatment to remove additional pollutants such as nutrients. With a designed capacity of 1,438.45 thousand gallons per day and an actual discharge volume of 454.25 thousand gallons per day, the plant has ample capacity for current flows. Under the U.S. Clean Water Act, such facilities are regulated through National Pollutant Discharge Elimination System (NPDES) permits issued by the New Jersey Department of Environmental Protection, ensuring compliance with water quality standards. The treated effluent is discharged into a local water body that ultimately drains into the Raritan River basin and then to Raritan Bay, part of the New York-New Jersey Harbor Estuary. This estuary supports diverse aquatic life and is an important ecological and recreational resource. The plant's advanced treatment helps reduce nutrient loading and protect downstream habitats.

The plant discharges into a tributary of the Raritan River, which flows into Raritan Bay and the New York-New Jersey Harbor Estuary. This estuary is a critical habitat for fish, birds, and other wildlife, supporting both migratory species and resident populations. Advanced treatment at the plant helps minimize nutrient pollution, which can cause algal blooms and oxygen depletion in sensitive coastal waters.
