Warren County Paulinskill SA CS_STP - Projected Wastewater Treatment Plant in Blairstown, New Jersey

Warren County Paulinskill SA CS_STP is a planned wastewater treatment facility located on Douglas Street in Blairstown, New Jersey. The plant is designed to serve a population of 3,210 residents in the Paulinskill Sewerage Authority service area. As a projected facility, it is not yet operational but represents an investment in local wastewater infrastructure. Once constructed, the plant will be subject to the U.S. Clean Water Act and National Pollutant Discharge Elimination System (NPDES) permitting requirements. For a facility of this scale, secondary treatment is typically mandated, with possible additional nutrient removal if the receiving water body is designated as sensitive. The plant's design capacity and treatment process will be finalized during the engineering phase. The treated effluent will be discharged into the Paulins Kill, a freshwater river that flows through Warren County before joining the Delaware River. The Delaware River is a major waterway that provides drinking water for millions and supports diverse aquatic life, including migratory fish species. The plant's operation will aim to protect this ecologically significant watershed.

The plant will discharge into the Paulins Kill, a tributary of the Delaware River, which ultimately flows into the Delaware Bay and the Atlantic Ocean. The Delaware River basin is a critical water source for the northeastern United States, supporting diverse fish populations and providing habitat for migratory birds. The plant's discharge must meet water quality standards to protect downstream ecosystems and drinking water intakes.
