Cedar Grove Township CS_STP Wastewater Treatment Plant, New Jersey

Cedar Grove Township CS_STP is a municipal wastewater treatment plant located in Cedar Grove, Essex County, New Jersey. It serves a population of approximately 12,300 residents in this suburban community within the New York metropolitan area. The facility is situated near the Passaic River watershed, which drains into Newark Bay and ultimately the Atlantic Ocean. As a U.S. plant serving a medium-sized agglomeration, it operates under the Clean Water Act National Pollutant Discharge Elimination System (NPDES) permit program. The plant is regulated by the New Jersey Department of Environmental Protection (NJDEP) under state and federal guidelines. The treated effluent is discharged into local waterways within the Passaic River basin. This watershed supports diverse aquatic life and provides recreational opportunities. Downstream, the Passaic River flows into Newark Bay, an estuary that is part of the larger New York-New Jersey Harbor Estuary, an ecologically important area for fish migration and waterfowl habitat.

The plant discharges into the Passaic River watershed, which flows through northern New Jersey before entering Newark Bay. This estuary is a critical habitat for migratory fish such as striped bass and American shad, and supports a variety of bird species. The bay connects to the Atlantic Ocean via the Kill Van Kull and Arthur Kill, making the region ecologically sensitive to nutrient loading and pollutant discharges.
