It serves a population of approximately 100,677, making it a large agglomeration under regulatory classifications. The plant is situated near the Atlantic coast, within 50 km of the ocean, and plays a key role in managing wastewater for the surrounding communities. As a US facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the New Jersey Department of Environmental Protection. For a plant of this scale, secondary treatment is typically required, and more advanced treatment may be mandated if the discharge affects sensitive waters. The designed capacity is 1.00 million gallons per day, indicating a substantial infrastructure investment. The plant's treated effluent is discharged into local waterways that ultimately drain to the Atlantic Ocean. The region's coastal ecology includes estuaries and marine habitats that support diverse aquatic life, including fish, shellfish, and migratory birds. Proper treatment is essential to protect water quality and recreational uses along the Jersey Shore.

The plant's discharge enters the Atlantic Ocean via local rivers and estuaries in Monmouth County. The coastal waters support a rich marine ecosystem, including important fisheries and habitats for species such as striped bass and blue crabs. Nutrient loading from wastewater can contribute to algal blooms and hypoxia, so effective treatment is critical for maintaining ecological balance.
