The plant serves a population of about 27,991 residents, placing it in the medium-agglomeration category for US wastewater infrastructure. As part of New Jersey's wastewater network, the plant contributes to the state's efforts to manage water quality in the Delaware River Basin. Under the US Clean Water Act, plants of this scale are typically required to meet secondary treatment standards through National Pollutant Discharge Elimination System (NPDES) permits issued by the New Jersey Department of Environmental Protection. The designed capacity of 1.00 million gallons per day suggests the facility is sized to handle the community's wastewater flows. The plant's classification as a septic tank system indicates primary treatment with potential additional steps. The plant's treated effluent discharges into local waterways that ultimately drain to the Delaware Bay and the Atlantic Ocean. This watershed supports diverse aquatic life and is an important ecological corridor for migratory fish species. The facility's operations are critical for protecting downstream water quality in the Maurice River and Delaware Estuary.

The plant discharges into the Maurice River watershed, which flows into the Delaware Bay and then the Atlantic Ocean. This estuarine environment supports diverse aquatic life, including commercially important fish and shellfish species. The Delaware Bay is a critical stopover for migratory shorebirds and hosts extensive salt marshes that provide nursery habitat for juvenile fish. Protecting water quality in this system is essential for maintaining the ecological health of the bay and its fisheries.
