Two Rivers Water Reclamation Authority WRA CS_STP - Monmouth Beach, New Jersey Wastewater Treatment Plant

Two Rivers Water Reclamation Authority WRA CS_STP is a municipal wastewater treatment facility located in Monmouth Beach, New Jersey, United States. It serves a population of approximately 86,861 people, classifying it as a medium-to-large agglomeration under typical US regulatory categories. The plant is situated in a coastal region, within 50 kilometers of the Atlantic Ocean, which influences its discharge requirements. As a US-based 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 plants of this scale, secondary treatment is the minimum standard, with potential additional requirements for nutrient removal to protect sensitive coastal waters. The designed capacity is reported as 1. The plant's treated effluent is discharged into local waterways that ultimately drain to the Atlantic Ocean via the Shrewsbury River or nearby coastal estuaries. This region supports diverse aquatic life, including fish and shellfish, and is an important migratory corridor for birds. The proximity to the coast necessitates careful management of nutrients and pathogens to prevent eutrophication and protect recreational waters.

The plant discharges into the Shrewsbury River watershed, which flows into the Atlantic Ocean via Sandy Hook Bay. This coastal ecosystem supports diverse marine life, including striped bass, bluefish, and winter flounder, and provides critical habitat for migratory shorebirds. Nutrient loading from wastewater can contribute to algal blooms and hypoxia in the bay, making advanced treatment important for maintaining water quality.
