Narragansett Scarborough Wastewater Treatment Plant, Narragansett, Rhode Island

The Narragansett Scarborough wastewater treatment plant is located in Narragansett, Rhode Island, along Ocean Road near Point Judith. It serves a population of approximately 7,379 residents in the South County region, operating as part of the municipal wastewater infrastructure for the coastal community. As a U.S. facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Rhode Island Department of Environmental Management. For a plant of this scale, secondary treatment is typically required, with additional nutrient removal expected in sensitive coastal areas to protect marine water quality. The plant discharges treated effluent into the Atlantic Ocean via the local coastal watershed. The receiving waters include the Point Judith Pond and the surrounding salt ponds, which are ecologically important habitats for fish, shellfish, and migratory birds. The area supports diverse aquatic life and is part of a larger estuarine system that drains into Rhode Island Sound.

The plant discharges into the Atlantic Ocean through the Point Judith coastal watershed, which includes the Point Judith Pond and adjacent salt ponds. These waters support diverse aquatic life, including shellfish beds and finfish, and are part of a larger estuarine system that drains into Rhode Island Sound. The coastal environment is sensitive to nutrient loading, making effective treatment critical for maintaining water quality and ecosystem health.
