SW Harbor Pol Abate Fac - Southwest Harbor, Maine Wastewater Treatment Plant

SW Harbor Pol Abate Fac is a municipal wastewater treatment plant located in Southwest Harbor, Maine, a coastal town in Hancock County. The plant serves a population of 1,854 and is part of the local infrastructure managing wastewater from the community. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 1,438.45 thousand cubic meters and an annual discharge volume of 529.96 thousand cubic meters, it operates well within its capacity. As a US facility, it is regulated under the Clean Water Act and likely holds an EPA NPDES permit issued by the Maine Department of Environmental Protection. The plant discharges treated effluent into local waters that ultimately drain into the Gulf of Maine, a biologically productive region of the Atlantic Ocean. The coastal environment supports diverse marine life, including fish, shellfish, and seabirds, making proper wastewater treatment essential for protecting water quality and ecosystem health.

The plant discharges into a watershed that flows to the Gulf of Maine, a nutrient-sensitive coastal ecosystem. The Gulf of Maine supports critical fisheries and marine habitats, including lobster and groundfish populations. Effective secondary treatment helps reduce nutrient loading and pathogen risks, safeguarding the ecological balance of the receiving waters and downstream marine environment.
