JONESPORT STP - Jonesport, Maine Wastewater Treatment Plant

JONESPORT STP is a wastewater treatment plant located in Jonesport, Washington County, Maine, United States. The plant is projected to serve a small population of 400 residents, reflecting the rural character of this coastal community in eastern Maine. The plant is designed with secondary treatment capacity, which is the standard minimum under the U.S. Clean Water Act for municipal wastewater facilities. With a designed capacity of 264.98 thousand cubic meters per year and a matching discharge volume, the plant is sized to handle the local wastewater load. As a projected facility, it represents planned infrastructure to meet community needs. The plant's location within 10 km of the coast means its treated effluent will ultimately reach the Gulf of Maine, a biologically productive marine ecosystem. The discharge supports the health of local estuaries and coastal waters, which are important for fisheries and marine biodiversity in the region.

The treated effluent from JONESPORT STP discharges into the coastal waters of the Gulf of Maine, a nutrient-rich sea that supports diverse marine life including groundfish, lobster, and seabirds. The local watershed drains through small coastal streams and estuaries that provide critical habitat for migratory fish and shellfish. Protecting water quality in this area is essential for maintaining the ecological integrity of the Gulf of Maine ecosystem.
