North Jay WWTF is a municipal wastewater treatment facility located at 32 Jerry Street in North Jay, Maine, serving a population of 404 residents. The plant is part of the wastewater infrastructure for the town of Jay in Franklin County, operating under the regulatory framework of the US Clean Water Act. The plant provides secondary treatment, which is the standard level required by the US EPA for municipal wastewater facilities. It has a designed capacity of 227.12 thousand cubic meters per year and discharges approximately 227.13 thousand cubic meters of treated effluent annually. As a small-scale facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. The treated wastewater from North Jay WWTF is discharged into a local receiving water body, ultimately draining into the Androscoggin River watershed. The Androscoggin River flows through Maine and New Hampshire before emptying into the Atlantic Ocean via Merrymeeting Bay. The plant's operations help maintain water quality in this ecologically important river system, which supports diverse aquatic life and recreational uses.

The North Jay WWTF discharges into a tributary of the Androscoggin River, which flows southward through Maine and New Hampshire to Merrymeeting Bay and the Gulf of Maine. The Androscoggin River watershed supports a variety of fish species, including Atlantic salmon and brook trout, and is an important migratory corridor. The plant's secondary treatment helps reduce nutrient and organic loading, protecting downstream water quality in this sensitive riverine ecosystem.
