BUCKSPORT WWTP is a municipal wastewater treatment plant located at 205 Route 1 in Bucksport, Hancock County, Maine. The facility serves a population of approximately 3,656 residents and operates as a primary treatment plant, providing basic physical settling and skimming processes. Its designed capacity is 1,741.28 million gallons per year, with an actual discharge volume of 946.35 million gallons per year. As a primary treatment plant, BUCKSPORT WWTP provides preliminary solids removal and sedimentation. Under the U.S. Clean Water Act, municipal plants are typically required to achieve secondary treatment levels, though primary treatment may be permitted for certain coastal discharges with appropriate environmental waivers. The plant's discharge volume indicates it operates below its designed capacity. The plant's treated effluent is discharged into the Penobscot River estuary, which flows into Penobscot Bay and ultimately the Gulf of Maine. This coastal region supports diverse marine life, including commercially important fish and shellfish species. The discharge point is within 10 km of the Atlantic coast, making the plant's operations relevant to coastal water quality and marine ecosystem health.

The plant discharges into the Penobscot River estuary, a major tidal river that drains into Penobscot Bay and the Gulf of Maine. This watershed supports critical habitats for Atlantic salmon, alewife, and other diadromous fish species. The coastal location means effluent can influence nearshore water quality, particularly in the context of nutrient loading and pathogen control in shellfish growing areas.
