Overview
Auke Bay STP is a secondary treatment plant in Juneau, Alaska, serving 300 people. It discharges treated wastewater near the coast, with a design capacity of 605.66 volume units.
Auke Bay STP is a municipal wastewater treatment facility located in Auke Bay, Juneau, Alaska. It serves a small population of 300 residents, reflecting the rural and coastal nature of the community. The plant is situated along Glacier Highway near the Auke Bay post office, providing essential sanitation services to this part of the Juneau area. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal wastewater. With a design capacity of 605.66 volume units and a current discharge volume of 492.10, the facility operates below its designed capacity. As a U.S. plant, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. The treated effluent is discharged into the coastal waters of Auke Bay, part of the larger Lynn Canal and the Inside Passage. This region supports diverse marine life, including salmon, herring, and marine mammals. The plant's proximity to the coast (within 10 km) means its discharge directly influences the nearshore marine environment, making proper treatment essential for ecosystem health.
Environmental context
Auke Bay STP discharges into Auke Bay, which connects to Lynn Canal, a major fjord in the Inside Passage of Southeast Alaska. This coastal ecosystem supports critical habitats for Pacific salmon, Dolly Varden char, and marine mammals such as humpback whales and harbor seals. The area is ecologically sensitive due to its role in nutrient cycling and as a migratory corridor for anadromous fish. Proper wastewater treatment is vital to prevent nutrient enrichment and pathogen contamination that could harm these resources.
