REEDSPORT STP - Reedsport, Oregon Wastewater Treatment Plant

REEDSPORT STP is a municipal wastewater treatment facility located in Reedsport, Douglas County, Oregon. Serving a population of about 5,253, the plant is situated near the coast on Port Dock Road, reflecting its role in managing wastewater for this small coastal community. The plant has a designed capacity of 1.00 million gallons per day. As a U.S. facility, it operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Oregon Department of Environmental Quality. For a community of this size, secondary treatment is typically required to meet federal standards. The plant's treated effluent is discharged into the Umpqua River estuary, which flows into the Pacific Ocean. This coastal location means the plant plays a key role in protecting the ecologically sensitive estuary and downstream marine environment from nutrient pollution and pathogens.

REEDSPORT STP discharges into the Umpqua River estuary, a vital coastal ecosystem that supports salmon, steelhead, and diverse aquatic life. The estuary serves as a nursery for juvenile fish and a migratory corridor for birds along the Pacific Flyway. The treated effluent ultimately reaches the Pacific Ocean, making nutrient and pathogen control critical for maintaining water quality in this sensitive coastal environment.
