ELKTON STP - Secondary Wastewater Treatment Plant in Elkton, Oregon

ELKTON STP is a municipal wastewater treatment facility located in Elkton, Douglas County, Oregon, United States. The plant serves a small population of 180 residents, reflecting the rural character of the community. It operates under the regulatory framework of the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all point source discharges. The plant provides secondary treatment, a standard level that removes biodegradable organic matter and suspended solids. With a designed capacity of 105.99 units and an average daily discharge of 75.71 units, the facility operates below its maximum capacity. Secondary treatment typically involves biological processes such as activated sludge or trickling filters. The treated effluent is discharged into a local water body, likely a tributary of the Umpqua River, which flows into the Pacific Ocean. The plant's inland location, over 50 km from the coast, reduces direct marine impact. The Umpqua River basin supports diverse aquatic life, including salmon and steelhead, making water quality protection important.

The plant discharges into a local water body that is part of the Umpqua River watershed, which drains into the Pacific Ocean. The Umpqua River supports ecologically significant species such as Chinook salmon and steelhead trout, which rely on clean water for spawning and migration. The plant's secondary treatment helps reduce nutrient and pollutant loads, protecting downstream habitats.
