LEBANON STP Wastewater Treatment Plant, Lebanon, Oregon

LEBANON STP is a municipal wastewater treatment facility located in Lebanon, Linn County, Oregon. Serving a population of around 11,030, the plant is part of the region's infrastructure for managing domestic wastewater from the community. As a plant in the United States, LEBANON STP operates under the Clean Water Act, with discharge permits issued by the Oregon Department of Environmental Quality. The treated effluent from LEBANON STP is discharged into a receiving water body that ultimately flows into the South Santiam River, a tributary of the Willamette River. The Willamette River drains into the Columbia River, which reaches the Pacific Ocean. The plant plays a role in protecting water quality in this important Pacific Northwest watershed.

The treated effluent from LEBANON STP enters a local watercourse that feeds into the South Santiam River, part of the Willamette River basin. The Willamette River flows north to join the Columbia River, which empties into the Pacific Ocean. This watershed supports diverse aquatic life, including salmon and steelhead, and is ecologically sensitive to nutrient loading and pollutants.
