Serving a population of about 4,870, the plant is part of the region's infrastructure for managing domestic wastewater from this small community in the Willamette Valley. Under the U.S. Clean Water Act, wastewater treatment plants of this scale are typically required to provide secondary treatment through National Pollutant Discharge Elimination System (NPDES) permits issued by the Oregon Department of Environmental Quality. These permits set effluent limits to protect water quality in receiving water bodies. The plant's treated effluent discharges into a local waterway that ultimately flows into the Willamette River, a major tributary of the Columbia River. The Willamette River supports diverse aquatic life and is an important ecological corridor in the Pacific Northwest.
