BOARDMAN STP is a municipal wastewater treatment facility located in Boardman, Oregon, a small city in Morrow County. The plant serves a population of approximately 3,220 residents, reflecting its role as a key infrastructure component for the local community. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant operates under the regulatory framework of the U.S. Clean Water Act, administered by the Oregon Department of Environmental Quality. For a facility of this scale, secondary treatment is the standard requirement, ensuring compliance with National Pollutant Discharge Elimination System (NPDES) permits. The plant's designed capacity of 1,514.16 units suggests it has room for future growth, with current discharge volumes at 870.65 units. The treated effluent from BOARDMAN STP is discharged into a local waterway that ultimately drains to the Columbia River, a major Pacific Northwest river system. The Columbia River supports diverse aquatic life, including salmon runs, and flows into the Pacific Ocean. The plant's operations are critical for protecting downstream water quality and the ecological health of the river basin.

The treated effluent from BOARDMAN STP enters a local tributary that flows into the Columbia River, one of the largest rivers in North America. The Columbia River basin supports a wide range of aquatic species, including endangered salmon and steelhead trout. Downstream, the river discharges into the Pacific Ocean, making the plant's secondary treatment essential for minimizing nutrient and pollutant loads that could impact both freshwater and marine ecosystems.
