Jordan Valley STP is a municipal wastewater treatment facility located in Jordan Valley, Oregon, a small community in Malheur County. The plant serves a population of approximately 250 residents, reflecting the rural character of the area. As a secondary treatment plant, it provides biological treatment to reduce organic pollutants and suspended solids before discharge. The plant operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all wastewater discharges. For small communities like Jordan Valley, secondary treatment is the standard requirement, ensuring compliance with federal water quality standards. The plant's designed capacity of 177.91 megaliters per year indicates it has room to accommodate future growth. The treated effluent from Jordan Valley STP is discharged into the local watershed, which ultimately drains into the Snake River basin. The Snake River flows through Idaho and Washington before joining the Columbia River, which empties into the Pacific Ocean. This connection highlights the plant's role in protecting downstream water quality in a region known for agriculture and wildlife habitat.

Jordan Valley STP discharges into the Malheur River watershed, a tributary of the Snake River. The Snake River flows through the high desert of eastern Oregon and Idaho, supporting irrigated agriculture and diverse aquatic life. Downstream, the Snake River joins the Columbia River, which is a critical migration corridor for salmon and steelhead. The plant's secondary treatment helps protect these waters from nutrient pollution and pathogens, maintaining ecological balance in a semi-arid region.
