The Bellevue WW Treatment Facility is a municipal wastewater treatment plant located in Blaine County, Idaho, United States. It serves a population of 2,229, classifying it as a small community system under U.S. EPA regulations. The plant is situated inland, far from coastal waters, and operates under the Clean Water Act framework. The facility employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 1,892.70 thousand cubic meters per year and an actual discharge volume of 870.65, the plant operates below its capacity, indicating room for future growth. As a small system, it is subject to EPA's NPDES permitting requirements, ensuring compliance with water quality standards. The treated effluent is discharged into local waterways that drain into the Big Wood River watershed, part of the Snake River basin, which ultimately flows to the Columbia River and the Pacific Ocean. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the region's arid environment.

The plant discharges into the Big Wood River watershed, which feeds into the Snake River and eventually the Columbia River, reaching the Pacific Ocean. The region's semi-arid climate makes water quality critical for local agriculture and wildlife. Advanced treatment reduces nutrient loading, protecting downstream habitats and supporting diverse aquatic life in the Snake River basin.
