The REPUBLIC S_T FACILITY is a municipal wastewater treatment plant located in Ferry County, Washington, United States. It serves a population of 1,220 and is classified as a small agglomeration under US regulatory frameworks. The plant provides secondary treatment, which is the minimum standard required by the US Clean Water Act for municipal wastewater facilities. With a designed capacity of 605.66 thousand cubic meters per year and an annual discharge volume of 264.98 thousand cubic meters, the plant operates well within its capacity. As a US facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Washington State Department of Ecology. The plant's treated effluent is discharged into local waterways that drain into the Columbia River basin, ultimately reaching the Pacific Ocean. The facility plays a key role in protecting water quality in the region's rural watershed, supporting aquatic life and downstream ecosystems.

The plant discharges into tributaries of the Columbia River, which flows through Washington and Oregon before reaching the Pacific Ocean. The Columbia River basin supports diverse aquatic species, including salmon and steelhead, and is ecologically sensitive to nutrient and pollutant loads. The plant's secondary treatment helps reduce organic matter and suspended solids, mitigating impacts on downstream water quality.
