HUNTINGTON STP Wastewater Treatment Plant, Lime, Oregon

HUNTINGTON STP is a municipal wastewater treatment plant located in Lime, Oregon, United States. The facility serves a small population of 520 residents and operates under secondary treatment standards, which is the minimum requirement for domestic wastewater under the US Clean Water Act. The plant has a designed capacity of 359.61 megaliters and reports an annual discharge volume of 189.27 megaliters. As a secondary treatment facility, it uses biological processes to remove organic matter and suspended solids. The plant is regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Oregon Department of Environmental Quality. The treated effluent is discharged into a local waterway that drains into the Snake River basin, ultimately reaching the Columbia River and the Pacific Ocean. The plant's location in eastern Oregon, away from the coast, reduces direct marine impact, but its discharge contributes to the overall water quality of the regional watershed.

The plant discharges into a tributary of the Snake River, which flows into the Columbia River and then the Pacific Ocean. The Snake River basin supports diverse aquatic life, including salmon and steelhead, and is an important ecological corridor. The plant's secondary treatment helps protect downstream water quality in this semi-arid region.
