Eden Sewage Treatment Facility - Secondary Wastewater Plant in Eden, Idaho

Eden Sewage Treatment Facility is a municipal wastewater treatment plant located in Eden, Idaho, United States. The plant serves a small population of 405 residents in the rural community of Eden, situated in Jerome County. As a secondary treatment facility, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant has a designed capacity of 189.27 megaliters and currently treats approximately 68.14 megaliters of wastewater annually, indicating significant reserve capacity. Under the U.S. Clean Water Act, secondary treatment is the minimum standard for municipal wastewater plants, and the facility operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Idaho Department of Environmental Quality. The permit ensures compliance with effluent limits to protect water quality. The treated effluent is discharged to a local water body, likely a tributary of the Snake River, which flows into the Columbia River and eventually reaches the Pacific Ocean. The plant's location in the Snake River Plain, an agricultural region, underscores its role in protecting downstream water quality and supporting the local ecosystem.

The plant discharges into a local water body that drains into the Snake River, a major tributary of the Columbia River. The Snake River supports diverse aquatic life, including salmon and steelhead, and is an important migratory corridor. The surrounding agricultural region relies on clean water for irrigation, making the plant's secondary treatment essential for preventing nutrient pollution and maintaining downstream water quality.
