McCammon S_T Facility - Secondary Wastewater Treatment Plant in McCammon, Idaho

The McCammon S_T Facility is a municipal wastewater treatment plant located on North Front Street in McCammon, Bannock County, Idaho. It serves a population of approximately 809 residents, classifying it as a small community system 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 681.37 thousand gallons per day and an average discharge volume of 605.67 thousand gallons per day, the plant operates at a high utilization rate, indicating consistent demand from the local community. The treated effluent is discharged into the Portneuf River watershed, which flows into the Snake River and ultimately the Columbia River system. This downstream connection to the Columbia River basin highlights the plant's role in protecting water quality in a major Pacific Northwest drainage system that supports diverse aquatic life and regional agriculture.

The plant discharges into the Portneuf River, a tributary of the Snake River, which flows into the Columbia River and eventually the Pacific Ocean. The Portneuf River supports cold-water fisheries and is part of a watershed that provides habitat for native trout species. The plant's secondary treatment helps reduce organic pollutants and suspended solids, protecting downstream water quality in this semi-arid region of southeastern Idaho.
