Culver STP - Secondary Wastewater Treatment Plant in Culver, Oregon

Culver STP is a municipal wastewater treatment plant located in Culver, Oregon, a small town in Jefferson County. The plant serves a population of approximately 850 residents, classifying it as a small-scale facility under typical regulatory frameworks. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The plant has a designed capacity of 340.69 megaliters per year and currently discharges 151.42 megaliters annually, indicating it operates well below its capacity. The treated effluent is discharged into a local water body, likely a tributary of the Deschutes River, which flows into the Columbia River and eventually the Pacific Ocean. The plant plays a key role in protecting water quality in the region, supporting aquatic life and downstream ecosystems.

The plant discharges into a local water body that is part of the Deschutes River basin, a major tributary of the Columbia River. The Deschutes River supports diverse aquatic life, including salmon and trout species, and is an important recreational and ecological resource in central Oregon. The Columbia River carries the outflow to the Pacific Ocean, making the plant's treatment performance relevant to downstream marine environments.
