The Brooks Sewage Treatment Plant is a municipal wastewater facility located in Brooks, Oregon, serving a small population of approximately 398 residents. The plant is situated in Marion County, within the Willamette Valley region, and operates as part of the local infrastructure managed by the community. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal wastewater facilities. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The plant has a designed capacity of 832.79 and currently discharges 681.37, indicating it operates below its maximum capacity. The treated effluent from the plant is discharged into a local water body that ultimately drains into the Willamette River, a major tributary of the Columbia River. The Willamette River supports diverse aquatic life and is an important resource for recreation and agriculture in the region. The plant's operations are regulated under the National Pollutant Discharge Elimination System (NPDES) permit program to ensure compliance with water quality standards.

The Brooks Sewage Treatment Plant discharges into a receiving water body that flows into the Willamette River, which then joins the Columbia River before reaching the Pacific Ocean. The Willamette River basin supports a variety of fish species, including salmon and steelhead, and is ecologically sensitive to nutrient loading and pollutants. The plant's secondary treatment helps reduce organic matter and suspended solids, protecting downstream water quality and aquatic habitats.
