The Dexter Sanitary Service District is a municipal wastewater treatment facility located in Dexter, Lane County, Oregon. Serving a small population of 505 residents, the plant provides secondary treatment to meet Clean Water Act standards. Its designed capacity is 234.69 megaliters, with an annual discharge volume of 151.42 megaliters. As a secondary treatment plant, it utilizes biological processes to reduce organic matter and suspended solids. Under the U.S. EPA's National Pollutant Discharge Elimination System (NPDES), plants of this scale are required to meet effluent limits that protect water quality. The facility's operational status and treatment process details are consistent with typical small community systems in the Pacific Northwest. The plant discharges treated effluent into the Middle Fork Willamette River, a tributary of the Willamette River, which flows into the Columbia River and ultimately the Pacific Ocean. The receiving waters support diverse aquatic life, including salmonid species, and the plant's discharge is regulated to minimize environmental impact on this ecologically sensitive watershed.
