Cove Orchard Sewer Service Dist Wastewater Treatment Plant, Oregon

Cove Orchard Sewer Service Dist is a wastewater treatment plant located in Cove Orchard, Oregon, United States. It serves a small population of 118 residents, reflecting its role as a local municipal facility in Yamhill County. The plant provides secondary treatment, which is the standard level required under the US Clean Water Act for municipal wastewater. Its designed capacity matches the current discharge volume of 75.71 units, indicating full utilization. As a small facility, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which regulates discharges to surface waters. The plant discharges treated effluent into local waterways that eventually drain to the Pacific Ocean via the Willamette River system. Its inland location, more than 50 km from the coast, reduces direct marine impact. The facility plays a key role in protecting local water quality in the Yamhill River watershed.

The plant discharges into the Yamhill River watershed, which flows into the Willamette River and ultimately the Columbia River before reaching the Pacific Ocean. This inland system supports diverse aquatic life, including salmonid species, and is important for regional water quality. The plant's secondary treatment helps reduce nutrient and pollutant loads to these sensitive waterways.
