PLYMOUTH WWTF is a municipal wastewater treatment facility located in Amador County, California, serving a small population of 1,744 residents. The plant provides secondary treatment, a standard level for communities of this size in the United States, ensuring effective removal of organic matter and suspended solids before discharge. As a secondary treatment plant, PLYMOUTH WWTF operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges to surface waters. The plant's designed capacity of 416.39 units and current discharge volume of 416.40 units indicate it is operating near full capacity, typical for a facility serving a stable rural community. The plant's treated effluent is discharged into a local waterway within the Sacramento River basin, which ultimately drains to the Sacramento-San Joaquin Delta and San Francisco Bay. This watershed supports diverse aquatic life and provides critical habitat for migratory fish species, making proper treatment essential for downstream ecosystem health.

The plant discharges into a tributary of the Sacramento River, which flows through California's Central Valley into the Sacramento-San Joaquin Delta and finally San Francisco Bay. This watershed supports a variety of aquatic species, including salmon and steelhead trout, and is an important migratory corridor. The plant's secondary treatment helps protect water quality in this ecologically sensitive region.
