Forest Meadows STP - Advanced Wastewater Treatment in Murphys, California

Forest Meadows STP (Sewage Treatment Plant) is located in Murphys, Calaveras County, California, serving a population of approximately 3,000 residents. The plant is situated inland in the Sierra Nevada foothills, providing wastewater treatment for this small community. The facility employs advanced treatment processes, exceeding the secondary treatment standard required by the US Clean Water Act. With a designed capacity of 715.44 m³/day and an average discharge volume of 681.37 m³/day, the plant operates at high utilization. As an advanced treatment plant, it likely incorporates nutrient removal or other tertiary processes to meet stringent water quality standards. The treated effluent is discharged into local waterways that drain into the Stanislaus River watershed, ultimately reaching the San Joaquin River and the Sacramento-San Joaquin Delta. This region supports diverse aquatic life and is part of California's critical water infrastructure, making advanced treatment important for protecting downstream ecosystems.

The plant discharges into the Stanislaus River basin, which flows into the San Joaquin River and eventually the Sacramento-San Joaquin Delta. This watershed supports sensitive aquatic habitats, including spawning grounds for Chinook salmon and steelhead trout. Advanced treatment helps minimize nutrient loading and protects water quality in this ecologically important delta system.
