Boulder Creek WWTF - Santa Cruz County, California Wastewater Treatment Plant

Boulder Creek WWTF is a municipal wastewater treatment facility located in Santa Cruz County, California, United States. The plant serves a small population of approximately 700 residents, reflecting its role in a rural or suburban community within the county. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater. With a designed capacity of 757.08 units and an actual discharge volume of 151.42 units, the facility operates well below its capacity, indicating potential for future growth or seasonal variability. As a U.S. plant, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the California State Water Resources Control Board, ensuring compliance with water quality standards. The treated effluent is discharged into a local water body, likely a tributary of the San Lorenzo River or directly into the river, which flows into Monterey Bay. This coastal watershed supports diverse aquatic life and is part of the larger California coastal ecosystem. The plant's operations are critical for protecting downstream water quality and the ecological health of Monterey Bay.

The plant discharges into a water body within the San Lorenzo River watershed, which flows into Monterey Bay, a part of the Pacific Ocean. This coastal region supports diverse marine life, including fish, seabirds, and marine mammals. The secondary treatment process helps reduce pollutants, protecting the bay's water quality and its role as a habitat for species such as steelhead trout and sea otters.
