Miller Kilpatrick WWTF - Secondary Wastewater Treatment in Santa Monica Mountains, California

Miller Kilpatrick WWTF is a wastewater treatment facility located in the unincorporated Santa Monica Mountains area of Los Angeles County, California. The plant serves a small population of 351 residents and operates with a designed capacity of 151.42 megaliters per year, currently processing 113.56 megaliters annually. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant operates under the regulatory framework of the United States Clean Water Act, administered by the California State Water Resources Control Board. Facilities of this scale are typically required to meet secondary treatment standards and obtain National Pollutant Discharge Elimination System (NPDES) permits. The proximity to the coast means that discharge regulations may include additional requirements to protect marine water quality. The treated effluent from the plant likely discharges into a local stream or drainage that flows to the Pacific Ocean via the Santa Monica Bay. The Santa Monica Bay is an ecologically important coastal ecosystem that supports diverse marine life, including fish, seabirds, and marine mammals. The bay is also a popular recreational area, making water quality protection a priority.

The plant's discharge ultimately reaches the Santa Monica Bay, part of the Southern California Bight in the Pacific Ocean. The bay supports a rich marine ecosystem, including kelp forests, rocky reefs, and sandy bottoms that provide habitat for fish, invertebrates, and seabirds. The proximity to the coast (within 10 km) means that nutrient and pollutant loads from the plant could affect nearshore water quality and marine life, particularly during dry weather when dilution is minimal.
