Sewage that begins in your home or business eventually flows into a wastewater treatment plant. At the wastewater treatment plant, the wastewater is treated through various steps to remove solids and other contaminants until it has reached an environmental safe level to be suitable for disposal or reuse. The treated wastewater (effluent) that is not reclaimed is piped into the Los Angeles River, Santa Monica Bay, or Los Angeles Harbor to name a few.. The effluent meets or exceeds stringent state and federal water quality standards in order for it to be compatible with these aquatic environments. The Consolidated Sewer Maintenance District operates four treatment plants: Malibu Mesa Wastewater Reclamation Plant, Malibu Water Pollution Control Plant, Trancas Water Pollution Control Plant, Lake Hughes Community Wastewater Treatment Facility.
