The Wastewater Treatment Plant

The Wastewater Plant is a secondary treatment plant with trickling filters and ponds with river discharge. The purpose of the Plant is to collect and treat municipal sewage to such a degree that its discharge will not endanger public health nor degrade groundwater quality.

The degree of treatment has been set by discharge requirements established by the Central Coast Division of the Regional Water Quality Control Board in accordance with Public Law 92-500 and the State of California’s Comprehensive Water Management Plan. The Plant operates under California Regional Water Quality Control Board NPDES Permit No. CA0047953.
