WELCOME TO THE WASTEWATER DIVISION
The Wastewater Treatment Plant
The City's 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 Regional Water Quality Control Board. The Plant operates under NPDES Permit No. CA0047953.
