Water and Wastewater


The City owns and operates its own water production and distribution system.  Water is produced via a series of wells located throughout the City.  The City also owns two reservoir facilities to provide water storage capacity.  The City Council has adopted a policy that the City be able to produce two times the water demand.  This policy ensures that the City has sufficient redundancy in the event of a facility malfunction or shutdown for maintenance, upgrade or repair.


The City owns and operates its own wastewater collection and conveyance system and contracts with the City of Santa Rosa Subregional Water Reclamation System for wastewater treatment.  All of the City's wastewater is conveyed via pipeline to the City of Santa Rosa Wastewater Treatment Facility on Llano Road.
