Governor Newsom issued an executive order that eased drought emergency provisions. The order maintains the ban on wasteful water use. Customers are encouraged to use water wisely, only using what is needed and not one drop more. Rubio will allow (2) days per week outside irrigation. We would like to extend a special thanks to our customers who have reduced their water consumption and promoting water conservation as a way of life.

How is Water Treated

Our water goes through a multi-phase treatment process as we bring it from the source to you. 
  • Pre-Treatment and Disinfection: Chemical Addition Chlorine, Aluminum Sulfate (Alum), and Polymers are added to the water through a chemical injection mixer. These chemicals kill germs and improve the treatment process.
  • Coagulation & Flocculation: The water is mixed rapidly to distribute the chemicals and then sent to a floc/sedimentation basin. The chemicals bond to impurities in the water (a process called coagulation) and form large particles called floc.
  • Sedimentation: Floc particles settle at the bottom of the basin and are then removed to a sludge basin.
  • Filtration: Water then flows into the filter beds where layers of anthracite (coal), sand and gravel remove any remaining impurities in the water
