ALERT: Message to all our Shareholders

Dear Shareholders, In the wake of the devastating wildfires, we want to take a moment to express our deepest gratitude for your patience, resilience, and unwavering strength. The past few months have tested us all in ways we never could have imagined. Each day, we wake up to navigate a new reality shaped by loss, uncertainty, and the immense challenge of rebuilding. Rubio Cañon Land and Water Association, has been working tirelessly to restore full water service to everyone who has been able to return home. For those still rebuilding, please remember that we are here and ready to assist you when you return. The firestorms that swept through Altadena placed extraordinary strain on our water systems and the agencies that oversee them in ways no one could have fully anticipated. As smaller, community-owned water providers, we faced these challenges with limited resources, yet we remained committed to restoring safe, reliable water as quickly as possible. Through our team's dedication and the collective efforts of our community, we made steady progress, keeping pace with some of the largest utilities as they also worked on their post-fire recovery efforts. Recovery is ongoing, and we know that state regulators are adapting to these unprecedented challenges just as we are. We appreciate their collaboration and commitment to ensuring public health and safety along every step of the way. Most of all, we appreciate you—our community. Your patience, support, and resilience inspire us every day. It is our honor to serve you, and we will continue standing with you as we rebuild together. With gratitude and commitment, Rubio Cañon Land and Water Lisa Yamashita-Lopez General Manager

How is Water Treated

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
