Golden State Water commends California customers for their exceptional water conservation efforts and encourages the community to continue using water resources wisely to support the state's drought recovery journey.

Following an extraordinarily dry winter, all residents must adopt water-efficient practices as part of California's Way of Life. On May 9, 2016, Governor Jerry Brown issued an Executive Order permanently prohibiting wasteful water practices, including:

  • Hosing off sidewalks, driveways and hardscaped areas
  • Washing vehicles without shut-off nozzle equipped hoses
  • Operating decorative fountains without water recirculation systems
  • Watering landscapes that cause excessive runoff
  • Irrigating within 48 hours after measurable rainfall
  • Watering ornamental turf in public street medians with potable water

Golden State Water appreciates customers' ongoing conservation commitment. For additional drought information and water conservation requirements in your area, please visit http://www.gswater.com/drought/ or call 1.800.999.4033.

Golden State Water Company (GSWC) - Southwest Municipal Water Company and CDC
  1. How should I investigate unexplained high water usage? You may have a hidden leaky toilet or faucet that's difficult to detect. Contact our office and we'll assist you in resolving the issue.
  2. What should I do if experiencing low water pressure? Inspect your meter and surrounding area for potential leaks, then contact our office to report the pressure issue at your location.
  3. Why does my water appear discolored? Recent repairs may have allowed air into the line, causing a milky appearance in your water.
  4. What chemicals are added to our municipal water? Only chemicals approved by the National Safety Foundation for treating drinking water are utilized in our system.
  5. My water tastes and smells unusual. Is it safe? All public water systems must maintain a minimum chlorine level of 0.2 mg/L (measured at the end of each line) per state regulations. Systems using chloramine must maintain 0.5 mg/L levels. Our disinfectant levels are tested daily to ensure safety.
  6. Why do particles appear when running hot water? Your water heater likely needs flushing. CAUTION: Most manufacturers recommend hiring a professional for this task. If attempting yourself, carefully read the owner's manual to prevent injury or damage.
  7. Why do I have an outstanding balance after sending payment? We may have received it after the due date or possibly not received it at all. Contact our office for assistance resolving the issue.
