January Pipeline Maintenance Shutdown - January 23 - January 29, 2019

To provide you with the reliable service that you have come to expect, Western’s imported water wholesaler, the Metropolitan Water District (MWD), will be taking its primary pipeline out of service for routine maintenance January 23 – 29, 2019. During this time, Western will not receive any water from MWD. Western will meet 100 percent of your water needs entirely through storage and through smaller connections with neighboring agencies.

To ensure there is enough water for our customers and to keep storage at adequate levels in the event of an emergency,
Western requests:

  • All industrial- and irrigation-related businesses curtail usage
  • All homeowners suspend all outdoor water use starting on
    January 21 through the end of the shutdown.

We thank you very much for your cooperation and assistance. Please check our social media feeds or here for updates , or feel free to contact staff at 951.571.7100 and ask for shutdown information.

2011 Hazard Mitigation

Western Municipal Water District is in the process of updating its Hazard Mitigation Plan. The Federal Emergency Management Agency (FEMA) requires that all public agencies have a plan to mitigate natural and man-made hazard impacts on its daily operations. The term "Hazard Mitigation" describes actions that can help reduce or eliminate long-term risks caused by natural hazards, or disaster, such as floods, wildfires, high winds and earthquakes as well as man-made events such as power outages, civil unrest, nuclear meltdown or even a pandemic illness in the region. If you would like to learn more about Western’s Hazard Mitigation Plan, or have comments, please contact Administrative Services at 951.571.7100.
