Murrieta Pipeline Maintenance - July 9 through August 31

Western Municipal Water District (Western) will be performing specialized pipeline maintenance throughout the Murrieta community in July and August. There are no planned disruptions to your water service during this project. Western’s crews and contractor will be working the following dates and times:

  • Monday, July 9 through Friday, July 13 from 10:00 p.m. to 6:00 a.m.
    Night work will take place in commercial business areas to avoid business interruptions
    near Madison Avenue (between Kalmia Street and Guava Street).
  • Monday through Friday, July 16 through August 21 from 8:00 a.m. to 4:00 p.m.
  • There may also be occasional work on select Saturdays.
  • Due to additional equipment maintenance, completion of the project has been pushed to Aug. 31. 
This pipeline maintenance project will use specialized filtration equipment to remove sediment buildup, which can cause discoloration of your water. Any sediment in the pipelines is due to naturally occurring minerals and is not a health concern. In the event you turn on your tap during or immediately after the maintenance and see discolored water, turn on an outdoor water faucet until the discoloration clears up (usually just a few minutes). Western’s team members will be available on site during the project. They will be happy to discuss our pipeline maintenance efforts with you. Western’s Water Quality Manager Albert Magallon will also be available to answer questions during the maintenance hours at 951.789.5119.

We do not anticipate traffic disruptions during the project. Electronic message boards and other signage will indicate when crews will be in your neighborhood. If you live near the commercial business areas where night work is taking place, you may see work lights or hear the sounds of general construction equipment. We are working closely with the contractor to minimize as much disruption as possible.

You can also contact Western’s Community Affairs Department via email at or 951.571.7285. We thank you for your patience and understanding as Western continues to take proactive measures to ensure reliable water service and water quality that continues to exceed state and federal standards.

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.
