Murrieta Water System Cleaning

To continue providing the highest quality water to our customer's, Western will be conducting water main flushing in Murrieta beginning Monday, May 3 through Monday, May 17. Work will take place during normal business hours Monday through Friday from 7 a.m. to 5 p.m.

Water will remain safe to drink and no disruptions to your water services are anticipated. 

During the work, you may notice Western trucks parked on streets and crews working in your neighborhood. Western will be using the NO-DES (Neutral Output Discharge Elimination System) flushing and filtration system, a new water-efficient technology that flushes system pipelines while keeping water contained within the system, without losing a single drop!

For more information on the flushing process and customer impacts, review our list of Frequently Asked Questions below.
