Starting on Monday, Dec. 31, and continuing through February 2022, Western Municipal Water District (Western) will begin flushing its water distribution system within the Murrieta service area. Water main flushing is the process of cleaning the interior of water pipes and removing any accumulated sediment by sending a rapid flow of water through the mains. The water is discharged through hydrants and travels into neighborhood gutters and storm drains, eventually making its way back into the groundwater basin or a nearby water reclamation facility. 

Flushing is a normal and necessary part of maintaining a safe and reliable drinking water supply as it helps to remove natural sediments that can accumulate in water mains.

Flushing will generally occur Monday through Thursday between 7 a.m. and 5 p.m. for most neighborhoods in Western’s Murrieta service area. During this time, water will remain safe to drink and no impacts to water services are expected. Customers may notice water in the street, and Western crews working in neighborhoods.
