Water Main Flushing

About Water Main Flushing

Water main flushing is a necessary program for water agencies to keep up their infrastructure and ensure high-quality water. The traditional procedure includes opening up fire hydrants to scour and remove the buildup in pipes that may cause discolored water. As water flows at high velocities through the mains, encrustations, biofilm and fine sediment are dislodged. The resulting discolored water leaves the distribution system through the open fire hydrants, runs down the street and out to the sewer or storm drain systems. 

District customers may temporarily experience discolored water during water main flushing. Water users are advised not to be alarmed if water looks rusty as this discolored water is caused by sediments being stirred up within the water mains. If you experience any of these changes or if you see some cloudiness or rust color in your water, we recommend you flush the pipes of your home. Flushing of your home's pipes is accomplished by opening your front outside hose bib until it runs clear. If the water does not clear the first time, wait a few minutes and run the water again. It is also advised that you make sure your water is clear before doing laundry or other projects for which discolored water could cause problems. It is important to not run hot water if you notice it is discolored, as the discolored water can be drawn into the hot water tank.
