Water System Flushing Frequently Asked Questions
Why does JBWD “flush” the water mains?
Flushing the water mains improves water quality by removing sediment that slowly builds up at the bottom of the water main over time. The sediment comes from internal corrosion of the water mains over many years.
How does the flushing work?
During the flushing process, water is forced through the water mains at a high speed and discharged through hydrants. The fast moving water scours and cleans the mains. We leave the hydrants open until the water runs clear.
How will I know when JBWD is cleaning the water mains in my neighborhood?
JBWD will inform residents before the day of the flushing by posting notices on our website and through a notice mailed to the property owners.
What should I do if my water is discolored after Western has flushed the water mains?
Water is sometimes discolored after water main cleaning, but this should not last long. In the event customers draw discolored water into the home, flush a cold tap only a few minutes, up to 15 minutes maximum. As a precaution, prior to using hot water, run the cold water tap for a few minutes to ensure discolored water is not drawn into the hot water tank.
What should I do if the water is still discolored after three to four hours?
Contact a JBWD Commissioner at 360-474-7171.
How long does it take to flush and clean the water mains on each street?
It takes about 30 minutes to 60 minutes to flush the water mains on each street.
Why can’t JBWD clean the water mains at night?
It’s safer for staff to work on the streets in daylight. Also, daylight provides better visibility to see when all the sediment has been flushed out and the water is running clear.
