Week 2 Water Main Flushing FAQ
How does the City flush water mains?
Water mains are flushed in a specific sequence - opening certain hydrants along a line in a systematic method. It can take anywhere from 30 to 60 minutes to flush a main.
Water coming out of the hydrant is flowing at a very high rate of speed and pressure - remember safety first! Stay out of the way to prevent injury to yourself or damage to property.
