Why does the water look discolored after hydrant flushing?

When a hydrant is opened, there will always be temporary incidences of discolored water containing fine sediment particles. There is no health hazard associated with discolored water. Allow a few hours for discoloration to dissipate. To verify the water has settled, allow your cold water tap to run a few minutes. If the discoloration persists for more than 24 hours, please contact our Water Division at 973-535-7951.
