1. What should I do when I see town crews flushing hydrants in my area?: If you see a town crew flushing hydrants while driving, PLEASE DRIVE CAREFULLY. You may also want to delay any laundry washing until the crew is finished and you have checked your water for discoloration. We also suggest that you turn off your refrigerator’s ice maker.

2. What should I do after the flushing?: If the tap water is used during flushing, it could come out full of sediment and discoloration. If you encounter discolored water, shut the water off and wait several minutes. After waiting, check for clarity by running cold water for a few minutes allowing new water to work its way into your pipes. If not, wait a few more minutes and check again. We recommend using a tub or outside faucet to clear the line. In some cases, you may experience slight discoloration for a few hours. This discoloration only affects the appearance of the water; it does not affect the taste or water quality.

3. What should I do if my water pressure or volume seems low after flushing?: Check your faucet and washer screens for trapped debris.

4. Why does the water look funny 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 twenty-four (24) hours, please contact our Water Department at 252-449-4210.

5. Is it okay to drink the sediment-laden or discolored water during temporary disturbance events?: It is recommended that water users wait until the water has cleared before using it for potable (drinking) purposes.
