Public Works > Water > Hydrant Flushing

• Cross Connection Information

We schedule our flushing program during our wetter months when water supplies are more plentiful. We flush from larger mains first, then move to smaller mains. The flushing route is carefully planned, and valves are opened and closed to control the direction of the water flow.

What should I do when I see City crews flushing hydrants in my area?

If you see a crew flushing a hydrant on your street, avoid running tap water, your washing machine or the dishwasher until the flushing is done. If you see hydrant flushing crews working in the area, please drive carefully and treat them like any other construction crew. DRIVE SAFELY.

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 the 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. 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.
Avoid washing laundry during scheduled flushing times. Wait until the water is clear from the tap, then wash a load of dark clothes first.
If pressure or volume seems low, check your faucet screens for trapped debris.

Why does my 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 for a few minutes.
