What to avoid during water hydrant flushing

When we're flushing hydrants in your area, you should avoid:

• Using hot water. This could draw sediment into your tank.
• Running a tap that has a filter on it.
• Doing laundry, especially light colors.
• Letting children get too close to our work area.

Water discoloring and hydrant flushing

• Your water may discolor when we flush a nearby hydrant.
• It is safe to drink discolored water.
• This happens because the flushing process stirs up mineral deposits inside the pipe.
• We cannot predict if your water will discolor.

How long water will remain discolored

Discolored water should clear up in a few hours.

How to check if your water is clear

• Run the cold water tap located in the lowest point in your home.
• Do a check hourly.
• Run the water tap for two to three minutes each time.

Once the water runs clear

Flush the pipes in your home by running all cold water taps for a few minutes.
