On Tap: Fairfax Water’s Annual Flush

Each spring, Fairfax Water flushes its water mains by opening fire hydrants and allowing them to flow freely for a short period of time. For the majority of customers, this flush is underway now through June. You will likely notice Fairfax Water personnel in your neighborhood.


Water is Safe to Drink

You may notice a chlorine taste and odor in your drinking water while free chlorine is washing its way through. Flushing also may result in temporary discoloration and the presence of sediment in your water. These conditions are not harmful and should be of very short duration. If you are especially sensitive to the taste and odor of chlorine, try keeping an open container of drinking water in your refrigerator, but remember – drinking water has a shelf life! Change out the water in your refrigerated container weekly.


How to Recognize a Fairfax Water Employee in Your Neighborhood

You will be able to recognize Fairfax Water employees by a number of identifiers:

  • Employees will be driving vehicles identified with the Fairfax Water logo.
  • Employees will be displaying a sign that identifies the employee as part of the Fairfax Water flushing program.
  • Employees will be wearing uniforms with the same Fairfax Water logo.

If you have questions about this program or the work being conducted in your area, call Fairfax Water (which is a separate authority from Fairfax County Government) any time of the day or night at 703-698-5613, TTY 711.
