Flushing and Waterline Maintenance

NOTICE: Temporary Change in Your Water's Disinfectant and Annual Water Flushing

Schedule: Beginning on March 15, 2021 and continuing through May 31, 2021, Stafford County will begin a system-wide-flush to ensure a high level of disinfection of water mains. Crews will work Monday-Friday from 7:30 a.m. to 3:30 p.m. (excluding holidays). 

Click on the maps below to see when crews will be flushing in your neighborhood.

What to Expect: Stafford County will temporarily change the treatment process by using "free chlorine" in place of the combined chlorines that are used as the primary disinfectant throughout the year. While the flushing process will continue through May 31, 2021, Stafford County will return to combined chlorine on April 16, 2021. 

You may notice a slight chlorine taste and odor in your drinking water while free chlorine is utilized. This flushing process may also affect owners/operators of fish tanks, laundromats and other water-dependent operations. During the flushing process, customers may also experience a short-term decrease in water pressure or discoloration of water. If this occurs, customers are advised to run cold water through their faucets for a few minutes until the water runs clear. 

Hydrant Flushing

Stafford County Public Works’ Water Department routinely conducts Flushing throughout Stafford County each year. 

The hydrant flushing program is very important to the maintenance of the County's water distribution system. Flushing allows Stafford County to continue to deliver the highest quality water possible to our customers and ensures adequate water flow is available to firefighters, residents and businesses. The flushing process is a controlled procedure that draws water more forcefully through the distribution system removing the sediment, rust, debris or stagnant water that naturally accumulates in the water mains.

2021 Water Main Flushing Program

DATES:August 31, 2021 - November 20, 2021
  • Improves water quality in the distribution system 
  •  Verifies the proper operation of fire hydrants and valves 
  •  Helps find weaknesses in the water system 
  •  Checks for closed valves and weak flows in the water mains 

  • Message boards will be placed throughout each scheduled flushing area to let residents know flushing will be occurring in that neighborhood. The message boards will be set out at least 12 hours before the process begins and will remain there until flushing is complete for that area .
  • Utility trucks will be parked in front of the hydrants and crews will control and monitor the entire flushing process. Each hydrant takes approximately one hour to flush.
  • During the flushing process, customers may experience a short-term decrease in water pressure or discoloration of water. If you encounter such conditions, run your COLD water for five minutes.

If you experience discoloration for a prolonged time or if you experience a significant loss of water pressure after flushing has occurred, please call our Department of Public Works at (540) 658-8695. 


• If possible, limit your water use

• Wait until flushing has subsided in your area then run the cold water tap until the water runs clear

​​• If you have a water softener and are experiencing discolored water, place the unit into regeneration or cleaning mode after hydrant flushing is completed in your area

​​​• Remember rust colored water is safe, but it may stain laundry. If this happens, keep clothes wet and treat them with stain remover

​​• Check the faucet screens for trapped particles.
