Flushing Process

FlushingStafford County Utilities 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.

  • Message boards will be placed throughout each scheduled flushing area to let residents know flushing will be occurring in that neighborhood. 
  • 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 Utilities Department at (540) 658-8695.
