Why are Hydrants Flushed?

  • By flushing, the District maintains a freshwater supply
  • To maintain the water quality in the mainlines by removing fine sediment that comes from our natural aquifer
  • To help the District to use less chlorine but still maintain small amounts in the water system as required by State and EPA regulations
  • To make sure the hydrants are in proper working condition for fire protection
  • To verify ample flow for fire fighting

Your water is safe to drink. Fire hydrant flushing is preventative maintenance.

What to Look Out For

  • A temporary drop in water pressure during testing periods
  • Occasional water discoloration after hydrant flushing
    • Run your cold water tap for a few minutes until the water clears
    • If it does not clear the first time, wait a few minutes and run the water again
  • Avoid washing clothes until the water clears

Hydrants can be painted to give firefighters and water operators important information. Usually, systems use the color of the bonnet to indicate the size of the water main.
