Hydrant flushing is an important tool used by North Port Utilities to keep our water quality at the highest levels.  Periodically you will see Utilities personnel releasing water from fire hydrants. Hydrant flushing is necessary to test the hydrants to make sure adequate flow and pressure is available. Flushing is also done to remove sediment from the pipes in order to maintain water clarity and quality in the distribution pipes.  There are several possible times when you may see the hydrants being flushed in your neighborhood:

  • Routine maintenance flushing
  • Quarterly dead end main flushing
  • Fire hydrant testing, servicing and repair
  • Post-main break flushing
  • Flushing occurs more frequently during summer months to retain disinfectant residual due to high temperatures

There are also many reasons to do hydrant flushing:

  • To prevent disinfection by-product formation
  • To prevent chlorine residual decay
  • To prevent biological nitrification
  • To prevent total coliform formation
  • To prevent taste and odor complaints

After flushing, your water is safe to drink. Occasionally, water becomes discolored after hydrant flushing. If this happens, run your cold water tap for a few minutes until the water clears. If it doesn't clear the first time, wait a few minutes and run the water again.

North Port Utilities strongly advocates water conservation and requests that our customers and all residents of North Port practice water conservation principles.  To many, hydrant flushing appears to be a huge waste of potable water.  The safety of the water we deliver is our number one consideration, so hydrant flushing is a priority over water conservation.  But we try to tie water conservation and hydrant flushing together.  Whenever possible we will direct the water being flushed onto yards and into ponds used for irrigation.  Whenever possible the Utilities Department coordinates with other City departments that may need water and arrange for them to use the water that will be flushed.  But again, our need to keep the water quality safe comes first.
