City of Jacksonville issued the following announcement on May. 14.
The Jacksonville Water Department along with the Jacksonville Fire Department will begin flushing fire hydrants on May 17, 2021. The process starts each year and continues until each hydrant has been flushed. The purpose is to ensure the hydrants are in good working order. Occasionally, residents may experience slight water discoloration and some loss of pressure when the fire hydrants are being flushed in their area.
During the period of discoloration we suggest not to do light colored laundry.
The water quality is not affected by the process and the pressure is restored once the flushing is complete.
If discoloration is experienced, it should dissipate within a few hours.
Please call 479-4660 if you have any questions.
