Chlorine Burnout Notice

Agua Special Utility District


Agua Special Utility District will be conducting a free chlorine burnout of its water distribution system as part of our regular maintenance program. The burnout will begin on Monday April 17, 2017. This event is expected to last for 14 days and end on Monday May 1, 2017.


Currently Agua Special Utility District uses chloramines for disinfection for the drinking water. Chloramines are created by combining chlorine and ammonia. During this free chlorine burn the disinfection process will be changed from chloramines to free chlorine. Free chlorine is a stronger and faster-acting disinfectant. Customer may notice open fire hydrants throughout the water distribution system during this period and possibly overflowing water storage towers. The fire hydrants will be opened to allow flushing of the system to help remove sediment from the pipes and distribute the change in disinfectant. Overflowing water storage towers further aid in the flushing process.


  • Possible Noticeable Effects: It is important to understand that during this temporary change there may be some discoloration or cloudiness in the water and possibly a slight chlorine odor or taste. If this is experienced you may want to run the water through the tap until it clears. Minor pressure fluctuations and small air pockets may also occur. Fire hydrant flushing should remove a majority of the color and odor, but some may reach customer lines during the process.
  • Is the Water Safe to Drink? Yes, the water is safe to drink throughout this process. Any odor and color issues will be nuisance only, which will subside as the flushing is completed. Discoloration in laundry is possible during this time. Cleaning additives are readily available at local stores to help prevent or remove any discoloration that may occur. Customers who use tap water for kidney dialysis at home should consult their doctor to advise them if any changes are necessary in their residual disinfectant neutralization procedures. Customers utilizing the water for aquariums should monitor both free and combined chlorine residuals.

Customers with any questions concerning the free chlorine burnout may call 956-585-2459 during normal business hours.
