TWIN RIVERS WATER SYSTEM
SYSTEM FLUSHING AND TEMPORARY MODIFICATIONS OF DISINFECTION TREATMENT PROCESS
Dear FGUA Customer:
Beginning Tuesday, July 5, 2022, the Florida Governmental Utility Authority (FGUA) will be temporarily changing its
disinfection process for the drinking water in your community for routine maintenance of water quality in the
The FGUA conducts system flushing at this time as part of its prudent utility practice. Flushing will remove sediment
that may be present within the distribution system piping. A buildup of sediment in water pipes may lead to odor
and discoloration in some water systems and occurs as disinfectants that are used to treat the water subsides.
When the FGUA temporarily changes the disinfection process, your water will be disinfected with free chlorine rather
than combined chlorine/ammonia (chloramines). This conversion to free chlorine (which is a stronger, faster-acting
disinfectant) from chloramines (which is a longer-lasting disinfectant) allows the FGUA to perform a water distribution
system purge as recommended by the Department of Environmental Protection for water utilities using chloramines
as their primary disinfectant. This temporary change in disinfection will last 21 days and end on the morning of July
This process will not cause adverse health effects. However, during this period, you may notice some discoloration
and or cloudiness in your water. You may also find air pockets in the system. The discoloration and air are harmless.
If you do experience this, you may want to run water through the tap until it runs clear. Some areas may also experience
a temporary fluctuation in water pressure or a slight increase in the taste and odor of chlorine.
Discoloration in laundry can occur. You may wish to purchase and use a cleaning additive available at local grocery
or home improvement stores. Including this while washing should prevent (or remove) any discoloration that may
Customers who use tap water for kidney dialysis at home should properly monitor their process for complete
neutralization of disinfectant residual and should contact their doctor for more information.
To condition tap water for use in an aquarium, de-chlorinating products should be used that neutralize both combined
and free chlorine. The water should be tested with a kit that can measure both combined and free chlorine.
Please call the FGUA at 877-657-8889 with any questions or for additional information on this process. The FGUA
appreciates your patience while this temporary change occurs to maintain clean and clear water in your system
