If you've noticed a stronger chlorine scent or taste in your tap water around Miami-Dade lately, there's a clear reason for it: the county's Water and Sewer Department is implementing a temporary shift in its disinfection process for the water supply.
The Miami-Dade Water and Sewer Department (WASD) announced that this change began on September 28 and will persist until October 11, 2026. During this period, the system is utilizing free chlorine instead of the usual chloramine blend at its treatment facilities.
Annual Routine for Over Four Decades
This is a planned operation that the county has been conducting annually for more than 40 years, in coordination with the Florida Department of Health in Miami-Dade and the Regulatory and Economic Resources Department.
Why the Stronger Chlorine Smell?
The temporary use of free chlorine is part of the system's cleaning and disinfection strategy. During this phase, some residents might detect a more pronounced chlorine odor or taste when turning on their faucets. WASD assures that this is a temporary condition and poses no adverse health effects.
Additionally, a prominent notice is maintained on the department's official site to inform residents about this temporary change, which will conclude on October 11.
Possible Cloudy Water and Pressure Changes
As part of this process, department workers may perform flushing and cleaning of pipes at various points in the network to ensure the treatment reaches the entire distribution system. As a result, some households might experience lower water pressure or notice cloudy water for short periods.
The county recommends letting the tap run for three to five minutes if the water appears cloudy, which should help clear it up. WASD describes this as a temporary and cosmetic effect of the process, emphasizing that it does not affect water quality.
Special Considerations for Dialysis Patients and Aquariums
The official advisory includes specific recommendations for certain situations. Dialysis patients are advised to consult their doctors about the temporary change in water treatment. Similarly, tropical fish owners and establishments with fish tanks, such as restaurants and stores, are encouraged to seek guidance from aquarium maintenance professionals.
These precautions are important because changes in chlorine concentration and type can be significant for those specific systems.
Not a Contamination Alert
While the change in water's smell, taste, or appearance might draw attention, the county stresses that this is part of regular maintenance and not a contamination alert or a directive to stop consuming water. The conversion specifically involves temporarily replacing the usual chloramine with free chlorine as the disinfection method. Once the scheduled period ends, the system will revert to its standard treatment process.
Context: Previous Water Notices in Miami-Dade
It is crucial not to confuse this routine measure with previous water availability issues that have affected South Florida. Earlier this year, in February, CiberCuba reported on a water shortage alert in Miami-Dade and other counties due to below-average rainfall and exceptionally low levels in the Biscayne Aquifer. That situation was related to drought and water availability, while the current process is a scheduled system disinfection operation.
Contact Information for Water Quality Concerns
Miami-Dade has provided contact numbers for its Laboratory Division for any water quality inquiries. Residents north of Southwest Eighth Street can call 786-552-4738. Those south of Southwest Eighth Street should dial 786-552-4181. The temporary change is set to continue until Sunday, October 11, when the annual treatment conversion is expected to conclude.
