BAL HARBOUR (September 21, 2026) – The Miami-Dade Water and Sewer Department (WASD) will conduct its annual Chlorine Conversion from September 28 through October 11. During this two-week period, WASD will temporarily change the method used to disinfect the County’s drinking water supply.
In coordination with the Florida Department of Health in Miami-Dade County and the Miami-Dade Department of Regulatory and Economic Resources (RER), WASD will use free chlorine instead of its standard combined chlorine (chloramine) during the water treatment process. Free chlorine is an effective method used to cleanse water distribution systems.
During the conversion, some customers may notice a temporary chlorine taste or smell. According to WASD, this temporary condition will not cause adverse health effects. Dialysis patients may wish to contact their doctor, while owners of tropical fish and businesses with fish-holding tanks are encouraged to consult an aquarium maintenance professional.
WASD crews will also flush water lines throughout Miami-Dade County to ensure the entire distribution system is included in the conversion. Residents may experience brief periods of lower-than-normal water pressure or cloudy water as a result.
