Miami-Dade Water and Sewer Department (WASD) - Chlorine Conversion

Miami-Dade Water and Sewer Department (WASD) will be conducting its annual Chlorine Conversion from September 9-22 this year. Coordinated in partnership with the Florida Department of Health in Miami-Dade County and the Miami-Dade Department of Regulatory and Economic Resources (RER), the department will temporarily change the method used to disinfect the drinking water supply at its water treatment plants during this two-week period. Specifically, free chlorine, instead of the standard combined chlorine (chloramine), will be used during the treatment process. Free chlorine is considered an effective method of cleansing water distribution systems.

At times during this period, some customers may notice a chlorine taste or smell. This temporary condition will not cause any adverse health effects. However, dialysis patients may want to contact their doctor, and the owners of tropical fish, managers of restaurants, and stores with fish-holding tanks are encouraged to seek advice from aquarium maintenance professionals.

WASD crews will be flushing water lines throughout the county during this two-week period to ensure that the entire distribution system is included. As a result, there may be intermittent, brief periods of lower-than-normal water pressure or instances of cloudy water. If you notice cloudy water, let the water run for three to five minutes until the water runs clear. This temporary, cosmetic issue does not impact water quality.

Should you have questions about your water quality, you can call the department’s Laboratory Division. Customers who live north of Southwest Eighth Street should call 786-552-4738. Those living south of Southwest Eighth Street should call 786-552-4181.
