Miami-Dade Water and Sewer Department Begins Annual Chlorine Conversion Sept. 28, 2026

The Miami-Dade Water and Sewer Department (WASD) will conduct its annual chlorine conversion starting next week. This routine maintenance process, scheduled from September 28, 2026, through October 11, 2026, ensures the continued safety and quality of the county's drinking water.

During this two-week period, WASD will temporarily switch its water disinfection method from combined chlorine to free chlorine. This temporary change helps maintain the distribution system and disinfect the drinking water effectively. Residents will continue to receive water that is safe for consumption throughout the conversion.

Some residents may notice a slight chlorine taste or odor in their tap water during this time. While the water remains safe, those with specific health conditions or home aquariums should take appropriate precautions. WASD advises these residents to consult with their healthcare providers or aquarium specialists regarding any necessary adjustments.

The annual chlorine conversion is a standard practice for water utilities. It helps prevent the buildup of certain microorganisms within the water distribution pipes, ensuring long-term water quality. This process is a proactive measure to safeguard public health and maintain the integrity of the water system.

The conversion will conclude on October 11, 2026, after which WASD will revert to its standard combined chlorine disinfection method. Residents with further questions can contact the Miami-Dade Water and Sewer Department directly.
