Annual Change in Chlorine Disinfection

The Miami-Dade Water and Sewer Department (WASD) will temporarily change its method of chlorination at each of its regional water treatment facilities. Specifically, free chlorine treatment will be used to provide a somewhat stronger disinfection and bleaching process than the combined chlorine treatment which is normally used at our regional water plants. This annual process has been ongoing since 1983. This water is chlorinated, disinfected, and may be safely consumed.

This is to be scheduled for September 9 – 22.

What to Expect

  • Slight chlorine taste and/or odor in the water
  • Consumers may notice WASD vehicles flushing fire hydrants during this two-week period to ensure that water with a “Free-Chlorine” residual reaches the system’s extremities.
  • Slight decrease in pressure when hydrants are being flushed in your area.
  • No adverse effects to pets (except for tropical fish)
  • Temporary discoloration of the water, as water rushing out of the hydrant removes rust and sediment particles from pipes.
