Notice from NMB Water

NMB Water Annual Chlorine Disinfection

In conjunction with the Miami-Dade Water and Sewer Department, NMB Water will be performing system maintenance involving chlorine disinfection of the water distribution system from November 7 – 19, 2023. During this time, the Norwood Water Treatment Plant will switch from chloramine to free chlorine disinfection and then flush the system fire hydrants. System disinfection and flushing will maintain water clarity and quality for customers.

This system maintenance will apply to all NMB Water customers in North Miami Beach, Miami Gardens, Aventura, Sunny Isles Beach, Golden Beach, and portions of unincorporated Miami-Dade County.

As part of this routine maintenance chlorine disinfection, customers may notice:

  • Temporary discoloration of the water
  • Some sediment particles from the flushing
  • Slight chlorine taste and/or odor in the water

This water is chlorinated, disinfected, and may be safely consumed; however, if you are especially sensitive to the taste or odor of chlorine, keep an open container of drinking water in your refrigerator for a few hours to allow the chlorine to dissipate. Users of home dialysis machines, owners of tropical fish and managers of stores and restaurants with fish and shellfish holding tanks are advised to seek professional advice as to the method for removing chlorine residuals in tap water during this time.

NMB Water staff working in the community will always wear a reflective safety vest, carry identification, and place signs that work is in progress. If you have any questions about this upcoming maintenance, contact Customer Service at 305.NMB.WATER (305.662.9283) or email
