Boca Water Customers May Notice Chlorine Taste During Temporary Treatment Change

Some Boca Raton water customers may notice a temporary chlorine taste or odor in their tap water starting late September. City of Boca Raton Utility Services is temporarily switching from chloramine to free chlorine from September 27 through October 11, 2026, as part of routine maintenance.

The city says the water remains safe to drink throughout the change. The temporary switch is a standard water-distribution maintenance practice, not a response to any contamination issue.

What customers may notice

During the switch, customers may notice a temporary chlorine taste or odor in the water. The city also advises that hydrant flushing during this period may temporarily cause localized lower water pressure, water discoloration, and water flowing in streets or swales.

Who is affected

This notice applies to customers served by City of Boca Raton Utility Services. It does not automatically apply to every West Boca household or every Boca Raton mailing address, because parts of unincorporated West Boca are served by other utility providers. Residents who are unsure should check their water bill to confirm their provider.

Guidance for dialysis users and aquarium owners

The city advises that home-dialysis users and aquarium or fish and shellfish tank operators seek professional guidance during the temporary change, because the methods for removing free chlorine differ from those used for chloramine. MyWestBoca.com is not providing medical or chemical-treatment instructions; affected customers should consult their equipment provider, physician or aquatic specialist.

This is a separate drinking-water maintenance story. It is not connected to the earlier wastewater spill and no-swim advisory that affected Camino Real, Lake Boca and the Intracoastal Waterway.
