— BOCA RATON ACTIVE TREATMENT UPDATE
Why Boca Raton tap water may smell more like chlorine through October 11
City of Boca Raton Utility Services is temporarily using free chlorine instead of chloramine and flushing hydrants from September 27 through October 11, 2026.
- The change applies to customers served by City of Boca Raton Utility Services—not every address with a Boca Raton mailing address.
- The City describes it as planned distribution-system maintenance, not a boil-water notice or contamination finding.
- Customers may notice a slight chlorine taste or odor, brief discoloration, flowing hydrants or localized lower pressure.
- Home dialysis users and people caring for fish or aquatic animals should follow the City's special-use advice.
What is Boca Raton changing?
The City says its water-treatment facility will produce a free-chlorine residual instead of its usual chloramine residual for two weeks. The announced period began Sunday, September 27 and ends Sunday, October 11.
Hydrant flushing will continue during the same period as part of the City's distribution-system maintenance program.
The City says the temporary taste, odor, discoloration and pressure conditions expected during the program do not cause adverse health effects. A separate notice would require its own address-specific instructions.
Who is affected?
The announcement is for customers served by City of Boca Raton Utility Services. Boca Raton-area homes can be served by different utilities, so residents should confirm the provider printed on the water bill before relying on this schedule.
What might customers notice?
The City says customers may notice a slight chlorine taste or odor. Hydrant flushing can also cause flowing water in streets or swales, localized lower pressure and slight tap-water discoloration.
Persistent discoloration, particles, unusually strong odor or a pressure loss should be reported to the utility rather than automatically attributed to routine maintenance.
Who should take special precautions?
The City advises home kidney-dialysis users, aquarium owners and businesses with fish or shellfish holding tanks that methods for testing and removing free chlorine differ from those used for chloramine. People affected by that distinction should seek advice from the appropriate medical or aquatic-care professional.
What should residents do?
- Confirm the provider. Check that the bill names City of Boca Raton Utility Services.
- Expect a possible temporary taste or odor change. The announced period runs through October 11.
- Check for a separate notice. A main break, pressure event or boil-water notice would have different instructions.
- Call the utility about system-wide conditions. Boca Raton Utility Services lists 561-338-7300 for customer questions.
