Coral Gables has begun testing all 1,400 of its fire hydrants, a program that will run seven days a week through February 2027.

Crews are checking water flow, clearing lines and verifying that valves function properly for emergency use, the city announced Friday, Sept. 25. The annual testing runs daily from 7:30 a.m. to 5:30 p.m. Residents with questions can call 305-460-5581.

The hydrant program is separate from a countywide water project that will overlap with it. Miami-Dade Water and Sewer plans to temporarily switch from chloramine to free chlorine disinfection from Monday, Sept. 28 through Sunday, Oct. 11, according to a notice posted by the Village of Pinecrest, which shares the county water system with Coral Gables.

During the two-week chlorine conversion, residents may notice a slight chlorine taste or smell, brief dips in water pressure and occasional water discoloration. Miami-Dade Water and Sewer says the water remains safe to drink.

The city's hydrant testing announcement did not mention water discoloration as an expected effect of that program.

Dialysis patients, tropical fish owners and businesses with fish tanks should seek professional advice on removing chlorine from their water during the conversion period, the county advises. More information on the chlorine switch is available at miamidade.gov/water.
