Vero Beach Switches to Chlorine Water Disinfectant April 17, Urging Dialysis Patients to Prepare

Vero Beach residents on kidney dialysis — and the clinics that treat them — need to take action before April 17, when the city's Water and Sewer Department switches its drinking water disinfection method for nearly three weeks of annual maintenance.

From April 17 through May 6, 2026, the city will use free chlorine rather than its standard disinfectant, chloramines — a compound formed by combining chlorine and ammonia. Free chlorine levels may reach 3.5 parts per million, or milligrams per liter, at times during the period, according to a public notice issued by Jeffrey W. Howard, chief operator of the Vero Beach Water and Sewer Department. For most residents, the change poses no health risk. For dialysis patients, it is a medical concern that requires immediate coordination with their care team.

Dialysis machines filter a patient's blood directly through water-based solutions. Unlike the human digestive system, the dialysis process cannot neutralize disinfectants before they enter the bloodstream. Both free chlorine and chloramines must be removed from water used in dialysis treatment — but the two chemicals require different removal protocols. A sudden or mixed disinfectant signal can catch unprepared clinics off guard.

Howard's notice warned that during the transition, water in Indian River County homes and facilities within Vero Beach's service territory may contain free chlorine, ammonia, chloramines, or a combination of all three — an especially complex mix that dialysis providers must account for in their pre-treatment systems.

The city plans to resume adding ammonia to re-form chloramines on May 7. Even then, Howard cautioned, residual free chlorine will persist in various parts of the distribution network for roughly one additional week as it is gradually displaced by the returning chloramine-treated supply — meaning the full transition period effectively extends to around May 14.

Dialysis patients and home dialysis users in the Vero Beach service area should contact their nephrologist or dialysis center immediately to confirm that treatment protocols have been updated for the changeover.
