Harmony area temporary water treatment change

Beginning September 18, 2025, Toho Water Authority (Toho) will temporarily switch the disinfectant in the public water system that serves the Harmony area from chloramines to free chlorine for maintenance of water quality in the distribution system.

While this process is routine in function, and we most recently conducted this in June/July 2025 for our system, we are accelerating the next scheduled maintenance event as a continuation of our flushing response to the recently resolved precautionary boil water advisory for our Harmony area customers.

The Florida Department of Environmental Protection (FDEP) requires water utilities to notify customers whenever changes are made in disinfection processes. The area water treatment facility has used free chlorine to treat your water in the past. This periodic maintenance procedure is a standard practice used nationwide. Customers will receive a letter by mail which is also found in the documents section of this page.

This system maintenance is expected to be completed by October 17, 2025. Customers will be notified when the disinfection treatment process is returned to chloramines.

Please see more details below.

Taste and smell

You may notice a stronger chlorine taste and smell in your drinking water. The taste and odor are not a health risk. Chlorine levels are monitored to meet safety standards. By its nature, free chlorine presents a stronger taste and odor than chloramines. To reduce the chlorine taste and smell, run the faucet with cold water for two minutes. Run it for five to ten minutes when water has not been used for several hours. You can also refrigerate cold tap water in an open pitcher. Within a few hours, the chlorine taste and odor will disappear.

Do I need to take any precautions during the temporary switch?

Any disinfectant used by water treatment facilities needs to be removed or neutralized from the water for use in dialysis machines or aquariums.

Care must be taken to remove all traces of free chlorine from water used in dialysis machines. Contact your physician or kidney dialysis center for information and proper procedures.
To condition tap water for use in aquariums, fish owners should use products recommended for neutralizing free chlorine. Contact your pet store for the appropriate water treatment.
Customers with water softening systems should consult the manufacturer for measures to take, if any.
