Annually, the City of Naples Water Department temporarily changes the disinfection process for the City’s potable (drinking water) water supply as part of water quality maintenance. Beginning Thursday, June 1, 2023, through Friday, June 30, 2023, the Water Department will disinfect the water with free chlorine rather than combined chlorine/ammonia (chloramines).

This annual conversion to free chlorine (a stronger disinfectant) from chloramines (a longer-lasting disinfectant) allows a water distribution system purge as recommended by the Department of Environmental Protection for water utilities using chloramines as their primary disinfectant. This temporary change in disinfectant does not cause adverse health effects. However, during the period customers may experience a slight increase in the taste, odor, and color of the water due to the change in treatment.

Customers on kidney dialysis who use a proportioning machine to prepare dialysate at home are advised to contact their equipment supplier or physician to take any appropriate steps to accommodate the change in water disinfection and to install the proper filtering devices if needed. Customers who have fish tanks or other aquatic species are advised to contact the local pet store to ensure proper pretreatment of the water before adding or changing the water in the tank to avoid any problems associated with chlorine.

Customers are asked to call the Water Plant at 213-3004 with any questions concerning this temporary change in disinfection. Thank you for your understanding during this short period.
