Each year during the month of March, the Cary/Apex Water Treatment Plant implements the annual switch from chloramine disinfection to free chlorine disinfection.
During the disinfection switch in the month of March, the water will continue to be completely safe to drink but some consumers may notice a stronger chlorine taste and odor.
Kidney dialysis users should be aware that your water may contain chloramine, chlorine, or a mixture during the month of March. During the month of April, the water plant will return to the use of chloramine disinfection. Mixtures of chlorine and chloramine may still be present in the early days of April.
Aquarium owners should use neutralizers that work on chlorine as well as chloramine during this time period. Please contact your local aquarium supply dealer for more information.
This change is being coordinated with an identical switch by other local municipalities. Periodic alternate disinfection is mandated by State and Federal regulatory agencies.
Annual Water System Flushing—Clearing the Lines
Annual water distribution system flushing will be coordinated with the March disinfection switch. Public Works employees will be in Apex neighborhoods from March 1 ‐ April 1 opening fire hydrants in a planned sequential order to flush the entire water distribution system. Crews will make every effort to avoid disturbances to yard waste and trash carts in the curb. Some work may be performed at night to avoid inconvenience to residents.
During or just after the time of this flushing operation, residents are urged to check their water before washing white clothing. If the water appears discolored, try running household faucets for a few minutes to flush household lines. If the water fails to clear, call Public Works at (919) 249‐3427 for further assistance.
