Special notice for customers who use water for kidney dialysis machines, fish aquariums or other chlorine-sensitive uses: Please be aware water may contain chlorine, chloramines or a mixture of the two during the month of March.
Beginning March 1 through March 31, 2020, the Town will use only chlorine for disinfection of the water. Each year, the Town of Cary implements a temporary change in the drinking water treatment process. The Cary/Apex Water Treatment Facility, which provides drinking water to Cary, Apex, Morrisville, Raleigh-Durham International Airport and the Wake County portion of Research Triangle Park, normally uses chloramines, a combination of chlorine and ammonia, for the disinfection process. The State of North Carolina encourages all water systems that add ammonia to cleanse their system annually by switching to chlorine only and flush the system by opening fire hydrants.
Some may notice a more distinct chlorine odor during this time. However, the water remains safe throughout this process. If you would like to reduce the amount of chlorine in the drinking water to improve its taste and odor, you may do so through several methods, including filtering the water using an activated carbon filter, letting the water sit out for a day or so, boiling the water for one minute, or adding a few lemon slices to a pitcher of water. The lemon has ascorbic acid which will naturally dechlorinate the drinking water.
Some may notice a temporary discoloration of water that may occur due to nearby hydrant flushing. Citizens are encouraged to check their water before washing white clothes. If the water appears discolored, run all household faucets for a few minutes.
Citizens who have questions or who have water that fails to clear should contact the Town of Cary. Call 311 within Cary or (919) 469-4000 outside town limits.
