This allows the chlorine to dissipate, thus reducing the chlorine taste. If you are especially sensitive to the taste and odor of chlorine, try keeping an open container of drinking water in your refrigerator.

What customers can expectĭepending on your usage patterns and location within the distribution system, it may take up to a week for your drinking water to transition from combined to free chlorine or from free chlorine back to combined chlorine at the conclusion of the disinfection chemistry change period.ĭuring the time that free chlorine is used, you may notice a chlorine taste and odor in your drinking water. By switching to free chlorine, the biofilm is “shocked” and weakened. The use of free chlorine for this short period of time also helps control biological film, known as biofilm, which is found in all water pipes and can lead to water quality problems if not controlled. This also enables the Town to test and perform routine maintenance on the more than 800 fire hydrants within its service area. Water mains are flushed by opening fire hydrants and allowing the water to flow freely for a short period of time. Free chlorine is somewhat more volatile than combined chlorine, which allows it to react with sediments suspended during flushing. During the flushing program period, chlorine is added in an uncombined state, commonly referred to as free chlorine. This allows Vienna and others in the Fairfax Water service area to perform annual fire hydrant flushing.ĭuring most of the year, chloramine, also known as combined chlorine, is added to the water as the primary disinfectant. The Town's flushing program happens at the same time that Fairfax Water Authority switches from chloramines to free chlorine for water treatment during a brief period each year. Temporary change to treatment with free chlorine In 2021, flushing will take place from 10 pm-7 am March 26-May 21. Multiple factors contribute to prioritization of pipes for rehabilitation or replacement.To help maintain a high standard of water quality and ensure proper and efficient operation of fire hydrants, the Town of Vienna flushes water mains in its distribution system each spring.
