Free Chlorine Burnout, July 7 - August 4
● Why are we temporarily switching from chloramines to free chlorine?
Chloramine is a very stable and long-lasting disinfectant in water systems. As a maintenance activity to
optimize the water quality of the distribution system, the water plant will switch to free chlorine for
disinfection for a period of about one month, or until the distribution system has been completely flushed for
the following reasons: Remove any biofilm and bacteria from the water distribution system pipes; Reduce
the formation of nitrates and nitrites (nitrification); Reduce any taste and odor complaints; This maintenance
process is recommended by the US Environmental Protection Agency (EPA) and Kansas Department of
Health and Environment (KDHE). After distribution system flushing is completed, the water plant will
resume disinfection utilizing chloramines.
● During this maintenance process, is the water safe to drink and use?
Yes. The water is safe to drink and use as normal. Customers may notice slight discoloration/cloudiness or
chlorine odor, but it is safe to use. Water users sensitive to chlorine or chloramine should take normal
● What effects may customer observe during this maintenance/flushing process? Customer may see some
of the following during this maintenance process:
○ A slight discoloration or cloudiness in the water;
○ A slight chlorine odor or taste;
○ Minor fluctuations in water pressures while flushing is occurring;
○ Minor discoloration in the water due to flushing the system;
○ Utility crews operating fire hydrants to flush the system.
Many customers may not notice any change in the water.
Critical users such as hospitals, dialysis groups, pet/aquatic/pond companies, companies that use water for
processing, and other water users sensitive to chloramines or free chlorine should consult with their
professionals about their internal treatment procedures.
● What should customers do if they experience any discoloration or odor?
If the water is discolored or cloudy, flush the water through an outside spigot or tub faucet for a few minutes
to clear. By running the water through a spigot or tub faucet, the problem clears faster and if any debris
particles have been stirred by flushing, it will not clog faucet strainers.
