Chlorine Conversion & Hydrant Flushing

Fall chlorine conversion and flushing program

                         The Department of Natural Resources requires every city that treats their drinking water with chloramine disinfection to convert once a year to a free chlorine residual disinfection for at least 30 days. The City of Vandalia will be making that conversion during the months of October and November. It will start on October 16th and finish on November 16th. This annual switch to free chlorine is a key component in our quality assurance program.

 During the conversion from chloramine residual to free chlorine, customers may notice increased chlorine tastes or odors in their water. These are normal reactions and do not affect the safety of your drinking water.

Also during this change, the City will be conducting their fall flushing program.  The City will begin flushing on November 16th and will complete on November 30th.   Consumers may notice changes including fluctuating pressure and occasional cloudy water or aerated water that appears milky when first drawn from the tap.

 As always, if you have any questions or concerns about your water supply, feel free to call City Hall at 573/594-6186 or the water plant at 573/594-3014.
