The city of Bismarck is changing its water system.Chloramine is being added to the water disinfectant, so city crews will be flushing the hydrant system for approximately the next 10 days. As a customer you may notice a stronger than usual chlorine odor, this can be eliminated by running your water to flush the line. This change effects Bismarck,Lincoln and south central regional residents. If you have fish or an aquarium please contact local pet shops to best dissolve the chloramine in your water before exposing your fish to the chemical.
