The City of Bismarck will begin converting the water distribution system disinfectant to chloramine on Tuesday, April 9. City crews will be flushing hydrants throughout the city for a week to 10 days to provide a uniform chloramine residual throughout the system.

Customers should not expect to notice much change in their water. In some cases customers may notice a stronger than normal chlorine odor as the water containing chloramines mixes with the water containing free chlorine. This should be for a very short time period and can be eliminated by running your water to flush the lines.

This change will affect all customers in the Bismarck area, including those served by the City of Lincoln and South Central Regional Water District.

Customers with aquariums or fish ponds should be aware that they must use chemical methods to remove the chloramine residual from the water before exposing their fish to it. Chloramines cannot be removed by boiling the water, letting it stand for several days, or adding salt. Local pet shops are aware of the proper methods to neutralize chloramines and have the necessary products available.
