The Michigan City Department of Water Works will begin the semi-annual fire hydrant flushing on Monday April 10.
This is done to ensure the hydrants are in proper working order for the spring and summer months, and also to find any hydrants that may have been damaged over the winter.
The department says the program should take around eight weeks to complete.
If anyone should experience any discoloration in their water, they should let the water run for a short time and the water will clear.
