SIOUX CITY -- Sioux City's utilities department will begin flushing fire hydrants beginning Monday.
According to a press release from the city, hydrant flushing is a necessary maintenance function in which sediment is expelled from the distribution system. The hydrants are opened and allowed to flow until the water runs clear.
The flushing will start at the water plants and work outward. The flushing will start on Gordon Drive and go north, working between Lewis Boulevard and Highway 75.
City tap water will remain safe to drink, though there may be a temporary drop in water pressure during testing. Water may become discolored after flushing, but city workers will try and keep discoloration to a minimum.
If you notice discolored water, run your cold water tap for a few minutes until the water clears. If it does not clear the first time, wait a few minutes and run the water again. If the water has not cleared after several hours, call the utilities division at 279-6164. Avoid washing clothes until the water clears.
