If you live in Moline your tap water might be a little discolored and you might have low water pressure.
But the Public Works Department says it's nothing to worry about.
Starting Monday, crews are flushing Moline fire hydrants to clean them out.
It'll take about three weeks for workers to open all the city's hydrants.
Officials say they need to be flushed to check the water quality and to make sure the water is flowing properly.
