The River Forest Fire Department flush and test every fire hydrant in the Village annually. This is an important process to remove any sediment that may be in the line and to ensure all hydrants are in working order in case of a fire. Water discoloration may occur during hydrant flushing, however, the discoloration is harmless. Running water from a fixture in the lowest section of your home until clear will correct this problem. Please avoid doing laundry or using a dishwasher until water runs clear.
