The City of Carroll, Iowa has begun its annual spring hydrant flushing program, which involves opening each of the city's 500 fire hydrants over the next month to clear rust and other debris from the water mains. Crews will work weekdays from 8am to 3pm, flushing around 25 hydrants per day, in an effort to remove any buildup before it reaches residents' taps.
