About water main breaks

Three photos of different flushing techniques. First is water flowing out of an orange hydrant and gently splashing on the curb and street with a blue sign behind saying "flushing our system to maintain water quality". The middle photo has a woman opening a valve on a hydrant that has a hose connected to it and water is spraying out the end of the hose. The last photo is of a orange hydrant that has a red box - the autoflusher - attached to the side and water is splashing out the bottom of the box.
