Civil and earthworksDust control and soil compaction can burn through thousands of gallons a day. Water trucks fill at the hydrant over and over, so the meter and its RPZ are the first thing set on the job and the last thing to leave.
Roadwork and pavingMilling machines spray water on the cutting drum to cool the teeth and hold down dust, and crews mix and cure concrete on site. Road jobs move every day, so the meter moves too, and every move means the RPZ gets retested.
Utility and undergroundDirectional boring mixes its drilling mud from hydrant water. New water and gas lines get filled and pressure-tested, and new mains get flushed before tie-in. All of that water runs through a hydrant meter.
Commercial and maintenanceHydro-demolition, industrial pressure washing and sewer jetting trucks use a lot of water on sites with no tap to hook to, so they pull it from a hydrant.
