A water shuttle is a tactical operation employed to transport water from a designated source, such as a hydrant or water tank, to a fire scene when direct supply is impractical. This operation typically involves multiple fire apparatus making continuous trips to ensure a sustained water supply for firefighting activities. Not to be confused with a hydrant relay, which relies on stationary apparatus connected directly to a hydrant, a water shuttle is essential in scenarios where water sources are distant or limited, often coordinated under the Incident Command System (ICS).
