What describes a direct pumping operation in a water shuttle?

A direct pumping operation in a water shuttle specifically involves mobile water supply (MWS) apparatuses that are designed to pump water directly into the fire pump of the attack apparatus. This method is efficient and allows for continuous water flow to the fire scene without the need for intermediate steps, such as transferring water to portable tanks. The direct connection minimizes time lost in transferring water, ensuring that the fire attack is supported as quickly as possible.

The focus on direct pumping distinguishes this operation from other practices that might involve different equipment or procedures, such as solely using a nurse tanker or relying on hydrants for refilling. By directly connecting the mobile water supply to the attack fire pump, it streamlines the water supply process, making it an effective strategy during firefighting operations.
