IFSTA recommends water shuttle operations use at least ______ pumpers.

• A. 1 Pumper
• B. 3 Pumpers
• C. 2 Pumpers
• D. 4 Pumpers

Answer: (C)

Water shuttle operations rely on keeping water moving from the source to the scene without interruptions. The minimum setup uses a pair of pumpers because it creates a simple relay: one pumper fills and primes the shuttle and begins pushing water into the shuttle system, while the other pumper draws water from the shuttle and delivers it to the attack engine or fire line. With this arrangement, if one unit needs to reposition, refill, or relieve a duty, the other can continue providing water, preserving flow to the nozzle. Having only a single pumper would lack this backup, risking a stop in water supply during refilling or movement. Adding more pumpers than the minimum can improve capacity for longer shuttle operations or larger flows, but the essential requirement is two pumpers to ensure continuous water delivery.
