"Water Shuttling Operations" are fairly common. Way back when, when I was a volunteer firefighter, we trained and drilled on that frequently. Even in areas with hydrants close by, that many pieces of equipment over-burden the water supply. Therefore a "Draft Tank" is set up to siphon water from. Tanker trucks will go to another water source (I have even been part of this operation that drafted water from swimming pools) is located and the water is brought in a circuit to the tank.
