The dumpsite pumper in an MWS setup draws water from which source?

• A. Portable water tank
• B. Hydrant
• C. Internal tank of attack apparatus
• D. Ground water from pond

Answer: (A)

In a Mobile Water Supply setup, water is staged in portable tanks at the dumpsite and becomes the primary reservoir for the system. The dumpsite pumper is positioned to draft directly from that portable water tank so it can feed water onward to the attack pumper or to the fire lines. This arrangement allows the system to operate where hydrants aren’t available and keeps the water flow independent of the attack apparatus’s own tank.

Hydrants aren’t the direct source for this component because the dumpsite’s role is to move water from the portable tank, which is filled from a supply unit elsewhere. Drawing groundwater from a pond would require a separate intake and setup beyond the dumpsite pumper’s standard role. The attack apparatus’ internal tank isn’t the dumpsite’s source either; it’s the receiving/using tank for the attack pumper, not the origin for the dumpsite transfer.

So, the dumpsite pumper draws water from the portable water tank.
