1. As a reservoir or "nurse tanker/tender" for some fires
2. In a water shuttle operation — Some apparatus use a built-in vacuum pump that expels the air from inside the water tank so that water from a static supply can be drawn into the tank, reducing the amount of time needed to refill the water tank, and increasing the efficiency of water shuttle operations
What factors play into choosing the size of a water tank?
1. Terrain — The mobile water supply apparatus may be required to climb steep hills or to operate on winding roads
2. Bridge weight limits — Bridges in the fire department's normal response district may be too old or may not be designed to bear the weight of heavy mobile water supply apparatus. This presents a danger to firefighters as they drive over these bridges if alternate routes are not available.

What does "pump and roll" mean?
A separate motor or a power take-off powers the fire pump, enabling the apparatus to be driven and discharge water at the same time
What are two different "pump and roll" methods?
