How would the additional pumper supply water to the pumper on the highway?

• A. The pumper off highway would establish water supply and pumps via a dry standpipe rise, then the pumper on the highway can use the standpipe discharge to receive steady water flow.
• B. The off-highway pumper would tow the other pumper.
• C. The on-highway pumper must improvise with air pressure only.
• D. The water supply is not shared.

Answer: (A)

The idea is to create a shared, steady water supply between pumpers by using a dry standpipe rise. The pumper off the highway sets up a water source and pumps water into a dry standpipe that rises to where the on-highway pumper can access it. The standpipe discharge at the top connects to the on-highway pumper, which then draws water from the standpipe and continues to supply attack lines. This setup keeps a continuous flow available to the highway pumper even when hydrants aren’t nearby, or when multiple lines need to be fed. Towing the pumpers would not establish a water supply. Relying on air pressure only would not provide the required sustained flow. And saying the water supply isn’t shared ignores how the standpipe transfer is specifically designed to deliver water to the on-scene unit.
