When does the need for pumped water typically arise?

The need for pumped water typically arises during the late second alarm assignment because, by this stage of an incident, the fire has often escalated in severity, requiring more substantial water supply to combat the flames effectively. At this point, resources may be stretched, and additional pumpers may be called to provide the necessary water flow. A late second alarm assignment indicates that the situation has progressed to a level where more firefighting capabilities are essential, and the need for a reliable water source becomes critical as the fire demands more extensive operations.

In contrast, the first alarm assignment is usually sufficient for handling initial incidents, and immediate water needs upon arriving on scene are often addressed with existing resources. While it is true that water could be needed at any time during an incident, particularly if the situation changes, the ordering and strategic resource allocation typically emphasize the need for additional water during escalated phases, such as the late second alarm.
