In the context of static water sources, which statement is true?

• A. The distance to the incident is a factor to consider.
• B. The static water source closest to the incident should always be used first.
• C. Static water sources vary in supply and distance.
• D. Hydrant availability does not affect static water source choice.

Answer: (A)

In static water operations, how far the water source is from the fire scene drives the entire water supply plan. Water has to be moved from the source to the incident by pump and hose, and every extra distance adds friction losses, requires more suction head, and costs time. The pump must generate enough pressure to overcome suction lift from the source and the friction losses along the hose as it reaches the nozzle. The farther the source, the greater the potential drop in available discharge pressure and the more likely you’ll need additional equipment or multiple pumps to keep a steady flow. So, distance to the incident is a factor you actively consider when selecting a static source and designing the water supply strategy. If a nearer source can deliver adequate water with acceptable pressure, it’s preferred; if not, you may have to relay water from a distant source or use additional sources to maintain the needed flow. Hydrant availability and how much water a source can provide are real considerations as well, but the fundamental point tied to static sources is that distance directly impacts pressure, flow, and the logistics of delivering water to the scene.
