Which hydrant color corresponds to 1500 GPM plus?

• A. Red
• B. Orange
• C. Green
• D. Light Blue

Answer: (D)

Hydrant color coding communicates the approximate water flow available at a hydrant, so crews can quickly gauge the water supply for firefighting operations. In this scheme, light blue indicates 1500 GPM or more, which is why it’s the best choice for 1500 GPM plus. This helps determine whether a single hydrant can meet high-flow needs or if additional sources are required. Other colors map to lower flow ranges (red for the lowest, orange for moderate, green for around 1000–1499), but they don’t signify the 1500 GPM+ level.
