Which hydrant color and flow combination indicates the highest capacity?

• A. Green 1000-1499 gpm
• B. Red less than 500 gpm
• C. Orange 500-999 gpm
• D. Light blue 1500 gpm

Answer: (D)

Hydrant color coding communicates potential flow capacity. In this system, red means under 500 gpm, orange 500–999 gpm, green 1000–1499 gpm, and light blue 1500 gpm or more. The light blue hydrant with 1500 gpm represents the highest capacity among the options, since 1500 gpm is greater than the other ranges listed.
