In the hydrant color/flow coding scheme, which option represents a hydrant with less than 500 gpm?

In the hydrant color/flow coding scheme, which option represents a hydrant with less than 500 gpm?

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

Answer: (D)

Hydrant color/flow coding uses color to convey the approximate available flow in gallons per minute. In this scheme, red means under 500 gpm, orange indicates 500–999 gpm, green corresponds to 1000–1499 gpm, and light blue represents 1500 gpm or more. Therefore, the hydrant described as red with less than 500 gpm is the one that matches the category of under 500 gpm. The other colors correspond to higher flow ranges, so they do not fit the “less than 500 gpm” category.
