In Edmonton, which hydrant color corresponds to the highest discharge rate?

• A. Green
• B. Orange/Yellow
• C. Red
• D. Blue/Black

Answer: (C)

Understanding hydrant color coding is about quickly knowing how much water a hydrant can deliver. In Edmonton, the color assigned to a hydrant reflects its discharge rate, with red indicating the highest capacity. This lets crews decide early whether a single hydrant will meet water needs or if additional sources are required, and it guides pump settings and hose-line choices during a fire attack. Other colors point to progressively lower discharge rates, helping the same planning when the red hydrant isn’t available nearby. Hydrant color information is typically visible on the hydrant itself or on nearby markings and is used by Edmonton Fire Rescue Services to plan efficient and safe water supply during operations.
