What color is used for sewage system hand wheels?

The color commonly associated with sewage system hand wheels is dark green. This color coding is part of the standardized system used in various industries to ensure safety and easy identification of different utilities and systems. Dark green specifically indicates that the valves or hand wheels control sewage systems, which helps maintenance personnel quickly recognize and operate the equipment necessary for sewage management.

Gold does not correspond with any standardized color code for sewage systems, and so it would not be the correct choice in this context. Understanding this color-coding practice is crucial for ensuring safety and efficiency in managing water and sewage systems, reducing the risk of confusion or accidents in facility operations.
