APWA Utility Color Code

To avoid confusion, the American Public Works Association (APWA) developed a Uniform Color Code used nationwide for utility markings. This standardized color system means that each color corresponds to a specific type of utility. Whether markings are paint, flags, or permanent posts, the colors stay consistent so everyone knows what buried lines are present.
