APWA Uniform Color Code

The APWA, American Public Works Association, developed a color code for temporarily marking underground facilities prior to excavation. The color code encourages all excavators, surveyors and engineers to use these colors to promote and eliminate damages to workers, general public and prevent service interruptions to vital underground utilities.

Marking underground utilities with paint, flags, surface markers and underground marking tapes allows all excavators to understand the types of facilities and the approximate locations and routes of buried lines.
