Marking Flags

Before you dig, it's critical to know where the utility lines are located throughout your property. Clearly identify boundaries and potentially hazardous pipes that lie underground with Marking Flags. Marking Flags are available in two different sizes and in standard and fluorescent color options. Standard colors are in accordance with the American Public Works Association (APWA) Uniform Colors Code.

Place Red Marking Flags to indicate buried electric power lines, cables, conduit, or lighting cables below. Blue Marking Flags are used to mark water line below. Purple Marking Flags communicate reclaimed water, irrigation and slurry lines. Before you place Marking Flags, learn more about the APWA Uniformed Color Codes.
