Do You Know What Each Flag Color Means?

July 9, 2018

Before we install fiber-optic internet in your yard, we have to “Call 811” or 1-800-344-7233 to make sure we don’t dig into your gas, electric, or water lines. There’s a very careful and thoughtful system put into place when we are installing Fiber To The Home, and step one is calling 811!

You’ve probably noticed small flags of various colors placed in the grass around town or in your neighborhood, and most of you know about these flags, but it’s always good to have a refresher on what each color means. This may be a good memory game to play with your children so they know what these flags are and how to associated them with a specific utility.

The American Public Works Association has color-coded all utilities so it’s easy to locate and makes it easy to immediately identify which utility is running where.

 

The following is a key to the flags’ colors

Red: Electric power lines, cables, conduit and lighting cables

Orange: Telecommunication, alarm or signal lines, cables or conduit

Yellow: Natural gas, oil, steam, petroleum or other gaseous or flammable material

Green: Sewers and drain lines

Blue: Drinking water

Violet: Reclaimed water, irrigation and slurry lines

Pink: Temporary survey markings, unknown/unidentified facilities

White: Proposed excavation limits or route


If flags are in your yard, please do not remove them. If they’re marked with a logo and the name of the utility, feel free to give them a call to inquire about their placement, but for safety purposes, remember to leave them where they are. With Craw-Kan, these flags keep our contractors safe, as well as you and your neighborhood. Remember, Don’t Get Bit, Get GIGABIT!
