It is so important to avoid dangerous situations and expensive fixes by calling Texas811 before you dig. As an excavator, it’s a good idea to be familiar with the utility flagging color code and what each color stands for.
White: The white flag marks the proposed excavation site and indicates where exactly the digging will occur during the job. It’s good to look out for these and get a sense of how big or small the project will be so that you can scale accordingly.
Pink: The pink flag signifies temporary survey markings. If there is some utility that cannot be identified, then it will be marked with a pink flag.
Red: The red flag marks where the electric power lines, cables, conduit and lighting cables are. These are especially important to watch out for, because digging around these areas could cause serious damage.
Yellow: The yellow flag marks where the gas, oil, steam, petroleum or gaseous materials lie.
Orange: The orange flag marks the communication, alarm or signal lines, cables or conduit.
Blue: The blue flag marks where the potable water lines are. Marking these helps excavators use the safest measures possible when digging on a job.
Purple: The purple flag marks all the reclaimed water, irrigation and slurry lines. These will ensure that the reclaimed water stays intact during the excavation process.
Green: The green flag marks where the sewer and drain lines are.
Remember, call Texas811 before digging to avoid hitting any of these underground utility lines, no matter what the job is.
