The Importance of Colors of Underground Utility Lines

If you find underground utilities, you can easily determine what type of utility it is for. Before, it was difficult to do so and people were at risk if they try to make a dig without being able to identify all the lines underneath the land. Today, the risks have been lessened although not completely eliminated. If there is a need to dig the ground, it is very important that the utility lines first be identified. If you need to dig through a piece of land today, you are required by the OSHA to first identify or locate underground utilities. It is to prevent disaster. The worst thing that can happen if lines are not identified is that fatal injuries can happen. It can also interrupt services in your area where the line is located. Before digging their property, people should call 811 to call the utility companies so that these incidents are prevented. Utility companies can then mark out their respective lines when you call them out.

Sometimes, even if the lines are marked accidents still happen. The reality is that there is an incident almost every 6 minutes where utility line are struck. When this happens, it affects traffic lights, wastewater pipes, telecommunication lines and more. These incidents affect public health and safety.

GPR or Ground Penetrating Radar is used by companies to locate their utility lines. When locating utility lines underground, this machine makes it easy to do so. Calling 811 is enough for the property owner to let companies located their lines.

There are certain colors that mark different utility lines for easy identification. Here are the colors used for different utilities.

Proposed excavation sites use white lines. You can mark areas with white lines that will soon be excavated.

Pink lines are temporary survey markings. Legal property boundaries are marked off by these pink lines.

Electric power lines, cable, conduit, and lighting cable use red lines. This color is appropriate for electrical works since it is associated with fire and danger.

Lines for gas, oil, steam, petroleum, and gaseous materials use the color yellow. The bright color yellow is used to be a warning sign since a natural gas leak can create a potentially disastrous situation.

Communication, alarm, signal lines, cable, or conduit use orange lines. Blue lines are used for potable water. If you see purple lines, that this is for reclaimed water, irrigation and slurry lines. If you see the color green, then it indicates sewer and drain lines. You can derail any project for a long time if you hit these lines.
