Undergoung Utilities and their Standard Colors

It is now easier to know what an underground utility line is for. The risk was high before when people could not easily identify the type of utility lines underneath whenever they dig. Although not completely eliminated, risks today have been reduced. In order to prevent harm, it is important to know or identify these utility lines if your need to dig the ground. The OSHA requires that utilities underground first be located before digging through a piece of land. It is to prevent disaster. If you hit any of the underground utility lines while digging then you can be fatally injured. 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. When the number is called, you can let the utility companies come out and mark their respective lines.

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

With the use of GPR or Ground Penetrating Radar, companies can locate utility lines. When locating utility lines underground, this machine makes it easy to do so. Companies can locate their utility lines if any property owner calls 811.

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. Area that will be excavated in the future are marked.

If you see pink lines, they are temporary survey markings. Surveyors use pink lines to mark off legal property boundaries.

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. Bright yellow is an appropriate warning color since it is very disastrous to have a natural gas leak.

Orange lines are used for communication, alarm, signal lines, cable or conduit. If you see blue lines then these are lines for potable water. Reclaimed water, irrigation, and slurry lines used purple lines. Sewer and drain lines use the color green. A project can be derailed for a long time when these utility lines are hit.
