Undergoung Utilities and their Standard Colors

It is now easier to know what an underground utility line is for. However, a long time ago, it was difficult to identify these utility lines and so when people try to dig there were many risks involved. Although not completely eliminated, risks today have been reduced. If there is a need to dig the ground, it is very important that the utility lines first be identified. Before digging through a certain piece of land, the OSHA requires that the underground utilities be located. Otherwise it can be something disastrous. If you hit any of the underground utility lines while digging then you can be fatally injured. Services in the area where the lines are located can experience interruption. 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.

Marking lines may lessen the risks but there are time when accidents still happen. Utility lines are struck every 6 minutes, some place. When this happens, it affects traffic lights, wastewater pipes, telecommunication lines and more. This is then something that affects public health and safety.

Companies can locate utility lines through the use of GPR or Ground Penetrating Radar. This has made it easier to locate utility lies underground and other important things. Companies can locate their utility lines if any property owner calls 811.

Today, utility lines are marked with different colors for easy identification. The colors below indicate the kind of utility uses it.

Proposed excavation sites use white lines. Area that will be excavated in the future are marked.

Temporary survey markings use pink lines. These are used by surveyors to mark off legal property boundaries.

Electric power lines, cable, conduit, and lighting cable use red lines. The color red is associated with fire and danger so it is just appropriate to use it for electrical works.

If you see yellow lines, then they are lines for gas, oil, steam, petroleum, and gaseous materials. Bright yellow is an appropriate warning color since it is very disastrous to have a natural gas leak.

Communication, alarm, signal lines, cable, or conduit use orange lines. Lines for potable water use blue lines. Reclaimed water, irrigation, and slurry lines used purple 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.
