The Importance of Colors of Underground Utility Lines

Underground utilities can easily be identified today. 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. It is thus important that we know how to identify these underground utilities if there is a need to dig the ground so that you can prevent harm. The OSHA requires that utilities underground first be located before digging through a piece of land. You dont want something disastrous to occur. 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. To prevent these types of incidents, it is important for property owners to call 811 so utility companies can identify their undergoing lines. Utility companies can then mark out their respective lines when you call them out.

But, despite the marks, there will sill be accidents. 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.

With the use of GPR or Ground Penetrating Radar, companies can locate utility lines. This has made it easier to locate utility lies underground and other important things. However, for the ordinary homeowner, it is enough to simply call 811 to be able 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.

If you see white lines, then these are proposed excavation sites. 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.

If you see red lines, then you can be sure that these are electric power lines, cable, conduit, and lighting cables. 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. Natural gas leaks can create potentially disastrous situations and this is why it is appropriate to use the bright yellow color.

If you see orange lines, then you should associate this with communication., alarm, signal lines, cable or conduit. Lines for potable water use blue lines. Purple lines are used for reclaimed water, irrigation, and slurry lines. Sewer and drain lines use the color green. You can derail any project for a long time if you hit these lines.
