Standard Colors for Your Underground Utilities

Underground utilities can easily be identified today. 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. There is reduced risks today because of new methods of identifying utility lines although not a complete reduction. 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. Before digging through a certain piece of land, the OSHA requires that the underground utilities be located. You dont want something disastrous to occur. The worst thing that can happen if lines are not identified is that fatal injuries can happen. The location of the areas where the lines were struck can experience service interruption. People can call 811 to prevent these incidents, before they proceed with digging their property. Calling the 811 number will enable utility companies to come out and mark their respective utility 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.

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. However, for the ordinary homeowner, it is enough to simply call 811 to be able to let companies located their lines.

Today, utility lines are marked with different colors for easy identification. Here are the colors used for different utilities.

White lines are for proposed excavation sites. Area that will be excavated in the future are marked.

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.

If you see yellow lines, then they are lines for gas, oil, steam, petroleum, and gaseous materials. Natural gas leaks can create potentially disastrous situations and this is why it is appropriate to use the bright yellow color.

Orange lines are used for communication, alarm, signal lines, cable or conduit. If you see blue lines then these are lines 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. A project can be derailed for a long time when these utility lines are hit.
