Lessons Learned from Years with

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. 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. Fatal injuries can happen if underground utility lines are struck. The location of the areas where the lines were struck can experience service 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.

Sometimes, even if the lines are marked accidents still happen. Utility lines are struck every 6 minutes, some place. When utility lines are stuck it causes disturbances in 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. Calling 811 is enough for the property owner to let companies located their lines.

It is easier to identify underground utility lines today because they now use different colors for each utility. Here are the colors used for different utilities.

If you see white lines, then these are proposed excavation sites. It locates areas that will be excavated in the near future.

Temporary survey markings use pink lines. These are used by surveyors 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. The color red is perfect for electric works because 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.

Orange lines are used for communication, alarm, signal lines, cable or conduit. Lines for potable water use blue lines. Reclaimed water, irrigation, and slurry lines used purple lines. Sewer and drain lines use the color green. Hitting this line can truly derail any project for a long period of time.
