The Importance of Colors of Underground Utility Lines

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. There is reduced risks today because of new methods of identifying utility lines although not a complete reduction. 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. You dont want something disastrous to occur. The worst thing that can happen if lines are not identified is that fatal injuries can happen. Services in the area where the lines are located can experience interruption. People can call 811 to prevent these incidents, before they proceed with digging their property. When the number is called, you can let the utility companies come out and mark their respective lines.

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.

Companies can locate utility lines through the use of GPR or Ground Penetrating Radar. With this machine, companies can easily locate utility lines. 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. The colors below indicate the kind of utility uses it.

If you see white lines, then these are proposed excavation sites. You can mark areas with white lines that will soon be excavated.

If you see pink lines, they are temporary survey markings. These are used by surveyors to mark off legal property boundaries.

Red lines are used to mark electric power lines, cable, conduit, and lighting cable. 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. Natural gas leaks can create potentially disastrous situations and this is why it is appropriate to use the bright yellow color.

Communication, alarm, signal lines, cable, or conduit use orange lines. If you see blue lines then these are lines for potable water. Purple lines are used 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.
