Standard Colors for Your Underground Utilities

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. Today, the risks have been lessened although not completely eliminated. If there is a need to dig the ground, it is very important that the utility lines first be identified. The OSHA requires that utilities underground first be located before digging through a piece of land. Otherwise it can be something disastrous. If you hit any of the underground utility lines while digging then you can be fatally injured. 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.

But, despite the marks, there will sill be accidents. 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. These incidents affect public health and safety.

With the use of GPR or Ground Penetrating Radar, companies can locate utility lines. When locating utility lines underground, this machine makes it easy to do so. Companies can locate their utility lines if any property owner calls 811.

Today, utility lines are marked with different colors for easy identification. Below are some of the colors used for different utility lines.

Proposed excavation sites use white lines. You can mark areas with white lines that will soon be excavated.

Temporary survey markings use pink lines. Legal property boundaries are marked off by these pink lines.

Red lines are used to mark electric power lines, cable, conduit, and lighting cable. The color red is perfect for electric works because it is associated with fire and danger.

Yellow lines are used for gas, oil, steam, petroleum, and gaseous materials. The bright color yellow is used to be a warning sign since a natural gas leak can create a potentially disastrous situation.

Orange lines are used for communication, alarm, signal lines, cable or conduit. If you see blue lines then these are lines for potable water. Reclaimed water, irrigation, and slurry lines used purple lines. Sewer and drain lines use the color green. A project can be derailed for a long time when these utility lines are hit.
