Standard Colors for Your Underground Utilities

If you find underground utilities, you can easily determine what type of utility it is for. 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. Today, the risks have been lessened although not completely eliminated. 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. Otherwise it can be something disastrous. Fatal injuries can happen if underground utility lines are struck. The location of the areas where the lines were struck can experience service interruption. To prevent these types of incidents, it is important for property owners to call 811 so utility companies can identify their undergoing lines. 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. Traffic lights, wastewater pipes, telecommunication lines, etc. are affected when lines are struck. Public heath and safety is affected when this happens.

With the use of GPR or Ground Penetrating Radar, companies can locate utility lines. With this machine, companies can easily locate utility lines. 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. Below are some of the colors used for different utility lines.

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

Temporary survey markings use pink lines. 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.

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. Green lines are used for sewer and drain lines. A project can be derailed for a long time when these utility lines are hit.
