The Importance of Colors of Underground Utility Lines

It is now easier to know what an underground utility line is for. The risk was high before when people could not easily identify the type of utility lines underneath whenever they dig. 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. Before digging through a certain piece of land, the OSHA requires that the underground utilities be located. You dont want something disastrous to occur. If you hit any of the underground utility lines while digging then you can be fatally injured. It can also interrupt services in your area where the line is located. To prevent these types of incidents, it is important for property owners to call 811 so utility companies can identify their undergoing lines. Utility companies can then mark out their respective lines when you call them out.

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. These incidents affect public health and safety.

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.

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.

White lines are for proposed excavation sites. It locates areas that will be excavated in the near future.

If you see pink lines, they 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. Lines for potable water use blue lines. Purple lines are used for reclaimed water, irrigation, and slurry lines. Sewer and drain lines use the color green. Hitting this line can truly derail any project for a long period of time.
