Undergoung Utilities and their Standard Colors

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. If you need to dig through a piece of land today, you are required by the OSHA to first identify or locate underground utilities. You dont want something disastrous to occur. 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. To prevent these types of incidents, it is important for property owners to call 811 so utility companies can identify their undergoing lines. 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. It is said that every 6 minutes, there is a utility line that is struck. Traffic lights, wastewater pipes, telecommunication lines, etc. are affected when lines are struck. Public heath and safety is affected when this happens.

Companies can locate utility lines through the use of GPR or Ground Penetrating Radar. With this machine, companies can easily locate utility lines. Companies can locate their utility lines if any property owner calls 811.

Today, utility lines are marked with different colors for easy identification. Here are the colors used for different utilities.

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

If you see pink lines, they are temporary survey markings. Legal property boundaries are marked off by these pink lines.

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 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. The bright color yellow is used to be a warning sign since a natural gas leak can create a potentially disastrous situation.

If you see orange lines, then you should associate this with communication., alarm, signal lines, cable or conduit. If you see blue lines then these are lines for potable water. If you see purple lines, that this is for reclaimed water, irrigation and slurry lines. If you see the color green, then it indicates sewer and drain lines. Hitting this line can truly derail any project for a long period of time.
