Deciphering Utility Markings
What are Utility Markings?
Utility markings are a type of visual coding system used to identify underground utility lines. These markings are typically painted onto the ground or set up as small flags, with different colors denoting different types of utilities.
The Color Coding System for Utility Markings
The American Public Works Association (APWA) has established a color code for utility markings, a system utilized nationwide to facilitate easy identification of utility lines beneath the surface of any construction site. Here is what each color signifies:
| Color | Utility |
|---|---|
| Red | Electric power lines, cables, conduit and lighting cables |
| Yellow | Gas, oil, steam, petroleum or gaseous materials |
| Orange | Communication, alarm or signal lines, cables or conduit |
| Blue | Potable water |
| Green | Sewers and drain lines |
Not Just Colored Markings
It’s important to note that utility markings also include various symbols and letters to provide additional data such as the size of the pipe or cable, the direction of the line, and more. As a general rule, lines are used to denote the path of the utility, while letters indicate the type of utility, and numbers provide additional information.
The Significance of Using Utility Markings
Utility markings are important in construction and excavation projects:
- Safety: They help prevent damage to utility lines, which might lead to accidents and disrupt services.
- Efficiency: Markings ensure excavations are done correctly the first time, reducing unnecessary work and potential delays.
- Compliance: Following the marking code is a legal requirement, as it prevents potentially costly violations and fines.
Utility Marking Process
Before excavation starts, a professional locator will use special tools to determine the type and location of underground utilities and mark them accordingly. As a best practice, one should always reach out to a local one-call number or “Dig Safe” system to have all underground utilities marked prior to starting a digging project.

The Cost of Having Utility Lines Marked
Why Mark Utility Lines?
Marking utility lines is a necessary step before starting any excavation or construction project. It helps prevent damage to underground utilities, which could lead to service disruptions, costly repairs, or potentially dangerous situations.
Cost of Utility Line Marking
The cost of having utility lines marked can vary, but in many places across the United States, it is free for homeowners and contractors. Here’s a breakdown:
- Free Service: Organizations like “Call Before You Dig” or “811” provide free utility marking services as a public safety measure. This ensures that property owners and contractors have safe digging guidelines.
- Private Locating Services: If utility companies are unable to mark certain private lines, property owners might need to hire private locating services, which can cost anywhere from $100 to several hundred dollars, depending on the project size and location.
- Additional Costs: If you’re involved in larger projects or need expedited services, additional fees might apply. It’s advisable to inquire about any potential costs directly with service providers for accuracy.
Why Utility Marking May Be Free?
Utility marking is often free due to its important role in preventing utility damages:
- Public Safety: Properly marked utility lines reduce the likelihood of accidents, such as gas leaks or electrical outages, which can impact public safety.
- Damage Prevention: Utility companies save money by preventing breaks and repairs, so they often absorb the cost of marking to avoid more expensive problems.
- Legal Requirement: In some areas, it is legally required to notify utility companies before digging, so free marking services encourage compliance with these regulations.
How to Request Utility Marking?
To get utility lines marked, the process includes:
- Contact 811 Before Digging: Dialing 811 connects you to a local “call before you dig” center. This service schedules a professional to visit your site to mark the utilities.

Is Utility Marking Paint Permanent?
Understanding Utility Marking Paint
Utility marking paint is a specific type of paint used to delineate locations of underground utility lines during construction projects. It provides temporary guidance to excavators and other workers to avoid damaging subterranean utilities.
Characteristics of Utility Marking Paint
Utility marking paint does not have lasting properties. Here are some key characteristics:
- Temporary Nature: The paint used for utility marking is designed to fade over time. Typically, it lasts anywhere from a few weeks to a few months, depending on environmental conditions such as rain and foot or vehicle traffic.
- Visibility: Marking paint is bright and highly visible, often fluorescent, to ensure markings are easily seen by workers and site personnel.
- Weather Resilience: While not permanent, the paint has some resistance to immediate weather conditions such as light rain or wind, ensuring it remains visible for the short term needed during excavation.
Why Temporary Paint is Used
The temporary nature of utility marking paint serves several purposes:
- Project-Based Usage: The markings need to be visible only for the duration of a particular project or until excavation is complete, after which they naturally fade away, minimizing long-term visual pollution.
- Environmental Considerations: Temporary paints are generally formulated to be environmentally safe so that they do not stay on the landscape permanently or harm local flora and fauna.
- Ease of Removal: If removal is necessary, temporary paints can be washed away with water or fade due to environmental factors without leaving permanent marks on the surface.
Alternatives to Painting
For longer-lasting identification, alternatives to marking paint are available:
- Flags: Small, bright flags are often used in combination with paint to mark utility lines, offering a different visual cue that can be easily moved or replaced as needed.
- Signage and Barriers: Temporary signs or physical barriers can also be used, especially in areas of high pedestrian or vehicle traffic, to denote the presence of underground utilities.
- Digital Mapping: As technology advances, digital maps are increasingly used to track and manage utility lines. These can be accessed via smart devices on-site, offering real-time updates and reducing the need for physical markings.
