When you’re planning a project that involves digging—whether it’s installing a fence, planting a garden, or laying new pipes—knowing where underground utilities are located is crucial. You might already be familiar with calling 811 before you dig, but did you know that 811 doesn’t cover all underground lines? That’s where private utility locating comes in. Understanding how private utility locating works can save you time, money, and a lot of headaches.
What Are Private Utility Locating Questions You Should Ask?
Before you start digging, it’s important to ask the right questions about private utility locating. Here are some key points to consider:
What is the difference between public and private utility lines? Public utility lines are owned and maintained by utility companies and are marked when you call 811. Private utility lines, however, are owned by property owners or private entities and are not marked by 811. These can include irrigation lines, private electric lines, or underground cables.
Why do I need private utility locating if I already called 811? Because 811 only marks public utilities, any private lines on your property remain unmarked. If you dig without locating these, you risk damaging them, which can cause costly repairs and safety hazards.
How accurate is private utility locating? Professional private utility locators use specialized equipment and techniques to detect underground lines. While no method is 100% foolproof, experienced locators provide the best chance of identifying hidden utilities.
Can I locate private utilities myself? While some homeowners try to locate lines by hand or with basic tools, this is risky and often inaccurate. Hiring a professional ensures a thorough and safe locating process.
How far in advance should I schedule private utility locating? It’s best to schedule locating services well before your project starts. This allows time to address any issues and adjust your plans if needed.
Understanding these questions helps you prepare for your project and avoid unexpected surprises underground.
How Does Private Utility Locating Work?
Private utility locating involves several steps to identify underground lines that 811 does not mark. Here’s a simple breakdown of the process:
Site Assessment
The locator visits your property to assess the area where you plan to dig. They gather information about your project and any known utilities.
Use of Detection Equipment
Locators use tools like electromagnetic locators, ground-penetrating radar (GPR), and radio frequency detectors. These devices help detect signals or changes in the soil that indicate buried utilities.
Marking the Utilities
Once located, the lines are marked on the surface with paint or flags. Different colors represent different types of utilities (e.g., red for electric, blue for water).
Documentation
Some locators provide maps or reports showing the location of private utilities. This documentation can be useful for future reference.
Safety Recommendations
The locator may advise on safe digging practices based on the utility locations.
By following these steps, private utility locating helps you avoid damaging underground lines that could disrupt your project or cause safety issues.
What Does 811 Cover and What Does It Not?
Many people assume that calling 811 before digging covers all underground utilities, but that’s not the case. Here’s what you need to know:
What 811 Does Cover
When you call 811, utility companies mark public underground lines such as gas, water, sewer, electric, and telecommunications lines that they own and maintain. This service is free and required by law before digging.
What 811 Does Not Cover
811 does not mark private utility lines. These include lines on private property that are not owned by utility companies, such as:
- Private irrigation systems
- Underground electrical lines for outbuildings or pools
- Private sewer or water lines
- Underground cables for security systems or lighting
Why This Matters
If you rely solely on 811 markings, you might miss private lines and accidentally damage them. This can lead to costly repairs, project delays, and safety hazards.
Because of these limitations, private utility locating is essential for a complete picture of what lies underground on your property.
How to Prepare for Private Utility Locating
To get the most out of private utility locating, preparation is key. Here are some practical tips:
Gather Any Existing Information
Collect any maps, plans, or records of your property’s utilities. This can help the locator understand what to expect.
Mark Your Dig Area
Clearly mark the area where you plan to dig with stakes, flags, or spray paint. This helps the locator focus on the right spot.
Clear the Area
Remove any obstacles like debris, snow, or heavy vegetation that might interfere with locating equipment.
Communicate Your Project Timeline
Let the locator know when you plan to start digging so they can schedule the service accordingly.
Ask About the Locating Process
Don’t hesitate to ask the locator how they will perform the work and what you can expect.
By preparing properly, you help ensure the locating process goes smoothly and provides accurate results.
What to Do After Private Utility Locating
Once your private utilities are located and marked, here’s what you should do next:
Respect the Markings
Avoid disturbing or removing the paint or flags until your project is complete.
Plan Your Digging Carefully
Use the markings to guide your digging and avoid damaging any lines.
Keep Documentation Handy
Store any maps or reports from the locator for future reference or if you sell your property.
Communicate with Your Contractor
If you’re working with a contractor, share the utility locations with them to ensure everyone is aware.
Report Any Issues
If you notice discrepancies or suspect a utility was missed, contact the locator immediately.
Following these steps helps protect your property and keeps your project on track.

Staying Safe and Avoiding Costly Mistakes
Digging without knowing what’s underground can lead to serious problems. Here are some safety tips to keep in mind:
Never Assume the Location of Utilities
Even if you think you know where lines are, always get a professional locate.
Use Hand Tools Near Markings
When digging close to marked utilities, use hand tools instead of heavy machinery to avoid accidental damage.
Follow Local Regulations
Some areas have specific rules about digging and utility locating. Make sure you comply.
Hire Professionals When Needed
For complex projects or large areas, professional locating services are worth the investment.
By taking these precautions, you protect yourself, your property, and those working on your project.
Understanding private utility locating questions and the process behind it empowers you to dig safely and confidently. Taking the time to locate private underground utilities that 811 doesn’t mark can prevent costly damage and keep your project running smoothly. Whether you’re a homeowner or contractor, knowing what lies beneath the surface is the first step to a successful project.
