When you plan to dig on your property, knowing what lies beneath the surface is crucial. Buried utility lines can pose serious risks if damaged. This is why understanding the private utility locating process is essential. It helps you avoid costly repairs, service interruptions, and safety hazards. I will guide you through the steps involved, explain what to expect, and share practical tips to make the process smooth and effective.
What Is the Private Utility Locating Process?
The private utility locating process involves identifying and marking underground utility lines that are not covered by public utility locators. These lines belong to property owners or private companies and include things like water lines, sewer pipes, gas lines, and electrical cables that run within your property boundaries. Typically, everything that is past the meter is considered privately owned.
The process starts with a request to a professional locating service, such as Twin City Locating. Using specialized equipment to detect and mark the location of these utilities. This helps you know exactly where it is safe to dig. With approximate depths, can help the excavator with how to safely navigate around or near the identified utility. There are a few methods of use, and every scenario is unique.
Here’s a simple breakdown of the steps:
Request a Locate Service - Contact a trusted private utility locating company. Provide details about your property and the area where you plan to dig.
Review Utility Maps - The locator reviews available maps and records to understand what utilities might be present. Property owners are vital to help understand the area and what to look for.
On-Site Detection - Using tools like electromagnetic locators and ground-penetrating radar, the technician scans the area.
Marking Utilities - Once detected, the lines are marked on the ground with color-coded flags or paint, or white and pink paint.
Report and Advice - You receive a report detailing the locations and any recommendations for safe digging.
This process is vital because public services like 811 only mark public utilities. Private lines remain your responsibility to locate and protect.

Why You Should Understand the Private Utility Locating Process
Understanding this process helps you take control of your project and avoid surprises. Here are some reasons why it matters:
Safety First: Striking a gas or electrical line can cause injuries or worse. Knowing where these lines are keeps you and your workers safe.
Avoid Costly Repairs: Repairing damaged utilities can be expensive and time-consuming. Locating them beforehand saves money.
Stay Compliant: Some local regulations require private utility locating before digging. Knowing the process helps you meet these rules.

If you want to avoid the stress and risks of accidental utility damage, learning about this process is a smart step.
What is a private utility example?
A private utility example includes any underground service line that is owned and maintained by a property owner or a private company rather than a public utility. For instance, the water line that runs from the city meter to your house is considered a private utility once it exits the meter. Similarly, underground electrical cables that supply power to your home from a private transformer or municipal power meter, or septic system pipes are also private utilities.
These lines are not marked by public utility locators when you call 811. That’s why you need a specialized service to locate and mark them before you dig.
Here are some common private utilities you might encounter:
Water service lines from the meter to your home
Sewer and septic system pipes
Private gas lines serving your property, such as an outdoor grill or pool.
Underground electrical cables on your land, such as outbuildings, wells, or yard lights.
Irrigation system piping
Knowing these examples helps you understand what to expect during the locating process and why it is necessary.

How to Prepare for a Private Utility Locate
Preparation is key to a successful locating service. Here’s what you should do before the technician arrives:
Clear the Area: Remove any debris, vehicles, or obstacles that might block access to the digging site.
Mark Your Dig Site: Use stakes, flags, or spray paint to outline where you plan to dig. This helps the locator focus on the right area.
Gather Property Information: Have any maps, previous locate reports, or utility bills handy. This information can assist the technician.
Notify Neighbors: If your digging is near property lines, inform neighbors to avoid confusion or conflicts.
Schedule in Advance: Book your locate service early to avoid project delays.
When the technician arrives, they will perform a visual inspection, speak to the customer onsite for details, and then use their equipment to detect underground lines. They will mark the utilities as needed, and provide depths that are accessible for privately owned utilities.
Remember, the locate marks are your guide. Avoid digging within the marked zones or use hand tools carefully if you must work near them.
What to Expect During and After the Locate
During the locate, the technician will:
Walk the marked area scanning with detection tools
Mark the location of any private utilities found
Explain the markings and answer your questions
Provide a written report or map showing the utility locations
After the locate, you should:
Review the markings carefully before digging
Follow any safety recommendations given
