Choose the Service That Fits Your Job
EM Utility Locating
Electromagnetic locating is often the best starting point when a buried private utility is conductive and has a usable access point for tracing. This can apply to certain underground electrical lines, communication lines, and some private water services where the route can be followed with the right setup.
If your job involves locating a traceable private line before digging, this is often the most direct service to request. You can also learn more on the Electromagnetic Locating page if you want a fuller explanation of when this method makes sense.
GPR Utility Scan
Ground penetrating radar is useful when the underground layout is uncertain, the utility may be non-conductive, or standard tracing alone is not likely to answer the question. GPR is often requested when the concern is not just one known line, but whether other buried utilities or subsurface features may also be present in the work area.
This is a strong option for properties with unclear utility history, limited access points, or more complex work areas. You can also review the GPR Locating page for more detail on when GPR is the better choice.
Sewer Scope and Sonde Locating
Sewer sonde and camera locating is used to help trace sewer laterals and better understand their route from a structure toward the connection point. This is often helpful before sewer repairs, replacement planning, tie-in work, or excavation near an existing sewer line. It does require an accessible cleanout, usually found outside the home.
If the main question is where a sewer lateral or drain line runs, this is usually the service to review first. You can also visit the Sewer Scope and Video page for more detail about this type of locating.
Magnetic Locating
Magnetic locating can help identify certain buried metallic objects and underground features when other locating methods are not the best fit for the job.
If the project involves finding a buried metallic object or underground feature rather than tracing a standard utility route, this is the most relevant service to review. You can also learn more on the Magnetic Locating page.

Not Sure What to Book?
A lot of customers know what they are trying to avoid hitting, but do not know which locating method makes the most sense. That is normal. Some jobs are a good fit for electromagnetic locating, some call for GPR, and some may require sewer sonde locating or a combination of methods depending on the property and the type of buried utility involved.
If you are unsure, review the main Services page for a broader breakdown of each locating method. You can also review the Pricing page to understand starting rates before sending a booking request.
Common Reasons People Book a Locate
Before Fence Installation
Fence installation is one of the most common reasons people request private utility locating. Post holes and gate areas can cross buried private lines even when the project seems simple.
Before Trenching or Excavation
A booking request often starts with trenching, drainage work, utility replacement, grading, or excavation planned somewhere on private property. The goal is to get a better idea of what may be underground before work starts. Hiring Trent with Twin City Locating can help reduce or eliminate the risk of striking an underground utility.
Before Sewer, Water, or Electrical Work
Many customers request locating before working around a sewer lateral, private water line, underground electrical feed, irrigation system, or communication line. Even when the general direction seems known, the exact route is not always clear enough to dig confidently.
Before Construction or Property Improvements
Bookings are also common before garages, shops, outbuildings, ADUs, patios, retaining walls, driveways, and other property improvements where buried lines may cross the work area.

What to Include in Your Booking Request
The most helpful information to include is the property address, what kind of project is being planned, where on the property digging will happen, and what type of utility or buried line you are trying to locate.
That could involve a sewer lateral, private water line, underground power, irrigation route, communication line, or a broader need to understand what may be in the work zone before excavation begins.
