PRIVATE LOCATING: Locating the Underground Lines You Own

Are you planning on running electricity to your garage or shed? Installing an underground sprinkler system? Digging up or extending the parking lot for your office building or restaurant? In order to do any of these things — or numerous other construction projects — safely, you have to find out where your utility lines are buried. But it's important to understand that the utility lines are only owned by the public utility companies up until a certain point. After that, those lines are owned by you or the property owner and are your responsibility.Iin order to make sure that your construction can proceed with the correct precautions taken, you need to know the exact location of the existing lines on your property. Public utility companies are notified by the One Call Center , so that they can protect their facilities from damage and service interruptions; but they will only mark the public utility lines, not the ones that are privately owned.

At One Call Concepts, we have decades of experience performing utility locating for public utility companies and private entities.

To have the underground lines that are not owned by the utility company found and marked, you must mark the location yourself or hire a contract locating company to perform this service for you. Our experience can help you avoid damage to your lines and keep you safe. Whether you are a homeowner or a contractor working on a residential or industrial site, in situations where private lines exist, you can call on OCCLS to mark the private utilities in your project area.

Public utilities responsibility (or ownership) typically stops at the metering point.

Once that metering point is encountered, the lines may change ownership. Here's a list of common places where that ownership transfer occurs.

The transfer of public and private responsibility is assumed in some typical places. For example, if you are contemplating a parking lot change, the streetlight wires may be owned by the public utility, but the parking lot lighting wires may not be. Similarly, the electric, water, and communications lines that run from your home to other structures on your property — the garage, guest house, barn, workshop, or pool house — are yours.

It's your responsibility to make sure that any work done on your property can proceed safely.

Here's how to get started finding your lines.

Just email us at or call us at (410) 712-0202. Either way, you'll reach our knowledgeable staff, who will guide you through the simple process:

  1. We will set up a meeting.
    A locating technician will meet with you to discuss the area to be marked and explain the procedures we use to find your lines.

  2. We will ask about any utility plans or records you may have, even if they're not documented.
    Sometimes plans or records never existed or are lost; in those cases, we can start with what you remember. Should you have any records of the existing underground lines or recollection of what is buried in the area, the technician will use this information to find and account for the underground utilities in question.

  3. We will mark the lines.
    The marking of the lines will be done once the technician is confident he has accurately traced the path of the underground utility. Various methods will be used to find the lines. The method used will be determined by several factors, such as soil condition, availability of a grounding point, the type of utility and its composition.
