Ensure Safety and Avoid Private Utility Damage

Before you or your contractor begins excavating for your project, it is absolutely essential that you locate all utility lines within the site first. Otherwise, you might accidentally damage them, leading to serious legal and financial consequences.

If you accidentally damage an electrical or gas line, for example, you would have to pay for the damage. The consequences may be even more severe if you damage a line servicing a hospital or emergency call center. And in some cases, you would also be at risk of injury.

Locating public utility lines is easy. You just have to call 811. However, they won’t mark the location of private lines. For that, you need Minnesota Irrigation’s services for locating private underground utilities. Our team of expert technicians will accurately mark private lines to ensure your safety.

Our private utility locating service marks underground utilities that are not owned by the utility companies and therefore are not located through the Gopher State One Call process.

  • Any utility that connects to a building from the “master meter”
  • Electrical lines to: parking lot lights, lighted signs, remote outlets
  • Connection to a direct lead

Fault locating finds grounded shorts (nicks) or opens (breaks) in private electrical lines. A grounded fault is when the damaged wire makes direct contact with the ground.

  • Both ends of the faulted electrical line must be disconnected by the homeowner or contractor.
  • The wires are tested to find faulted wire or wires
  • The fault is located
  • Once a fault is located it is dug up by the homeowner or contractor, the wires are cut and both ends are stripped. The wires are re-tested in both directions
  • The testing and fault locating continues until all faults are located
  • It is the responsibility of the homeowner or contractor to repair the faults.

We also offer irrigation zone valve and pinched irrigation pipe locating services.

Choose a Trusted and Reliable Company

There are several reasons accidents happen during excavation, and many of them are rooted in inaccurate information. A utility locating contractor might incorrectly estimate the depth of a line, or they might be unsure of the depth and direction of two overlapping lines.

That’s why you need to be careful when choosing your utility locating contractor. You need a company that will give you accurate and reliable information.
