The Difference Between Public and Private Locating Service

So you’re about to dig or excavate on your property? Removing a tree? Or maybe you’re installing a fence?   Whatever the project is, you hire someone to perform the job. Before they start working, they inform you that they cannot move forward without locating all possible utilities. Maybe you’re about to dig yourself! But before you do, you need to make sure you are avoiding damage to utility lines. And, more importantly, injuring yourself or endangering others.

It is always a wise idea to locate underground utilities before performing any type of digging or excavating on your property. The best approach is to contact 8-1-1 to mark the public utilities. Also, contact a private locator for those private utilities that 811 won’t mark. 811 or public utility locators will not mark any private lines. This is where a private locator, like Penhall Technologies, would step in and complete private utility locating.
