Why Properties Require
Private Utility Locating

One of the biggest problems facing construction companies today is the issue of locating and marking private utilities. Underground utilities, such as water and sewer lines, gas lines, and electrical cables, are often not accurately marked, leading to expensive damage during excavation. 

Inaccurate utility locates are often the result of poor record keeping, and they can have a significant impact on a construction project. Not only does it cost money to repair the damage, but it can also cause delays and disruptions.

The best way to avoid this problem is to understand the local area and the utility infrastructure well.

Hire Professionals

Anyone who has ever dealt with a utility issue on their property knows how frustrating it can be. Trying to figure out where the problem is coming from can be a real challenge, especially if you don’t have any experience with utilities.

Don’t even attempt to do the work yourself. Utility locating and leak detection require specific equipment and expertise.
