Why a private utility locating service?

Subsurface utility lines represent one of the most common risks to excavation crews and one of the biggest unnecessary expenses for construction jobs. You are required by law to locate and avoid any subsurface utilities located on your job site before beginning any excavation project. Normally, this process starts by calling your local 811 state utility locator. But they are only required to locate public utility lines, providing you with an incomplete picture, putting your job and your team at risk.

811 Locating services only covers underground public utilities, and does not cover private utilities. For residential customers, private utilities may include gas lines for a heated pool, electric lines for a shed, garage, or barn, and certain sewers. For commercial customers, private utilities may include parking lot lighting, fire mains, and building-to-building utilities. All of these lines will be your responsibility if damaged or severed during the course of your excavation!
