Private Utility Locating

gpr detection below roadWOOD Inspection Services deploys traditional (EM) location equipment for the initial detection of visible utilities. Our team marks these lines with paint using the standard colors as defined by the Americas Public Works Association.

To be comprehensive, we scan the area with Ground penetrating radar for any signs of utilities or obstructions which should be avoided during excavation, digging or drilling. The data for is collected in a grid format which provides full coverage of the survey area and allows for unknown objects to be discovered. Next, a 3D map of the ground and its infrastructure can be developed. This is especially beneficial in congested areas for identifying utilities and also for pre-engineering purposes.

Utility Mapping and Surveying

Electromagnetic Locating (EML)

EML involves using electromagnetic technology to locate metallic and non-metallic utilities such as water, gas, and electric lines. EML can be performed on both conductive and non-conductive materials.

Ground Penetrating Radar (GPR)

GPR  utilizes high-frequency radar to locate buried utilities and structures. GPR is highly effective in identifying non-metallic objects such as plastic and concrete pipes.

Utility Verification

This involves verifying the existence and location of underground utilities that have been previously identified or mapped. This is typically performed prior to construction to ensure that utilities are properly located and avoid costly conflicts during the construction process.

SUE (Subsurface Utility Engineering) Services

Our SUE (Subsurface Utility Engineering) services  locate and map underground utilities like gas, water, and electric lines. There are four levels of SUE, each with varying degrees of accuracy and cost.

  • Quality Level A (QL-A)
  • Quality Level B (QL-B)
  • Quality Level C (QL-C)
  • Quality Level D (QL-D)

Always Call Texas811

Call the public locator service in Texas, known as the the One-Call System (DIGTESS or 811). Do it before you dig, blast, bore, trench, drill, grade, or excavate underground in any way. If you hit a buried utility line, you could create a life-threatening situation and be fined and cause an outage to an essential utility service. Even if you have used the service before and you think you know where the underground utilities are, contact 811 before every digging project to protect yourself. Remember, it is a free service.

What Does the Public Locating Service Do?

Texas811 does not mark utilities, but instead notifies participating member utilities. In a few days, a representative of the utility will visit the property, locate and mark primary public utility lines (water lines, natural gas pipelines, electric). Before a visit to your property, white-line where you plan to dig, locators can more easily mark the affected utilities.

A reminder that utility maps are not updated often and the markings may be off. Texas811 has the most current, most accurate information about buried utilities.

Private vs. Public Utility Locating Companies

Understanding the difference between public and private utilities can be crucial when it comes to underground locating. Public utility services are those that end at the street, while private utilities are located between the meter and the building. It is important to note that Texas811 will not mark private or non-member utilities, which means that if you have a curbside meter or private utility lines, your property may not be marked for excavation. Other underground utilities that are generally not marked include sewer lines, private lighting, sprinkler systems, fire mains, secondary electric lines to detached garages, pools, and septic lines.

To ensure that all of your underground utilities are properly located and marked, it is important to contact an independent utility contractor like WOOD Inspection Services. Our team of experts can provide a comprehensive evaluation of both private and public utilities, as well as any unused lines on your property. We understand the importance of avoiding costly and dangerous mistakes during excavation, and we are committed to providing reliable and accurate information to help keep you and your property safe.
