How to find and recognize underground utilities

Utility location is a method for labeling and classifying of underground public service channels. Examples of these networks service are electricity distribution, wastewater pipes, and water mains, storm drains, traffic signal, cable television, lines for telecommunication, fiber optics, street lights. In some places, national defense communication lines, gas pipelines, and oil, mass transit, road and rail tunnels compete for underground spaces.

What are the most common methods for finding underground utilities?

2-man electromagnetically wiping
The use of 2 man Inductive Electromagnetic Scanning method can help to locate utilities without past experience of the buried facilities. This was done by a team of two men, the first one with a transmitter and the other one with a receiver. If they encounter the metallic utility at the same time, they will recognize and also mark it, and then follow it. Since each analysis can only be reliably detected that underground objects of angles up to 90 degrees to 360 degrees, four scans or different scan angles must be executed throughout the search box in order to optimize the efficiency of the process.


Place of electromagnetic system
Electromagnetic utility locating is the best method for finding private utilities. In this system, the locating equipment produces electromagnetic radio frequency and, when fitted to the ground, underground utilities comprising the conductive material will be identified on the receiver. This system is very reliable and is often used to propane, electric, cable, telephone, sewage, detect gas, water, irrigation line, and storms.
Gas lines are usually made of medium or high-density polyethylene plastic or pipe, this the main reason why tracking wire is usually passed along the pipeline just to make the line more “locatable”. In such situations, having access to the system example is (a tracer wire box)), the current can be caused on the trace wire in order to locate the tracer wire.
This technology does not work well above the base of 10 to 15 feet. Natural gas distribution lines are normally fixed at a base of 3 to 4 feet, while the transmission lines are deeper, but it would be unusual to install more than 10 feet.


Ground Penetrating Radar
Ground penetrating radar is a geophysical system that utilizes radar pulses to capture the underground. This non-destructive system makes use of electromagnetic radiation waves to discover signals that are reflected from underground structures. The GPR device system is also an important tool in the Underground Detective arsenal, which requires a long-term experience to correctly evaluate the results.
Ground penetrating radar (GPR) is used in odd jobs, but the most usual calls we receive demand help with locating and searching for:

  ♣ Underground storage tanks (UST)
  ♣ Concrete scanning
  ♣ Trenches
  ♣ Vacuum Excavation
  ♣ Grave sites
  ♣ Metallic and non-metallic pipes


Vacuum excavation is also one of the modern technologies for digging the terrain. It uses kinetic energy in the flow of large air currents to penetrate, expand and break down the soil for underground excavation. Compared to shovel and water, the air quickly and efficiently performs heavy excavation tasks, increases production, and reduces costs. These advantages, combined with increased operator safety and utility, make the air aspirator an ideal choice for the needs of the Underground Detective excavation. Vacuum excavation is used for the following services:

  ♣ Checking underground services
  ♣ Utility Line Service Terminations
  ♣ Remove the drill hole in the environment
  ♣ Remote Excavation (Inside buildings)
  ♣ Cleaning the valve box and Catch Basin
  ♣ Vertical, horizontal accuracy, size, and type of read-before-job readers
  ♣ Potential methods


Potential methods can be used to detect buried metal objects, such as pipelines and reservoirs, with contrast magnetite content. Methods based on potentials include magnetic and gravimetric potential.


All about HIGP Research Institution

By admin /

Hawai’i Institute of Geophysics and Planetology (HIGP) is among the world developing multi-disciplinary institute that conducts advanced research, teaching, workforce training, technology development and also service in the oceanographic cutting edge, geological, engineering, atmospheric, planetary science and geophysical. HIGP is part of SOEST University of Hawai at the Manoa campus. We house around 100 faculty members, postdoctoral researchers, staff and also graduate students who have access to different instrumentations and state of art laboratories, far-ranging field sites, and research vessels. We have corporation through the Space Flight Laboratory of Hawai with the College of Engineering for launch and satellite fabrication. The expertise of our institute has spanned the world at all places right from the upper atmosphere to deep Earth interior and we have extensions to other planets like Mars, and to the moon.

University Promotion and Tenure Announcements

It is with great pleasure to put on board the announcement the tenure with promotion to Bin Chem, an Associate Researcher in the Mineral Physics research and also the tenure of the institution’s Associate Researcher, Hope Ishii and also the Director of the Center of Advanced Electron Microscopy.

Updates for the Geothermal Resources Center and Hawai Groundwater (HGGRC) La Island Project

The institution researcher Don Thomas, HIGP Associate Researcher Nicole Lautze and the entire HGGRC project team have made way to post updates concerning the ongoing HGGRC research water project on La. This is actually an assessment of hydro-geo-chemical groundwater systems that have commenced in the great Pai Basin.

Both the newly developed and historical information that relates right to the geothermal and groundwater resources all over Hawai am found at the online repository of HGGRC. All that HGGRC is struggling to do is increase access to data that regards all the existing resources, put in place encouragement for innovations and research in both the geothermal energy and water management, to give the public such an informational platform, and also the ensure they supply the required information to policymakers so that they can maximize utilization of the natural resources of Hawai.

Mission Statement from HIGP

The institution of HIGP has made it solve important problems in planetary science and Earth simply by application and development of data analysis technologies via a software company, state-of-art exploration and also clear measurements. HIGP institution stands to serve both the State of Hawai and the society by simply disseminating and acquiring new knowledge about other existing planetary bodies and the Earth, and also introducing and developing all the possible leading edge technologies and state economy highly experienced workforce.
