Underground Utility Survey Laboratory (ZS1007)

The lab mimics a scale-down underground utilities network (water, drains, sewer, electric, gas) to simulate the congested utilities environment and hazards in congested cities. Near-surface and nondestructive geophysical technologies are used for imaging and diagnosis, such as ground penetrating radar, electromagnetic pipe cable locator, acoustic leak noise correlator, infrared thermography, etc.
Students learn and are given chances to test their imaging and diagnostic competence in this indoor and relatively easy underground environment for better preparation of conducting the same task in the more complex and realistic underground.
