  • Completing Condition Assessments using In-pipe GPR as Pipe Penetrating Radar

    Abstract This paper describes the development of Pipe Penetrating Radar (PPR), the underground in-pipe application of GPR, a non-destructive testing method that can detect defects and cavities within and outside mainline diameter (>18 in / 450mm) non-metallic (concrete, PVC, HDPE, etc.) underground pipes. The method uses two or more high frequency GPR antennae carried by a robot into ...

  • Combined application of Pipe Penetrating Radar and LIDAR for large diameter pipe inspection

    Abstract: Pipe Penetrating Radar (PPR) is the underground in-pipe application of ground penetrating radar (GPR), a non-destructive testing method that can detect defects and cavities within and outside mainline diameter (>18 in./450mm) non-metallic (reinforced concrete, vitrified clay, PVC, HDPE, etc.) underground pipes. Light Detection and Ranging (LIDAR) has become an accepted method for ...

  • GPR goes underground: Pipe Penetrating Radar

    Abstract: Pipe Penetrating Radar (PPR) is the underground in-pipe application of ground penetrating radar (GPR) either robotically or by manned entry to reveal wall thickness, delamination, voids, and other conditions that enable more precise determination of pipeline integrity and verifications for trenchless technology rehabilitation. PPR, when applied to pipe-bursting applications, can be ...

  • XT512 Portable Locator, the best Tool to precisely locate the inspection camera head

    One of the huge benefits of visual remote pipe inspections is being able to visualize problems, so you know exactly what to expect when going in to repair something. Underground pipes are especially susceptible to leaks and roots causing problems in hard to reach places. One problem with traditional pipe inspection equipment is while you can visualize the problem inside the pipe, it can be hard ...

  • An electromagnetic-based method for pinpointing leaks in buried pipes: a practical validation

    In this paper, a time domain reflectometry (TDR)-based solution for detecting water leaks in underground pipes is described and experimentally validated. The proposed method strongly reduces the inspection time that is typically required by traditional leak detection methods. In fact, it can successfully inspect pipes that are hundreds of meters long. In this work, two different configurations ...

  • Info-Gap robustness pathway method for transitioning of urban drainage systems under deep uncertainties

    In the urban water cycle, there are different ways of handling stormwater runoff. Traditional systems mainly rely on underground piped, sometimes named ‘gray’ infrastructure. New and so-called ‘green/blue’ ambitions aim for treating and conveying the runoff at the surface. Such concepts are mainly based on ground infiltration and temporal storage. In this work a methodology to create and ...

  • RegenOx™ treats petroleum hydrocarbons surrounding sensitive underground infrastructure at a defence facility

    Former fueling operations at Scott Air Force Base resulted in soil contamination containing high levels of benzene, ethylbenzene, methyl tertiary-butyl ether (MTBE), and naphthalene. Underground storage tank removal and source area excavation were planned to treat the unsaturated soil. However, subsurface investigations revealed piping, fiber-optic communication lines and other utilities present ...

  • On the prediction of underground water pipe failures: zero inflation and pipe-specific effects

    The prediction of pipe failures in water distribution systems is an essential planning tool for water companies. Previous methods focus on the prediction of either future failure numbers or aspects of pipe condition. However, most of these only predict at the level of large pipe groups (of similar characteristics) and often cannot provide uncertainty bounds. Here, a new statistical method is ...
