  • 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 ...

  • Development of a sealing material and robot for automatic socket rehabilitation of grey cast iron pipes in drinking water supply systems

    The project DeWaLoP, led by Vienna Water, aims to develop a robot that is able to apply a sealing system to repair the joint sockets of pressure operating water pipes measuring about 1 m in diameter. To do this, a modification of the sealing material for inner surface application will be developed and a complex robot system will be designed to perform various tasks, such as inspecting, cleaning ...

  • Multi-sensor inspection robot shows benefits of pipe penetrating radar - Case Study

    Pipe penetrating radar (PPR), the in-pipe application of ground penetrating radar (GPR) is one of the most promising quantitative pipe condition assessment technologies to emerge in recent years. With most of the underground pipe infrastructure reaching the end of their design life there is a need to provide measurable data in order to establish the extent of rehabilitation required or the timing ...

  • Robot procedure: Long-term experience with the KATE procedure

    For some time the topic of the useful life for repair procedures has been a matter of controversial discussion. In the process, giving across-the-board indications of useful life for "repair procedures" has increasingly come to be seen as indefensible. Even when, in addition, a separate approach for different groups of repair procedures - "robot procedures" for example - is suggested, this kind ...

  • Applications of Pipe Penetrating Radar for Advanced Pipe Condition Assessments: the Clark Regional Wastewater District (WA) Case Study

    Abstract Pipe Penetrating Radar (PPR) is the underground in-pipe application of GPR, a non-destructive testing method that can detect defects and cavities within and outside mainline diameter non-metallic (reinforced concrete, vitrified clay, PVC, HDPE, etc.) underground pipes. The key advantage of PPR is the unique ability to map pipe wall thickness and deterioration including voids outside ...

  • Frankfort Electric and Water Plant Board Verifies Distress on Ductile Iron Pipe Using Electromagnetics

    Commercial introduction of ductile iron pipe (DIP) began in the mid-1950s and was established as the most frequently selected material of choice for ferrous pressure pipe by the early 1970s. Due to the widespread use of DIP during a large expansion of pipeline infrastructure in the 1970s, there are many thousands of miles of pressurized DIP in operation today. Water and wastewater utilities ...

  • What’s New? Maximizing The Life Of Aging Metallic Pipelines With Modern In-Line Technology

    Maximizing the life of aging pipelines has long been a challenge in North America. Owners of large diameter water and wastewater infrastructure face particular condition assessment challenges, owing to factors such as financial constraints, environmental concerns and access restrictions, which compound the problem. While desktop studies can help identify pipes with a likelihood and consequence of ...

  • Case study - Washington Suburban Sanitary Commission

    After WSSC began experiencing major PCCP failures in the 1970s, it developed a strong commitment to infrastructure management technology in favor of large capital replacements. Beginning in 2007, WSSC and Pure Technologies began a partnership to create a comprehensive PCCP management program. The Washington Suburban Sanitary Commission (WSSC) is the 8th largest water and wastewater utility in ...
