  • 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 ...

  • Comparison of core sampling and visual inspection for assessment of concrete sewer pipe condition

    Sewer systems are costly to construct and even more costly to replace, requiring proper asset management. Sewer asset management relies to a large extent on available information. In sewer systems where pipe corrosion is the dominant failure mechanism, visual inspection by closed circuit television (CCTV) and core sampling are among the methods mostly applied to assess sewer pipe condition. This ...

  • Accepted Inspection Methods of Process Sewers.

    During the process of refining there is discharge of hazardous waste, this coupled with aging pipeline infrastructure creates a potential where waste can leak into the environment posing catastrophic threats to life. Federal agencies such as the EPA are beginning to penalize refineries that do not take necessary measures of disposing their waste. These refineries are subject to ...

  • 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 ...

  • 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 ...

  • Process to Estimate Sanitary Sewer Pipe Remaining Life Provides MWWSSB Remedial Decision Information

    ABSTRACTA condition assessment study for the Water Works and Sanitary Sewer Board of the City of Montgomery’s (MWWSSB’s) West Catoma Interceptor (WCI) was conducted in 1998 and 2003. The WCI was evaluated in 1998 using core sampling, closed-circuit television, and manhole (MH) inspections. Approximately 193 MHs and 65,000 linear feet (LF) of pipe were inspected. A subsequent study conducted in ...

  • Rapid detection of sewer defects and blockages using acoustic-based instrumentation

    Sewer flooding incidents in the UK are being increasingly associated with the presence of blockages. Blockages are difficult to deal with as although there are locations where they are more likely to occur, they do occur intermittently. In order to manage sewer blockage pro-actively sewer managers need to be able to identify the location of blockages promptly. Traditional closed-circuit ...

  • Pipeline Zooming for a Comprehensive Infrastructure Survey.

    Time, budget and resources often keep a municipality from maintaining comprehensive, up-to-date information on water and sewer pipeline conditions. Without a complete understanding of their infrastructures, municipal supervisors cannot properly prioritize and schedule maintenance activities. As a result, emergencies—backups, collapses, and overflows—happen unexpectedly, and must be dealt with on ...

  • Trouble Shooting for Trenchless Liner Installation During Sewer Line Rehabilitation

    ABSTRACTLining is being used by the utility industry as a cost effective solution to rehabilitate utility lines. Many types of liners, such as, cured-in-place-pipe (CIPP), fold and form PVC, deformed & reformed HDPE, etc., are being used to restore structural integrity of deteriorated pipes and to reduce inflow/infiltration. Most of the lining installation is carried out without any problem, ...

  • The Need for a Total View of Water Networks

    The water industry is not short of software offerings, and so the arguments in favour of yet another software program had better be very good indeed. In this article we examine how one very significant community of users – operations managers, engineers and planners - have largely had their specific needs overlooked; we identify the type of system needed to fulfil their requirements and the ...
