  • The Importance of Wastewater Force Main Management

    Condition assessment and management of wastewater force mains has historically been challenging for operators. Conventional methods (e.g. visual inspection, sonar and laser profiling) do not provide a comprehensive condition assessment because they do not quantify the loss of structural capacity. As WEFTEC 2013 in Chicago approaches, ...

  • Exploring the need for rainwater tank maintenance: survey, review and simulations

    Rainwater tanks are a common feature of the urban landscape in Australia and globally. In Brisbane, Australia, provision of alternative water in new homes is mandatory and to meet this requirement rainwater tanks are considered an important option. The water savings of rainwater tanks can help defer investments in supply infrastructures. An emerging concern is that there is currently no ...

  • Comparing the utility of decision trees and support vector machines when planning inspections of linear sewer infrastructure

    Closed-circuit television inspection technology is traditionally used to identify aging sewer pipes requiring rehabilitation. While these inspections provide essential information on the condition of pipes hidden from day-to-day view, they are expensive and often limited to small portions of an entire sewer system. Municipalities may benefit from utilizing predictive analytics to leverage ...

  • Pipeline infrastructure renewal at Miami-Dade Water & Sewer Department

    Abstract Various governmental, professional and private studies have shown that the replacement costs of underground pipeline infrastructure is excessive and that best practice approaches for infrastructure risk management promote condition assessment programs to understand the actual condition of individual pipe sections in order to best allocate limited capital replacement and ...

  • 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 ...

  • 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 ...
