  • 5 Considerations for Choosing Pipe Bursting

    Homeowners who encounter sewer, drain, and water line problems often dread repairs not just because of the expense, but the major disruptions that they expect. Excavation, torn up lawns, and days of going without water are associated with traditional methods of repair. Fortunately, technology has made it possible to assess and fix pipes with minimal disruption by using a technique called pipe ...

  • Valuing information for sewer replacement decisions

    Decision-making for sewer asset management is partially based on intuition and often lacks explicit argumentation, hampering decision transparency and reproducibility. This is not to be preferred in light of public accountability and cost-effectiveness. It is unknown to what extent each decision criterion is appreciated by decision-makers. Further insight into this relative importance improves ...

  • Multivariate probability distribution for sewer system vulnerability assessment under data-limited conditions

    The lack of geometrical and hydraulic information about sewer networks often excludes the adoption of in-deep modeling tools to obtain prioritization strategies for funds management. The present paper describes a novel statistical procedure for defining the prioritization scheme for preventive maintenance strategies based on a small sample of failure data collected by the Sewer Office of the ...

  • 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 ...

  • What`s in the numbers? a review and analysis of more than 400 miles of force main inspection and condition assessment data

    Abstract Comprehensive condition assessment of wastewater force mains provides significant challenges to owners/operators of collection systems as the ability to shut down or expose the pipeline for a thorough inspection is often impractical due to operational and/or financial considerations. Traditional gravity sewer inspection techniques (i.e. visual-based technologies) do not always ...

  • 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 ...
