  • 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 ...

  • 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 ...

  • 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 ...

Her green eyes now bulge under heavy lids on a gaunt ...


  • Denver Colorado - Harvard Gultch Interceptor - Case Study

    Summary Pipe penetrating radar (PPR), a new pipe inspection technology was used for condition assessment in a 27 inch interceptor in Denver, CO. Metro Wastewater Reclamation District (MWRD), the owner of the interceptor had limited information about the condition of the pipe, so they contacted SewerVUE in order to undertake a multisensory pipe condition assessment that included CCTV, PPR ...
