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 ...

A new vision on the condition of city of Toronto’s sewer networks
Situation And Objectives After the amalgamation of Toronto in 1998, Toronto Water – the department in charge of managing the combined infrastructure systems – was mandated to consolidate all underground facilities data and centralize sewer inspection processes on behalf of the newly merged city. Ten years later, a great deal of work in this regard remained undone. It was a monumental ...

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 the ...

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 ...

The world watches as evides manages steel main with innovative technology, and outstanding results follow
It was a perfect day for an inspection. Under a crisp blue sky, in the polders along a major motorway near Rotterdam, more than 40 water professionals from The Netherlands, Australia and the UK gathered to witness a unique project undertaken by the water utility Evides Watercompany. The purpose of the project was to showcase the 24-sensor PipeDiver®, an innovative tool from Pure Technologies ...

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 be ...

It Began With A Little Red Wagon: Collecting Real Information To Make Critical Decisions
Tarrant Regional Water District (TRWD) and Pure Technologies U.S. (Pure) have a long history of working together to keep the water transmission mains in the Dallas-Fort Worth (DFW) area in good operating condition. The partnership began 17 years ago with mutual development of electromagnetic technology to inspect prestressed concrete cylinder pipe (PCCP). One of Pure’s first ...
