Pure Technologies PipeWalker™ Condition Assessment Platform

Overview Specifications Documentation & Tools


Product Features
  • Manned condition assessment tool for concrete water pipelines (PCCP, RCCP, BWP)
  • Accurately pinpoints areas of distress with electromagnetic and detailed visual assessment data
  • Offers quick and easy inspections using common and available access ports
  • Fully controlled during inspection to ensure data quality
  • Easily equipped with additional sensors to map and profile the pipeline


Pipe wall condition data collected by the PipeWalker™ platform allows utilities to make rehabilitation and management decisions on a pipe-by-pipe basis.

The PipeWalker platform is a lightweight, modular condition assessment tool operated in dewatered pipelines by a team of highly trained technicians. It is ideal for inspecting critical large-diameter water pipelines that can be removed from service to achieve maximum data quality. The tool can effectively identify and precisely locate:

  • Broken wire wraps in prestressed concrete cylinder pipe
  • Broken bar wraps and cylinder wall loss in bar-wrapped pipe   


PipeWalker is a reliable and effective tool that leverages two decades of inspection experience to simplify the collection of pipe wall data collection.

By combining high resolution condition data with visual inspection, asset owners can effectively prioritize resources and reduce unplanned operational costs while increasing confidence in their long-term management decisions.

During an inspection, highly trained technicians operate the PipeWalker platform in a dewatered pipeline, collecting electromagnetic data and completing a detailed visual inspection. This combination of high-resolution data and visual inspection provides utilities with the best understanding of pipe wall condition. An inspection with the PipeWalker platform accurately documents the condition of the pipe’s internal lining, joints, and connections while pinpointing signs of incipient failure.

This platform can inspect a wide range of pipeline diameters and can be quickly disassembled during inspection to pass in-line valves. The tool is easy to deploy and can be inserted and extracted through existing appurtenances, reducing the civil work required prior to its deployment. Data collected with the PipeWalker platform can be quickly analyzed to provide results, which allows the pipeline owner to complete repairs during the same pipeline shutdown.

With more than two decades of PipeWalker experience, Xylem has collected over 2,750 miles (4425 km) of data from pipeline inspections around the world.
