Water and wastewater infrastructure are a somewhat invisible, yet critical, part of modern life. Incredibly, many buried assets have been in service for 50-100 years and are still in good condition. Conversely, other systems fail well before their predicted design lives, causing property damage, injury, and even loss of life. In many cases, early detection could have prevented catastrophic failure, and understanding the state of underground infrastructure has become a key priority for many municipalities. Industry has responded with a number of new and innovative technologies for condition assessment, however, understanding these tools can be difficult, as many vendors treat their proprietary systems as trade secrets.


Water and Wastewater Pipeline Assessment Technologies: Classification Systems, Sensors, and Results Interpretation provides a thorough guide to the technical workings of some of the most popular water and wastewater assessment technologies available, including CCTV crawlers, acoustic listening devices, laser sensors, 360˚ video cameras, pipe penetrating radar, and more.



  • Presents an overview of current technologies in CCTV inspection, including next generation video formats, high-definition resolution, and fisheye/sidescan technology.
  • Provides helpful tips and tricks to cut through technical jargon and identify the technological specifications to compare between multiple vendors.
  • Examines the pros and cons of competing technologies including laser and lidar, and provides an overview of unique approaches such as Pipe Penetrating Radar, Focused Electrode Leak Location, and more.
  • Highlights the importance of coding standards, data management, and software tools that can be leveraged to create a successful asset management program.


Water and Wastewater Pipeline Assessment Technologies: Classification Systems, Sensors, and Results Interpretation provides a mixture of theory and real-world, practical considerations ranging from deployment tips and data exchange formats to the technical limitations of different technologies. The book is a valuable resource for municipal employees, project engineers, and others involved in designing and implementing major inspection programs.
