Leak Detection: Technology and Implementation

Ageing infrastructure and declining water resources are major concerns with a
growing global population. Controlling water loss has therefore become a priority for
water utilities around the world. In order to improve their efficiencies, water utilities
need to apply good practice in leak detection.

To deal with losses in an effective manner, particularly from networks in water-scarce
areas, water utility managers are increasingly turning to technology to reduce costs,
increase efficiency and improve reliability. Companies that continuously invest in
technology and innovation should see a positive return on investment in terms of
improving daily operations and collection and analysis of network data for decisionmaking
and forward planning.

Methodologies for achieving the best results to reduce water losses are continuously
evolving. Water utilities and equipment manufacturers are increasingly working
together to stretch the boundaries of current knowledge. This is leading to some
innovative technologies and new product development to complement current
methodologies. This book reflects the situation at the time of publication.

This second edition of the book updates practices and technologies that have been
introduced or further developed in recent years in leakage detection. It outlines recent
advancements in technology used, such as satellite aided methods in leak location,
pipeline inspection with thermal diagnostics, inspection of pipelines by air using infrared
or thermal imaging cameras, drones for leak detection activities and even sniffer
dogs. In addition, it is enriched with new case studies that provide useful examples of
practical applications of several leak detection practices and technologies.
