Leak Detection: Technology and Implementation

Angebote / Angebote:

Ageing infrastructure and declining water resources are major concerns with agrowing global population. Controlling water loss has therefore become a priority forwater utilities around the world. In order to improve their efficiencies, water utilitiesneed to apply good practice in leak detection.To deal with losses in an effective manner, particularly from networks in water-scarceareas, water utility managers are increasingly turning to technology to reduce costs, increase efficiency and improve reliability. Companies that continuously invest intechnology and innovation should see a positive return on investment in terms ofimproving daily operations and collection and analysis of network data for decisionmakingand forward planning.Methodologies for achieving the best results to reduce water losses are continuouslyevolving. Water utilities and equipment manufacturers are increasingly workingtogether to stretch the boundaries of current knowledge. This is leading to someinnovative technologies and new product development to complement currentmethodologies. This book reflects the situation at the time of publication.This second edition of the book updates practices and technologies that have beenintroduced or further developed in recent years in leakage detection. It outlines recentadvancements in technology used, such as satellite aided methods in leak location, pipeline inspection with thermal diagnostics, inspection of pipelines by air using infraredor thermal imaging cameras, drones for leak detection activities and even snifferdogs. In addition, it is enriched with new case studies that provide useful examples ofpractical applications of several leak detection practices and technologies.
