Underground Utility Locating Technologies for Condition Assessment and Renewal Engineering of Water Pipeline Infrastructure Systems

Abstract

AbstractUnderground asset locating practices use new and existing technologies to accurately identify, characterize, and map buried utilities through the integration of professional utility records, visual site inspection, geophysical techniques, survey, and utility exposure. The efficient use of locating practices allows effective condition assessment and renewal engineering applications, which, in turn, improves asset management practices for water utilities. Utility engineers, managers, and practitioners need to be familiar with all locating technologies (working principles, capabilities, and limitations) to have an effective selection of the appropriate technologies for every scenario. There are capabilities and limitations of all existing underground utility locating technologies that are used by water utilities. This paper provides the factors affecting the reliability of underground pipe locating surveys and presents an overview of the capabilities and limitations of the locating technologies to gu...
