Abstract

This study provides a methodology that can be utilised for identifying pipe sections, which can be considered under high risk of failure. Application of the proposed methodology is demonstrated using a case study involving an in-service large (~1.7 km) critical water main in Sydney, Australia. Geospatial features from Google Earth Pro TM and Google Street View TM were used to assess and quantify typical urban environmental attributes, which can be used for identifying pipe failure hotspot locations. Failure history was used to verify the basis of the methodology developed. It was demonstrated that a sound assessment of the pipe conditions is possible through inexpensive geospatial feature analysis. This development can greatly enhance and reduce costs associated with current pipe condition assessment processes.
