Indirect condition assessment of water mains

Abstract

The presented paper summarizes a basic theory of indirect condition assessment including a definition of condition assessment, factors contributing to deterioration and possible outputs of the condition assessment. Furthermore, the legal requirements concerning this issue specifically in the Czech Republic and the Slovak Republic are listed. As a part of the intended complex methodology for condition assessment of water distribution systems (WDS), a methodology for condition assessment of water mains was developed. The methodology is based on condition indicators (CI) and multi-objective optimization. The paper presents the proposed methodology and its application in two case studies. The proposed methodology achieved good results and it showed certain significant benefits – e.g. satisfactory level of detail, optional user modification.The presented paper summarizes a basic theory of indirect condition assessment including a definition of condition assessment, factors contributing to deterioration and possible outputs of the condition assessment.
