Abstract
Deterioration of water mains causes serious problems in major urban communities worldwide. This paper presents the findings of a recent study conducted on pipe-break data in an effort to identify and categorize the key factors that contribute to the deterioration of water mains and examine the applicability of existing deterioration models for water mains in representing actual field conditions. The data used in this paper were collected from a municipality that has a large water distribution network in Canada. The collected data cover pipe break records of of water mains. Unlike the common thought by practitioners, the performed analysis reveals that water mains of long lengths do not necessarily have more breaks compared to those of short lengths. The analysis performed using existing models shows that they provide poor representation and inadequate explanation for the deterioration of water mains. The research findings presented in this paper are expected to be useful to academics and practitioners (municipal engineers, consultants, and contractors) in analyzing deterioration trends of water mains.
