Title:"Analysis of the Total Cost of Large Diameter Pipe Failures" - Supplemental Report
Date:8/8/2007
Introduction:
An earlier Foundation study (Costs of Infrastructure Failure, 2002) had reviewed the types of costs associated with infrastructure failure, and had developed tools to support the tracking of such costs, but the study did not include cost analyses of actual failures. A compilation and analysis of the costs associated with 30 relatively recent large diameter pipe failures (20-inch diameter and up) across North America are presented in this supplemental report.
When deciding whether or not to proactively inspect and rehabilitate or replace an existing pipe, a key consideration is the total "reactive" cost in the aftermath of a failure. Large diameter pipes can fail catastrophically, resulting in considerable flooding, damage and possibly major disruptions to normal business and traffic patterns in urban areas. There are limited sources of centralized information of the total costs of large diameter pipe failures.
