Desktop Analysis for Proactive Capital Investment Planning of Aging Pipeline
Publication: Pipelines 2023
ABSTRACT
Failure of buried pipelines can result in costly renewal and replacements (R&R), significant disruption of service, and may have substantial environmental consequences. Identifying failure-prone pipes for R&R can help avoid pipe failure. Desktop analysis of a pipe network along with analysis of the physical and geomorphologic characteristics of a service area is the first cost-effective step to develop a proactive plan for maintaining good service practice under various expenditure scenarios. This study presents GIS-based desktop analysis for sewer mains for the development of risk-based capital investment plan and project prioritization using KANEW model. The risk analysis was conducted, and pipes were ranked under five risk classes based on the likelihood of failure in terms of pipe age, useful life, material, failure pattern, soil condition, and consequence of failure in terms of social, economic, and environmental impacts to the system and service area. The cost of R&R from each risk class is also determined for project prioritization.
