Scenario-Based Water Purification Plant LCC Analysis for Strategic Asset Management

Abstract

Recently, strategic asset management (SAM) for water infrastructure has emerged in Korea and abroad. Strategic asset management requires measures to predict the costs that may occur during a facility's life cycle, addressing them with minimal maintenance costs through timely budget injections. In this study, life cycle cost (LCC) analysis was performed by setting up scenarios for maintenance costs and analysis period changes that may occur during a facility's life cycle by dividing water purification facilities into 13 sections and 42 divisions. As a result of the application of the scenario, the maintenance costs incurred by the filtering facility were maximized. In addition, as the initial repair time for each water treatment facility was advanced, maintenance costs increased from a section perspective, but items decreased from a detailed perspective. Therefore, it is deemed necessary to adjust the appropriate timing of repair and replacement processes to develop strategic asset management measures in the future.
