Water Utility Asset Management

Performance Analysis of the Asset Management System Pilot Deployment Project

The results of applying the asset management system logic to seven facilities, including Seoul Metropolitan Area Stages I–IV, showed a high degree of similarity to K-water’s renewal and replacement plans.

Category Pilot Deployment Results Renewal and Replacement Plan (‘21~’23) Number of Mismatched Assets Match Rate (%) Remarks
Total 4,562 801 3,761 17.6%
배경 Main Modules(M1~M30) 489 469 20 95.9%
Other Modules(M31) 4,073 332 3,741 8.2%
Analysis of Other Modules

Of 4,073 cases, 332 assets in poor condition were replaced based on operator judgment, while 3,741 assets that had reached the end of their service life but remained in good condition continue to be used.

Category Assets Subject to Replacement in the Past Three Years Facility Names
K-AMS 4,073 Camera, Automatic Fire Detection Equipment, Distribution Board, Field Control Panel, Optical Transmission Equipment, Battery Panel, Ground Terminal Panel, Chemical Storage Tank, Monitor, Modem, Indoor Lighting, Handrail, Rectifier, Cable, etc.
Replacement Plan 332 Automatic Fire Detection Equipment, Field Control Panel, Battery Panel, Indoor Lighting, Handrail, Rectifier, Cable, etc.

Analysis of 20 assets with mismatches between renewal/replacement results and plans from 2021 to 2023 showed that most were due to reasons such as idle facilities or reflection in higher-level plans, while some are scheduled for replacement after 2026.

Asset Management System Expansion Plan

  1. 1(Phase 1, through 2027) Enterprise-wide expansion of the asset management system (targeting 43 facilities where the system has not yet been established)
  2. 2(Phase 2, through 2029) Stabilization of the asset management system and advancement of logic, if necessary
  3. 3(Phase 3, from 2030) Full-scale operation of the asset management system
  1. Phase 1 (2025~2027)
    (DB Establishment Stage)
    • Pilot Sites (7 Sites)
      (K-water) Pilot Operation of the Asset Management System
      • Accumulation of Diagnostic Data by Asset
      • Accumulation of Repair and Maintenance History and Cost Data by Failure Type
    • Expanded Sites (43 Sites)
      (Outsourced Service) Collection of Basic Data and Preparation of DB
      • Collection and Analysis of Related Data and DB Establishment
      • Field Survey of Owned Assets
      • Investigation of Diagnostic History and Results for the Past 10 Years
  2. Phase 2 (2025~2029)
    (System Stabilization and Logic Advancement)
    • (K-water) Stabilization of the K-AMS system
      • Accumulation of diagnostic data by asset
      • Accumulation of repair and maintenance history and cost data by failure type
    • (Outsourced Service) Advancement of asset management system logic, etc., if necessary
      • Analysis of issues identified during K-AMS pilot operation
      • Supplementation of logic at each stage, including impact factors, evaluation criteria, and logic weights.
