I. Background
H.E. Ek Sonn Chan 1993-2012

1895-First Water Work in Cambodia-Production : 12,000 M3/day-Distribution: 30km of Cast Iron

1993-2000 (Turnaround through Reform)-Rehabilitation Stage-Structural change/HR Frame/Culture Frame-Autonomous/Full costs recovery

1975-1979-Almost no operation-High degradation of facilities

From 2000-2012 (Expansion)-Service extension-Social responsiveness-Quality of services

1980-1993-Resume operation-Heavy government subsidy-Very poor services

From 2012-2021 (Fine-Tune)-Continue extension-Innovation the process-Pursue ISO Certificate

From 2021-Present (Turnaraound)-Continue Extension as Mater Plan 2021
-Innovation the Management Process-Improve HRM/HRD-Apply Smart Water Management System
