Non Revenue Water is The Difference Between Volume of System Input and Billed Authorized Consumption August 15

August 15 - Malaysian Context - Why High NRW Levels? Not Difficult - Boring Subject (Never Mind Attitude) No Complains – Consumers Have Sufficient Supply No Incentives and Recognition Money Spend Not for the Root of the Problem (Rehabilitation Projects Only) Insufficient Allocation Unsustainable and non Committal (No Follow Through After Project) Ineffective Monitoring System False NRW Calculations and Data Interpretations Non Committal on Commercial Losses MOST IMPORTANT : Repetitions on Wrong Doings During New Water Supply Project Implementations and Substandard Materials and Poor Quality Workmanship

Key Conditions for Sustainable NRW Program Key Conditions for Sustainable NRW Program Pressure to develop NRW reduction strategy to show effectiveness in managing water loss management. Commitment from key decision maker within utility. Adequate technical understanding Organization and Information System (requires long term NRW strategy to reach an economic level and constantly monitored to maintained the level) August 15

August 15 KEY BENEFITS OF NRW PROGRAM Improving management of water supply distribution system Improving Customer Services & Revenue Collection Improving asset management system for maintaining, operating and upgrading the network components Reduce Operational Cost & Unscheduled Interruption Implementation of Water Audit Development of long term pipe replacement programme Deferment in Capital Expenditure

RESERVOIR OVERFLOW Contributes a significant % to overall NRW due to: –Over pumping (pumping fed reservoirs) –Faulty altitude / float valves (gravity fed reservoirs)

Overcome By: 1.Control of pumping operations 2.Maintenance of altitude valves or float valves (but scheduled valve maintenance inefficient and ineffective i.e.. too early or too late.) 3.Reliable and cost effective monitoring system with minimal maintenance Battery powered devices GPRS & SMS communication Web-based monitoring with SMS alert
