4 KEY NATIONAL STATISTICS (WATER) - 2010 Raw Water Source : Mainly Surface Water with minor groundwaterDesign Capacity : 16,771 MLDProduction Capacity : 14,065 MLDTotal No. of Treatment plant : 458Total Length of Pipes : 131,286 KMPipe Material : AC (31.9%), PE (16.8%), MS (24.7%), uPVC (15.5%), DI (7.4%), CI (1.2%), Others (2.5%)Total Connection :6,459,663Connections : Domestic (86.7%), Non Domestic (13.3%)Per capita Consumption : 225 litre/cap/dNRW : 36%Population Served : Overall (94.2%)Urban (96.8%), Rural (89.7%)
5 FACTS ABOUT WATEROver 1.5 billion people do not have access to clean, safe water.Almost 4 million people die each year from water related diseases.43% of water related deaths are due to diarrhea.98% of water related deaths occur in the developing world.Unsafe water is the biggest killer of children under five; around 90% of all diarrheal deaths are in this age group.Lack of access to clean water and sanitation has claimed more lives through disease than any war through guns.

7 THE WATER CYCLE Total Water Recycle And how will success affect the stakeholders?And here is where we would outline the key benefits to each unique stakeholder – like in the MAS BTPWater Cycle - Nature Water Cycle - Built Water CycleTotal Water Recycle
8 OBJECTIVE OF STUDYTo determine whether the planning, implementation, and monitoring drinking water quality has been managed properly, efficiently and effectively in accordance with the standards to ensure that drinking water supplied is safe and acceptable to consumers.
9 THE SCOPE OF THE AUDITAn audit covers 3 years from 2005 to 2007 to carry out analysis of data. Whereas in 2008, it will lead to an audit inspection on site. Involve the cooperation of:State Water Operator - Covered the whole countryMOH (Ministry of Health Malaysia)SPAN (National Water Services Commission) for the states in Peninsular only and Regulatory Bodies of Water (Sabah & Sarawak).Covers the whole course starting from the raw water source to the user.The study was carried out on networks / course for the 42 /453 of the treatment plant from the treatment plant in the country selected as a sample for an audit of drinking water quality management studies.
10 METHODOLOGY Audit methodology is included: Samples were collected by the MOH and the State Water Supply Agency.Inspection of the sampling stations.Carry out analysis of data.Ensure procedures are in compliance with standard sampling.Carry out comparison of the sampling schedule, the performance of water quality and water quality trends for each state.Implement the questionnaire concerning the quality of water supplied to consumers.Comparison of unit cost and quality of water supplied.

16 Ageing Infrastructure AUDIT FINDINGS……Ageing Infrastructure1. Treatment PlantUsing Conventional Treatment Vs Detoriate Raw Water QualityLaboratory Equipment – Unreliable Data64% of Fluoride Dosing System not Functional2. Distribution System- Main Pipeline & Reticulation System- Burst & Leaks – Turbid Water,- Corroded Pipe –Rusty Coloured Water- Sampling Stations- Site Testing – In-situ Test – equipment not well maintain- Weekly/ Monthly Testing – Unreliable Data- cased by – wrong sampling procedure- sample not send on time3. Plumbing System- G.I Communications Pipe - Corroded- Old Storage Tank – Corroded – (press steel tank) – resulting in colored waterNot calibratedOld equipment
17 Operation & Maintenance AUDIT FINDINGS……Operation & MaintenanceReservoirUnscheduled Cleaning – Sediment Built UpColoured & Odour Water2.
