2 CNRW s Table of Organization Central NRW Management Planning and Support CNRW Analysis NRW Operations Integrated Meter Management Leak Detection Management Engineering and Construction

3 Program preparation and prioritization Budget allocation Project Management Monitoring of project deliverables Planning Projects Support Group Engineering and Construction Analysis Operations Leak Detection Management Design and monitoring of NRW reduction performance indicators Analysis of NRW reduction strategies Implementation of NRW reduction strategies DMA establishment, diagnostic and sustenance Monitoring of NRW reduction projects Integrated Meter Management

4 Planning and Support Program Planning Project Management Support Services NRW Management strategy, plans and programs Program prioritization Business plan preparation, updating and monitoring Benefits realization checking and monitoring Responsible for project delivery from planning to turn-over Works cross-functionally with other divisions Budget management (CAPEX and OPEX) Materials Management Billing preparation Administrative support Process management and documentation

5 What to consider primarily in project prioritization? Current stage of your organization s NRW management program DMA Establishment DMA Management DMA Sustenance

6 Stages of NRW Management DMA Establishment DMA Management DMA Sustenance Installation of flow and pressure monitoring points MEASURE Insertion of boundary valves Pipe laying Diagnostics Pressure management MANAGE Active leakage control Pipe rehabilitation Massive meter replacement Flow and pressure monitoring Periodic meter replacement Active leakage control MAINTAIN Flow and pressure monitoring AUTOMATION

7 Projects at different stages of NRW Management DMA Establishment What to consider?* Installation of flow and pressure monitoring points Insertion of boundary valves Pipe laying Nearest from the source Adjacent DMAs Natural boundaries (bodies of water, subdivisions, etc.) *If with limited resources, prioritization is needed.

8 Projects at different stages of NRW Management DMA Management What to consider? Diagnostics Pressure management Active leakage control Pipe rehabilitation Massive meter replacement Flow and pressure monitoring Nearest from the source Adjacent DMAs Potential recovery considering cost of water

9 Projects at different stages of NRW Management DMA Sustenance What to consider? Periodic meter replacement Active leakage control Flow and pressure monitoring Replacement cycle of water meters

10 Selection Criteria for Pipe Rehabilitation Recovery Pipe Condition Maintenance Cost Water Quality Hydraulic system and pressure managements status NRW Volume COST OF WATER Age of pipe Depth of pipe Burst frequency or leak occurence Pipe material; ACP, GIP, FRP, Substandard PVC Encroached within property/alignment Multiple layer of pavement Water Quality Hydraulic System Status (Pressure management status, NRW condition of adjacent DMAs, Primary Audit)

11 DMA Level (Sample Case : HS Hobart) 06-COM03G 06-COM02I Hydraulic system is not pressure managed High primary losses DMA 06-COM02I 06-COM03G Total Before After Variance HS Hobart Before After Variance 0.08 Primary Losses Before 6.27 After 9.98 Variance 3.71

12 HS Level (Sample Case : HS D. Tuazon Gravity) 14-RSV02I 19-RSV01A Hydraulic system is 100% pressure managed Cleared from primary losses DMA Before 14-RSV02I RSV1A 2.33 Total 4.75 After Variance HS D. Tuazon Gravity Before 14.7 After 6.66 Variance -8.04

13 Selection Criteria for Pipe Rehabilitation Recovery Pipe Condition Maintenance Cost Water Quality Hydraulic system and pressure managements status NRW Volume COST OF WATER Age of pipe Depth of pipe Burst frequency or leak occurence Pipe material; ACP, GIP, FRP, Substandard PVC Encroached within property/alignment Multiple layer of pavement Water Quality Hydraulic System Status (Pressure management status, NRW condition of adjacent DMAs, Primary Audit)

14 What projects to prioritize? Service Level (24hrs/16psi) Regulatory Compliance (ACP and GIP) Recovery Alignment with Government Projects Expansion

15 In summary Apart from the established parameters in project selection, project prioritization depends on your organization s: current stage in NRW management program (DMA Establishment, Management or Sustenance) business needs
