NRW Reduction - THEN District Metering Area Mainline Renewal Leak Detection Pressure Management Leak Repair Service Connection Rehab Meter Maintenance Pilferage Addressing Non Revenue Water Physical Losses
NRW Challenges • Unbilled Authorized Consumption • Government entities can withdraw water in any fire hydrant. • UAC computation is based on assumptions. • Commercial Losses • No institutionalize system for pilferage evaluation and prevention • Physical Losses • DMA results are not accurate • Only 1 leak detection team • Not all assets are reflected in the • Leak detection is based on DMA results and GIS map sweeping scheme • No system for monitoring the • Distribution scheme is empirical • Quarterly pressure monitoring condition of pipelines • No criteria for renewal of mainlines Non Revenue Water

2 O 2 NRW Action Plan Pressure Management - Installation of PRVs on strategic areas. - Procurement and installation of pressure loggers on strategic points - Distribution Scheme shall be based on hydraulic model. - SCADA Addressing Non Revenue Water Physical Losses
2 O 2 NRW Action Plan Hydrant Withdrawal - All LGU’s are only allowed to withdraw water on its designated fire hydrants unless force majeure. - Such hydrants will be metered and monitored. - Withdrawal from other hydrants (not designated) will be considered illegal. Addressing Unbilled Authorized Non Revenue Water Consumption
2 O 2 NRW Action Plan Meter Maintenance - Conduct Random Field Meter Testing on 5% of the total SCs. - Evaluate large meter size’s consumption rate and replace with appropriate meter size. Addressing Non Revenue Water Commercial Losses
2 O 2 NRW Action Plan • Unbilled Authorized Consumption • Metered Withdrawal on fire hydrants only on designated areas per LGU • Commercial Losses • Random Field Meter Testing on 5% of total no. of SCs • Large Meter Sizing program • Physical Losses • Institutionalization of hydraulic • Procurement of Advance LD equipments • Construction of Leak Detection facility areas • Asset Inventory • Mesh System on Leak Detection • Asset condition monitoring • Procurement and Installation of PRVs • Mainline Renewal • Real Time pressure monitoring • Hydraulic model Non Revenue Water
