Clark Water has activated a comprehensive El Niño Mitigation Plan to guarantee a continuous water supply for the Clark Freeport Zone. The Manila Water subsidiary is executing this drought-response strategy by rehabilitating 10 existing wells and redrilling two abandoned deep wells. To further expand and diversify its available raw water sources, the utility is actively developing two new production wells and constructing treatment facilities that will support two additional deep wells.
A Multi-Pronged Approach to Water Security
The utility company is rehabilitating 10 existing wells and redrilling two abandoned deep wells to maximize groundwater extraction from existing sources . Beyond infrastructure and operational initiatives, Clark Water remains committed to environmental sustainability and watershed protection. These infrastructure upgrades are part of a broader, long-term commitment following Clark Water's 25-year service milestone, which is backed by a PHP 17.3 billion investment program running until 2040 .
The company has also intensified its aquifer and deepwell monitoring program through daily performance assessments of operating wells and monthly monitoring of Static Water Levels (SWL) and Pumping Water Levels (PWL) to support the sustainable management of groundwater resources . To further strengthen operational reliability, Clark Water maintains an ongoing replenishment program for critical spare parts and strictly implements preventive maintenance activities across its facilities and equipment.
Industry-Leading Performance and Environmental Commitment
Clark Water has achieved an industry-leading Non-Revenue Water (NRW) rate of only 6% during the first half of 2026, significantly lower than the national average . Key measures include proactive leak detection and rapid leak repair, optimized pressure and supply management, recalibration of tank rule curves, implementation of customer meter replacement programs, and the establishment of District Metered Areas (DMAs) to accurately identify and address high-NRW zones .
The utility has also partnered with the Clark Development Corporation to plant over 8,300 trees across 10 hectares since 2014 to protect vital water sources . Clark Water General Manager Lyn Zamora emphasized the importance of these efforts: "Water security remains one of Clark Water's highest priorities as we continue to support Clark's growth as one of the country's premier investment and economic hubs. Through proactive planning, strategic infrastructure investments, and responsible resource management, we are strengthening the resilience of our water supply system" .
