As a result of these strategic investments, Clark Water consistently delivers 100% coverage for water and wastewater services, continuous service, full regulatory compliance, and industry-leading performance—solidifying its position as a benchmark in the Philippine water utility sector.
Clark Water upholds operational excellence through four strategic pillars: Efficiency, Environmental Protection, Customer Value, and People & Community. These guide its mission to deliver sustainable, high-quality water services in the Clark Freeport Zone.
Clark Water ensures competitive rates, 24/7 service, and full compliance with Philippine National Standards for Drinking Water. The Company maintains world-class Non-Revenue Water (NRW) levels at just 6%, supported by a 20% supply buffer for reliability. It has achieved 100% sewer network integration and operates a centralized, compliant wastewater treatment facility, meeting DENR standards (DAO 2016-08 & DAO 2021-19).
These achievements come amid growing demand, with locators increasing from 1,096 in 2021 to 1,213 in 2025, and total water service connections reaching 1,894.
“Hindi pwedeng walang tubig, and we have lots of restaurants and hotels. We cannot afford to have water that is below standard. These are the challenges to Clark Water, and I am very proud to say that they have kept their commitment, their promise, and their performance,” shared Devanadera.
Beyond its core operations, Clark Water champions a safe and inclusive workplace while promoting the well-being of employees and communities through responsible water resource management. The Company also extends its impact beyond the Freeport Zone by supporting water access initiatives in Pampanga, building vital water supply facilities, and installing refrigerated drinking fountains to encourage hydration and public health.
Clark Water continues to recognize the importance of continued investment in its facilities as the CFZ continues to thrive as one of the Philippines’ major tourism and investment hubs.
“Continuous investment in water and wastewater infrastructure is critical to sustaining the growth of the Clark Freeport Zone as one of the Philippines’ premier tourism and investment destinations. By upgrading our facilities and introducing innovative solutions, we ensure that locators and communities have access to reliable, high-quality, and sustainable services. These improvements not only support economic development but also reinforce our commitment to environmental stewardship and long-term resilience,” said Lyn Zamora, General Manager of Clark Water.
Since Manila Water assumed operations in 2011, Clark Water has invested approximately P6.6-billion to upgrade water and wastewater systems across the Freeport Zone.
Clark Water has created the 2026 Service Improvement Plan, a strategic project centered on four major areas, as part of its long-term vision. Diversifying water sources is a top priority for water security in order to lessen dependency on groundwater and guarantee resilience and sustainability. In order to ensure safe and effective service delivery, service quality drives facility modifications to meet changing water and wastewater regulations.

“As we celebrate 25 years of service, we reaffirm our commitment to world-class water and wastewater solutions for the Clark Freeport Zone. This milestone is a promise for the future—where sustainability, innovation, and excellence remain at our core. With the investment, we will continue supporting growth while protecting our environment and communities.
