Recovered volume enough to supply daily needs of over 1.6 million people.
West Zone concessionaire Maynilad Water Services, Inc. (Maynilad) made significant headway in reducing water losses in 2025, closing the year with a Non-Revenue Water (NRW) level of 30.7%, down from 38.4% in December 2024.
This 7.7 percentage-point reduction translates to 256 million liters per day (MLD) of recovered water—roughly equivalent to the output of a water treatment plant and enough to meet the daily needs of more than 1.6 million people. On a full-year basis, Maynilad achieved a YTD average NRW of 34.9%, a five percentage-point improvement from 2024, signaling sustained momentum toward its long-term targets.
“This progress reflects the collective effort of our teams and the effectiveness of our multi-pronged approach to NRW reduction. Every liter of water recovered improves system efficiency by reducing the need to overproduce treated water, allowing us to optimize treatment, pumping, and distribution using existing assets, while strengthening our ability to provide reliable service while stewarding resources responsibly,” said Maynilad Chief Operating Officer Christopher J. Lichauco.
Throughout 2025, Maynilad scaled up operational interventions to accelerate leak detection, leak repair, meter replacement, and pipeline rehabilitation. The company repaired over 70,000 small leaks—a 22% increase from the previous year—alongside 206 large pipe leaks in primary distribution systems and 82 kilometers of old pipelines replaced in high-loss areas.
Maynilad also leveraged technology-enabled solutions to boost field productivity, including AI-assisted leak localization through tools like Infrawise and the pilot deployment of GAILL (Geo-AI Leak Locator).
“These innovations helped optimize our field activities and allowed us to detect and resolve leaks faster—especially in areas where traditional methods are less effective,” said Central NRW Head Engr. Ryan B. Jamora.
Maynilad’s NRW reduction program remains a cornerstone of its broader service reliability strategy, with ongoing efforts geared toward achieving its 2027 target of 25% NRW, as committed in its business plan for the 2023–2027 rate rebasing period.
