Pangilinan-led Maynilad Water Services, Inc. reported a sharp reduction in water losses last year that directly increased water supply for customers and strengthened system efficiency.

In a stock exchange report on Monday, the west zone concessionaire said it ended the year with a non-revenue water (NRW) level of 30.7 percent, down from 38.4 percent in December 2024. 

Maynilad said the 7.7 percentage-point drop translated to 256 million liters per day of recovered water—enough to meet the daily needs of more than 1.6 million people. 

For the full year, Maynilad posted an average NRW of 34.9 percent, a five percentage-point improvement from 2024.

“This progress reflects the collective effort of our teams and the effectiveness of our multi-pronged approach to NRW reduction,” Maynilad Chief Operating Officer Christopher J. Lichauco said.

“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,” he added.

Maynilad said the loss reduction was supported by the repair of over 70,000 small leaks, the fixing of 206 large pipe leaks, and the replacement of 82 kilometers of old pipelines in high-loss areas in 2025.

“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, referring to artificial intelligence-assisted leak detection tools such as Infrawise and GAILL.

Maynilad said the program supports its push to cut NRW to 25 percent by 2027 under its 2023 to 2027 rate rebasing plan.
