Maynilad Water Services Inc. reduced its non-revenue water (NRW) level to 30.7 percent in 2025 from 38.4 percent in December 2024, the west zone concessionaire said Monday.
The 7.7 percentage-point decline resulted in the recovery of 256 million liters of water per day. The utility firm said the recovered volume is roughly equivalent to the output of a single water treatment plant and is enough to supply more than 1.6 million people daily.
On a full-year basis, Maynilad recorded a year-to-date average NRW of 34.9 percent. This represents a 5 percentage-point improvement from 2024 as the company moves toward a long-term target of 25 percent NRW by 2027.
Maynilad chief operating officer Christopher Lichauco said the progress reflects the effectiveness of a multi-pronged approach to reducing water losses.
“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,” Lichauco said in a statement to the Philippine Stock Exchange.
The company achieved the reduction by accelerating leak detection, meter replacement and pipeline rehabilitation.
Maynilad repaired over 70,000 small leaks in 2025, a 22-percent increase from 2024, while addressing 206 large pipe leaks and replacing 82 kilometers of old pipelines.
To boost field productivity, the utility deployed AI-assisted localization tools such as Infrawise and GAILL, or 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 Maynilad Central NRW head Ryan Jamora.
Maynilad said its NRW reduction program remains central to its service reliability strategy, with ongoing efforts aimed at meeting its 2027 target of 25 percent NRW under its business plan for the 2023–2027 rate rebasing period.
