West zone concessionaire Maynilad Water Services Inc. said Thursday its non-revenue water (NRW) level fell to 36.2 percent as of the first quarter of 2025 from 66.4 percent before it was reprivatized in 2006.
Maynilad Central NRW head Ryan Jamora said the recent milestone translates into a recovery of 970 million liters per day (MLD), enough to supply the daily water needs of millions of residents across the west zone.
“Reducing water losses in a highly complex and aging network like ours demands long-term commitment and continuous innovation,” he said.
The achievement is the result of nearly two decades of sustained investments and system upgrades, he said.
Maynilad inherited one of the oldest and most leak-prone pipeline networks from the Metropolitan Waterworks and Sewerage System (MWSS).
Despite this challenge, the company managed to significantly curb water losses through a combination of technical solutions and large-scale capital expenditures.
Key components of Maynilad’s NRW management program include the establishment of district metered areas (DMAs), advanced network diagnostics, active leak detection and repair, large-scale pipe replacements and strict meter management.
The company said it replaced 3,293 kilometers of aging pipelines and repaired more than 18,000 leaks as of the first quarter of 2025.
According to its IPO prospectus, Maynilad plans to further reduce its NRW to 25 percent by 2027 and 20 percent by 2030, maintaining this level through the remainder of its concession.
