MANILA — Water concessionaire Maynilad said it has yet to report any water interruption despite a decline in the water level of Angat Dam, its primary source of water supply.
Maynilad President and Chief Executive Officer Ramoncito Fernandez said the west zone of Metro Manila, where they are operating, continues to receive a sufficient supply of water even if the Angat Dam water level is down to around 155.43 meters as of August 3, 2026.

The critical level of Angat is 160 meters, while the minimum operating level is 180 meters.
Fernandez attributed the uninterrupted water supply to improvements by Maynilad, including the building of more water treatment plants and the reduction of leaks or non-water revenues (NRW).
“Tightening the network, improving our water sources outside of Angat, we have reduced the dependency,” said Fernandez.
Because of new water treatment plants and other facilities, Maynilad has reduced its dependency on Angat from 90 percent a few years ago to 83 percent today, and it targets to hit 81 percent by the end of the year.
NRW hit a record low of 29.7 percent, and they hope to further bring it down to 27 percent by the end of the year. Reducing NRW is a priority because water leaks are affecting the business, and water should reach more people and not go to waste because of leaks.
“Replacement of pipes, both primary and secondary, pressure-reducing valves to give us more flexibility in reducing pressure or keeps pressure in the areas, massive meter replacement,” said Christopher Lichauco, Maynila Chief Operating Officer.
