MANILA, Philippines — The Metropolitan Waterworks and Sewerage System Regulatory Office (MWSS-RO) is seeking to reduce Maynilad Water Services Inc.’s non-revenue water, or lost and unbilled water, in Metro Manila to below 30 percent next year.

In an online interview, MWSS-RO chief regulator Patrick Lester Ty said that the water utility firms’ non-revenue water currently stands at 34 percent, describing it as “high.”

“We have a plan right now for them to drastically reduce their non-revenue water,” Ty said.

“Basically, how I help them is, well I push them, with a ‘carrot and a stick,’” he added, but did not elaborate.

In contrast, he said that Manila Water’s non-revenue water is currently around 13 percent, closer to industry benchmarks for urban water utilities.

Maynilad is the concessionaire for the west zone of the National Capital Region.

The firm, controlled by Metro Pacific Investments Corp. and DMCI Holdings, covers parts of Manila, Quezon City (west of San Juan River), Caloocan, Malabon, Navotas, Valenzuela, Parañaque, Las Piñas and Muntinlupa, as well as parts of the province of Cavite.

Earlier in October, Maynilad said it is set to complete the ongoing replacement of two kilometers of old pipelines along Quirino Avenue in Parañaque by the third quarter of 2026.

The P215-million project, which it began in December 2024, aims to improve water distribution efficiency and support its non-revenue water reduction program.
