West Zone concessionaire Maynilad Water Services, Inc. (Maynilad) now delivers piped-in water to around 10.5 million people as of the first quarter of 2025, marking continued gains in service coverage, availability, and water pressure across its concession area.

As of March 2025, the company had 1,556,603 active water service connections, covering 94.7 percent of the West Zone. This is up from 77.8 percent coverage in 2006, when Maynilad came under new management.

Water service availability and pressure have also improved significantly. Around 96.8 percent of customers now receive 24-hour water supply, compared to 32 percent in 2006. Likewise, 96.8 percent of customers get water at an average pressure of at least seven pounds per square inch (psi)—the minimum required to push water up to the second floor of a structure—up from 45 percent in 2006.

Since its re-privatization in 2007, Maynilad has replaced 3,293 kilometers of aging pipelines—equivalent to approximately 72 percent of its inherited pipe network—to help minimize losses and improve network reliability.

“We remain focused on expanding access and sustaining service levels as demand rises,” said Maynilad President and CEO Ramoncito S. Fernandez. “It’s a long-term commitment that supports both water security and the well-being of the communities we serve.”

Maynilad is the largest private water concessionaire in the Philippines in terms of customer base. It is the concessionaire of the Metropolitan Waterworks and Sewerage System (MWSS) for the West Zone of the Greater Manila Area, which is composed of the cities of Manila (certain portions), Quezon City (certain portions), Makati (west of South Super Highway), Caloocan, Pasay, Parañaque, Las Piñas, Muntinlupa, Valenzuela, Navotas and Malabon all in Metro Manila; the cities of Cavite, Bacoor and Imus, and the municipalities of Kawit, Noveleta and Rosario, all in Cavite Province.
