West Zone concessionaire Maynilad Water Services, Inc. (Maynilad) completed a ₱200-million pipe replacement project in Las Piñas City, upgrading more than 23 kilometers of aging pipelines to improve water pressure for around 50,000 customers.
The project involved the replacement of 23.11 kilometers of old, leaky, and undersized pipes ranging from 75mm to 300mm in diameter. These upgrades enabled the recovery of about 3.73 million liters per day (MLD) of water, supporting Maynilad’s ongoing efforts to reduce system water losses and improve overall network efficiency.
The upgrades have improved water pressure in the project areas, with pressure levels increasing from around 4 pounds per square inch (psi) to 16 psi. At this pressure, water can reach up to the third storey of a structure without the need for a booster pump, depending on the building’s elevation and internal plumbing conditions.
The project benefits customers in barangays Manuyo Dos, Talon Singko, Talon Uno, Talon Tres, and Pulang Lupa Dos.
Completed in 2025, the Las Piñas pipe replacement project forms part of Maynilad’s Non-Revenue Water (NRW) Management Program, which focuses on reducing water losses and improving system efficiency through the establishment of District Metered Areas (DMAs), advanced network diagnostics, active leak detection and repair, pipe replacement initiatives, and strict meter management.
“By replacing aging, leaky, and undersized pipelines, we are strengthening our distribution network to better accommodate growing demand while ensuring the continued delivery of safe, reliable, and sustainable water services,” said Maynilad President and CEO Ramoncito S. Fernandez. “These investments are essential to improving system efficiency and reducing water losses across our service area.”
Maynilad operates the largest water concession by population served within a single concession area in the Philippines. It is a 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.
