West Zone concessionaire Maynilad Water Services, Inc. (Maynilad) invested approximately Php4.79 billion in 2024 to replace 142 kilometers of aging and leaky pipelines across its concession area—part of the company’s sustained efforts to improve water service reliability and reduce system losses.
The pipe replacement works were implemented in key areas including Muntinlupa, Las Piñas, Parañaque, Pasay, Makati, Quezon City, and Caloocan. These involved the replacement of pipelines primarily installed between 1986 and 2008, with diameters ranging from 50mm to 700mm.
Through these 2024 projects, Maynilad recovered around 37 million liters per day (MLD) of potable water—enough to meet the daily needs of over 230,000 customers.
“Rehabilitating our inherited pipeline network is central to our long-term water security strategy. By proactively upgrading old infrastructure, we are able to reduce losses, optimize supply, and deliver more consistent service to our customers,” said Maynilad President and CEO Ramoncito S. Fernandez.
Since its re-privatization in 2007, Maynilad has already replaced 3,264 kilometers of old pipelines—a distance roughly equivalent to the stretch between the Philippines and Japan. This accounts for approximately 70% of the total distribution network it inherited from the government, which included pipe segments dating back to the colonial era.
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.
