West Zone concessionaire Maynilad Water Services, Inc. (Maynilad) is expanding its total water storage capacity from 779 million liters in 2024 to 960 million liters by 2026, through the construction of three new reservoirs—two in Quezon City and one in Valenzuela.
These new facilities will enhance supply availability and help maintain stronger water pressure during peak demand periods, particularly in elevated areas where pressure tends to drop due to high withdrawal from low-lying communities.
This initiative is part of Maynilad’s ongoing program to expand water storage infrastructure in support of long-term supply reliability.
“By building more strategically located reservoirs, we are strengthening our distribution system and ensuring better service for customers, especially in areas that experience low pressure during peak demand,” said Maynilad President and CEO Ramoncito S. Fernandez.
Maynilad is pursuing this expansion through strategic cost management and process efficiency initiatives, including the use of renewable energy, to ensure that its infrastructure investments are both economically and environmentally sustainable.
The project forms part of Maynilad’s Php31.9-billion capital expenditure plan for operations support programs from 2025 to 2029.
As of June 30, 2025, Maynilad operates eight water treatment plants, 39 operational reservoirs, 41 pumping stations, and a 7,886-kilometer distribution network. It also maintains 21 serviceable deep wells that may be activated as backup during supply interruptions.
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.
