West Zone concessionaire Maynilad Water Services Inc. is nearing completion of several major water and wastewater infrastructure upgrades aimed at strengthening system reliability and environmental protection across Metro Manila and Cavite.

The projects are part of the company’s ongoing capital investment program focused on improving water security, wastewater services, and network efficiency in its concession area.

Why it matters

The upgrades are expected to boost treatment capacity, improve water distribution, and support environmental rehabilitation efforts—particularly for Manila Bay.

The improvements also reinforce operational resilience in densely populated urban communities where demand for water and sanitation services continues to grow.

Wastewater facility

Among the projects nearing completion is the upgrade of the 205-million-liter-per-day CAMANA Water Reclamation Facility in Dagat-Dagatan.

The plant serves the cities of Caloocan, Malabon, and Navotas and is Maynilad’s largest wastewater treatment facility.

Once fully upgraded, the facility will expand wastewater treatment capacity in these areas while supporting broader efforts to improve water quality and rehabilitate Manila Bay.

Water treatment plant

Maynilad is also completing upgrades at the La Mesa Treatment Plant 2 (LMTP2), a key component of the company’s water supply network.

The modernization of LMTP2 is expected to enhance operational reliability and strengthen the system’s ability to deliver a stable water supply across the West Zone.

Pipeline expansion

Complementing the facility upgrades is the ongoing completion of segments of the primary distribution pipeline along Daang Hari in Las Piñas City.

The pipeline forms part of the distribution system connected to the Poblacion Water Treatment Plant in Muntinlupa.

Once integrated into the network, the additional pipeline segments will improve water distribution and pressure management in southern parts of the concession area.

What they’re saying

“These projects reflect our focus on disciplined execution and system readiness,” said Maynilad President and CEO Ramoncito S. Fernandez.

“By upgrading critical facilities and strengthening our primary distribution network, we are reinforcing the reliability and resilience of our water and wastewater systems.” — Ed: Corrie S. Narisma
