The Teresa plant, originally designed to source water from the Kaliwa Dam and to produce 300 million liters per day of potable water, has been put on hold, Maynilad said.

MANILA, Philippines — West Zone concessionaire Maynilad Water Services Inc. has shelved plans to build a P30-billion water treatment plant in Teresa, Rizal, opting instead to relocate the facility within its concession area.
The Teresa plant, originally designed to source water from the Kaliwa Dam and to produce 300 million liters per day of potable water, has been put on hold, Maynilad said.
“The plan was to build a Teresa treatment plant to get water from Kaliwa Dam. We’ve shelved it for now. We plan to relocate it within our concession,” Maynilad COO Christopher Jaime Lichauco told reporters last week.
Lichauco said the project may take three to four years to complete.
“It’s going to be more efficient for us, because the NRW (non-revenue water), all the way from Teresa to our concession, with the new relocation it’s got to be more efficient,” he said.
NRW is defined as water that is not billed and is lost through leaks or illegal connections.
Maynilad president and CEO Ramoncito Fernandez said building another water source is part of the company’s business plan.
The development is “more of relocating the Teresa plant to our concession to avoid additional non-revenue water,” he said.
In 2025, Maynilad said it cut NRW to an average of 34.9 percent, with year-end losses at 30.7 percent. The reduction translated into the recovery of 256 million liters of water per day.
Fernandez last week said the company is ramping up investments to cut water losses further, targeting a reduction at 20 percent by 2030 in line with global standards.
Asked if the firm has near-term plans for desalination, Fernandez said: “Maybe not near term, but we have started looking at it way back but there are concrete opportunities for us to go for desal specifically in adjacent areas in Manila Bay.”
“Starting with the reclamation that can be a feasible area or desalination can work,” he added.
The Pangilinan-led company reported a consolidated net income of P15.2 billion in 2025, up by 19 percent from the previous year.
