Maynilad Water Services Inc. is reevaluating the location of its major treatment facility originally slated for Rizal, opting to move the project closer to its primary concession area to better integrate with the upcoming Kaliwa dam.

The West Zone concessionaire earlier earmarked ₱30 billion for the construction of the Teresa Water Treatment Plant. However, Christopher J. Lichauco, Maynilad chief operating officer, said the company has shelved the initial plan in favor of the site that offers better operational efficiency.

Lichauco said the relocation is intended to mitigate risks associated with non-revenue water—water that is produced but lost before it reaches the customer through leaks or theft—by shortening the distance the treated supply must travel.

The Kaliwa Dam, a flagship infrastructure project designed to provide a secondary water source for Metro Manila, is expected to be completed within two years. Maynilad’s relocated plant is projected for development over the next three to four years to coincide with the availability of the dam’s raw water supply.

Lichauco noted that keeping the facility within the company’s specific service boundaries ensures more direct control over the infrastructure.

While the large-scale Teresa project undergoes a pivot, Maynilad is nearing the finish line on its "New Water" facility in Pasay City.

Ramoncito S. Fernandez, Maynilad chief executive officer, said the facility, which recycles treated used water for potable use, is scheduled for completion this year.

Once fully operational, the Pasay plant is expected to produce 12 million liters per day, serving approximately 60,000 customers.

Fernandez clarified that while Maynilad is not looking to formally expand its concession boundaries, it is aggressively seeking partnerships with neighboring water districts.

The company aims to provide bulk water supply and wastewater services to industrial and commercial clients in adjacent provinces such as Bulacan and Cavite.

In the longer term, the utility is exploring desalination as viable solution for water security, specifically targeting areas along Manila Bay.

Fernandez said that the company is currently scouting for international partners to bring in the necessary technology.

He noted that the rapid evolution of desalination tech requires a diligent evaluation of foreign providers before committing to a final investment decision.
