West Zone concessionaire Maynilad Water Services, Inc. (Maynilad) inaugurated today, March 20, 2024, a modular treatment plant in Muntinlupa City that will treat raw water from Laguna Lake using state-of-the-art ceramic ultrafiltration (UF) technology, which is a “first” for water treatment in the Philippines.
Operated under a “build-operate-transfer” contract by Rendco-FFJJ Consortium, the Laguna Lake Modular Treatment Plant (ModTP) can produce 20 million liters per day (MLD) of potable water supply, augmenting the production of Maynilad’s three existing treatment facilities in Muntinlupa that also use Laguna Lake as a source.
The 20-MLD water supply from this additional facility will help to improve service reliability for Maynilad customers in the south, as its technologically advanced treatment processes ensure sustained production despite abrupt fluctuations in the lake’s raw water quality, which have been occurring with more frequency owing to climate change effects.
Besides the state-of-the-art Ceramic UF membranes, the facility also uses other key global treatment technologies, such as Ceramic Flatsheet Membranes, Nanobubble Technology, and Sludge Dewatering Press, all incorporated into a localized design that produces zero liquid discharge. This means that every drop of water is used and conserved.
The facility’s various treatment processes also require less maintenance and lower energy and chemical consumption, thus resulting in cost efficiencies and reduced environmental impact.
“Maynilad continues to adopt innovative solutions to meet the evolving water supply and treatment challenges, ensuring long-term resilience and sustainability. With this new facility, we are setting a milestone in municipal water treatment here in the Philippines, as we explore the potential of scaling similar technologies across other facilities,” said Maynilad President and CEO Ramoncito S. Fernandez.
The use of ModTPs that tap alternative sources to Angat Dam form part of Maynilad’s service enhancement program, which aims to address water security challenges.
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 towns of Kawit, Noveleta and Rosario, all in Cavite Province.
