Maynilad’s P11-B new Muntinlupa treatment facility ready by Dec

MANILA  -Maynilad Water Services Inc.’s third water treatment plant that sources raw water from Laguna Lake will begin partial operations by year-end, after the company announced that it had started testing and gradual commissioning of the facility to ensure adequate water supply within its concession area.

In a statement over the weekend, Maynilad said the P11-billion Poblacion Water Treatment Plant was 80 percent complete and slated to produce an initial 50 million liters per day (MLD) of potable water by December for customers in the cities of Parañaque, Las Piñas and Muntinlupa, as well as Cavite province.

At full capacity, the facility located in Muntinlupa is designed to produce 150 MLD —equivalent to water is enough to fill around 60 Olympic-sized swimming pools and enough to serve about 1 million customers.

“This facility will help enhance service reliability, as it will provide additional supply for customers in the south so their water service will not be affected despite raw water quality shifts in Laguna Lake, which have been occurring with more frequency owing to climate change effects,” Maynilad said.

Construction of the plant began in 2022 with the aim of increasing available supply for distribution in southern Metro Manila.The Poblacion facility will source raw water from Laguna Lake, similar to two other plants located in Barangay Putatan, Muntinlupa, that produce a combined 300 MLD of water supply for around 1.7 million customers.

Maynilad earlier said it would rely on the Poblacion plant to provide buffer capacity and ensure uninterrupted service even as maintenance activities cut supply.

Las Piñas and some areas in Cavite province are expected to experience 13-hour service interruptions until Nov. 2 as Maynilad upgrades the Putatan Water Treatment Plant in preparation for the rainy season, when the turbidity level of raw water in Laguna Lake typically increases.

The company operates two other treatment plants at the La Mesa Compound in Quezon City that gets raw water from Angat Dam. INQ
