Maynilad Water Services Inc. is set to switch on its Putatan Water Treatment Plant 2 in Muntinlupa City in a move to improve water services within its coverage area.

In its advisory, Manila Water said the expanded Putatan treatment facility will be inaugurated on Monday which sources raw water from Laguna Lake.

This is “part of Maynilad’s water security program to minimize dependence on Angat Dam. This facility will boost water production and enable the company to improve and expand services in the southern part of the West Concession area,” it added.

In July last year, Maynilad announced the upgrade of the treatment plant which amounted to P102 million.

It involved the installation of additional Reverse Osmosis (RO) assemblies at Putatan Water Treatment Plant (PWTP) which, in turn, increased the facility’s treatment capacity to 50 million liters per day (MLD) from 30 MLD.

The treatment facility produces an average of 150 MLD of potable water for about 1.2 million Maynilad customers in Muntinlupa, Las Piñas and Cavite.

PWTP uses a multi-stage process to convert raw water from Laguna Lake to potable drinking water.

The facility uses its RO treatment process whenever there are spikes in Total Dissolved Solids (TDS) in the lake water.

Given the limited RO treatment capacity, PWTP often had to reduce water production with every shift in the lake’s raw water quality.


Currently, Maynilad is constructing a second water treatment plant in the city that will provide another 150 MLD of potable water for the south where some areas still remain unserved and underserved.
