Maynilad spends P102M to upgrade Putatan water treatment plant
West Zone concessionaire Maynilad Water Services, Inc. (Maynilad) said it has spent P102 million to upgrade its water treatment plant in Muntinlupa City, which will enhance supply reliability for its customers in the south.
The plant upgrade involved the installation of additional Reverse Osmosis (RO) assemblies at Putatan Water Treatment Plant (PWTP), increasing the facility’s RO treatment capacity to 50 million liters per day (MLD) from only 30 MLD.
Maynilad’s PWTP produces an average of 150 MLD of potable water for its 1.2 million customers in Muntinlupa, Las Piñas and Cavite.
PWTP particularly 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.
“With the recent installation of additional RO assemblies at PWTP, Maynilad can better sustain the facility’s production levels despite the varying quality of raw water from Laguna Lake,” the company said.
Maynilad is also currently constructing a second water treatment plant in Muntinlupa, which will provide an additional 150 MLD of potable water for the south where some areas still remain unserved and under-served.
