Muntinlupa residents have experienced daily water service interruptions (WSI) from Maynilad Water Services Inc. again.

Since June 2, Maynilad customers in Muntinlupa and other areas have suffered from no water supply from eight to 18 hours a day.

In one advisory sent to customers in Muntinlupa, Maynilad said it imposed the WSI “due to raw water quality issue from Laguna Lake even as we conduct system adjustments to optimize the limited supply.”

Last June 4, Maynilad implemented WSI from 12 noon until 6 a.m. on June 5 for a total of 18 hours, affecting customers in “portions of Brgy. Talon Dos, Las Pinas City and Brgys. Alabang, Bayanan, Poblacion, Putatan and Tunasan, Muntinlupa City.”

Maynilad has its Putatan Water Treatment Plant (PWTP) in Barangay Putatan, Muntinlupa, which sources raw water from Laguna Lake.

The treatment plant supplies water to Maynilad customers in Muntinlupa, Parañaque, Las Piñas, and Pasay; and the cities of Bacoor, Imus and Cavite, and municipalities of Rosario and Noveleta in Cavite.

Last February, the Metropolitan Waterworks and Sewerage System-Regulatory Office (MWSS-RO) imposed a financial penalty of P63.97 million on Maynilad for implementing WSI in the supply zone of the Putatan Water Treatment Plant from December 2021 to February 2022.

MWSS-RO said the penalty was imposed on Maynilad after the company “failed to meet its Service Obligation of ensuring the availability of an uninterrupted 24 hour supply of water at seven (7) pounds per square inch (psi) minimum pressure to all connected Customers in its Service Area.”

“Customers within the PWTP Supply Zone were found to have been deprived of water service obligation for at least fifteen (15 days), which adversely impacted their health and welfare. The MWSS RO is set to implement the financial penalty in the form of bill rebates to affected Maynilad customers within the PWTP’s Supply Zone by April,” according to MWSS-RO.

As a result, 198,315 Maynilad customers being serviced by the water treatment plant got a rebate of P323 each that was deducted from their monthly bills.
