About the PIDr:

From May to July 2022, the MWSS RO monitored prolonged and recurring water service interruptions and water quality issues in the southern part of the West Concession Area. Based on the evidence gathered by the MWSS RO in its investigation into the prevailing water supply conditions in the West Zone, Maynilad Water Services, Inc. (Maynilad) was found to have breached its service obligation of ensuring the availability of an uninterrupted twenty-four (24) hour supply of water at seven (7) pounds per square inch (psi) minimum pressure for more than 15 days to connected customers in parts of Las Piñas City, Muntinlupa City, Parañaque City, and Cavite Province’s Bacoor City, Imus City, Cavite City, Noveleta, and Rosario.

In light of these findings, the MWSS RO, through RO Resolution No. 2022-12-CA, has resolved to impose a financial penalty on Maynilad in the amount of nine million two hundred sixty-four thousand three hundred fifty-eight pesos (PHP 9,264,358) for the continued water service interruptions within the Putatan Water Treatment Plant (PWTP) supply zone.

In its efforts to promote transparency and accountability in governance, the MWSS RO, in cooperation with Maynilad, will hold a Public Information Drive (PIDr) on the Rebate Program for Affected Maynilad Customers within the Supply Zone of Putatan Water Treatment Plant.

The PIDr on the Rebate Program aims to:

1. provide information on the nature, scope, and other details of the implementation of the Rebate Program to the affected men and women Maynilad account holders in Metro Manila and Cavite;

2. explain and clarify the bill rebates;

3. address (gender-related) issues and concerns of affected account holders; and

4. elicit comments and suggestions on improving gender-responsive services, especially in relation to water supply management.
