About the PIDr:

From December 2021 to February 2022, Maynilad Water Services, Inc. implemented Water Service Interruptions (WSIs) at the supply zone of its Putatan Water Treatment Plant in four (4) cities in Metro Manila (Parañaque, Las Piñas, Muntinlupa, and Pasay); and in five (5) cities/municipalities in the province of Cavite (cities of Bacoor, Imus, and Cavite; and municipalities of Rosario and Noveleta).

In January 2022, the MWSS RO conducted an investigation to determine whether there is a ground to declare Maynilad to have failed contractually on its service obligations, and to impose the appropriate penalties on the Concessionaire, in relation to the said WSIs.

On 22 February 2022, the MWSS RO through RO Resolution No. 2022-02-CA, resolved to impose a financial penalty on Maynilad, for its unusual and prolonged WSIs from December 2021 to February 2022, attributable to the failure of its Putatan Water Treatment Plants (PWTP).

Based on the evidence gathered from its investigation, the MWSS RO concluded that Maynilad 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.

In its efforts to promote transparency and accountability in governance, the MWSS RO will hold a 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.
