Select Maynilad customers to get rebates in April 2026

Select customers of west zone concessionaire Maynilad Water Services Inc. can expect rebates in their April 2026 bill, with some receiving zero bills, following the service interruptions recorded in the southern portion of its concession area in February.

This comes as the Metropolitan Waterworks and Sewerage System Regulatory Office (MWSS-RO) earlier decided to penalize Maynilad P42,569,790.85, which will be implemented through a bill rebate program equivalent to P432.92 per affected service connection.

The penalty was computed as the average water tariff times two cubic meters (cu.m.) per day for each affected connection, multiplied by the number of days.

The MWSS-RO said Maynilad failed to meet its service obligation to provide uninterrupted 24-hour water supply at a minimum pressure of 7 pounds per square inch (psi) from February 10 to 16, and 19 to 23, 2026.

With the penalties, this would mean that low-income lifeline customers — or residential and residential bulk customers who belong to the marginalized sector — would get a “zero bill” in April, as the rebates would be more than their monthly consumption.

Low-income lifeline customers with a 10 cu.m. consumption will have an extra P280.86, which means that Maynilad would still owe them the same amount that could be removed from the succeeding bill. Those consuming 20 cu.m. will have an extra P53.62.

For regular customers consuming 10 cu.m., they will have an extra P245.59, while those consuming 20 cu.m. will be charged P271.39.

“Unfortunately that’s the total amount that we can impose on them for this duration that is February,” MWSS-RO chief regulator Patrick Ty said during the public information drive on Friday.

“We are still investigating the issue. While we cannot commit that there will be further penalties, we can only confirm that there is an ongoing investigation again so we will not hesitate to impose additional financial penalties if warranted,” he added.

For its part, Maynilad explained that the treatment of raw water from Laguna Lake took longer due to “more challenging” raw water conditions amid the Amihan season, effectively reducing production and limiting supply in select areas.

Moving forward, the company said it is strengthening its supply in the southern portion of its concession area by upgrading its treatment plants, the distribution of available supply, and adding more water sources.

“Ito pong experience natin this year is mas nag-further deteriorate pa po ‘yung ating raw water quality sa Laguna Lake ngayong Amihan season and because of this experience, papaigtingin pa po namin or we will be further improving po ‘yung ating treatment capability ng ating existing plants dito sa south,” Maynilad Water Supply operations head Ronaldo Padua said during the information drive.

“At the same time po we will be constructing new water sources po para po meron pong tinatawag na redundancy during times ng mga ganitong extreme variability ng water quality,” he added.

(Our experience this year is that the raw water quality in Laguna Lake deteriorated further this Amihan season and because of this experience, we will be further improving the treatment capability of our existing plants in the south.

At the same time, we will be constructing new water sources so that there will be redundancy during times of extreme variability in water quality.)

Maynilad currently serves customers in the west zone, which covers the cities of Caloocan, Las Piñas, Makati, Malabon, Manila, Muntinlupa, Navotas, Parañaque, Pasay, Valenzuela and Quezon City.

It also services certain areas in Cavite such as the cities of Bacoor, Cavite, and Imus; and the towns of Kawit, Noveleta, and Rosario. —AOL, GMA Integrated News
