Muntinlupa City lone district Rep. Jaime Fresnedi is eyeing a congressional inquiry on the alleged persistent water service interruptions in his city under west zone concessionaire Maynilad Water Services.

In a statement Friday, April 10, Fresnedi expressed concern over the recurring water interruptions that continue to disrupt daily life across the city. He says it has affected households, businesses, and even government operations.

“Based on my interviews with my constituents, it doesn’t feel like there should be a water tanker roaming around every time there are water service interruptions. Shouldn’t they be there right away?” he said.

Fresnedi, a member of the House Committee on Metro Manila development, raised the issue amid the hot summer months, when water service was even more essential.

The solon further recalled that during a town hall meeting held last month, Maynilad had committed to coordinate with city officials to ensure the prompt deployment of water tankers for emergency distribution whenever faucets run dry.

However, Fresnedi said this promise has yet to materialize. “Unfortunately, it’s not being done. There are no water tankers seen circulating. That is the general sentiment,” he said.

As such, he says his legislative team is compiling relevant data as part of preparations for a formal resolution seeking a House probe aimed at determining accountability and improving service delivery in Muntinlupa.

The lawmaker said that the disruptions have forced residents—especially those with work obligations the following day—to stay up late waiting for water, a condition he said should not be tolerated.

“Many residents, especially those with jobs in the following day, are staying up late just to wait for water, which should not be the case,” said Fresnedi, who vowed to push for stronger oversight and corrective action.

Fresnedi also urged Maynilad to undertake meaningful improvements to stabilize service, as he pointed out that the repeated outages have already caused significant stress, inconvenience, and lost productivity among residents.

He also addressed Maynilad’s explanation that water quality from Laguna Lake has been deteriorating. According to Fresnedi, such claims are being used to justify ongoing unannounced interruptions, despite the continuing impact on the city.

Maynilad has maintained that it is working to address the situation through upgrades and investments, including new machinery and other operational improvements. However, Fresnedi said these efforts have not produced noticeable service improvements in recent weeks.

The majority congressman also called on the Metropolitan Waterworks and Sewerage System (MWSS), the regulator of water concessionaires, to exercise its full authority to ensure compliance.

“I hope that our water regulator should practice pro-active measures that will compel the water concessionaires to deliver a stable and efficient water services for our people. And that its power should not be limited to just imposing penalties,” he said.

Last month, Muntinlupa City Mayor Ruffy Biazon and other city officials demanded that Maynilad present a concrete service recovery plan to address recurring water interruptions affecting residents, businesses, and local government operations.

In two letters dated March 11, 2026, Biazon invited Maynilad President and Chief Executive Officer (CEO) Ramoncito Fernandez and Chief Operating Officer (COO) Christopher Lichauco to a meeting to address prolonged supply problems and outline both immediate and long-term measures to improve service reliability.

City officials said the continued outages have raised concerns regarding Maynilad’s operational response, customer communication, and coordination with local stakeholders, particularly as residents face uncertainty over outage schedules and restoration timelines.
