Biazon writes to Maynilad president, COO about daily water service interruptions in Muntinlupa
Mayor Ruffy Biazon took the problem of the daily water service interruptions in Muntinlupa to the top executives of Maynilad Water Services.
Muntinlupa customers of Maynilad have been experiencing daily water service interruptions since February.
In its latest advisory, Maynilad told Muntinlupa customers, “Some areas of Brgys. Alabang, Bayanan, Poblacion, Putatan and Tunasan, Muntinlupa City may experience low to no water supply starting March 14, 2026 at 4:00 pm until March 15, 2026 at 7:00 am. This is due to sudden changes in raw water quality caused by strong winds over Laguna Lake during the Amihan season, which required operational adjustments in our treatment facilities. We are currently managing the limited supply and will restore normal service as soon as conditions improve. Mobile water tankers are being deployed in affected areas to assist customers. We apologize for the inconvenience and thank you for your understanding.”
Biazon sent letters to Ramoncito Fernandez, Maynilad president and chief executive officer; and Christopher Jaime Lichauco, chief operating officer, telling them that “once again, Maynilad has failed its customers.”
He said that the water service interruptions have been happening despite the fact that Maynilad has two water treatment plants in Muntinlupa, located in Barangays Putatan and Poblacion.
The mayor is asking Maynilad for a meeting to explain the situation, present steps to prevent it from happening again, and give consideration to affected Muntinlupa customers.
Due to the water service interruptions, the Metropolitan Waterworks and Sewerage System Regulatory Office (MWSS-RO) imposed a penalty against Maynilad amounting to P42,569,790.85 .
"Meanwhile, following the prolonged water service interruptions that occurred in the southern portion of the West Concession Area in February 2026, the MWSS RO conducted an investigation into the prevailing water supply conditions in the affected areas. Based on the evidence gathered, the MWSS RO found that Maynilad failed to meet its service obligation of providing an uninterrupted twenty-four (24)-hour supply of water at a minimum pressure of seven (7) pounds per square inch (psi) to 98,331 customers within the Putatan Water Treatment Plant and Poblacion Water Treatment Plant Supply Zones," Maynilad said in a press statemetn.
It said the penalty will be implemented in the form of bill rebates equivalent to P432.92 per affected water service connection, to be reflected in customers’ water bills by April this year.
Here is Biazon’s letters to Fernandez and Lichauco:
“Once again, Maynilad has failed its customers.
“A broken promise that has been repeated many times in many years, Muntinlupeños are forced to endure a waterless life by a service provider who has been given what is in effect a monopoly.
“What adds salt to an already festering wound is the fact that in Muntinlupa City, Maynilad has two water treatment plants right along the shore of Laguna de Bai.
“It is lamentable that Maynilad is unable to properly inform its customers about service interruption in a timely, efficient and effective manner. Muntinlupeños are caught off-guard and are unable to prepare. The uncertainty of service restoration also causes undue stress, inconvenience and lost productivity.
“Government itself is not spared from this failure to communicate by Maynilad. We are also in the dark on what is going on, which necessitates us to have to initiate contact with Maynilad instead of Maynilad proactively engaging the local government.
“While Maynilad claims to deploy tankers to provide emergency distribution, it definitely is not sufficient to support all your subscribers and the impact is not significantly felt.
“But the ultimate blow to Muntinlupeños is that in spite of this failure to provide reliable and uninterrupted service for such a basic need, they are still compelled to pay for it under threat of being disconnected.
“At the least, there should be a rebate to customers who have been deprived of the quality of service Maynilad is obligated to deliver to the people.
“It is in this light that I am calling on Maynilad senior management to attend a meeting with the Muntinlupa City Government to explain the service interruptions, the course of action Maynilad is taking to rectify its faults and prevent future occurrence as well as how the people will be compensated for the inconvenience, loss and failure to render service by Maynilad.
“We look forward to your prompt action on this matter. Thank you very much.”
