With Maynilad’s daily water service interruptions still going on in Muntinlupa City, Mayor Ruffy Biazon formally wrote to the executives of the water concessionaire about the problem, according to a Manila Bulletin news report.
To put things in perspective, posted below is an excerpt from the news report of the Manila Bulletin. Some parts in boldface…
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.
