Residents across Metro Manila, Rizal and Cavite are advised to prepare for a series of water service interruptions this week. Manila Water Company Inc. And Maynilad Water Services Inc. Announced on Sunday that these disruptions are necessary due to scheduled maintenance works and high demand.
Infrastructure Maintenance and Leak Detection
Manila Water has scheduled several nighttime interruptions between 10 p.m. And 4 a.m. To facilitate essential repairs and testing. From May 11-12, service will be affected in sections of Brgy. Fortune in Marikina City for line maintenance at Bonanza St., as well as in Brgy. Pinagbuhatan in Pasig City and Brgy. Sta. Ana in Taytay, Rizal, for leak-detection step testing.
In Quezon City, interruptions are slated for May 12-13 in the villages of Sauyo, Tandang Sora, and Pasong Tamo to install pressure release valves. During the same window, Brgy. Bagong Pag-Asa will undergo step testing at North Avenue cor. Agham Road, and Brgy. Culiat will see a line meter replacement.
Further works in Quezon City and San Juan will occur May 13-14, affecting Brgy. South Triangle for step testing along T. Morato Ave. Cor. Timog Ave., and Brgy. Bagong Lipunan ng Crame and Brgy. West Crame for line meter replacements.
Regional Service Disruptions
Taguig City will experience interruptions in Brgy. Western Bicutan on May 12-13 for line valve repair, followed by Brgy. Tuktukan on May 13-14 for fire hydrant and line meter replacements near Bagong Calzada Street.

Rizal province will see various interruptions, including Brgy. San Roque and Brgy. Bagong Nayon in Antipolo on May 12-13. In Rodriguez, Brgy. San Isidro will have interruptions on May 13-14 for interconnection works at Southville 8B, while Taytay, Angono, and Binangonan will face zero pressure testing on May 14-15.
Maynilad has announced significant works affecting Las Piñas, Muntinlupa, and Parañaque between May 14-17. These outages, caused by the Putatan Water Treatment Plant upgrades, will affect Talon Uno and Talon Singko in Las Piñas, as well as various villages in Muntinlupa and Parañaque, including BF Homes and Alabang.
Manila and Cavite Network Works
In Valenzuela City, the villages of Gen. T. De Leon and Parada will face interruptions on May 11, 12, and 15 for network repair. In Manila City, extensive leak exploration will occur from May 11-18 in Binondo, Pandacan, Sampaloc, Santa Cruz, and Tondo.
Cavite residents in Bacoor and Imus will also be affected. Villages in Molino, Queens Row, and San Nicholas III in Bacoor, along with Pasong Buaya I and II in Imus, will have no water May 14-16 from 12 p.m. To 10 p.m. Due to the Putatan plant activities.
Potential Next Steps
Following the completion of these maintenance cycles, the water utility companies may see a reduction in system leaks due to the extensive exploration and step testing. The replacement of ATS systems and desilting at the Putatan plants could lead to more stable operations at those facilities.

Depending on the results of the zero pressure and step testing, technicians might identify further areas requiring immediate repair, which could lead to additional scheduled maintenance in the coming weeks.
