TL;DR
Parts of Metro Manila and Rizal will face scheduled water service disruptions due to maintenance activities. The water agency has announced the schedule, aiming to improve service reliability.
Several areas in Metro Manila and Rizal will experience scheduled water service interruptions starting this week, as the local water utility conducts maintenance activities. The disruptions are part of ongoing efforts to improve the reliability of water supply systems, according to the Metropolitan Waterworks and Sewerage System (MWSS).
The MWSS announced that water service will be temporarily halted in specific districts within Metro Manila and Rizal from March 25 to March 30. The affected areas include parts of Quezon City, Mandaluyong, Marikina, and several municipalities in Rizal province. The agency stated that the maintenance aims to upgrade pipelines and improve water pressure, which has been inconsistent in some sectors.
According to MWSS spokesperson Maria Santos, “The scheduled maintenance is necessary to ensure long-term service stability and to prevent more frequent outages in the future.” The agency has coordinated with local government units to notify residents and businesses in advance. Water service is expected to resume gradually after the scheduled work is completed.”
Impacts on Residents and Local Economy
The scheduled water interruptions are significant because they affect daily life and economic activities in densely populated areas. Households will need to plan for water shortages, especially for cooking, cleaning, and sanitation. Businesses, particularly those in food service and healthcare, could face operational disruptions. The disruptions highlight ongoing challenges in infrastructure maintenance amid increasing demand for reliable water supply in Metro Manila and Rizal.

Recent Infrastructure Upgrades and Ongoing Maintenance
Water service interruptions in Metro Manila and Rizal are not uncommon, often coinciding with scheduled maintenance or emergency repairs. The MWSS has previously announced similar activities, citing aging infrastructure and the need for system upgrades. The current maintenance is part of a broader initiative to improve water pressure and reduce leakages, which have been persistent issues in the region.
Officials have emphasized that such scheduled works are essential for long-term service improvement, although they temporarily inconvenience residents. The last major maintenance activity took place in December 2023, which also caused widespread disruptions.
