Manila Water is stepping up operational preparations to ensure continuous water supply to customers in its East Zone concession throughout the habagat season, the company said. The utility is deploying enhanced protocols and infrastructure reinforcements designed to mitigate service disruptions during the southwest monsoon period.

While meteorological forecasts indicate reduced rainfall frequency due to lingering El Niño conditions, weather officials warn that isolated heavy precipitation events remain possible. Manila Water's preemptive approach addresses both drought and flood scenarios that could affect water availability and distribution systems.

The company's resilience strategy encompasses infrastructure maintenance, system monitoring upgrades, and contingency planning across its service territory. Officials emphasized that the measures aim to shield millions of customers across metro Manila's eastern areas from potential service interruptions.

The habagat season typically runs from June through September, though its intensity and timing can vary significantly depending on regional atmospheric conditions. Manila Water serves approximately 1.8 million customers in the East Zone, including portions of metro Manila and nearby provinces.
