Strong El Niño poses threat to Metro Manila water supplies

MANILA — Metro Manila faces mounting pressure on its water supply as a strong El Niño event brings extended dry weather to the Philippines, threatening to curtail water inflows into reservoirs that serve millions of residents across the capital region.

El Niño, defined by the Philippine Atmospheric, Geophysical and Astronomical Services Administration as a climate phenomenon marked by unusually warm sea surface temperatures in the Pacific Ocean, typically triggers below-normal rainfall and prolonged drought conditions across much of the country.

Water resources officials have flagged concerns that drier-than-usual conditions could significantly reduce the volume of water flowing into reservoirs that supply Metro Manila and surrounding areas. The potential constraints come as the region grapples with growing water demand from its expanding population.

Authorities are urging water utilities and consumers to prepare contingency measures, including water conservation efforts and alternative supply strategies. The timing of the El Niño event and its intensity over coming months will be critical factors in determining the severity of any supply shortages.

Metereological agencies continue monitoring atmospheric conditions to provide updated forecasts on the event's duration and regional impact.
