Water concessionaires say stepping up readiness for super El Niño

MANILA — Metro Manila’s water concessionaires said they are speeding up infrastructure expansion and supply diversification in preparation for an anticipated El Niño dry spell stretching into 2027.

West Zone concessionaire Maynilad Water Services said that when the water level at Angat Dam—the principal source of raw water for Metro Manila—fell to 150.42 meters, it was able to sustain its services sans interruption.

Maynilad noted that the July drop in Angat’s water level was even lower than the 157.96 meters recorded during the country’s severe 2019 water crisis, which forced widespread rationing across Metro Manila and nearby provinces.

The utility said it has managed to avoid supply interruptions despite the historic drop, as it reduced network leaks and developed alternative water sources. The company said it reduced daily water losses by more than 150 million liters compared to 2025, lowering its operational reliance on Angat from 100 percent historically to about 83 percent.

Although monsoon rains pushed reservoir levels back above 207 meters, Maynilad said that continued preparations are vital.

“The experience earlier this year showed why we have been investing in a more resilient water supply system,” said Maynilad Chief Operating Officer Christopher Jaime Lichauco.

East Zone distributor Manila Water said it is also expanding its alternative raw water facilities to bolster resilience ahead of the prolonged dry period.

The Razon-led utility said it is nearing completion of its 200-million-liter-per-day (MLD) East Bay Phase 2 project sourcing water from Laguna Lake, following the installation of 31.5 kilometers of submarine transmission pipelines. Combined with Phase 1, the development will supply 250 MLD to the network.

Manila Water is also completing the 220-MLD Kaysakat Water Treatment Plant in Antipolo City to treat raw water from the Wawa Dam system.

“Preparing for a possible strong El Niño requires more than short-term measures. It requires continuous investments in more sustainable raw water sources that can help ensure a reliable water supply despite changing climate conditions,” said Dittie Galang, Manila Water Corporate Communications Group Head.

The Philippines is bracing for a “very strong” El Niño which could significantly affect rainfall and water resources across the country.

Weather bureau PAGASA said about 45 provinces will experience dry conditions while eight provinces will face drought.
