Cebu City explores solar-powered solutions against El Niño

MANILA, Philippines — The Cebu City Government is evaluating solar-powered technologies for water supply and agriculture as part of its efforts to strengthen climate resilience and prepare for the potential effects of El Niño.

Mayor Nestor Archival witnessed demonstrations of two renewable energy-driven systems: a solar-powered desalination unit designed to convert brackish water into usable freshwater and a solar water pump irrigation system intended to support agricultural production while reducing dependence on conventional power sources.

“We continue to explore innovative and sustainable solutions to help Cebu City prepare for the challenges of water security, especially with the looming threat of El Niño,” Mayor Archival said.

The desalination technology, presented by NXTLVL Water at Pond A of the South Road Properties (SRP), is being studied as a possible alternative water source for the city, particularly during periods of limited supply.

Present during the demonstration were engineers Denver John Turtoga, Takashi Hiramatsu, and Kimberly Limpahan, along with Prettie Acop Jalang of GUUN Co., Ltd., and Engr. Myka Marie A. Llanos of the Cebu City Environment and Natural Resources Office.

According to the City’s Public Information Office, the equipment is capable of treating brackish water, which contains higher salt concentrations than freshwater and is commonly found in coastal areas.

The technology could help supplement existing water sources, especially during drought conditions and in areas affected by saltwater intrusion.

“Para nato kini sa mas maayong pagpangandam sa atong siyudad. We need to study practical, sustainable, and energy-efficient technologies that can help address our water needs and support our long-term environmental goals,” the mayor added.

In a separate presentation, representatives of BMT Marketing introduced a Solar Water Pump Irrigation System that uses solar energy to power water pumps for agricultural irrigation.

The system is being considered as a potential tool to improve farmers' access to water while lowering operating costs associated with electricity and fuel consumption.

Archival said the city is committed to studying practical and sustainable technologies that can help address both water security and agricultural needs.

He noted that as Cebu City prepares for the challenges posed by climate variability, local officials must evaluate solutions that are energy-efficient, environmentally responsible, and responsive to community needs.

“Importante nga atong hatagan og pagtagad ang mga teknolohiya nga makatabang sa atong mga mag-uuma, makapamenos sa operational costs, ug makasuporta sa mas responsable nga paggamit sa atong natural resources,” he stressed.

The mayor added that any potential adoption of the technologies would undergo proper assessment to determine their suitability and long-term benefits for farmers and other residents.

These moves form part of the city's broader vision of building a smart, sustainable, and inclusive Cebu City through innovation and responsible resource management.

The city's interest in desalination comes amid growing concerns about the possible impact of El Niño on water resources.

The Metropolitan Cebu Water District (MCWD) has since secured additional water sources, including desalinated water and groundwater, to cushion the effects of anticipated supply reductions during prolonged dry conditions.

The country’s weather bureau, PAGASA, has also warned that El Niño could bring below-normal rainfall, increasing pressure on water resources across the region. — /IHM (FREEMAN)
