ILOILO City — Filipino-developed technologies capable of producing thousands of liters of safe drinking water are being promoted by the Department of Science and Technology (DOST) as affordable solutions to looming water shortages, particularly in vulnerable communities across Western Visayas, as the country braces for the anticipated effects of El Niño.
DOST secretary Renato Solidum Jr. said locally engineered water purification and desalination systems could help local government units secure alternative sources of potable water without relying heavily on expensive imported technologies.
The initiative comes amid projections of below-normal rainfall beginning this October, with drought conditions expected to intensify and potentially peak in February and March 2027.
Speaking during a press conference in Kalibo, Aklan, Solidum highlighted two Filipino-developed innovations designed to address drinking water shortages in disaster-prone, coastal, island and geographically isolated communities.
Among them is SAFEWATRS, or Safe Water Treatment System, a compact, solar-powered mobile purification unit developed through DOST’s Industrial Technology Development Institute (ITDI).
The technology can produce up to 2,000 liters of safe drinking water within nine hours, making it a potentially valuable emergency water source for communities experiencing shortages.
Because it operates using solar energy, the system can be deployed even in areas without reliable electricity, including remote barangays and communities affected by disasters.
Its compact and mobile design also allows the equipment to be transported to areas where conventional water supply infrastructure is unavailable or disrupted.
TURNING SEAWATER INTO DRINKING WATER
Another innovation being promoted by DOST is a locally developed desalination system capable of converting seawater and brackish water into potable water.
The technology is particularly suited for coastal and island communities where freshwater resources are limited despite their proximity to abundant seawater.
According to DOST, the basic desalination unit can produce 40 liters of drinking water per hour.
Its modular design allows local governments and communities to increase production by installing additional reverse osmosis modules as demand grows.
This flexibility could enable smaller communities to begin with modest water production capacities and gradually expand their systems according to their requirements and available resources.
The technologies offer practical alternatives for local governments seeking to strengthen water security without immediately undertaking costly, large-scale infrastructure projects.
Their promotion also reflects DOST’s push to make Filipino scientific innovations more accessible to communities facing increasingly unpredictable climatic conditions.
LOCAL SOLUTIONS TO A GROWING PROBLEM
Solidum emphasized that homegrown technologies should form part of broader preparations against El Niño, which could strain existing water sources and threaten essential services.
The anticipated dry spell is expected to place additional pressure on communities dependent on rainfall, groundwater and other vulnerable freshwater sources.
For Western Visayas, where agricultural communities and island municipalities face varying water supply challenges, the technologies could provide additional options for addressing shortages.
DOST has directed its regional offices to mobilize adaptation measures covering water supply, agriculture, health, energy and public safety.
Under its water security initiatives, the agency is promoting SAFEWATRS and modular desalination technologies as potential interventions for communities vulnerable to drought and water scarcity.
The department is also highlighting solar-powered mobile irrigation equipment to help farmers conserve water while sustaining agricultural production.
A solarized irrigation trailer, which can be transported between farms, allows smallholder farmers to share irrigation resources without requiring permanent and expensive installations.
DOST experts are likewise providing technical guidance on micro-irrigation and low-volume watering practices to reduce unnecessary groundwater consumption.
TECHNOLOGY ALONE NOT ENOUGH
Despite the availability of these innovations, Solidum stressed that technological solutions must be accompanied by responsible water consumption and collective action.
“Essentially, the bottom line is that everyone should be involved, even ourselves—magtipid sa paggamit ng tubig,” Solidum urged.
His appeal underscores the importance of water conservation even as government agencies explore alternative sources of potable water.
With the anticipated effects of El Niño expected to worsen in the coming months, the agency is encouraging communities and local governments to strengthen preparedness rather than wait until water shortages become severe.
DOST showcased its locally developed technologies during the 2026 Regional Science, Technology, and Innovation Week held from October 1 to 3 in Kalibo, Aklan.
The event brought together researchers, students, government officials and community leaders to promote scientific collaboration and technological innovations addressing regional development challenges.
As Western Visayas prepares for possible water shortages, DOST’s initiative highlights the potential of Filipino ingenuity to provide practical, affordable and adaptable solutions to one of the region’s most pressing environmental challenges.
The agency’s push also places greater emphasis on translating scientific research into technologies that local governments can adopt to protect communities against climate-related emergencies./PN
