As the threat of an intensifying El Niño raises the prospect of prolonged dry conditions and water shortages, Cebu City and Mandaue City are putting their barangays on the front line of preparations.
In Cebu City, barangay-based emergency responders have been directed to identify and document alternative water sources within their communities, turning local knowledge into a key component of the city's contingency planning.
The assignment was formalized during a coordination meeting led by the Cebu City Disaster Risk Reduction and Management Office (CCDRRMO), bringing together city officials, partner agencies and task force members to prepare for possible water-supply disruptions.
Responders will survey artesian wells, water-refilling stations, existing facilities and other potential sources that could be tapped during shortages. They are expected to assess each source according to accessibility, availability and usability, with the findings to be consolidated by city offices and Task Force El Niño.
The strategy recognizes a practical reality in disaster management: a citywide water plan is only as useful as the information available at the community level.
A water source that is unknown to city planners, inaccessible to emergency teams or unsuitable for human consumption cannot be counted as an effective reserve. By requiring barangays to identify potential sources in advance, Cebu City is attempting to build a more detailed picture of where emergency water may actually be obtained when conventional supplies come under pressure.
Mayor Nestor Archival emphasized the importance of barangay-level data in mapping and mobilizing resources if water scarcity becomes more severe.
The urgency is underscored by the latest climate outlook. PAGASA said in its September 23 advisory that a strong El Niño is active and is expected to intensify into a very strong event during the September-December period and persist through the first half of 2027.
Earlier PAGASA outlooks for Central Visayas likewise warned of below-normal rainfall as El Niño strengthens, with an 81 percent probability of a strong event developing between October and December 2026 and continuing into early 2027.
For Cebu, the potential consequences are particularly significant because water demand is concentrated across a highly urbanized area.
The Metropolitan Cebu Water District has projected that worsening conditions could produce a daily water-supply deficit of about 43,000 cubic meters, with reduced production from sources including Buhisan Dam, the Cotcot and Lusaran rivers and the Jaclupan facility.
That makes water conservation and alternative sources more than emergency measures. They become part of a broader effort to keep households, businesses, farms and critical facilities functioning during an extended period of water stress.
From emergency response to long-term water security
Cebu City's preparations build on recommendations from its El Niño Summit, which called for action across three time horizons.
Immediate measures include repairing damaged water facilities, reviewing emergency supplies and updating contingency plans. Medium-term measures include rehabilitating wells, expanding storage and improving irrigation and distribution systems.
The longer-term agenda is more ambitious: sustainable citywide water systems, additional reservoirs, water-recycling facilities and watershed rehabilitation.
The distinction is important.
Emergency water deliveries can address an immediate shortage, but they cannot by themselves solve structural weaknesses in a city's water system. The longer the dry period lasts, the more important storage, alternative sources, conservation and watershed protection become.
Mandaue prepares for the same threat
Mandaue City is pursuing a similarly broad approach, with its own El Niño action plan covering water, health, agriculture, fire prevention and disaster response.
City Administrator Atty. Gonzalo Malig-on Jr. said the plan consolidates proposals from city department heads and has been approved by the City Disaster Risk Reduction and Management Council. The focus, he said, is now on implementation should conditions worsen.
Water shortage is at the center of the plan.
Mandaue is considering the procurement of water tanks and filtration systems, including mobile filtration systems intended for its 27 barangays. The systems could be used for water rationing if shortages become severe.
The City Engineer's Office is also expected to monitor water lines for leaks and unnecessary losses, while plans include a water detention tank for storage and conservation during dry conditions.
At the barangay level, officials are expected to monitor communal water sources and deep wells, conduct water-conservation campaigns and establish cooling areas in barangay halls and covered courts.
Barangay disaster risk reduction committees are also tasked with activating emergency operations centers, checking equipment and prepositioning supplies such as drinking-water containers, first-aid materials and electric fans.
The preparations extend beyond water.
Mandaue's plan includes fire prevention measures, health surveillance and agricultural interventions. Barangays are expected to maintain monitoring of potential fire hazards, while the City Health Office will activate its El Niño response team when necessary and monitor health facilities and disease reports.
The agriculture component includes adjusting crops, conserving soil moisture, promoting rainwater harvesting and supporting drought-resistant crops. Livestock and poultry measures include ensuring adequate water, improving ventilation and managing heat stress.
The barangay as the first line of resilience
The two cities' preparations illustrate why barangays are increasingly important in climate and disaster planning.
National agencies provide forecasts. City governments develop contingency plans. Water districts manage supply systems. But barangays are where water shortages, heat stress, fires and health risks are first experienced by households.
That makes local information indispensable.
A barangay that knows the location and condition of its wells, the capacity of its communal water sources and the needs of vulnerable households can provide city authorities with information that cannot easily be generated from a central office.
But local responsibility must be matched by resources.
Mapping water sources is useful only if those sources are tested, maintained and made accessible when needed. Filtration systems are useful only if there is a reliable water source and trained personnel to operate them. Emergency plans are meaningful only if equipment, supplies and communication systems are actually ready.
The challenge, therefore, is to prevent El Niño preparedness from becoming merely a collection of plans and inventories.
Cebu City's decision to require barangays to identify alternative water sources, coupled with Mandaue's plan to equip its 27 barangays for possible water rationing and other emergencies, reflects a shift toward localized preparedness backed by citywide coordination.
With PAGASA expecting El Niño to persist into the first half of 2027, the coming months will test whether these preparations can translate into sustained water conservation, faster response and more resilient communities.
For Cebu's cities, the message is increasingly clear: when water becomes scarce, resilience will depend not only on the capacity of major water facilities but also on how prepared each barangay is to protect, conserve and manage the water available to its residents. (Photo credit: STAR/Edd Gumban)
