On the afternoon of September 12, 2025, a few hours of rain were enough to bring parts of Quezon City to a halt. Major thoroughfares turned into waist-deep streams of brown water. Commuters abandoned stalled vehicles, holding their shoes and briefcases above the current as they waded home.
For many residents, the afternoon carried no shock. It was not a disaster but routine—the familiar script of a city that floods easily and recovers slowly, where each storm feels less like an emergency
than a reminder.
What makes the scene jarring is the arithmetic. From July 2022 to May 2025 the government announced about ₱545 billion in flood-control projects across the country, nearly half a trillion pesos devoted to dikes, drainage systems, pumping stations and river-widening works. Yet in Metro Manila, in the provinces and in lakeshore barangays, floodwater continues to dictate the daily headlines.
This is not merely an engineering failure. It is a gap of performance where political pledges, procurement systems and hydrology do not meet at the same table. To understand why so much money has not bought the safety it promised requires tracing three lines at once: what the projects were designed to do, why they fell short, and what research and practice point to as a more durable path ahead.
When spending outruns strategy
When politicians present ribbon-cuttings as proof of governance, they turn vulnerability into visible objects: concrete walls, pumping stations, canals. The visible has value, and structural works are often necessary. But the magnitude of spending obscures a pattern of execution that is partial, hurried and, at times, poorly recorded. Investigations and media reports published in 2025 point to thousands of projects filed under the flood-control program; many remain unfinished, built below standard or, auditors found, absent on the ground.
President Ferdinand Marcos Jr., in announcing an independent inquiry into infrastructure anomalies, captured the political mood when he pledged at a press briefing, “They will not be spared.” The statement signaled that the probe was meant to be consequential. How consequential it proves to be will determine whether the public’s half-trillion-peso question is met with facts or with more promises.
Accountability, however, is not an abstract demand. The Commission on Audit has documented procurement practices riddled with red flags: bidding processes won by the same favored contractors despite glaring performance issues, subcontracting chains that blur responsibility, and projects awarded under “negotiated procurement” that conveniently sidestep competitive transparency. In some cases, barangay-level officials are drawn into patronage webs, pressured to endorse projects in exchange for political loyalty, only to be left explaining to residents why canals remain clogged and pumping stations inoperable.
In public hearings this year, the controversy acquired names. Contractors Pacifico “Curlee” Discaya and his wife Cezarah “Sarah” Discaya testified before the Senate Blue Ribbon Committee, alleging that lawmakers and DPWH officials routinely demanded kickbacks of “no less than 10 percent and even up to 25 percent” of contract values—claims the couple said they documented and offered to corroborate in closed hearings. “We fear for our safety because we don’t have protection yet,” Pacifico Discaya told the committee.
COA audits have already produced formal referrals: fraud-audit reports on several Bulacan flood-control projects were filed with the Office of the Ombudsman after COA flagged irregularities in projects contracted to firms such as Wawao Builders and others. Local reporting and COA statements list district engineers and three contractors as liable in Bulacan cases.
The Senate probe has named dozens of legislators and officials in testimony by former DPWH engineer Brice Ericson Hernandez and others; two senators: Jinggoy Estrada and Joel Villanueva were publicly implicated in testimony and have denied the allegations. The presence of named actors, and the appearance of campaign contributions from some contractors in 2022 election records, sharpens the need for both forensic audit and rapid judicial inquiry where the evidence warrants.
President Marcos released a list of 15 contractors that received a disproportionate share of flood-control allocations (20% of the ₱545B program). These firms and their project shares have been focal points for investigators and journalists:
1. Legacy Construction Corporation
2. Alpha & Omega Gen. Contractor & Development Corp
3. St. Timothy Construction Corporation
4. QM Builders
5. EGB Construction Corporation
6. Topnotch Catalyst Builders Inc.
7. Centerways Construction and Development
8. Sunwest, Inc. (GMA)
9. Hi-Tone Construction & Development Corp.
10. Triple 8 Construction & Supply, Inc.
11. Royal Crown Monarch Construction & Supplies Corp.
12. Wawao Builder
13. MG Samidan Construction
14. L.R. Tiqui Builders, Inc.
15. Road Edge Trading & Development Services
The street-level evidence
If statistics describe the inputs, the streets reveal the outputs—and those outputs remain blunt. Short, intense downpours now overwhelm drainage systems built to older standards. In August 2025, the public works secretary told lawmakers that Metro Manila still lacks a unified drainage master plan and that much of the existing network is “very much old” and clogged with silt, its capacity sharply reduced. In practice, infrastructure built for yesterday’s storms is being asked to withstand climate-driven extremes.
The consequences are not abstract. Floods deepen inequality. For many low-income families, a single inundation can ruin appliances and livelihoods, contaminate water supplies and halt children’s schooling. In Barangay Tatalon, Quezon City, a mother of three described how each storm means dragging her refrigerator to higher ground and sleeping on damp mats while waiting for waters to subside—“isang ulan, isang linggong gastos,” she told ABS-CBN reporters, the math of disaster collapsing into a week’s worth of lost income and repair bills.
In Malabon, the tide of disruption spills into classrooms. On August 11, 2025, six schools including Col. Ramon Camus Integrated School and Malabon City Science & Mathematics High suspended face-to-face classes as high tide crept into hallways. Teachers scrambled to upload modules, but many students lacked power or stable internet to keep pace. By late June, another cluster of schools had already shifted online when floods made even the short walk to school dangerous, the river of disruption cutting across generations of learners.
For commuters, the toll is measured not in destroyed homes but in eroded hours. Jeepney driver Ernesto, 52, spends nights trapped in gridlock when Taft Avenue becomes a canal; what was once two shifts of earnings dwindles into one, his boundary fees unchanged, his passengers irate. He is not alone: in mid-2025, the Pasang Masda drivers’ association reported that entire routes were underwater, leaving operators unable to work for nearly a week, a livelihood drought relieved only by food packs from the DSWD.
And for riverside residents, floods carry not only financial but medical consequences. In Barangay Ibaba, Malabon, waters rose to twenty-six inches along C. Arellano Street, trapping light vehicles and pushing families onto upper floors. Local health officials quickly issued alerts for leptospirosis and dengue, warning that stagnant pools had become breeding grounds for disease.
These are the recurring, uneven costs that budget figures cannot capture. They accumulate quietly in debt cycles, in missed lessons, in a jeepney driver’s empty pocket or a mother’s broken washing machine even as officials tally “completed projects” and procurement awards. They are, as one
Rappler editorial put it, the “shadow ledger” of Philippine infrastructure: the hidden costs borne daily by those least buffered against climate and bureaucracy alike.
Structural breakdowns
Experts and audits point to overlapping structural issues that explain the performance gap:
Fragmented, project-based work instead of system-level planning. Many interventions remain localized: a canal here, a pump there without accounting for watershed dynamics. Water pushed back upstream or diverted from one barangay often resurfaces elsewhere. The lack of a Metro Manila drainage master plan illustrates this fragmentation.
Design standards lagging behind a changing climate. Infrastructure has long been built to “25-year” or similar return-period standards. Climate science now renders those thresholds unreliable. The result is structures overtopped by storms more severe than their design ever anticipated.
Implementation and procurement weaknesses. Audits and reports in 2025 suggest that a small group of contractors captured a disproportionate share of the flood-control budget. Many projects, reviewers found, carried inconsistent documentation or fell short of standards, raising questions of both governance and performance.
Ecological degradation and urban encroachment. Rivers narrowed by development, wetlands filled for housing or commerce, and mangrove belts cut or degraded have erased natural buffers that once softened floods. Without restoring these systems, gray infrastructure is left to fight a losing battle.
Climate trajectory
Where structural failures expose today’s limits, climate projections chart the scale of what is to come, and it is not comforting. Models calibrated by PAGASA and international research consortia universally warn of increasing rainfall intensity, greater variability, and the erosion of “rare event” design assumptions.
Case in point: an article in ScienceDirect projects that some weather stations in Luzon and Visayas may see extreme precipitation events (95th percentile storms) increase by up to 80%, compared to the baseline in the early 2000s. Another study using hydrologic simulations for the Angat watershed under high-emission scenarios (RCP8.5) shows that peak wet-season reservoir inflows could decline by up to 18% by 2036–2065, even as rainfall becomes more erratic and concentrated.
The CliMap downscaling models hosted by PAGASA reveal that many parts of the country, especially lower‐lying Luzon, Eastern Visayas, and Mindanao, will see more days with very heavy rainfall (daily totals exceeding 300 mm) during monsoon seasons. Meanwhile, drought periods may lengthen, even within “wet” watersheds, complicating both flood control and water supply planning.
Forest cover and ecological buffers are simultaneously under threat. The Angat watershed, for example, has shown modest but continuous tree loss (outside fire events) in recent years, per Global Forest Watch; while not yet catastrophic, such degradation erodes one of the few natural sponges left buffering floods and moderating runoff.
What does all this portend? Infrastructure designed for historical return periods (25-, 30-, even 50-year events) will increasingly be overtaken not by once-in-a-generation storms, but by annual occurrences.
Pumps will fail, drainage will overflow, and retention ponds may be overwhelmed. Unless systems are redesigned with climate projections as their foundation—incorporating greater safety margins, built‐in redundancy, more green infrastructure—each new flood season risks rendering existing investments obsolete.
What the evidence says about nature — and cost
The shift toward Nature-based Solutions (NbS) is not an ornamental trend in climate discourse; it is a recalibration of what counts as infrastructure. In the Philippine context, mangroves alone are estimated to reduce wave energy by roughly 66%, shielding more than 613,500 people and preventing billions of pesos in damage annually. Wetlands and reforested uplands add another layer of resilience: slowing peak flows, recharging aquifers, protecting fisheries, and sequestering carbon in ways that a culvert or dike cannot. These are not substitutes for engineered works, but complements that reduce pressure on them.
Financial analyses reinforce the case. A World Bank cost-benefit review of hybrid flood strategies found that mangrove belts protecting urban coastlines in Southeast Asia yield returns of up to 10:1 when avoided damages, carbon credits, and fisheries are accounted for. Similarly, an Asian Development Bank study in 2021 reported that “green-gray” projects across Asia produced stronger long-term benefit–cost ratios than conventional structures alone.
Other flood-prone countries illuminate both the promise and the politics of scaling NbS. Vietnam’s Mekong Delta has institutionalized mangrove planting alongside sea dikes; the government estimates that each hectare of mangrove forest provides storm-protection services valued at over US$1,000 per year, in addition to sustaining shrimp aquaculture. In Bangladesh, the Coastal Embankment
Improvement Project explicitly integrates tidal wetlands and natural polders with embankments, yielding reduced maintenance costs compared to “hard-only” defenses. The Netherlands, often considered the world’s flood-management laboratory, has gone further with its “Room for the River” program deliberately relocating dikes inland and restoring floodplains to give rivers back their absorptive capacity.
By comparison, the Philippine trajectory remains hesitant. Despite pilot mangrove projects in Cavite, Pampanga, and Leyte, most of the ₱545-billion flood-control program has been captured by traditional concrete-heavy projects. Here, the gap is not one of knowledge but of political will: ribbon-cuttings reward immediacy, whereas restored ecosystems demand patience, maintenance, and shared governance. Yet if evidence elsewhere is indicative, failing to mainstream NbS is not merely an ecological oversight; it is a fiscal liability that will magnify future repair bills and disaster-relief costs.
Voices from the ground and the halls of power
Local reporting in September 2025 described the small disasters that accumulated into systemic failure: stranded commuters, flooded classrooms, vendors losing a day’s income. Such accounts underline how metrics like “project completion” and “budget spent” can be poor measures of lived safety.
From the policy side, Public Works Secretary Manuel Bonoan’s testimony that Metro Manila’s drainage is “70 percent silted … it only has a carrying capacity of 30 percent” was a blunt admission that upkeep had been sidelined while new projects multiplied. Had maintenance kept pace, the new works might have had a better chance of producing lasting results.
And from the presidency, a Reuters account quoted the President saying, “There’s only one way to do it … they will not be spared,” a signal that the government acknowledges the gravity of the scandal and the need for corrective action. Whether such fire-and-forget investigations yield structural reform remains the open question.
The contrast is stark: commuters wading through waist-high water while billions in allocations are logged as “obligated”; classrooms underwater while project dashboards show rising percentages of “completed structures.” What September’s flood episodes revealed was not only hydraulic incapacity but a governance incapacity. One where measurement is decoupled from meaning, and where political theater substitutes for systemic maintenance.
The Philippines is not alone in this paradox. Jakarta, one of the world’s most flood-prone megacities, has seen repeated inundations despite massive investment in sea walls and pumping stations. A 2021 audit revealed that poorly maintained pumps and clogged drainage rendered half of the city’s system inoperative during peak rains echoing Manila’s “30 percent capacity” diagnosis. Similarly, Bangkok has grappled with costly flood-protection works that falter because canals are allowed to silt up and informal settlements obstruct natural flows. Even New Orleans, in the United States, discovered after Hurricane Katrina that decades of neglected levee maintenance magnified the storm’s devastation. A grim reminder that “infrastructure” is a verb as much as it is a noun.
These parallels matter because they strip away the illusion of Philippine exceptionalism. The common denominator is not the volume of rainfall alone, but the institutional habits that treat maintenance as expendable and project inaugurations as the real currency of politics. If Jakarta’s stalled pumps, Bangkok’s silted canals, and New Orleans’ breached levees all testify to the costs of neglect, then Manila’s September floods join a global archive of preventable disasters. The question is whether this archive will serve as a warning or as a prelude.
Toward closing the gap:
If the Philippines is to translate spending into safety, the policy mix must change:
• Audit and reorient — The ₱545 billion program, analysts argue, should be opened to transparent forensic audits, with funds shifted from underperforming projects toward climate-resilient, multi-benefit interventions.
• Adopt system-level planning — National and metropolitan drainage master plans, integrated watershed management and data-driven flood mapping will have to replace ad hoc project lists. Secretary-level admissions about the absence of a drainage blueprint should become the spur for rapid action.
• Raise design standards — Design criteria will need to shift from historical return periods to climate-adjusted scenarios looking out to 2050–2100, with independent verification required for high-value contracts.
• Invest in NbS at scale — Priority should go to restoring mangroves, rehabilitating wetlands and reforesting watersheds in areas where evidence shows the greatest benefit, combined with engineering works where they remain necessary.
• Center equity — Projects should be required to protect the most vulnerable communities first, provide fair resettlement when displacement is unavoidable and include community voices in planning.
Promises and protests
The fury of 2025: public protests, commission hearings, and the suspension of new flood projects, has created a rare political window. Voters now see in half a trillion pesos of spending the possibility of both recovery and further waste. The choice is institutional: whether the inquiry leads to reforms that close the performance gap, or becomes another episodic crisis that produces headlines but little change.
That anger is now taking physical form. On September 21, 2025, thousands are expected to gather at Luneta Park, a date chosen not only because it coincides with the anniversary of Martial Law but also because it symbolizes resistance to systemic failure. Organizers describe the rally as a convergence of urban poor groups, transport unions, students, and even middle-class homeowners—constituencies rarely aligned, but now united by the common experience of being repeatedly submerged despite record government spending. The imagery is deliberate: Luneta, historically the stage for national dissent, becoming once more a forum for demanding accountability, this time over floods that feel both perennial and preventable.
For everyday Filipinos, however, the calculus remains simple and urgent. When the next heavy rain comes, they will measure the value of public spending not in press releases or project lists, but in whether their children make it safely to school, whether their refrigerators survive, and whether their neighborhoods remain homes rather than recurring disaster sites. Until the performance gap is closed, the question “Why are we still underwater?” will remain not merely rhetorical, but painfully literal.
