Fact-Check 22 – Flood Mitigation Progress

By Prof. MarkAnthony Nze

The Great Drainage Delusion

Between 2023 and 2025, Governor Hope Uzodinma has made one promise so often it might as well be inscribed on Imo’s coat of arms: “All flood-control projects across Imo State have been completed.”
At a well-choreographed 2024 press briefing inside the Government House, he went further, declaring the state’s drainage network “a lasting solution to decades of flooding in the capital.”
State-run media quickly fell in line, serenading the public with headlines hailing a “triumph of engineering and governance.”

But outside the air-conditioned conference halls, the evidence has a different texture—wet, brown, and ankle-deep.
Sometimes, when the rains are generous, it climbs to the knees.

For residents of Owerri, Oguta, and Ohaji-Egbema, the so-called “lasting solution” has lasted only as long as a dry day. The city’s gutters, where “innovation in infrastructure” supposedly meets “visionary leadership,” are less a testament to engineering than to the enduring resilience of ordinary people wading home through liquid irony.

Behind the governor’s glowing rhetoric lies a city drowning—quite literally—in its own contradictions.
The only thing that seems to flow freely in Uzodinma’s flood-control miracle is the propaganda.

The Data Reality: When Water Refuses to Lie

The Nigeria Hydrological Services Agency (NIHSA) Annual Flood Outlook 2024 paints a troubling picture: Imo remains among the 13 high-risk flood states in the federation. Satellite flood-mapping conducted in June 2024 shows recurrent inundation zones along Egbu, World Bank, and Relief Market corridors—areas supposedly “fixed” under the Urban Flood Mitigation Programme.

Further, CoST Nigeria’s Infrastructure Data Portal (2025) lists four major flood-control contracts in Imo—Otamiri River Channelization, Nekede-Umuguma Drainage Network, Naze Flood Diversion, and Wethedral Road Drainage Expansion. Of these, only one—the Naze project—has reached full completion status. Two are still classified as “stalled,” while the Otamiri channelization, awarded since 2021, remains just 48 percent executed as of May 2025.

The Federal Ministry of Water Resources Flood Status Report (2024) corroborates this, ranking Imo’s urban flood-preparedness capacity at 39 percent, well below the national median of 54 percent.

In short, the floods are not finished—and neither are the projects.

The Anatomy of Incompletion

A closer inspection of the supposed “completed” flood projects reveals a series of patterns emblematic of subnational mismanagement: poor design, inadequate funding, weak supervision, and political haste.

Residents of Egbu Road recall bulldozers that arrived with cameras but left before construction reached the main drain junction. At Relief Market, drainage channels designed to feed into the Otamiri River were left unconnected, turning access roads into open cesspools. In Orlu and Mbaise, contractors abandoned sites for months, citing unpaid mobilization fees.

According to field data compiled by IMOSEMA’s 2025 Flood Impact Assessment Report, 71 communities across seven LGAs experienced at least one significant flood incident in the 2024 rainy season. More than 12,000 residents were displaced, with property losses estimated at ₦2.8 billion.

If “all flood-control projects” were truly completed, such devastation would not be recurring with this frequency and scale.

The Fiscal Footprint: Where the Money Flows but Water Doesn’t

The BudgIT Foundation’s Fiscal Transparency Review (2025) shows Imo allocated ₦18.4 billion to “Flood and Erosion Control” between 2020 and 2024. However, only ₦9.7 billion was traceable to completed physical projects. The rest is marked as “ongoing,” “unverified,” or “administrative costs.”

A deeper audit reveals procurement irregularities: multiple projects awarded under “emergency procedures” without open tendering, contracts re-awarded under new company names, and discrepancies between contract sums and visible execution levels.

The CoST Nigeria Disclosure Portal (2025) lists identical project descriptions under different contractors—an indicator of duplication designed to inflate expenditure records.

In other words, the money has moved faster than the water.

Owerri: A Capital Sinking Under Promises

A drone survey conducted by the World Bank’s Urban Resilience Program (2024) shows that drainage coverage in Owerri increased by only 2.3 percent between 2019 and 2024. Meanwhile, urban expansion surged by nearly 7 percent during the same period. The imbalance means new developments have outpaced the capacity of stormwater infrastructure to manage runoff.

The result: predictable disaster.

During the August 2024 downpour, Wethedral, Douglas, and Port Harcourt roads turned into channels of brown water, submerging shops and vehicles. The Imo State Emergency Management Agency recorded 56 major flood incidents within Owerri Municipal alone in that year—more than double the incidents recorded in 2021.

For residents, the government’s claim of completion sounds less like a report of progress and more like a cruel irony. “Every rainy season, we are forced to rebuild,” says Mrs. Ada Eze, a shop owner at Relief Market. “If this is completion, then maybe water has a different definition in Government House.”

The Environmental Cost: Neglect Meets Climate Change

Imo’s flood crisis is no longer just a matter of infrastructure—it’s an environmental emergency.
The Nigeria Hydrological Services Agency (2024) identifies the Otamiri, Nworie, and Oramiriukwa rivers as major overflow zones exacerbated by urban encroachment and waste dumping. The absence of waste management amplifies runoff blockage, transforming drainage systems into open sewers.

The World Bank’s Climate Adaptation Report (2024) notes that Imo’s flood-resilience investments remain “disproportionately focused on short-term civil works, with minimal integration of environmental restoration.” Put simply, the state builds drains but neglects to preserve wetlands and buffer zones that absorb water naturally.

This mechanical approach to hydrology—treating flooding as a construction problem rather than an ecosystem imbalance—has doomed even the few completed projects to rapid failure.

Transparency Gap: Projects Without Public Proof

Another glaring red flag is opacity.
Despite state announcements of “full completion,” neither the Ministry of Works nor the Ministry of Environment has uploaded final project completion reports to the CoST Nigeria Open Contracting portal. No detailed cost breakdowns, no geo-tagged completion photos, no performance audits.

The Imo Open Budget Portal, inactive since late 2023, contains no updated records of capital expenditure for flood mitigation. The absence of data itself has become evidence of evasion.

Lives in the Balance

Flooding in Imo is not a political abstraction—it is a humanitarian crisis. Every year, homes collapse in Orlu, farmlands wash away in Ohaji, and students wade through rising waters to reach classrooms in Owerri.
The 2024 floods displaced nearly 15,000 residents, mostly in low-lying areas, according to the Imo SEMA Annual Emergency Report.

Behind these numbers are faces: children missing school, traders losing capital, and communities rebuilding from scratch after each storm. The gap between political claim and lived reality is measured not in statistics but in survival.

Verdict: The Flood That Won’t Recede

Governor Uzodinma’s declaration that “all flood-control projects are completed” is false. Verified data from NIHSA, CoST Nigeria, and the World Bank’s resilience program contradict the claim on every metric—completion rate, functionality, and effectiveness.

The projects remain fragmented, underfunded, and poorly maintained. The supposed triumph of infrastructure is, in truth, a mirage of publicity—another instance where political narration has replaced technical accountability.

In a state where erosion and flooding have become seasonal afflictions, completion cannot be claimed until drains carry water efficiently and citizens live without fear of the next rainfall.

For now, the evidence is unambiguous: Imo’s flood-control strategy is still under construction—both literally and institutionally.

Interpretation

Over a five-year period, Imo’s flood-vulnerable LGAs rose from 8 to 13, a 62 percent increase. This expansion shows that new urban settlements are being built faster than protective infrastructure can accommodate them.

The Owerri urban belt, now the most densely populated zone in the state, sits on a naturally low-lying floodplain fed by the Otamiri and Nworie Rivers. Despite repeated government claims of “comprehensive flood control,” the risk map has expanded—proof that drainage works are fragmented or incomplete.

Population at risk has climbed steadily, from about 314,000 in 2020 to over 450,000 in 2025, according to NIHSA’s hazard-exposure modelling. These aren’t abstract figures; they represent people who lose homes, property, and income with every rainy season.

In essence, while political rhetoric portrays completion, hydrological data confirms expansion of danger, not its containment.

Interpretation

Out of five major projects tracked, only one—Naze Flood Diversion—reached full completion.
The rest linger between 31 and 67 percent completion. When averaged, Imo’s flood-mitigation works show just about 60 percent physical progress, contradicting the government’s 100 percent completion claim.

The Otamiri River Channelization project is the cornerstone of Owerri’s drainage system. Yet, at less than half executed four years after contract award, it remains the biggest bottleneck. Without that main outfall, secondary drains like those along Egbu and Relief Market have nowhere to discharge runoff, making them cosmetic rather than functional.

A pattern of “emergency awards” recurs across several projects—an administrative shortcut that often bypasses competitive bidding and independent verification. This reflects not only inefficiency but systemic opacity in procurement, where speed is prioritized for headlines, not for hydrological coherence.

Table 3: Fiscal Allocations vs. Physical Completion (₦ billion)

Source: BudgIT Fiscal Transparency 2025; Imo Budget Office; World Bank Resilience Data

Interpretation

From 2020 to 2024, Imo increased its flood-control budget by 205 percent—from ₦2.1 billion to ₦6.4 billion. Yet verified project execution improved only marginally.

Less than 60 percent of funds released translate into physical infrastructure, exposing a classic gap between fiscal motion and material outcome. Audit trails show that portions of “flood control” spending are re-classified as “urban beautification” or “administrative costs,” categories that absorb funds without measurable hydrological value.

BudgIT’s 2025 audit flags several contracts as “multi-year re-entries”—projects repeatedly re-budgeted under new fiscal labels to simulate progress. The implication is structural: Imo’s flood problem is not under-financing, but under-delivery.

Money moves; water doesn’t.

Table 4: Projected Flood Risk and Infrastructure Coverage (2025 – 2030)

Source: World Bank Urban Resilience Model; NIHSA Forecast 2025; Imo SEMA Projection Unit

Interpretation

This projection—based on hydrological simulations and World Bank resilience parameters—shows two stark possibilities.
If drainage coverage continues to expand slowly (≈ 4 percent per year), Owerri will still record over 50 flood events annually by 2026. Economic losses will exceed ₦ 2.5 billion each year, mostly borne by small businesses and low-income residents.

However, with accelerated infrastructure completion and proactive maintenance, drainage coverage could reach 58 percent by 2030. That would cut flood frequency by nearly half and lower annual damages to ₦ 1.5 billion.

The data therefore reveal a window of opportunity: within five years, a 25-point increase in coverage can translate into a 46 percent reduction in flood losses—if governance matches design.

The rainfall trajectory further complicates this equation. Meteorological models predict a steady rise in mean annual rainfall (from 2,140 to 2,370 mm), a trend linked to global climate shifts. Without adaptive drainage expansion, even well-built systems could be overwhelmed by higher storm intensity.

Synthesis: What the Four Tables Reveal

Taken together, these datasets trace the anatomy of Imo’s flood-management crisis:

1. Rising Risk (Table 1):More localities are exposed to flooding each year, showing that new drains have not offset the pace of urban sprawl.
2. Partial Progress (Table 2):Projects stall at mid-execution, creating a patchwork of half-finished defences that fail as a system.
3. Fiscal Disconnect (Table 3):Spending increases without proportional results, pointing to weak oversight and political overstatement.
4. Predictive Urgency (Table 4):If trends persist, economic losses and displacement will worsen through 2030; only sustained capital commitment and ecological planning can reverse the curve.

The evidence transforms the governor’s blanket claim of “completion” into a measurable falsehood.
Data from federal agencies, international partners, and local monitoring units align on one truth: Imo’s flood-control effort remains incomplete, under-performing, and dangerously behind schedule.
