Abuja Water Crisis intensifies as experts warn pollution around Mpape threatens Lower Usuma Dam and safe water supply for the capital

By Sheriff Balogun

There is a dangerous illusion at the heart of Nigeria’s capital. From the polished streets of Maitama to the diplomatic calm of Asokoro, Abuja presents itself as a city that works.

But upstream, quite literally, the foundations of that order are being eroded. And not in secret. In full view of the authorities responsible for preventing it.

Mpape, the city’s largest informal settlement, sits above the Lower Usuma Dam, the primary source of drinking water for the Federal Capital Territory.

Every rainfall carries waste, sewage and sediment downhill into that reservoir. This is not speculation.

It is documented reality. What is harder to explain is why it has been allowed to persist for decades.

The most troubling aspect of this crisis is not the contamination itself. It is the normalisation of it.

Officials have acknowledged the threat. Scientific studies have confirmed declining water quality.

Reports have described medical waste and household refuse sitting in pathways that lead directly into the dam.

Yet governance response has remained slow, fragmented and largely reactive.

The implication is stark. Abuja is attempting to purify water that is being consistently polluted at its source. That is not a sustainable system. It is an expensive illusion.

Even the numbers tell a story of strain. The Lower Usuma system was designed to deliver far more water than it currently produces.

Treatment plants operate at less than half capacity, partly because the raw water arriving at those facilities is increasingly difficult and costly to treat.

At the same time, the city’s population continues to surge, far outpacing the assumptions that guided its original design.

This mismatch between planning and reality is not unique to Abuja, but the consequences here are particularly severe. WaterAid estimates that only a small fraction of residents have access to safe tap water.

Many rely on rivers, streams or private boreholes. The latter may offer short-term relief for middle-income households, but they introduce another long-term risk: unchecked groundwater depletion.

For poorer communities, including those living around Mpape itself, there is no fallback.

Contaminated water translates directly into disease, lost income and avoidable deaths.

Cholera and typhoid are not abstract risks. They are recurring outcomes of policy failure.

And yet, policy continues to focus disproportionately on treatment rather than prevention.

Billions of naira have been committed to rehabilitating treatment plants and expanding infrastructure.

These are necessary investments, but they do not address the core issue.

A more efficient treatment plant cannot compensate indefinitely for a polluted catchment.

Filtering dirty water more effectively is not the same as protecting clean water at its source.

The events of January 2026, when water supply disruptions were linked to unpaid electricity bills, exposed another layer of fragility.

A capital city whose water system can be partially crippled by power disconnection is operating on borrowed time.

The reliance on diesel generators to sustain critical infrastructure is both costly and unsustainable.

What emerges is a pattern of governance that reacts to symptoms while neglecting causes. Mpape itself illustrates this clearly.

For years, the dominant policy instinct has been demolition. But demolition without resettlement is not a solution.

It merely displaces the problem or pauses it temporarily. The persistence of Mpape is not evidence of defiance alone.

It is evidence of unmet housing needs and unresolved historical grievances dating back to the creation of the FCT.

If Abuja is to secure its water future, it must abandon the illusion that this problem can be engineered away downstream. The solution begins upstream, with governance.

That means treating Mpape not as an anomaly to be erased, but as a community to be integrated into the city’s planning framework.

Basic sanitation infrastructure, waste management systems and drainage control are not luxuries. In this context, they are essential components of water security.

It also means enforcing environmental protections within the dam’s catchment area.

Buffer zones, erosion control and restrictions on high-risk activities such as unregulated farming are standard practices in cities that take their water sources seriously. Abuja cannot claim to be an exception.

Equally important is institutional coordination. The agencies that oversee water, urban development and environmental protection must operate with a shared mandate, not in silos.

The current fragmentation allows responsibility to diffuse, and with it, accountability.

Finally, there is the question of political will. The scale of investment already committed to water infrastructure demonstrates that resources can be mobilised when priorities are clear.

The challenge is to redirect part of that focus toward prevention, where the returns are higher and the long-term costs significantly lower.

Abuja was conceived as a symbol of national unity and modern planning.

But no city can sustain that promise without something more fundamental than architecture or administration. It needs reliable, safe water.

Right now, that foundation is under threat from a problem that is neither hidden nor inevitable. It is the result of choices, and of inaction.

The water crisis in Abuja will not announce itself dramatically when it becomes irreversible.

It will deepen gradually, quietly, until the cost of fixing it exceeds the cost of having prevented it.

That threshold is approaching. The only question is whether those in authority will act before it is crossed.
