On the morning of July 19, 2025, Mumbai woke to a sky that looked ordinary enough. By noon, the heavens had opened. In twelve hours, the city received 267 millimetres of rain—less than the infamous 944 millimetres of 2005 but enough to paralyse a metropolis of twenty million. Suburban trains stalled mid-track. Motorists abandoned cars on the Eastern Express Highway, now a canal of brown water. At Sion Hospital, junior doctors waded knee-deep to move patients to higher floors as generators sputtered. In Dharavi, families watched as sewage mixed with rainwater and crept into homes. By evening, the city that contributes six percent of India’s GDP had ground to a halt.

The official line came swiftly: “unprecedented rainfall.” The phrase was familiar, as if scripted. But to citizens, it rang hollow. This was not unprecedented. It was routine, annual, systemic. What drowned Mumbai in 2025 was not rain alone but history, neglect, corruption, and choices made by governments more interested in spectacle than survival.

A City Brought to its Knees

On the morning of July 19, 2025, Mumbai woke to a sky that looked ordinary enough. By noon, the heavens had opened. In twelve hours, the city received 267 millimetres of rain—less than the infamous 944 millimetres of 2005 but enough to paralyse a metropolis of twenty million. Suburban trains stalled mid-track. Motorists abandoned cars on the Eastern Express Highway, now a canal of brown water. At Sion Hospital, junior doctors waded knee-deep to move patients to higher floors as generators sputtered. In Dharavi, families watched as sewage mixed with rainwater and crept into homes. By evening, the city that contributes six percent of India’s GDP had ground to a halt.

The official line came swiftly: “unprecedented rainfall.” The phrase was familiar, as if scripted. But to citizens, it rang hollow. This was not unprecedented. It was routine, annual, systemic. What drowned Mumbai in 2025 was not rain alone but history, neglect, corruption, and choices made by governments more interested in spectacle than survival.

Colonial Drains for a Postcolonial Metropolis

The roots of Mumbai’s floods lie in its colonial foundation. The first underground storm-water drains were built in the 1860s, designed to handle 25 millimetres of rainfall per hour. At the time, the figure was generous. But the drains were never expanded to match the city’s explosive growth. A century and a half later, the same system still forms Mumbai’s circulatory core, clogged and undersized, forced to handle rain intensities four to five times higher than its design capacity.

As the city grew, its geography was remade. Marshes and wetlands that once absorbed water were filled in to build offices and apartments. The Mithi River, which once carried monsoon flows to the sea, was narrowed into a drain. Mangroves were hacked down for reclamation. Each act of development was also an act of dismantling natural infrastructure. The British left Mumbai with an inadequate system. Independent India, instead of correcting it, layered neglect atop legacy.

2005: The Warning Ignored

On July 26, 2005, the city received 944 millimetres of rainfall in a single day—the eighth-heaviest 24-hour rainfall ever recorded worldwide. More than 400 people died. Trains stopped, buses floated like carcasses, and power went dark for 36 hours. An estimated ₹20,000 crore vanished in economic losses, much of it uninsured.

The human toll was searing. Children drowned in basement schools. Commuters spent nights trapped in stalled trains. Families searching for loved ones found only bodies in morgues. The floods also unmasked the consequences of ecological destruction: the Mithi, choked with debris and narrowed by encroachments, spilled over violently.

The disaster was supposed to be a turning point. Politicians promised reform, engineers demanded modernisation, and citizens, still soaked in grief, believed change would come. The BRIMSTOWAD project was born.

BRIMSTOWAD: The Fiasco That Keeps Drowning Mumbai

BRIMSTOWAD—the Brihanmumbai Storm Water Disposal Project—was announced as Mumbai’s salvation. Its mandate: upgrade drains to handle 50 mm/hr, double the colonial standard, and prevent a repeat of 2005. The plan involved widening nullahs, building pumping stations, and installing tidal gates. In 2006, the cost was set at ₹1,200 crore, with funds promised under the Jawaharlal Nehru National Urban Renewal Mission. The timeline: six years.

Instead, two decades later, the project remains unfinished. By 2015, costs had swollen to ₹3,884 crore. Pumping stations were delayed by contractor disputes. Tidal gates were postponed. The Mithi’s rejuvenation stalled in bureaucratic turf wars. Contractors dredged nullahs on paper while muck slid back in after token removal. Whistle-blowers described desilting scams where the city paid for silt to be moved only metres away. The Comptroller and Auditor General flagged persistent delays and cost overruns. Nothing changed.

In 2017, floods again paralysed the city, exposing the uselessness of half-built pumping stations. In 2019, the same. In 2025, despite two decades of promises, BRIMSTOWAD was still a punchline—a word citizens muttered bitterly each July while bailing out their homes.

The project’s collapse is not technical but political. Drains lack the visibility of flyovers or statues. A pumping station hidden behind a wall does not win elections. So year after year, the city spends billions on spectacle while survival is postponed.

The Double Tax of Living in Mumbai

For residents, the cost of this neglect is a cruel arithmetic. Mumbai is one of the most expensive cities in the country. Apartments in suburbs like Andheri or Chembur cost upwards of ₹1.5 crore. Rentals consume nearly half of middle-class incomes. Slum dwellers pay too, in rents and extortion fees to stay in precarious shacks.

Taxes are heavy: Mumbai contributes nearly a third of India’s direct tax collection and a significant share of GST. It finances the Union. And yet, each monsoon, it pays again in hidden levies: ruined furniture, lost wages, destroyed vehicles, hospital bills. An IIT Bombay study estimated that a single day of transport paralysis costs ₹300 crore in lost productivity. For the poor, the loss of three days’ wages can mean eviction.

This is the double tax of Mumbai. Citizens pay in rupees to the exchequer and in blood, sweat, and illness to the floods. The rich insure; the poor borrow. Resilience is celebrated, but what is called resilience is actually resignation. People do not triumph over water—they survive it silently because they have no alternative.

The Human Body in Floodwater

The true costs of floods are not only financial but biological. Floodwater in Mumbai is sewage, industrial waste, and rat urine stirred into a toxic broth. When citizens wade through it, their bodies absorb the bill.

Leptospirosis—transmitted through rat urine—spikes after every flood. In 2005, more than 200 died of the disease. In 2017 and 2019, hundreds more fell ill. Cholera and dysentery spread as pipelines crack under flood pressure. Dengue and malaria rise in stagnant pools that linger long after rains cease.

Hospitals collapse under the strain. Public hospitals with 25,000 beds for 20 million residents operate beyond capacity. During the 2025 floods, Sion Hospital saw patients lying on floors as nurses waded through ankle-deep water to administer drips. Oxygen ran out. In private hospitals, ambulances could not reach through flooded streets.

Beyond disease lies trauma. Studies after the 2005 flood found post-traumatic stress in children who still fear heavy rain years later. Yet mental health receives no investment. Each year, the biological tax is paid in fever, in dehydration, in debt after medical bills. Floods in Mumbai enter through the skin, the stomach, the mind.

Prestige Politics vs Prevention

While drains rot, billions are poured into spectacle. The Coastal Road, a ₹12,700 crore project built for elite motorists, slices into the Arabian Sea, reclaiming land that once absorbed tidal surges. Scientists warn it worsens flooding by blocking drainage. Still, it advances.

In 2018, Maharashtra announced a ₹3,000 crore statue of Chhatrapati Shivaji Maharaj rising from the sea. Its scale dwarfs the budgets for hospitals in flood zones. Metro projects, necessary but poorly planned, have cut through forests and wetlands, worsening local waterlogging.

These choices are deliberate. Politicians prefer projects that can be televised, inaugurated, and glorified. A statue is visible. A drain is not. Mega-contracts tied to prestige projects generate rents and kickbacks; desilting drains does not. Spectacle has replaced survival as the organising logic of governance.

Exporting Neglect: The Mauritius Paradox

The paradox deepens when India’s foreign aid enters the frame. In Mauritius, India financed the Metro Express—USD 190 million in 2017, plus USD 300 million in 2022. At least 30% of contracts were awarded to Indian firms. In Delhi, it was marketed as solidarity; in Port Louis, ribbon-cuttings praised friendship.

On the ground, citizens of Quatre Bornes and St. Jean saw something else: floods surging into homes after heavy rain, water channelled by the metro’s elevated viaducts. In January 2023, human remains from a cemetery washed into living rooms. Officials blamed “exceptional rainfall.” The phrase was identical to Mumbai’s script.

In 2025, India pledged 100 kilometres of water pipelines for Mauritius, even as drains in Mumbai remained unfinished. The irony was colonial. Mauritius was once ruled from India; now Indian taxpayers finance prestige abroad while their own financial capital drowns. Neglect is not only domestic—it is exported.

Climate Futures

Even without corruption and spectacle, Mumbai faces a planetary crisis. Sea levels are rising between 0.28 and 1.1 metres this century. Large parts of the city—Nariman Point, Bandra-Kurla Complex, Versova—sit barely a metre above current sea level. By 2050, maps of the city show semi-submersion.

Rainfall patterns are shifting. Short-duration, high-intensity cloudbursts are more frequent. Between 2014 and 2024, the city experienced 28 extreme rainfall events within hours. Each one overwhelmed a system still designed for colonial rain.

The city’s ecology, once protective, has been dismantled. Mangroves have been cut by nearly 40% since 1990. Wetlands turned into offices. Reclamation treated as progress. But what progress means, in practice, is flood.

Other cities chose resilience: London built the Thames Barrier; New York launched the Big U; Singapore built the Marina Barrage. Mumbai built statues. Its choice is not technical impossibility but political refusal.

Solutions and Accountability

The solutions are banal in their obviousness: complete BRIMSTOWAD, restore mangroves, resurrect wetlands, establish a resilience fund, flood-proof hospitals, and create a single flood management authority. Each has been proposed. None has been prioritised.

Money is not the problem. The ₹3,884 crore needed to finish BRIMSTOWAD is dwarfed by the ₹12,700 crore already spent on the Coastal Road. A resilience fund could be financed by levies on developers whose projects increase flood risk. Mangroves could be restored at a fraction of the cost of annual flood damage.

What is absent is accountability. Contractors default with impunity. Politicians shift blame to “exceptional rain.” Media fetishises resilience instead of demanding responsibility. Citizens, resigned, accept floods as fate.

But they are not fate. Floods are choices, inscribed in budgets and contracts. To restore ecology, to invest in prevention, to demand accountability is not utopian—it is survival.

Conclusion: Acts of Neglect

The flood of 2025 was not unprecedented. It was foretold. It was rehearsed in 2005, repeated in 2017, replayed in 2019 and 2021, and delivered again in 2025. Each time, the water carried not only debris but evidence of political failure.

Drains remain colonial. BRIMSTOWAD remains incomplete. Citizens pay a double tax. Their bodies absorb disease. Their children inherit trauma. Their government builds roads into the sea and statues above the harbour while leaving the city to drown. Abroad, India builds metros and pipelines, exporting the same neglect that drowns its own.

The seas rise. The rains intensify. The city waits. And each July, when the waters come, citizens wade, endure, and remember that survival here is taxed twice—by the state, and by its abdication.

Mumbai’s floods are not acts of God, but acts of neglect.
