Health and Sanitation Challenges in Colonial India's Divided Cities

In a colonial Indian city, the quality of the air you breathed, the water you drank, and the drains that carried away your waste depended largely on one thing: which side of the city you lived on. The “White Town” of European officials and the “Black Town” of Indian residents were not just socially separate but physically engineered to be unequal. Roads, sewers, water pipes, and hospitals followed the colour line. This divided geography shaped who got sick, who survived epidemics, and whose neighbourhoods were blamed when disease struck. Understanding health and sanitation in these divided cities reveals how colonial rule built inequality directly into the urban landscape, leaving legacies that many Indian cities still grapple with today.

How colonial public health policy drew the colour line

British public health in India did not begin as a project to protect everyone. It began as a project to protect the rulers. For much of the nineteenth century, sanitary effort was aimed at keeping British soldiers and administrators alive in a climate they considered hostile and dangerous.

The colonial regime concentrated on protecting troops and officials from tropical disease, which led to military hospitals and medical services in urban centres while the rural majority remained underserved. The same logic operated within cities. The European quarter received the investment; the densely populated Indian quarter was left to manage with far less.

Two cities in one

The physical contrast was stark. In presidency towns like Calcutta (now Kolkata), Bombay (now Mumbai), and Madras (now Chennai), European quarters featured wider streets, better drainage, and piped water supply while “native quarters” received minimal attention. Water systems were built primarily for European residential areas, and Indian neighbourhoods were left dependent on traditional wells and tanks. This was not an accident of uneven growth. It reflected a clear order of priorities in which the comfort and safety of the colonial elite came first.

Historians describe the underlying logic as one of protection. Public health was driven by the need to shield the elite, and a major aim of sanitary measures across colonial India was to control the spread of epidemics from fairs, bazaars, and pilgrimage centres into European-inhabited zones. In other words, the goal was less to make the whole city healthy and more to build a sanitary buffer around the rulers.

Epidemics and the logic of urban segregation

Nothing exposed and hardened the city’s divisions more sharply than epidemic disease. When cholera and plague struck, colonial authorities frequently traced the danger to the Indian quarter, treating “native” neighbourhoods and their residents as the source of contagion. This framing turned a public health crisis into a justification for segregation.

Cholera and the “native” quarters of Calcutta

Calcutta offers a clear example of how unequal infrastructure shaped who fell ill. The city sat on swampy ground, and its civic authorities spent decades debating drainage and water supply. While a centralized sewage system was introduced in 1865 and a filtered water supply in 1869, the benefits were uneven. As the administration focused its funds and energy on sewage, Calcutta saw repeated cholera outbreaks, particularly among residents of the “native” quarters of north Calcutta, including one episode in 1865 that killed more than two hundred people.

The improvements that eventually arrived did reduce disease. After clean piped water reached the city, a centralized sewage system and filtered water supply led to a notable decline in cholera. Yet for a long time these gains were concentrated in the better-served parts of the city, while fringe and densely Indian areas continued to wait. The lesson colonial reformers drew was rarely about equal access. As one study of Calcutta notes, sanitary reformers often framed their work as a mission to civilise “backward” and “unclean” natives rather than simply to deliver services everyone deserved.

Plague and the assault on the Indian neighbourhood

The bubonic plague that reached Bombay in 1896 pushed the segregationist logic to its extreme. The first case was detected that September, and the disease spread with terrifying speed. By March 1897, municipal authorities estimated around 20,000 people had died, and roughly half the population had fled the city. The epidemic was part of the wider Third Plague Pandemic moving along global trade routes, and Bombay, as a crowded port, was acutely vulnerable.

The colonial response treated the Indian quarter as both the problem and the target. Plague committees were given sweeping powers, and the measures they imposed fell most heavily on Indian residents. Control efforts included compulsory hospitalization and segregation of plague “suspects,” forced entry into homes, and the destruction of buildings labelled unfit for human habitation. House-to-house searches were carried out by European soldiers and sanitary inspectors who often disregarded privacy and religious custom.

These intrusions provoked deep anger. Forced entry into homes, the segregation of men and women, and disregard for religious sensibilities led to widespread hostility, and in Pune the resentment culminated in the assassination of the British plague commissioner W. C. Rand in 1897. Many families went so far as to hide the sick, fearing relatives would be taken to segregation camps and die alone without proper funerary rites. The point is not only that the measures were harsh, but that they were directed at Indian bodies and Indian neighbourhoods in a way the European quarter never experienced.

When disease became a metaphor

This pattern was not unique to India. Across the British Empire, colonial officials used the language of disease to justify keeping populations apart. In colonial Nairobi, for example, settlers dominating the public health committee ensured their own neighbourhoods received municipal services while rationalising segregation by casting Africans as carriers of disease. Scholars have called this the “sanitation syndrome”: the use of hygiene as a respectable cover for racial separation. Seeing the same logic repeated from Bombay to Nairobi makes clear that sanitary segregation was a tool of colonial governance, not a neutral medical necessity.

Municipal inefficiency, bias, and persistent disparity

Behind the dramatic epidemics lay a quieter, structural problem: how municipal money was raised and spent. Colonial municipal bodies were often underpowered, unevenly funded, and shaped by the interests of those who controlled them. The result was a built environment that entrenched health inequality long after any single outbreak had passed.

Who controlled the municipal purse

Municipal commissions were established in the presidency towns during the 1850s and 1860s, but these bodies had limited jurisdiction and effectiveness. Where settler or European interests dominated civic committees, spending naturally flowed toward their own districts. The pattern visible in Nairobi, where the settler community used its grip on the public health committee to channel infrastructure to European areas, reflected a broader colonial tendency to align municipal investment with the priorities of the ruling minority.

Even well-intentioned engineering decisions could deepen the divide. In Calcutta, civic authorities sanctioned funds to purify drinking water but then let the project stall while they poured resources into an elaborate sewage system, leaving water purification to take a back seat for years. Decisions about sequencing and priority repeatedly favoured certain functions and certain areas, and the people who waited longest for clean water and working drains were overwhelmingly in the Indian quarters.

The slow and uneven reach of reform

Reform did eventually expand. After 1912, the colonial administration began pairing local offices with central health officers and funding sanitation projects more widely, and over the following decades it invested in waterworks and drainage across Bengal’s towns. By 1931, forty-one water supply systems had been completed, supplying over 15 million gallons of clean water a day on average. These were real improvements that saved lives.

Yet the expansion was gradual and incomplete, and it arrived only after decades during which Indian neighbourhoods bore the heaviest disease burden. The improvements also tended to follow the established hierarchy, with sanitation conceived relationally and a clear hierarchy maintained between the imperial centre and the colony even in technical debates about something as basic as drainage. Sanitation reform, in other words, did not erase the colour line; it largely worked within it.

A debate that recognised the real cause

It is worth noting that not every colonial expert endorsed segregation as the answer. By the early twentieth century, official inquiries increasingly acknowledged that poor health among Indians was driven by poor sanitation and malnutrition, with some recognising that segregation might not be fruitful in India. This admission mattered. It showed that the disparities were not the inevitable product of an Indian “nature,” as racial theories claimed, but the predictable outcome of how cities were planned, funded, and governed. Where infrastructure followed, health followed; where it was withheld, disease persisted.

The legacies that outlived the Raj

The divided sanitary city did not vanish in 1947. The clustering of disease, the unequal reach of piped water and drainage, and the neighbourhoods historically denied investment left patterns that newer municipal systems inherited. Many Indian cities still experience monsoon waterlogging concentrated in older, denser localities that were neglected under colonial planning, a direct echo of decisions made more than a century ago. Recognising this history helps explain why sanitation and water access remain such central concerns in Indian urban policy, from the expansion of municipal water networks to large-scale campaigns for safe sanitation. The work of undoing a divided city is, in many ways, still underway.

The deeper takeaway is that “health” in the colonial city was never a purely medical matter. It was a question of power, geography, and money. Who lived where, who controlled the budget, and whose body counted as worth protecting determined who breathed clean air and who died in an epidemic. That is a useful lens for examining urban inequality in any era, including our own.

What do you think? If colonial cities engineered inequality through where they placed pipes, drains, and hospitals, how much of today’s urban health gap is shaped by similar choices about infrastructure rather than by individual behaviour? And when an epidemic strikes a modern city, who gets blamed, and who actually bears the greatest risk?
