From Cesspool to Sewer—Technological Advance or Epistemic Reification?
When we think of modern urban life, we often take for granted the hidden systems that support it: clean water, efficient waste disposal, and sprawling infrastructure. Yet beneath the city lies a complex story not just of engineering achievement, but of evolving ways of thinking about humanity and our place in the natural world. The transformation “from cesspool to sewer” is one such story—a narrative that reveals as much about the human mind as it does about pipes and drains.
More Than Just Pipes: Sewers as Epistemological Symbols
The phrase “from cesspool to sewer,” borrowed from scholars M. Allen and F.W. Geels, seems at first a simple shorthand for technological progress. In the Netherlands, as Geels describes, this shift marked an epidemiological breakthrough: local governments dredged canals, installed public toilets, and prioritized sanitation, contributing to declining death rates from waterborne diseases. But to stop at the technological would miss the deeper implications of this transformation.
This blog post argues that the transition from cesspool to sewer was not merely a practical development—it was a reification of the Modern episteme, the dominant way of understanding the world that centers the human subject and promotes urban, scientific rationality.
A Shift in Thinking, Not Just in Technology
While Geels frames this transition in terms of socio-technical systems (STS) and regime transformation, a closer look suggests something else: that the move to sewers marks a consolidation of the Modern worldview. In this episteme, urban life is increasingly prioritized, and the focus shifts from humanity’s embeddedness in nature to humanity’s domination over it.
The cesspool, a remnant of what might be called the Classical episteme, was localized and manually managed. The sewer, by contrast, is systemic, expansive, and invisible—a perfect metaphor for the Modern desire to control and sanitize the environment while distancing ourselves from the unpleasant byproducts of our own existence.
Sewerage as a Mirror of Modernity
The sewer system, then, isn’t just a technical achievement. It’s a symbol of modern epistemic commitments: the belief in rational planning, the separation of humans from nature, and the idea that problems can be solved by making them disappear—often by sending them “away.” In many cities, including Halifax, this meant piping sewage directly into harbors and oceans, with little thought given to long-term environmental consequences.
This practice wasn’t rooted in scientific confidence that nature could absorb our waste. Instead, it reflected a cultural invisibility—a refusal to acknowledge pollution unless it posed an immediate, visible threat. As long as the harbour looked clean, it was deemed safe. This perception was reinforced by economic calculations that externalized environmental costs, making water-based waste disposal appear efficient and logical.
The Loss of Waste as Resource
Historically, waste was understood as a potential resource. Composting, fertilizing, and reusing waste were common practices before the rise of the Modern episteme. But as cities grew and modern infrastructure developed, waste lost its perceived value. Scholar Sabine Barles observes that waste was increasingly seen as “worthless,” leading to its externalization and discharge into rivers and harbors.
This shift marks a profound epistemic transformation—one where nature becomes a backdrop, not a partner. The natural world is no longer seen as intertwined with human life but as something to be managed, or worse, exploited.
A Paradigm That Persists
The sewer system continues to reflect the core paradoxes of Modernity. On one hand, it embodies progress: reduced disease, cleaner streets, and increased public health. On the other, it reinforces a mindset that separates humans from nature and allows for the continued degradation of ecosystems under the guise of cleanliness.
This legacy is especially visible in the case of Halifax Harbour, where the disappearance of sewage into the sea masked the long-term ecological damage. The absence of public discourse or scientific literature on the harbour’s condition during the late nineteenth and early twentieth centuries is telling. Pollution remained out of sight, and thus, out of mind.
Conclusion: Rethinking Progress
Understanding sewer systems as products of an epistemic regime—not just technological artifacts—forces us to rethink what counts as “progress.” While sanitation infrastructure has undoubtedly saved lives, it has also entrenched ways of thinking that separate humans from the natural systems we depend on.
The lesson here is not to reject technology, but to question the assumptions behind it. As we face new environmental crises, from climate change to ocean acidification, we must ask: Are our solutions reinforcing outdated paradigms? Or can we imagine new epistemes—new ways of knowing—that reconnect us with the natural world, even as we continue to build our cities?
