“bundled, buried, and behind closed doors”

[“Bundled, Buried, and Behind Closed Doors”, a documentary short by Ben Mendelsohn and Alex Chohlas-Wood, looks at one of our favorite things — the physical infrastructure of the internet — and, in particular, the telco hotel at 60 Hudson Street. It’s particularly fascinating to see how 60 Hudson Street exhibits the “tendency of communications infrastructure to retrofit pre-existing networks to suit the needs of new technologies”: the building became a modern internet hub primarily because it was already a hub in earlier communications networks, permeated by pneumatic tubes, telegraph cables, and telephone lines, and thus easily suited to the running of fiber-optic cables. (This is important because it demonstrates the relative fixity of infrastructural geographies — like the pattern of the cities they are embedded in, the positions of infrastructures tend to endure even as the infrastructures themselves decay and are replaced.)]

[“Squirrel Highways”, a drawing by Denis Wood, Carter Crawford and Shaub Dunkley, from Denis Wood’s Everything Sings: Maps for a Narrative Atlas, which Wood describes as a “cartographic poem” about the North Carolina neighborhood of Boylan Heights, where he lives.  Wood evidences a fantastic ability to animate prosaic terrain through the making of maps which are simple in conception,  deliberate in execution, and, I think, derive their power from the splendid isolation that they render each element of that terrain in — power poles and power lines, traffic control signs, delivery routes, bus routes as choreography akin to ballet, etc.

soft landscapes

This week, I’ve organized a short (very short) lecture series for the students in my studio (well, the “Post-Natural Ecologies” half of the studio) at Virginia Tech’s Washington-Alexandria Architecture Center.

Tuesday at 5:15, Fred Scharmen (sevensixfive/the Working Group on Adaptive Systems) will give a talk entitled “Soft Sites”, examining four sites on the Middle Branch of the Patapsco River, which are “all located at the intersections of infrastructure, industry, and commerce”.  Though these sites are seemingly “castoffs”, Fred argues that “closer examination reveals a more complicated reality – [they] are in fact mirrors of their surroundings, visible evidence of the shifting political, economic, environmental and cultural interests that compete to determine the creation of new space and development”.

Friday at 4:00, Brett Milligan (Free Association Design) will speak on “Landscapes of Dredge: Cycles and Choreography”, looking at the industrial act of dredging as a component of a wider system of anthropogenically-accelerated sediment handling processes which generate a fascinating array of diverse and bizarre landscapes.  (Brett is based in Portland, Oregon, and will be joining us via the internet.)

While this is rather late notice, both of the lectures are free, so if you’re in the DC area either tomorrow (Tuesday 25 October) or Friday (28 October), feel free to stop by — as the poster above says, we’ll be in the Red Room of the WAAC (1001 Prince Street).

auckland volcanic field

Above and below, snapshots from “Auckland Volcanoes”, a map by Carl Douglas.

Carl’s map marks the location of each of the volcanic craters that dot the surface of Auckland.  The craters exhibit a fascinating variety: some have been heavily altered by mining operations (which particularly seek volcanic scoria, a type of rock suitable for use in landscaping and drainage construction); others have been “subsumed by suburbia”, as Carl puts it; still others are wholly or nearly wholly intact, protected by the 1915 “Reserves and Other Lands Disposal and Public Bodies Empowering Act” and their own insuitability for development.

A while ago, I wrote a post called “recreational volcanism”, about the possibility that there might be a

…city [which], being built atop dormant volcanoes, has reserved the most unstable districts of the city as municipal parks.  Whose landscape architects have been called upon to design access systems for these geological freakologies, these unstable geysers, mud pots, fumaroles, and hot springs which sit between broad avenues, kvartals, dense clusters of towering buildings, and whose citizens frequent its public parks not for bucolic relaxation but for sublime thrills.

Auckland isn’t quite that city; but, perched atop its still-active volcanic field, it’s the closest thing I’ve seen.

on blogging architecture

Geoff Manaugh contributes a series to Arbitare that looks at the history, equipment, content, audience, and future of architecture blogging.  Being “someone who has founded his entire present career through blogging”, Geoff obviously both brings serious qualifications and an innate (and admitted) bias to the topic; the resulting personal perspective of the series only serves to make it more interesting.

road ecologies

A nice slideshow by Laura Tepper on Places looks at the intersection of “wildlife habitat and highway design”, from “the six massive wildlife overpasses lining the Trans-Canada Highway in Banff National Park” to HNTB and Michael Van Valkenburgh’s winning entry to the recent ARC competition for Vail Pass, “Hypar-nature” (pictured above) and across the Atlantic to the long history of animal road crossings in France and comprehensive national highway landscape plans in the Netherlands.

unconventional intersections

At Slate, Tom Vanderbilt writes about the design of intersections to eliminate left-turns, which historically produced such oddities as the Jersey jughandle and the Michigan left, as well as more recent innovations like the diverging diamond interchange and continuous flow intersection.

quilian riano interviews chris reed

Quilian Riano interviews Chris Reed (Stoss Landscape Urbanism) for Places; the interview touches on a broad range of topics, including Stoss’s recent work, the importance of an expanded field for landscape architecture, and possibilities for inventing flexible alliances between design teams and collaborators in “related fields such as engineering, ecology, economics, etc.”:

“Within this expanded context, landscape architects are emerging as cultural leaders; in part this is because our field already deals with complexity at very large scales, with details at very small scales, and with time and change in both the short and long run. We also accept uncertainty as part of the life of a project — landscapes are beyond our full control. Cities and metropolitan regions — among the most complex of human inventions — require this mix of big, strategic thinking and tactical, on-the-ground agility. And they demand a comfort level in dealing with change, especially unanticipated change. Projects for large areas of existing cities — like the redevelopment of 300 acres of contaminated former portlands in Toronto, or of 5.5 miles of largely industrial riverfront in Minneapolis — will take decades to be realized, through a succession of economic highs and lows, political administrations, demographic shifts, environmental challenges (like major storms), and so on.

The strategies that landscape architects develop for such places should set out strong frameworks to initiate transformation, but also be able to absorb the kind of external changes I just described. So, rather than defining strict master plans for the Toronto and Minneapolis territories — master plans which try to limit change and prescribe physical or programmatic relationships — we chose to develop strong framework plans whose contents could shift or adjust to outside influences or even internal rules, but whose final results would only come through time. This is a very different way of thinking for designers and planners — but it is, in fact, the way landscapes and cities work anyway.”

window washing


[Facade of Pharos Building, Hoofddorp, Vanessa van Dam, 2002 — never realized.]

Given our recent thinking about the role of maintenance in urban design, I was quite interested when I noticed, in a couple-year-old copy of 306090, an article by Hilary Sample (of MOS) on the potential of maintenance in architecture.  The piece, “Towers, Maintenance, and the Desire for Effortless Performance”, is well-worth reading in full, but I’ll quote one section, which deals with the project pictured above:

“Architecture relies upon a never-ending regime of labor called maintenance.  The purpose of maintenance is to restore newness to architecture by offsetting the effects of climate, environment, and time — it is an ongoing and continuous act.  Within crowded urban environments, where maintenance is unavoidably public, it has become a spectacle in its own right, fuelled by new technologies and novel techniques.  This spectacle is especially evident at the site of large transparent exterior surfaces, where the distinct machines, apparatuses, materials, and techniques of maintenance have become part of the image of the city…

Artist Vanessa van Dam’s window washing installation at the Pharos Office Tower (2003) near Amsterdam by Kohn Pederson Fox Architects, offers one such critique on the anonymous glass office building.  To explore the relationship between architecture and maintenance, van Dam proposed the installation of 85 industrial-sized window wipers typically found on airplanes and lighthouses.  While the project was never built, the wipers were designed to respond to a programmed script activated by sensors in tune with shifting local weather conditions.  The synchronicity of the mechanical facade in action, ever vigilant against the effects of weather and dirt, embodies the modernist injunction of cleanliness in robotic hyperactivity.  The addition of the black and heavy arms on the light glass and aluminum facade brings maintenance to the foreground, revealed as an object of a mechanized fantasy that threatens to overtake the architecture itself.”

Of course, the relationship of maintenance to buildings and landscapes is potentially quite different.  Where, as Sample notes, maintenance has the potential to reveal architecture “at its most vulnerable: weak and prone to constant decay”, what has excited us about maintenance in relationship to landscape is just the opposite: the potential of maintenance, as an on-going act of intentional cultivation, to harness the capability of landscape to become more complex and more productive over time, rather than decaying inexorably.  (That the traditional landscape capital project typically follows, albeit at a slower pace — first building towards maturity, before entering decline — the same pathways as buildings is, in fact, entirely the point, because it is that trajectory that we set out find alternatives to.)  It is more difficult to imagine maintenance playing this role in relationship to buildings, but that does nothing to diminish the value of the investigations Sample suggests.

phantom stories


[Homes on the outskirts of Shanghai, via Google Maps.]

A recent report in the New York Times which looks at global marriage patterns from an economic perspective contains the following fascinating excerpt, which indicates that China’s one-child policy, “combined with a cultural preference for sons and technologies that permit selective abortion”, has indirectly produced a proliferation of phantom third floors on Chinese houses:

…evidence suggests that young Chinese women and their families have in fact become much more selective in recent years.

They appear, for example, to focus more critically on the earnings potential of prospective mates. Because house size is often assumed to be a reliable signal of wealth, a family can enhance its son’s marriage prospects by spending a larger fraction of its income on housing. (Other families can follow the same strategy, of course, but when all families do so, the resulting homes are still reliable indicators of relative wealth.) Such a shift appears to have occurred.

For example, when Shang-Jin Wei, an economist at Columbia University, and Xiaobo Zhang of the International Food Policy Research Institute examined the size distribution of Chinese homes, they found that families with sons built houses that were significantly larger than those built by families with daughters, even after controlling for family income and other factors. They also generally found that the higher a city’s male-to-female ratio, the bigger the average house size of families that have sons.

Mr. Wei reports that many families with sons have begun to add a phantom third story to their homes, one that looks normal from the outside but whose interior space remains completely unfinished.

“Marriage brokers are familiar with the tactic,” he reports, “yet many refuse to schedule meetings with a family’s son unless the family house has three stories.”

This — a kind of architectural extension of ritual courting displays — could be read as an odd corollary to the American predilection for viewing the home primarily as an investment strategy, which mammoth has previously written about.  In both cases, the home’s function as shelter (or machine for living) is subsumed by its financial potential, whether it serves to display wealth or produce it — and it would be quite interesting to learn if this shift in the function of the home has had the kind of bizarre side-effects in China that it has had in the States.

parainfrastructures

We recently wrote a brief piece, “Appeal”, for the excellent architecture journal Quaderns in response to their most recent issue, “Parainfrastructures”. We used this response as an opportunity to consider why we are so drawn to infrastructural landscapes like Blue Plains — not just as sites of logistical and technological operations, but aesthetically as well:

Let us suppose for a moment that the “Parainfrastructures” which Quaderns #262 concerns itself with are a class of things, that object-parodying helium balloons hovering around Heathrow Airport to block its expansion, inflatable “instant cities” powered by air compressors, “geodesic domes, parachutes, spray-foam dwellings, zomes, space frames”, “indoor built and ephemeral complexes” colonizing the open floor plans of abandoned airports, and architectural systems of “air control” can be read as a category of architectural objects called “parainfrastructures”. Even though we will be supposing in error—because “Parainfrastructures” never seeks to delineate its subject matter by so crude a means as a definition—this seems a productive error, because it permits us to see a pervasive weirdness.

This weirdness, in the context of architectural critique, is that parainfrastructures paradoxically gain their strength and appeal from having been designed with a certain disregard for aesthetics. Parainfrastructures are constructed out of the banal materials of twentieth-century industrial innovation like synthetic fabrics, geotextiles, and industrial plastics, not the refined and expensive finishes of high-corporate architecture. Structurally, they depend on ties, straps, bendable rods, and air compressors—temporary, flexible, contingent engineering.

Read the whole piece at Quaderns and, while you’re there, think about ordering the full issue; it’s well worth your time, as it features contributions from John May, Enrique Ramirez, Roger Sauquet, Javier García-Germán, and more.

shitscape

To wrap up this week of fecal matters, I want to talk briefly about Bret Betnar’s “Shitscape: Mumbai’s Landscape In-Between”, a brilliant project done while Betnar was at the University of Pennsylvania.

1 If you haven’t already read it, be sure to check out Peter Nunns’ post from Tuesday on “fecal politics”, which deals with exactly these issues of poverty, fecal matter, infrastructure, and agency in India.

“Shitscape” describes “the making of an entirely functioning landscape built from human excreta”. It proposes to accomplish this by recovering “the ‘soil’ from the settlements while extracting the beneficial flora from the forest and, in turn, utilize both as a generator for a new and evolving landscape”. The project aims to give “those living in peri-urban” Mumbai the capacity to relieve their own “conditions of poverty” by providing a structure within which “they participate in the creation, processing and profits of this landscape”1.

Analysis of the existing site; areas currently used for toileting are shown as gray fields. (All the images in this post can be enlarged by clicking on them.)

The site for the project is the Appapada Quarry, which sits between “the northern Mumbai suburb of Malad East” and “a hillside of informal settlements”. “In the middle of the quarry is the large Appapada Maidan, used by kids and adults from varying parts of northern Mumbai. Several areas in and around the quarry environs are used for toileting by the local populace”.

Section of composting toilet unit above quarry wall.

Section above quarry wall with water catchment and filtration system.

Betnar’s methodology for doing this is both infrastructural and generative:

“‘Shitscape’ proposes three major introductory insertions: constructed trench-like composting toilets, a stone pathway traversing quarry wall and stone ‘tanks’ for the retention of water. Other minor insertions should include a slow-sand filter for availability of potable water, a grove of both coconuts and bananas to help begin the functioning of the landscape and pit toilets for use during the monsoon season.”

By infrastructural, I mean that it seeks to construct a framework which can be inserted into the landscape and used to trigger generative effects within that landscape; by generative, I refer to the tendency of landscape to multiply, transform, and alter the inputs it receives.  The construction of toilets, a pathway, a filter, and retention tanks does not directly produce a new fertile terrain. (One way, for instance, that a new fertile terrain could be directly produced would be by importing a carefully specified topsoil, as in the average landscape capital project. This is exactly what Betnar does not propose.) Rather, those infrastructures transform an input — feces — into a substance — compost — that can be applied to the landscape over time, introducing a new process to the set of processes already operating on that landscape, and creating what Betnar calls the shitscape.

Stone swales, sluices, concrete channels, contour swales, and fencing — the infrastructural vernacular of Shitscape.

The planting scheme focuses on creating an economically productive landscape, bearing fruits, timber, and Ayurvedic medicines.

Laudably, a significant portion of the Betnar’s study is devoted to considering both the potential progression of the landscape through time and its capacity to serve as a prototype for similar future landscapes:

“With water, improved soil, food supplies and the resiliency of the local population, this landscape can evolve throughout time to accommodate more varieties of produce and the potentially profitable growing of timber and Ayurvedic plant material. Additions to the water and toilet systems can be made as required by the local community. If this landscape is to be a success, it will need not only the inputs from the community, but their ingenuity in adapting the plan to their own uses. As such, it is hoped that this landscape could be maintained through multi-family networks, much like a village system. This project is designed as a prototype scenario which, if successful, could be repeated elsewhere along the western edge of the park.”

This describes one of the significant advantages of working infrastructurally and utilizing the generative capacity of landscape: because those methodologies offer opportunities to transform seemingly useless inputs into valuable material outputs, they are particularly valuable to people who lack the capacity to take advantage of more capital-intensive modes of landscape transformation.

Graphs representing “a temporal evolution of the site”, including the toileting and composting process, “development of the site’s water and pedestrian infrastructure”, and plant cultivations.  Enlarge the image to read the diagrams; note that the two diagrams — columns one and three are one continuous diagram of “Settlement: Soil”, read top to bottom through column one and then top to bottom in column three; columns two and four (“Forest: Monsoon”) have the same relationship — are keyed to the plan diagram below.

psyttaleia island

blue plains

Last spring, Mammoth visited the Blue Plains Wastewater Treatment Plant. This massive facility — which claims to be the largest plant of its particular kind in the world — exists to remove the solids that the 2 million residents of Washington, D.C. and surrounding counties in Maryland and Virginia introduce into wastewater from their parking lots, their laundry, and their toilets.

Blue Plains creates clean water by refining influent, removing particles of ever-decreasing physical scale. It separates true waste components from useful nutrients from clean water. Facilities like Blue Plains — not just sewer and wastewater treatment, but garbage dumps, power plants, distribution centers, ports, and a thousand others — are both massive and critical to the function of cities, yet often have minimal visibility. This lack of visibility can be intensely problematic, particularly in a democratic society, because it distances the public both from the utility of infrastructural facilities — which often translates into neglect and a lack of will to develop and execute long-term vision — and from any problems those facilities might create through their operation — again, resulting in a failure to improve or re-think those infrastructures.

A key theme in the contemporary operation of many infrastructural facilities, and of Blue Plains in particular, which deserves this visibility is a growing shift from linear processes (extraction, use, disposal) toward cyclical processes (use, extraction, re-use).  In an article called “Landscapes of Disassembly” in Topos 60, Pierre Belanger describes this transition:

“Though the economic and ecological histories of Europe, Asia and North America may differ, they all present compelling examples for understanding the latent reciprocity between industry, waste and urbanism. As a result of global legislation – such as the 1992 Basel Convention that prohibited the transnational movement of hazardous wastes – the pre-eminence of waste colonialismin the 20th century is now a thing of the past. Multilateral strategies, including waste diversion, separation, recycling, composting and remanufacturing, are proving effective as durable alternatives to conventional systems of waste management that previously relied on consolidated forms of disposal. With skyrocketing costs of mining, surging fuel prices and growing patterns of urbanization, exhausted economies are being jumpstarted through combined strategies of economic regeneration and ecological reclamation, where water, land, energy and waste are becoming the bedrock of a new world economy. Dismantling the Old World notion of the city, urban-industrial synergies never before possible are forming beyond metropolitan areas, signaling the birth of a new and diffused urban economic pattern that is best described as an operational ecology held together by supply chains and distribution networks.”

1Scott Huler explains this in his fascinating On the Grid, quoting a Raleigh wastewater treatment superintendent T.J. Lynch:

“All we’re doing is what a river would do… what happens in our plant  is the exact same thing that happens in a stream. That’s exactly where the process came from. We’ve just concentrated it. It might take the river a couple hundred miles to accomplish what we’d do in a couple days.”

While it’s obvious that a treatment plant handles water in this fashion (indeed, the reason plants like this were first developed was to combat the severe pollution of waterways where waste water was disposed, and the process of waste water treatment mimics — in an accelerated fashion — the natural cleaning processes of waterbodies1), this isn’t the only cycle Blue Plains engages. Take, for instance, this excerpt from a Foreign Policy essay about peak phosphorous, followed by two quotes from our tour guide:

“From Kansas to China’s Sichuan province, farmers treat their fields with phosphorus-rich fertilizer to increase the yield of their crops. What happens next, however, receives relatively little attention. Large amounts of this resource are lost from farm fields, through soil erosion and runoff, and down swirling toilets, through our urine and feces. Although seemingly mundane, this process cannot continue indefinitely. Our dwindling supply of phosphorus, a primary component underlying the growth of global agricultural production, threatens to disrupt food security across the planet during the coming century. This is the gravest natural resource shortage you’ve never heard of.”

2Unless otherwise noted, all quotes are paraphrased statements from our tour guide.

‘In 30 years, OPEC will stand for Organization of Phosphorous Exporting Countries.’ 2

‘Wastewater treatment plants are estimated to control 20% of all agricultural nutrients in the United States.’

Blue plains doesn’t just process water — it also processes all of the things that we put into water, which are very often things we need back. Our tour guide said that he preferred to think of Blue Plains as a ‘nutrient reclamation facility’ instead of merely wastewater treatment. This seems apt. Many of the newest and most impressive technologies we saw weren’t so much about making the cleanest water possible — these facilities have been very good at that for some time — but about refining what they pull from the water into a useful substance (such as biosolids for use in agriculture and brownfield rehabilitation) or processing  unusable byproducts more efficiently.

And so our blog tour is split into two parts. The first, making liquids more liquid, traces water refinement, which culminates in discharge into the Potomac. The second, making solids more solid, is about the cycles within the wastewater treatment cycle, about how we reclaim valuable matter from our feces and runoff, and configure that matter for re-use.

A final note before we begin the tour: it’s worth keeping in mind Peter Nunns’s post on fecal politics in India as you read this. The contrast here — between the struggle for something so basic as access to adequate sanitary facilities and the incredible technological forces brought to the refinement and reclamation of water and useful material from wastewater here — is as clear an example as any of the way treatment of feces mirrors a society’s values, wealth, and technological capabilities.

reversing the chicago river

One of the more spectacular engineering accomplishments of the United States in the late nineteenth century was the reversal of the Chicago River. Through the construction of a series of canals — most notably, the Chicago Sanitary and Shipping Canal, seen under construction in 1896 above — the river was made to flow not into Lake Michigan, as it did when Europeans arrived in Illinois, but away from Lake Michigan and towards the Mississippi, which it had not done since the area was covered by the prehistoric glacial Lake Chicago. As Scott Huler explains in On the Grid, this was done because of fecal matter: “…the outfalls of the sewers made such a mess of Lake Michigan that during large rainstorms the plume of tainted water flowed all the way out to the intake for the water system”, contaminating the city’s water supply.

egg digesters


[After Pruned’s unfortunately lost egg digester Flickr set, satellite photography of egg digesters heating and breaking down sludge on Deer Island, just outside Boston.]


[More egg digesters, this time at New York’s Newton Creek Wastewater Treatment Plant. A New York City press release describes the eggs:

“The digesters will process up to 1.5 million gallons of sludge everyday. Each egg, clad with low reflectivity stainless steel, is 145 feet high and 80 feet in diameter. The eight eggs were welded on site from pieces that were brought from Texas and fabricated by Chicago Bridge and Iron. It took three months to assemble each one. Although the weight for each egg is around 2 million pounds when empty; it is calculated that they may weigh up to 32 million pounds when processing sludge…

Digesters play a critical role in the wastewater treatment process. During the wastewater treatment process, organic material called sludge is removed from sewage. Sludge is “digested” and processed for beneficial use. Inside of digesters, bacteria break down this sludge into more stable materials. Heat, lack of oxygen, and time are all needed for this to happen. Much of the sludge is converted into water, carbon dioxide and methane gas. The remaining is called digested sludge. Digested sludge is then dewatered to form a cake, which, after additional processing, can be beneficially used as a fertilizer. The eggs are state of the art in digester design as the shape assists in concentrating grit at the bottom of the tank, mixing for improved digestion and the concentration of gas at the top of the tank. Each egg holds 3 million gallons of sludge.”

fecal politics

The following piece is a guest post from Peter Nunns. Peter is a recent graduate of the University of Auckland, with a MA in Political Science; mammoth readers may be familiar with him from his contributions to last summer’s discussion of the Infrastructural City. His current research interests include shelter and urban development challenges in developing-world cities, the rescaling of political economies, and the reconstitution of citizenship rights within the city. Peter hails from California, but now lives in his ancestral homeland of New Zealand.

The filmmaker Prahlad Kakkar, the auteur of the toilet documentary Bumbay, told a startled interviewer that in Bombay “half the population doesn’t have a toilet to shit in, so they shit outside. That’s five million people. If they shit half a kilo each, that’s two and a half million kilos of shit each morning.” (Mike Davis, Planet of Slums: 142)

In India, where distance from one’s own excrement can be seen as the virtual marker of class distinction, the poor, for too long having lived literally in their own shit, are finding ways to place some distance between their waste and themselves. The toilet exhibitions are a transgressive display of this fecal politics… (Appadurai, Arjun, “Deep Democracy: Urban Governmentality and the Horizon of Politics” in Public Culture: 39)

2 UNDESA 2008, 2009

“Slum” is a word with a weighty and questionable history, but in the last decade it has been “operationalized” into a small set of criteria by housing agency UN-Habitat. Although it has become commonplace to talk of “a billion slum-dwellers” globally1 , it would be more accurate to discuss the infrastructural and legal shortcomings of developing-world cities. For example, in 2010 the UN’s Global Urban Observatory estimated that  185 million Indians, or 50.7 percent of the country’s urban population, lived in slum conditions2. Actual living situations are highly diverse, ranging from Kolkata’s pavement-dwellers to Mumbai’s chawls, or run-down former factory housing, but one thing that most slums have in common is a profusion of shit.

4 Burra, Patel and Kerr 2003

According to the World Bank, in 2008 46 percent of Indian urbanites – or nine out of every ten living in a slum – lacked “improved sanitation facilities”, meaning that people living within them lack sewerage and public toilets3. Where community toilets do exist, poor maintenance and overuse often render them unsanitary before long. For example, a survey of 151 slum settlements in Mumbai conducted by Mahila Milan/NSDF found that there were 3,433 municipal toilet seats, 80 percent of which were not working, to serve one million people – a ratio of one toilet for every 1,488 people4. Likewise, a 1993 survey of half a million slum-dwellers in Kanpur found that 66 percent had no toilets. Lacking facilities, they shit in the open or in waterways.

5 Appadurai 2002: 39

6 Davis 2006, Burra, Patel and Kerr 2003, Bapat and Agarwal 2003

As a result, residents of slums face a disproportionately high disease burden, with high incidences of cholera and diarrhea. “One macabre joke among Mumbai’s urban poor is that they are the only ones in the city who cannot afford to get diarrhea. Lines at the few existing public toilets are often so long that the wait is an hour or more, and of course medical facilities for stemming the condition are also hard to find”5. But in addition to being a public health crisis, the lack of sanitation is especially concerning for women, who are most severely affected by the lack of privacy when defecating6. In public toilets, they are frequently harassed. Defecating in the open in the absence of toilets is even more risky; as a result, most women choose to do so at night or in the early hours of the morning, which in turn leads to gastric disorders.

9 McFarlane 2008: 102

There is no obvious solution to this particular infrastructural shortcoming. Because many slum settlements are illegal or informal, occupying the margins of railway lines and airports and other undeveloped land, city governments are not keen to extend sewers and other utilities into them. Funding and building public toilets is often problematic for the same reason. When the Indian government allocated money for toilet block construction in the 1990s, most of it went unspent due to city governments’ disinterest in upgrading slums. In Pune (population: 4.4. million in 20057), a municipal initiative resulted in the construction of only 22 toilet blocks between 1992 and 19998. The toilets that were built often became unusable relatively quickly due to overuse and a lack of maintenance or cleaning. Even in cases where projects were completed and maintained, the “focus on cost recovery from the poor means that sanitation is often provided not according to those who need it most, but according to how many people can pay a contribution”9.

10 Burra, Patel and Kerr 2003: 19

11 Burra, Patel and Kerr 2003: 20

I’d argue that sanitation in Indian cities is not just a challenge for urban planning and architecture; it’s also an essentially political problem. One of the most successful programs of community toilet construction involved not just new design elements but the development of what Arjun Appadurai describes as “fecal politics”. After the failure of Pune’s city government to deliver toilets, its municipal commissioner invited NGOs to bid for construction and maintenance contracts. A national shelter activist group, the Alliance between the Society for the Promotion of Area Resource Centres (SPARC), the National Slum-Dwellers Federation (NSDF), and Mahila Milan (or “Women Together” in Hindi), won a contract to build 320 toilet blocks with 6,400 seats throughout the city10. As a result, “between 1999 and 2001, more toilets were constructed and more money spent than in the previous 30 years”11. Equally important, the new toilets were designed and constructed by those living in the slums, resulting in lower building costs and several important architectural innovations.

The Alliance’s success in sanitation is a result of its particular model of political activism, which is rooted in the everyday experience of slum-dwellers but diffused among national and global networks. Its “politics of shit,” tested in Pune and subsequently replicated in Mumbai and other cities, is a response to the infrastructural and legal dilemmas facing its members. Others have written at greater length on the organization and operation of the Alliance12. Rather than duplicating all of their work, I’d like to discuss its technique of employing the knowledge and expertise of the urban poor.

Fecal politics relies upon information generated by and for slum-dwellers, testing and legitimizing new or existing uses of urban space. Appadurai describes it as “a politics of show-and-tell”, in which slum-dwellers “claim, refine, and define certain ways of doing things in spaces they already control and then use these practices to show donors, city officials, and other activists that their ‘precedents’ are good ones and encourage such actors to invest further in them.” The Alliance’s projects invariably employ community knowledge of the daily challenges of slum living – particularly in terms of housing quality and access to water and sanitation – to devise ways of improving their lives. As Burra, Patel, and Kerr note, this is appropriate given that slum-dwellers are the people who actually build cities:

People are the best experts. A long-established myth is that experts with advanced degrees are needed to plan improvements in slums. But the realities of life in India’s slums are best understood by slum dwellers themselves. If experts had a better track record, their expertise might have more credibility – but the deplorable state of infrastructure in Kanpur or Bangalore suggests there are serious holes in this “expertise”. The slums in India are home for most of those who actually build cities: masons, pipe layers, cement mixers, brick carriers, shuttering designers, stone cutters, trench diggers and metal fabricators. The poor, as they construct their own homes and neighbourhoods, are already the designers and implementers of India’s most far-reaching systems of housing and service delivery. The systems they use are not ideal, are largely “illegal”, and often inequitable, but they reach down to the poorest groups and cover far more ground and affect far more lives than any government programme could ever achieve.

Quite often, the “people” Burra et al are referring to are women. Although women still face a number of structural barriers to participation in the public sphere, as suggested by their low rate of labor force participation (in 2009, 81.1 percent of men were in the workforce, compared with only 32.8 percent of women), they are often the most knowledgeable about living conditions in slums. Most women in urban India labor in the home, performing unpaid domestic work or various types of subcontracted homework, and they are most heavily affected by the lack of water and sewerage. As a result, women play an important role within the Alliance: they are strongly represented in its leadership and are responsible for much of the financial side of slum upgrading through Mahila Milan’s savings collectives.

The politics of shit is, of course, an intrinsically local thing. What could be more intimate, more deeply particular to an individual place, than defecation? But at the same time, the lack of toilets and sewers is a problem shared by most slum communities, irrespective of their own particularities. As a consequence, the Alliance’s work tends to cross geographic scales: it integrates local struggles into national (the 750,000 members of NSDF across 52 Indian cities13) and international (Slum/Shack Dwellers International (SDI), a federation of shelter groups from Latin America, Africa and Asia14) networks. This gives the Alliance scope to scale up projects and precedents that have proven successful at a local level. This process facilitates “horizontal learning” through the exchange of slum upgrading methods, critical debate, and solidarity among shelter activists and slum-dwellers.

Practicing fecal politics has delivered concrete gains for Indian slum-dwellers. In Pune, the Alliance ultimately constructed 400 toilet blocks with roughly 20 seats apiece, which are capable of serving roughly half a million people a day provided that they are kept clean. They were designed, built, and managed by community members, those who “actually build cities”, rather than by outside contractors as is normal for such projects. In doing so, Pune’s slum-dwellers were able to draw not just upon their own experiences but on knowledge developed within the Alliance as a result of smaller-scale projects carried out in  Mumbai, Kanpur, Bangalore between 1988 and 1996 with funding from the UK charity Homeless International and from slum-dwellers themselves15.

The result was better toilet facilities constructed at a lower cost – 5 percent under municipal cost estimates, according to Burra and Patel. Design innovations made them well-lit, better-ventilated and easier to clean, important considerations given that public toilets in Indian cities have a history of becoming rapidly fouled. For example, storage tanks were increased in size to ensure that there was sufficient water for washing up and keeping facilities clean. Input from women, who are particularly vulnerable to the lack of appropriate toilet facilities, resulted in several simple but important new features. Toilet blocks were designed to reduce harassment by including separate entrances for men and women, and seats that did not directly face each other. And, recognizing that children are generally shunted aside in latrine queues, blocks of children’s toilets were also constructed. As the picture below shows, these were specifically designed to be easy for children to use, with handles, smaller openings, and child-friendly decorations16.

The Alliance recognized from the start that constructing a toilet isn’t sufficient to improve sanitation in the slums, as they must be cleaned and maintained in order to be usable. Collecting the money to do so is challenging, as it must balance usability with accessibility. “User-pays” fees for public toilets are unaffordable for many residents. They are usually set at one rupee per month – a small amount that adds up quite rapidly. Families living at the official urban poverty line of 20 rupees per person per day would strain to pay even that. Consequently, the Alliance has relied upon community organization and a system of affordable collective payments from slum households – roughly 20 rupees per month – to pay for maintenance17. In order to hold maintenance costs down, caretakers and their families are provided with a room in toilet blocks as part of their compensation.

In keeping with its principles, the Alliance has actively shared the knowledge it has developed, both within its own network and with other interested groups. Communities have put on “toilet festivals” to celebrate and publicize their new facilities, thereby reinventing “this private act of humiliation and suffering as the scene of technical innovation, collective celebration, and carnivalesque play with officials from the state, the World Bank, and middle-class officialdom in general”18. This has helped to stimulate interest in community-built and -maintained toilet blocks among city governments, other NGOs and CBOs, and the World Bank. As a result, Pune’s toilets have set a precedent for future sanitation improvements in Indian slums. For example, in 2000 the World Bank and the Mumbai Municipal Corporation funded the Alliance to construct 320 similar toilet blocks in that city19. In 2001, the Alliance’s successes in Pune and Mumbai encouraged the national government to provide subsidies for similar public toilet construction programs20.

There are many more things that could – and should – be said on fecal politics. I’ve hinted at a few of them here. Obviously, there is a lot more to say about the architectural practice that it might generate. But speaking for a moment as a political scientist, what I find fascinating about the work of the Alliance is the way that it alters the meaning of citizenship. If the politics of shit is a way for slum-dwellers to “place some distance between their waste and themselves” – both literally and figuratively – it is also a way for them to claim the right to live in the city. When Bapat and Agarwal interviewed slum-dwellers in Pune and Mumbai about water and sanitation issues, a recurring complaint was about their own invisibility to politicians and planners. By building their own toilets, and then showing them off in toilet festivals, they reclaim some of the legitimacy denied to them by governments.

fecal matters

This week — really, we promise it will just be a week — we’ll be looking at landscapes of shit.  We’ll take a guided tour of DC’s huge wastewater treatment plant, Blue Plains, we’ll have an excellent guest post from Peter Nunns on “fecal politics”, we’ll look at a student project that proposes “the making of an entirely functioning landscape built from human excreta”, and there may be a few other miscellaneous items.  This should be fun.
