Based on fieldwork among state officials, NGOs, politicians, and activists in Costa Rica and Brazil, A Future History of Water traces the unspectacular work necessary to make water access a human ...right and a human right something different from a commodity. Andrea Ballestero shows how these ephemeral distinctions are made through four technolegal devices—formula, index, list and pact. She argues that what is at stake in these devices is not the making of a distinct future but what counts as the future in the first place. A Future History of Water is an ethnographically rich and conceptually charged journey into ant-filled water meters, fantastical water taxonomies, promises captured on slips of paper, and statistical maneuvers that dissolve the human of human rights. Ultimately, Ballestero demonstrates what happens when instead of trying to fix its meaning, we make water’s changing form the precondition of our analyses.
Supplying water to millions is not simply an engineering and logistical challenge. As David Soll shows in his finely observed history of the nation's largest municipal water system, the task of ...providing water to New Yorkers transformed the natural and built environment of the city, its suburbs, and distant rural watersheds. Almost as soon as New York City completed its first municipal water system in 1842, it began to expand the network, eventually reaching far into the Catskill Mountains, more than one hundred miles from the city.Empire of Waterexplores the history of New York City's water system from the late nineteenth century to the early twenty-first century, focusing on the geographical, environmental, and political repercussions of the city's search for more water.
Soll vividly recounts the profound environmental implications for both city and countryside. Some of the region's most prominent landmarks, such as the High Bridge across the Harlem River, Central Park's Great Lawn, and the Ashokan Reservoir in Ulster County, have their origins in the city's water system. By tracing the evolution of the city's water conservation efforts and watershed management regime, Soll reveals the tremendous shifts in environmental practices and consciousness that occurred during the twentieth century. Few episodes better capture the long-standing upstate-downstate divide in New York than the story of how mountain water came to flow from spigots in Brooklyn and Manhattan.
Soll concludes by focusing on the landmark watershed protection agreement signed in 1997 between the city, watershed residents, environmental organizations, and the state and federal governments. After decades of rancor between the city and Catskill residents, the two sides set aside their differences to forge a new model of environmental stewardship. His account of this unlikely environmental success story offers a behind the scenes perspective on the nation's most ambitious and wide-ranging watershed protection program.
Source Separation and Decentralization for Wastewater Management sets up a comprehensive view of the resources involved in urban water management. It explores the potential of source separation and ...decentralization to provide viable alternatives to sewer-based urban water management. The book presents a comprehensive view of the state of the art of source separation and ecentralization. It discusses the technical possibilities and practical experience with source separation in different countries around the world. The area is in rapid development, but many of the fundamental insights presented in this book will stay valid.
Supplying piped water intermittently is a common practice throughout the world that increases the risk of microbial contamination through multiple mechanisms. Converting an intermittent supply to a ...continuous supply has the potential to improve the quality of water delivered to consumers. To understand the effects of this upgrade on water quality, we tested samples from reservoirs, consumer taps, and drinking water provided by households (e.g. from storage containers) from an intermittent and continuous supply in Hubli–Dharwad, India, over one year. Water samples were tested for total coliform, Escherichia coli, turbidity, free chlorine, and combined chlorine. While water quality was similar at service reservoirs supplying the continuous and intermittent sections of the network, indicator bacteria were detected more frequently and at higher concentrations in samples from taps supplied intermittently compared to those supplied continuously (p < 0.01). Detection of E. coli was rare in continuous supply, with 0.7% of tap samples positive compared to 31.7% of intermittent water supply tap samples positive for E. coli. In samples from both continuously and intermittently supplied taps, higher concentrations of total coliform were measured after rainfall events. While source water quality declined slightly during the rainy season, only tap water from intermittent supply had significantly more indicator bacteria throughout the rainy season compared to the dry season. Drinking water samples provided by households in both continuous and intermittent supplies had higher concentrations of indicator bacteria than samples collected directly from taps. Most households with continuous supply continued to store water for drinking, resulting in re-contamination, which may reduce the benefits to water quality of converting to continuous supply.
•Water quality was compared in an intermittent and continuous distribution system.•Indicator bacteria were detected at higher concentrations in intermittent taps.•A higher percentage of samples from continuous taps met free chlorine guidelines.•There was evidence of intrusion in the intermittent distribution network.•Drinking water stored in households with continuous supply became recontaminated.
In recent months, it has directed its operations to Iraqi hydroelectric dams - in particular, the Mosul dam. The Water Convention that was forged under the auspices of the United Nations Economic ...Commission for Europe in 1992 is one such notable agreement.
Water lies at the intersection of landscape and infrastructure, crossing between visible and invisible domains of urban space, in the tanks and buckets of the global South and the vast subterranean ...technological networks of the global North. In this book, Matthew Gandy considers the cultural and material significance of water through the experiences of six cities: Paris, Berlin, Lagos, Mumbai, Los Angeles, and London. Tracing the evolving relationships among modernity, nature, and the urban imagination, from different vantage points and through different periods, Gandy uses water as a lens through which to observe both the ambiguities and the limits of nature as conventionally understood. Gandy begins with the Parisian sewers of the nineteenth century, captured in the photographs of Nadar, and the reconstruction of subterranean Paris. He moves on to Weimar-era Berlin and its protection of public access to lakes for swimming, the culmination of efforts to reconnect the city with nature. He considers the threat of malaria in Lagos, where changing geopolitical circumstances led to large-scale swamp drainage in the 1940s. He shows how the dysfunctional water infrastructure of Mumbai offers a vivid expression of persistent social inequality in a postcolonial city. He explores the incongruous concrete landscapes of the Los Angeles River. Finally, Gandy uses the fictional scenario of a partially submerged London as the starting point for an investigation of the actual hydrological threats facing that city.
The capital of the Aztec empire, Tenochtitlan, was, in its era, one of the largest cities in the world. Built on an island in the middle of a shallow lake, its population numbered perhaps 150,000, ...with another 350,000 people in the urban network clustered around the lake shores. In 1521, at the height of Tenochtitlan's power, which extended over much of Central Mexico, Hernando Cortés and his followers conquered the city. Cortés boasted to King Charles V of Spain that Tenochtitlan was "destroyed and razed to the ground." But was it?Drawing on period representations of the city in sculptures, texts, and maps, The Death of Aztec Tenochtitlan, the Life of Mexico City builds a convincing case that this global capital remained, through the sixteenth century, very much an Amerindian city. Barbara E. Mundy foregrounds the role the city's indigenous peoples, the Nahua, played in shaping Mexico City through the construction of permanent architecture and engagement in ceremonial actions. She demonstrates that the Aztec ruling elites, who retained power even after the conquest, were instrumental in building and then rebuilding the city. Mundy shows how the Nahua entered into mutually advantageous alliances with the Franciscans to maintain the city's sacred nodes. She also focuses on the practical and symbolic role of the city's extraordinary waterworks—the product of a massive ecological manipulation begun in the fifteenth century—to reveal how the Nahua struggled to maintain control of water resources in early Mexico City.
