Water is indispensable ‘stuff’ for maintaining the metabolism, not only of our human bodies, but also of the wider social fabric. The very sustainability of cities and the practices of everyday life that constitute ‘the urban’ are predicated upon and conditioned by the supply, circulation, and elimination of water. The complex web of the ‘Metabolisms of Cities’ (Wolman 1965: 179) relies on the perpetual circulation of water into, through, and out of the city. Without an uninterrupted flow of water, the maelstrom of city life and the mesmerizing collage of interwoven practices that constitute the very essence of urbanity are hard to imagine. It is difficult, if not impossible, for most of us to even think about living without water for drinking, washing, bathing, cooking, or cleaning for more than a few hours. Indeed, like food, water is both a biological necessity and a key economic commodity, as well as being the source of an intricate and rich cultural and symbolic power (see Bachelard 1942). But while the supply of food, clothing, and durable goods can be handled through local, decentralized, individual initiative, the supply of water is routinely— although by no means necessarily or exclusively—organized by means of large bureaucratic and engineering control systems, collective intervention and action, and centralized decision-making systems (see Wittfogel 1957;Worster 1985; Lorrain 1997; Donahue and Johnston 1998). Such centralized and hierarchical systems, whether privately or publicly owned, enable monopoly control and, given the commodity character of water, permit the extraction of monopoly profits in addition to the powerful social and political control that goes with monopolistic control over vital goods. Contrary to the rural realm where—at least under non-arid conditions—water of a reasonable quality is easily and often readily available, urban water supply and access relies on the perpetual transformation, mastering, and harnessing of ‘natural’water. Urban water is necessarily transformed, ‘metabolized’ water, not only in terms of its physico-chemical characteristics, but also in terms of its social characteristics and its symbolic and cultural meanings.

AbstractDue to population growth, the city of Gitega in the central part of Burundi is lacking drinking water. Therefore, the national urban water supply company decided to expand the Nyanzari wellfield by drilling additional wells.Two additional wells were drilled to 80 m (F7.2) and 85 m (F8bis) depths. Step tests followed by 72-hours aquifer tests were performed in each well. Results indicate bilinear flow followed by linear flow and radial flow in F7.2. No reaction was observed in observation wells. Fracture-matrix transmissivity was estimated at 3 · 10−4 m2/s. In the case of F8bis, linear flow in an infinite flow fracture followed by radial flow was visible. Reaction was measured in observation wells. Transmissivity was estimated at 3.3 · 10−3 m2/s.Both wells lie no more than 300 m apart, but no evidence of interference between them was depicted during the tests. It appears that two independent fracture systems prevail in the wellfield.

Abstract. Combining historical climatology and environmental history, this article examines the diverse range of strategies deployed by the city government of Barcelona (Catalonia, NE Spain) to confront the recurrent drought episodes experienced between 1626 and 1650. Our reconstruction of drought in Barcelona for the period 1525–1821, based on pro pluvia rogations as documentary proxy data, identifies the years 1626–1635 and the 1640s as the most significant drought events of the series (highest drought frequency weighted index and drought duration index). We then focus on the period 1601–1650, providing a timeline that visualises rain rogation levels in Barcelona at a monthly resolution. Against this backdrop, we examine institutional responses to drought and discuss how water scarcity was perceived and confronted by Barcelona city authorities. Among the several measures implemented, we present the ambitious water supply projects launched by the city government, together with the construction of windmills as an alternative to watermills, as a diversification strategy aimed at coping better with diminishing water flows. We pay special attention to the institutional efforts to codify the knowledge about Barcelona's water supply, which in 1650 resulted in the Book of Fountains of the City of Barcelona (Llibre de les Fonts de la Ciutat de Barcelona). This manual of urban water supply, written by the city water officer after 3 decades of experience in his post, constitutes a rare and valuable source to study water management history but also includes significant information to interpret historical climate. We analyse the production of this manual in the context of 3 decades marked by recurrent episodes of severe drought. We interpret the city government aspiration to codify knowledge about urban water supply as an attempt to systematise and store historical information on infrastructure to improve institutional capacities to cope with future water scarcities.

Groundwater is an excellent alternative to meet public water supply demands, especially in the face of the water crisis and pollution of surface water bodies. Many municipalities throughout the national territory use water from springs for urban water supply. Barra Mansa, a city located in the southern Fluminense region, is an example of this. The aim of this study was to evaluate the water quality of three springs located in the city of Barra Mansa, in order to verify its water potential. The results obtained showed the water potential of the Municipality, revealing, however, the state of degradation and the risk of contamination of groundwater, imposing the need to develop measures to preserve, prevent and mitigate anthropic impacts on the water sources. In this way, the questions proposed here may contribute to a reflection about the exploration of the sources and the implications inherent to its use.

This year marks the 190th birthday of the famous Swiss architect of Italian origin A.I. Bernardazzi, who is also known for creating various historic buildings in Ukraine, Bessarabia and Poland. Archival documents were an evidence of the beginning of architectural career of Bernardazzi, when the Bessarabian Road and Construction Commission appointed him as the technician for urban planning of Akkerman and Bendery in 1853 and also for building some bridges and causeways in those districts. He took part in the organization of the third market in the Forest Square in Kishinev in September of 1855. This was the first mission of his creativity in Kishinev. Alexander Bernardazzi executed his duty as municipal architect from 1856 to 1878 having taken the place of another architect Luca Zaushkevich. All his subsequent monumental buildings became the best examples of European architecture by their style, shape, and quality. . In Bessarabia, he participated in the design and construction of many buildings such as the temporal theatre, the Lutheran school, the railway station, the Greek Church, the Manuk-Bei’s palace, etc. As for Kishinev, the architect Bernardazzi performed the beautification of paving many streets, the construction of urban water supply and the cast-iron railing in the city park. Also, he participated in many architects’ meetings where he submitted interesting reports referring to the theater, some windows, fire safety of buildings and so on. After his arrival to Odessa in 1878, Alexander Bernardazzi continued to participate in designing social and civil buildings in Bessarabia. For his enormous creative contribution to urban development, he was appreciated with the title of honorable citizen of Kishinev and appointed member of the Bessarabian department of the Imperial Russian Technical Society.

This paper is a study on financial sustainability of water supply service to the city of Offa, in Kwara State, Nigeria. The value consumers place on water supply and the willingness-to-pay (WTP) for improved service and the factors that influence their preferences were determined using an econometric model. The WTP was estimated using a double-bounded dichotomous model and the mean WTP was found to be 70% higher than the current tariff, while the expected monthly revenue from domestic customers alone was 21 million ($175,000)1. The study revealed that the consumers were not satisfied with the level of service but they were willing to pay for improved service and even support reforms that will bring about this change. The mean WTP in practical terms gives social benefit of a policy for the offered service for the affected population. The study outcome shows that the high WTP is a good incentive for private sector involvement in the management of urban water supply.

This paper explores a renewed problematization of contemporary metropolises' dynamics in the light of speci fic efforts to reclaim the city as commons. Building on Lefebvre's theorizations of the city's virtuality and comparing it to contemporary approaches to the urban condition that emphasize the potentialities of contemporary city-life, it suggests that urban commoning is unleashing the power of collective creativity and collaboration. Struggles to appropriate the city as a crucial milieu for sharing transforms parts of city and produces new patterns of urban living. Examples from Latin American urban movements focused on establishing emancipatory housing conditions are used to illustrate the transformative capabilities of urban commoning.
