  • Impacts of variable energy prices on the financial sustainability of water facilities: case from Ghana

    Water is conveyed to consumers through systems that generally rely heavily on energy. The dependence on energy is a major challenge to utility providers because of frequent variation in energy prices. This paper assesses the effect of energy price changes on the financial sustainability of water facilities. It further investigates the proportion of energy cost to total costs of water supply. The ...

  • Introduction

    Different definitions of water governance will be reviewed and the question will be asked: Why is water governance important? Subsequently, some theoretical insights will be reviewed concerning the factors influencing successful water governance. A theoretical framework will be provided. Currently, water governance structures are often not able to deal with these factors, which require reform and ...

  • The cubic water Kuznets curve: patterns of urban water consumption and water policy effects

    Utilizing panel data collected in 27 countries from 1960 to 2010, we demonstrate that the relationship between per capita urban water consumption and per capita gross domestic product exhibits an N-shaped pattern. Following the environmental Kuznets curve literature, this relationship can be named the cubic water Kuznets curve. We also demonstrate that water policies significantly influence ...

  • Water and the city: exploring links between urban growth and water demand management

    Urban water management is currently understood as a socio-technical problem, including both technologies and engineering interventions as well as socioeconomic dimensions and contexts vis-à-vis both end users and institutions. In this framework, perhaps the most important driver of urban water demand, at the intersection between engineering, social and economic domains, is urban growth. ...

  • Capacity attributes of future urban water management regimes: projections from Australian sustainability practitioners

    Transitioning to more sustainable urban water management is widely accepted as an essential societal objective. While there has been significant progress in developing technical solutions to the challenges faced, numerous barriers remain at the regime level, indicating that further investigation into the regime is required. This paper reports on a social research project aimed at identifying ...

  • Realising sustainable urban water management: Can social theory help?

    It has been acknowledged, in Australia and beyond, that existing urban water systems and management lead to unsustainable outcomes. Therefore, our current socio-technical systems, consisting of institutions, structures and rules, which guide traditional urban water practices, need to change. If a change towards sustainable urban water management (SUWM) practices is to occur, a transformation of ...

  • Working towards sustainable urban water management: the vulnerability blind spot

    The unprecedented water scarcity in Australia coincides with the adoption of a new urban water rhetoric. The ‘Security through Diversity’ strategy has been adopted in a number of Australian cities as a new and innovative approach to urban water management. Although this strategy offers a more holistic approach to urban water management, in practice, the Security through Diversity strategy is ...

  • Multiple conceptions of sustainable urban water systems: problem or asset?

    This paper examines various conceptions that researchers and practitioners in the sector have about sustainable urban water systems, to discern what these conceptions are and whether they are complementary or divergent. The study is based on a literature review and field studies, including semi-structured interviews. The results show that the conceptions held by the various actors are largely ...

  • Prediction of urban water demand on the basis of Engel's coefficient and Hoffmann index: case studies in Beijing and Jinan, China

    Domestic and industrial water uses are the most important segment of urban water consumption. Traditional urban water demand models are usually based on water consumption quotas or statistical relationships, which usually overestimate urban water demands. The efficiency of domestic and industrial water uses is associated with living standards and levels of industrialization. The correlation ...

  • Promoting voice and accountability in urban water and sanitation services : lessons on introducing demand side accountability tools in Kenya

    The introduction of the Citizen Report Card (CRC) tool in three Kenyan cities formed a basis for dialogue between citizenry and decision makers on urban water and sanitation issues. The CRC replicates the private sector practice of collecting and acting on consumer data for self improvement, but applies it to public goods and services, framed in an open and public consultative process. The CRC ...

  • A mathematical approach to find long-term strategies for the implementation of resource-orientated sanitation

    In the present discussion of sustainability centralised water infrastructures are exposed to new challenges, which may cause a conceptual alteration in urban water management. If technologies for closing urban water and nutrient cycles are to at least partially replace existing systems, then intensive reconstruction work becomes essential. The paper presents the development and implementation of ...

  • Inequality and polarization analysis of urban water use in the Yangtze River Delta area, China

    Inequality and polarization are terms usually used to describe the overall dispersion of income distribution and the phenomenon of a divided society with a disappearing middle class and increasing rich and poor populations. However, these terms have seldom been used in water sciences. In this paper, the concepts of inequality and polarization are employed to analyze the distribution of urban ...

  • Integrated water resource planning in the context of climate uncertainty

    In many locations, climate change may significantly reduce urban water supplies and could also affect water demand. With uncertainty around future climate, supply-demand planning needs to adapt. This paper addresses the question: How does climate change alter Integrated Resource Planning (IRP) for urban water? The paper covers the setting of planning objectives in the face of climate change, ...

  • Modelling the urban water cycle as an integrated part of the city: a review

    In contrast to common perceptions, the urban water infrastructure system is a complex and dynamic system that is constantly evolving and adapting to changes in the urban environment, to sustain existing services and provide additional ones. Instead of simplifying urban water infrastructure to a static system that is decoupled from its urban context, new management strategies use the complexity ...

  • Water service governance, technological change and paradigm shifts: a conceptual framework

    This article offers a conceptual framework of the social factors enabling and inhibiting paradigm shifts in urban water supply and sanitation. We understand paradigm shifts as radical changes in the metabolism of urban water services, whereby change is informed by a distinct ethos. We reframe paradigm shifts as the function of two factors: 1) the agency of paradigm advocacy; 2) the institutional ...

  • A socio-technical model to explore urban water systems scenarios

    This article reports on the ongoing work and research involved in the development of a socio-technical model of urban water systems. Socio-technical means the model is not so much concerned with the technical or biophysical aspects of urban water systems, but rather with the social and institutional implications of the urban water infrastructure and vice versa. A socio-technical model, in the ...

  • Why is Germany 30 years ahead of England?

    The question is asked why Germany in the field of water management is 30 years ahead of England? In terms of the delivery of integrated urban water management technologies, Germany is indeed 20 to 30 years in advance of England. The comparison is made on 12 dimensions and illustrates how dramatic the effect of governance can be in the adoption of innovations in water management and hence the ...

  • Efficient multi-objective optimization methods for computationally intensive urban water resources models

    Multi-objective optimization methods require many thousands of objective function evaluations. For urban water resource problems such evaluations can be computationally very expensive. The question as to which optimization method is the best choice for a given function evaluations budget in urban water resource problems remains unexplored. The main objective of this paper is to address this ...
