  • Institutional trajectory for diffusing on-site wastewater treatment in urban China

    Urban water scarcity has been an issue for a long time in China while water pollution has attracted more and more attention over the last two decades. Recently, on-site wastewater treatment (OST) has been proposed as a meaningful alternative to deal with both water pollution and water scarcity in cities in a more sustainable way. However, the diffusion of such an OST system is still slow and ...

  • Optimization techniques for leakage management in urban water distribution networks

    Reduction of leakages in water distribution systems (WDSs) is one of the major concerns for water industries. This paper presents a leakage reduction technique using pressure management by optimizing the water level in storage tanks, along with optimized control and localization of pressure-reducing valves (PRVs) in WDSs. A new mathematical tank and pump simulation algorithm is presented for ...

  • Flood forecasting within urban drainage systems using NARX neural network

    Urbanization activity and climate change increase the runoff volumes, and consequently the surcharge of the urban drainage systems (UDS). In addition, age and structural failures of these utilities limit their capacities, and thus generate hydraulic operation shortages, leading to flooding events. The large increase in floods within urban areas requires rapid actions from the UDS operators. ...

  • Urban Water and Sanitation Services; An IWRM Approach (GWP 2006)

    In this paper an attempt is made to consider IWRM approaches to urban water management in a broader way. While appropriate managment tools will be considered, attention is focussed on institutional design, decision-making scale, governance and the critical question of impledmentation practice. ...

  • Criteria and Performance Measures for Iskandar Malaysia Urban Water Shortages Management

    In Malaysia, usage of performance indicators are still new and evaluation of water utilities performance in each state are not standardized. In Iskandar Malaysia, with shortages predicted by the year 2025, new water alternatives and management measures needed to overcome this problem. Thus, criteria and performance measures were outlined for the selection of alternative water supply management. ...

  • 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 ...

  • Climate adaptive urban planning and design with water in Dutch polders

    The existing water management in Dutch polders is based on independent water systems for each polder. These are featuring artificial stabilized ground and surface water levels. As a result of the local climate the water levels in the polders are not continuously at a constant level. To maintain a stable water table in the polders, the surplus of relatively clean rainwater has to be pumped away ...

  • An assessment of sub-standard water pressure in South African potable distribution systems

    Sub-standard residual water pressures in urban water distribution systems (WDS) are a prevalent phenomenon in developing countries – South Africa being no exception. The phenomenon of sub-standard pressure is poorly understood, with intermittent supply ultimately resulting when there is no residual pressure left in the system. This research addressed the prevalence and extent of sub-standard ...

  • Vacuum sewerage systems – a solution for fast growing cities in developing countries?

    Developed more than a century ago, the potential of vacuum sewerage systems remains underexploited. At the same time, the rapid urbanization in Asia brings about major challenges for municipal utilities. In this context, the GIZ (Deutsche Gesellschaft fuer Internationale Zusammenarbeit) project ‘Integrated Resource Management in Asian Cities: the Urban Nexus’ gives technical advice to ...

  • Water quality index as a tool for wetland restoration

    Worldwide, wetlands are subjected to increasing anthropogenic pressures resulting in loss of their hydrological and ecological functions. Such impacts are more pronounced in the case of wetlands in urban areas which are exposed to land use changes and increased economic activities. In many Indian cities, natural water bodies such as lakes are heavily polluted due to runoff from farmlands in ...

  • Permeable (pervious) pavements and geothermal heat pumps: addressing sustainable urban stormwater management and renewable energy

    Water and energy are the two most fundamental ingredients of modern civilisation and are also the most precious and essential resources around the globe. They are inseparably coupled and with increasing pressures on these resources as the world's populations grow, the concepts of a combined approach can be applied while addressing the economic, climate, water and energy crises. Sustainable ...

  • Flood analysis in mixed-urban areas reflecting interactions with the complete water cycle through coupled hydrologic-hydraulic modelling

    The potential devastating effects of urban flooding have given high importance to thorough understanding and management of water movement within catchments, and computer modelling tools have found widespread use for this purpose. The state-of-the-art in urban flood modelling is the use of a coupled 1D pipe and 2D overland flow model to simultaneously represent pipe and surface flows. This method ...

  • 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 ...

  • Risk perceptions and receptivity of Australian urban water practitioners to stormwater harvesting and treatment systems

    Stormwater harvesting and treatment will be critical systems within water-sensitive cities. Although water practitioners acknowledge the importance of developing stormwater as a water source, their risk perceptions might be barriers. Risk perceptions can be understood within a receptivity framework, with awareness, association, acquisition and application components. In this study, water ...

  • A real options approach to the design and architecture of water supply systems using innovative water technologies under uncertainty

    Water supply has become a priority for developed and developing nations of the world. Conventional water resources alone cannot meet the growing demand for water in urban cities. Management of the problem is amplified by uncertainty associated with different development strategies. Singapore has limited conventional water resources and progressively architects its water supply system through ...

  • Improving equity in intermittent water supply systems

    The problems of limited financial resources and water scarcity in urban areas of developing countries are of concern to water managers following growing demand–supply imbalance. As a result, an intermittent supply is widely adopted as a measure for controlling water demand among consumers. However, ensuring equitable water distribution at low cost in intermittent water supply systems ...

  • Material flow analysis of pollutants in Taiwan

    We present a material flow analysis (MFA) of biological oxygen demand (BOD5) and suspended solids (SS) in estuaries located on the northern and southern coasts of Taiwan. Using data from 1992–2000, we examine human economic activities in each watershed to predict associated pollutant flows. This estimate is compared to data collected at monitoring stations. The ratio allows us to calculate each ...
