  • On data requirements for calibration of integrated models for urban water systems

    Modeling of integrated urban water systems (IUWS) has seen a rapid development in recent years. Models and software are available that describe the process dynamics in sewers, wastewater treatment plants (WWTPs), receiving water systems as well as at the interfaces between the submodels. Successful applications of integrated modeling are, however, relatively scarce. One of the reasons for this ...

  • Combining multimedia models with integrated urban water system models for micropollutants

    Integrated urban water system (IUWS) modeling aims at assessing the quality of the surface water receiving the urban emissions through sewage treatment plants, combined sewer overflows (CSOs) and stormwater drainage systems. However, some micropollutants tend to appear in more than one environmental medium (air, water, sediment, soil, groundwater, etc.). In this work, a multimedia fate and ...

  • Integrating water distribution system efficiency into the water conservation strategy for California: a Los Angeles perspective

    Improving water management in California requires a transition from imported to local water resources used efficiently. To assess this transitional capacity of water retailers in metropolitan Los Angeles County, we focused on a key water management metric: the water distribution efficiency. We traced the evolution of water loss reduction policy and practices globally with emphasis on ...

  • An integrated system dynamics – cellular automata model for distributed water-infrastructure planning

    Modern distributed water-aware technologies (including, for example, greywater recycling and rainwater harvesting) enable water reuse at the scale of household or neighbourhood. Nevertheless, even though these technologies are, in some cases, economically advantageous, they have a significant handicap compared to the centralized urban water management options: it is not easy to estimate a ...

  • An integrated approach for urban water quality assessment

    This paper introduces an integrated approach for the assessment of receiving water quality and the relative contribution of the urban drainage system to perceived receiving water quality problems. The approach combines mass balances with relatively simple receiving water impact models. The research project has learned that the urban drainage system is only one of the determining factors with ...

  • New trends in power and desalination integrated systems

    Demand for desalinated water has increased sharply in recent years, not only in desert areas but also worldwide. To be able to meet such challenging future demand whilst maintaining reasonable water costs that can be sustained by the end users, real water management should be developed. This should include the limitation of leakages in the water distribution mains, adequate design of end user ...

  • Integrated assessment and scenarios simulation of urban water security system in the southwest of China with system dynamics analysis

    The demand for global freshwater is growing, while global freshwater available for human use is limited within a certain time and space. Its security has significant impacts on both the socio-economic system and ecological system. Recently, studies have focused on the urban water security system (UWSS) in terms of either water quantity or water quality. In this study, water resources, water ...
