  • Extending the water safety plan concept to the urban water cycle

    The urban water cycle (UWC) is often managed by several stakeholders dealing with specific components of the cycle such as water supply, wastewater systems and water bodies management. Therefore, risk management in the UWC benefits from an integrated approach to incorporate the interdependencies between elements. The water cycle safety plan (WCSP) provides a common risk management framework for ...

  • A decision support system for water supply emergency management with multiple sources

    The construction of water transfer projects brings new challenges to water resources management, especially in water supply security with the use of multiple water sources. However, the operations of water diversion and water supply have been considered in separation in practice. In particular, there are few decision support systems (DSS) designed to tackle the challenges in emergency planning ...

  • Water supply methods in Ancient Thera: the case of the sanctuary of Apollo Karneios

    The same natural water sources which enabled people to settle the island of Thera in the 8th century BC, are still visible today on the hill of Mesa Vouno. An extensive infrastructure for the exploitation of rainwaters was established in the city of Ancient Thera on Mesa Vouno, which is striking for the quality of its construction as well as the inventiveness of its builders. Rainwater followed ...

  • Effects of rainwater harvesting on centralized urban water supply systems

    The potential effect of widespread rainwater harvesting practices on mains water demand and quality management are investigated for three different types of urban areas characterized by different roof area to water demand ratios. Two rainfall patterns are considered with similar average annual depths but very different temporal distributions. Supply reliability and the extent of reliance on the ...

  • Risk assessment study for water supply network using GIS

    In recent years, contamination of water in water distribution systems (WDS) has been recognized as a major cause of waterborne diseases. Owing to old and deteriorated pipes, and the presence of pollution sources in contact with the supply line, water boards often decide to replace the network in the interests of public health. This being a cost-intensive and time-consuming programme, decision ...

  • Adaptation of surface water supply to climate change in central Iran

    Optimal reservoir operation changes and adaptation strategies for the Zayandeh-Rud River Basin's surface water supply system are examined for a changing climate during the 2015–2044 period. On average, the monthly temperature in the basin is expected to increase by 0.46–0.76 °C and annual precipitation is expected to decrease by 14–38% with climate ...

  • Delivering water supply and sanitation in fragile states : the transition from emergency to development

    Addressing the challenges of Fragile and Conflict-Affected Situations (FCS) is a priority for the World Bank Group and other development partners. Despite substantial aid flows, current modes of support from the international community have not sufficiently achieved stated goals of reducing poverty, increasing stability and strengthening institutions. This note captures the main points and ...

  • Water and energy futures for Melbourne: implications of land use, water use, and water supply strategy

    This paper quantifies the effect of three policy levels on the water and energy futures of Melbourne, Australia. During a time of severe water shortages attributed to climate change, water strategies lacked consideration of energy consequences. Modeling, guided by urban metabolism theory, demonstrated that a compact urban form, reduced water consumption by 90 GL/a, compared with a sprawling ...

  • Securing safe drinking water supply under climate change conditions

    Water suppliers worldwide are challenged by climate variations, but so far only the qualitative change in boundary conditions has become clear but not yet the degree and impact on the water supply systems. Short-term quality changes in surface waters can, e.g. be caused by extreme rainfalls after dry periods. Longer heat periods without rain can induce middle-term quality changes in surface ...

  • Planning and installation of a drinking water treatment in Gunungkidul, Java, Indonesia

    The district of Gunungkidul on Java Island in Indonesia is affected by an acute water shortage, especially during dry seasons. Because of its karst topography, rainfall percolates rapidly into underground caves, limiting surface storage. As a consequence, potential sources of water to supply the local population are rainwater and water derived from underground caves. However, water availability ...
