  • Water management solutions minimize flood damage

    Human societies around the world have used timber as a building material for thousands of years. As wood is the only significant biological building material we are naturally inclined to believe that using wood in construction is good for the environment. As a matter of fact the environmental benefits of using timber are not straightforward: although it is a natural product, a large amount of ...

  • Construction of delicate systems to manage water distribution systems and minimize water losses: endeavors and challenges in Beijing

    The rapid population growth in Beijing exacerbates the contradiction between social and economic development and water resource shortage. The provision of sufficient and safe drinking water with reasonable pressure to local residents is the primary goal for Beijing Waterworks Group. The South-to-North Water Diversion Project is valuable to alleviate the water resource crisis in Beijing; however, ...

  • Consequence management of chemical intrusion in water distribution networks under inexact scenarios

    The US Environmental Protection Agency (EPA)'s Response Protocol Toolbox provides a list of recommendations on actions that may be taken to minimize the potential threats to public health following a contamination threat. This protocol comprises three steps: (1) detection of contaminant presence, (2) source identification and (3) consequence management. This paper intends to explore ...

  • Vulnerability of complex critical systems: case water supply and distribution networks

    Management of complex, interdependent critical infrastructures demands systematic continuity evaluations and capability building for abnormal as well as normal conditions. The changing risk and threat environment creates new vulnerabilities that require an extensive approach to control weak points and support the undisturbed and reliable functions of critical infrastructures. The water ...

  • Managing risks from virus intrusion into water distribution systems due to pressure transients

    Low or negative pressure transients in water distribution systems, caused by unexpected events (e.g. power outages) or routine operation/maintenance activities, are usually brief and thus are rarely monitored or alarmed. Previous studies have shown connections between negative pressure events in water distribution systems and potential public health consequences. Using a quantitative microbial ...

  • Assessment of real losses in potable water distribution systems: some recent developments

    ABSTRACTConsiderable progress has been made over the past 10 years in the assessment and benchmarking of real losses in potable water distribution systems. Most of the advances have been based on the burst and background estimate (BABE) methodology, which was first developed in the mid-1990s by the UK water industry and has since been widely accepted and used in many parts of the world. Since ...

  • Research on minimizing electric power usage in water distribution system

    The purpose of this study is to propose the optimal water supply control and management plan for minimizing power usage by water distribution pumps. The key topic of this study is to determine from which treatment plants water should be supplied, and through which supply stations it should be distributed. This study devised an optimal model of the ‘route/flow decision problem’ for ...

  • The joint effect of water price changes and pressure management, at the economic annual real losses level, on the system input volume of a water distribution system

    This study attempts to examine the factors affecting the residential water demand level in the city of Kozani in Greece. Based on an 8-year (2005–12) detailed sample of residential water demand panel data, the values of the water price (WP) elasticity of residential demand are identified, and the influence of socio-economic and demographic factors and climate conditions on water-use levels and ...

  • 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 ...

  • Real-time Total Microbial Measurement For Water Distribution Systems

    A well-managed water distribution system is essential for maintaining a healthy water supply. The World Health Organization, the directing and coordinating authority on health (World Health Organization, 2008), has compiled the Water Safety Plan which reflects this. With over 2.3 million deaths per year caused by water born diseases (Davidson, et al., 2005), safeguarding water systems is of ...

  • Water distribution system model calibration under uncertainty environments

    The calibration process of water distribution system models allows for accurate and reliable hydraulic analysis results. Thus, calibration is of utmost importance if adequate operation and maintenance model-based procedures are sought. However, in emerging economies, there is a series of factors that make it more difficult to construct accurate models, including very poor information management, ...

  • Energy efficiency in water distribution systems - A path to an ideal network - AGS experience

    Water utilities’ responsibility to deliver quality and reliable service under a sustainable basis requires an increasingly efficient management and therefore an asset management strategy that ensures high levels of service, safe and reliable drinking-water quality and an appropriate network performance. In Portugal, IAM gave a step forward with a recent Portuguese decree law (Decreto-Lei ...

  • A PSO approach for optimum design of dynamic inversion controller in water distribution systems

    Water distribution systems have become immensely complex due to ever increasing water demand and sporadic availability of water at the sources. Generally, water management issues are handled through human intervention, which naturally leads to incompetent trial and error procedures. Moreover, the non-linear system dynamics and sequential pumping operations involved in the water distribution ...

  • Project Renew: A Regional Approach to the Distribution of Reclaimed Water

    ABSTRACTThe Orlando Utilities Commission (OUC) has been granted a 20-year permit to use the Floridan aquifer as a source of potable water. In addition to providing for the continued use of groundwater, the permit also requires that OUC make use of alternative water supplies. One of the most innovative of the alternative water supply projects is referred to as project RENEW. The OUC Consumptive ...
