  • The Need for a Total View of Water Networks

    The water industry is not short of software offerings, and so the arguments in favour of yet another software program had better be very good indeed. In this article we examine how one very significant community of users – operations managers, engineers and planners - have largely had their specific needs overlooked; we identify the type of system needed to fulfil their requirements and the ...

  • 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 ...

  • Impact of water source management practices in residential areas on sewer networks – a review

    Prolonged drought which has occurred everywhere around the world has caused water shortages, leading many countries to consider more sustainable practices, which are called source management practices (SMPs) to ensure water availability for the future. SMPs include the practices of water use reduction, potable water substitution and wastewater volume reduction such as water demand management, ...

  • 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 ...

  • New development of pipe-network management in Kobe City

    Distribution pipelines now require a lot of maintenance and mass renewal. We need to determine measures to maintain water quality and to carry out reconstruction of the pipeline system. In addition, the mass retirement of engineers also provides us with a serious challenge on how to transfer their knowledge and skill. In 2008 Kobe City established Kobe Waterworks Vision 2017, in which plans have ...

  • InfoWorks WS helps manage network shutdowns

    InfoWorks WS includes enhanced tools for analyzing the shutdown of parts of a water supply network. The new Shutdown Simulation analysis enables efficient management of emergencies and planning of repairs. Applications range from dealing with pollution incidents to coping with broken pipes. The latest developments make it easier than ever for operators to decide how to minimize the ...

  • Managing Metallic Pipeline Networks In A Sustainable Manner

    In North America, the material and size of pipes that make up water and sewer networks range widely. Because these pipeline systems are so complex, it requires a strategic approach based on risk and real data for effective long-term management. Historically, however, it has been challenging to gather real data that can shape defensive capital decisions for an entire system. The assessment of ...

  • Information Network Topologies for Enhanced Local Adaptive Management

    A land-use-change simulation model (LEAM) and a non-point-source (NPS) water quality model (L-THIA) were closely coupled as LEAMwq in order to determine the long-term implications of various degree of urbanization on NPS total nitrogen (TN), total suspended particles (TSP), and total phosphorus (TP) loads. A future land-use projection in the St. Louis metropolitan area from 2005 to 2030 using ...

  • Adaptation of sewer networks using integrated rehabilitation management

    The urban water structure is aging and in need of rehabilitation. Further, the need to address future challenges (climate change, urban development) also arise lines. This study investigates if it is possible to combine rehabilitation and adaptation measures. To do so, we combined an urban development model, an urban drainage model and a rehabilitation model. A case study of a medium-sized ...

  • The Application of Network Modeling in Drought Management: Reflections on the AWWA Drought Management Handbook

    Introduction Water and life are synonymous. Communities expect to be protected from floods, to have a reliable and safe water supply, to be able to swim and fish in rivers and lakes. Stakeholders who share water ultimately compete for that water, with conflicts becoming more critical during periods of prolonged drought, when there is not enough water to go around and rationing is enforced. ...

  • Flexible investment planning for water distribution networks

    The present work focuses on the planning of water distribution networks (WDNs). The research proposes an innovative strategy which aims at helping water managers formulate flexible investment plans while allowing for adaptive management under the increasing unawareness of medium–long term planning. This innovative strategy differs from existing strategies accounting for flexibility in WDN ...

  • Insertable Valve Network Provides OngoingSolution to Water Loss

    Orange Cove, CA - As the only city in Fresno County that is completely dependent on surface water, the City of Orange Cove had 40% unaccounted for water loss when Bill Little, former City Manager returned to Orange Cove to address the community’s growing water problems... “Our goal is to reduce unaccounted for water loss in Orange Cove down to 3% - 5%,” explained Little. “In a city with an old ...

  • Adaptive water distribution networks with dynamically reconfigurable topology

    This paper presents a novel concept of adaptive water distribution networks with dynamically reconfigurable topology for optimal pressure control, leakage management and improved system resilience. The implementation of District Meter Areas (DMAs) has greatly assisted water utilities in reducing leakage. DMAs segregate water networks into small areas, the flow in and out of each area is ...

  • The Effects of Intermittent Supply on Water Distribution Networks

    The world’s population is increasing at a tremendous rate, the world’s renewable water resources are reducing rapidly, the gap between supply and demand is widening with urbanisation and climate change making it even wider. This paper reviews how the Water Board of Lemesos, Cyprus, a water utility with a proven history of managing extremely well its distribution network, was forced ...

  • Component-holistic condition assessment of water distribution networks

    The work presented herein presents an expanded methodology for imprinting the condition of an urban water distribution network (WDN). Even though the majority of past research efforts related to WDNs deal with water mains (WMs), only a small part of the research studies have considered house connections (HCs) in the analysis and very few researchers have examined how the failure of pipe ...
