  • 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 ...

  • 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, ...

  • 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 ...

  • 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 ...

  • The impact of diurnal water use patterns, demand management and rainwater tanks on water supply network design

    The traditional use of long-term average consumption records and “peak factors” to determine water network design criteria does not account for allotment-scale diurnal water use patterns which impact upon the dynamics of water distribution systems. The diversity of allotment-scale diurnal water use patterns directly impacts on network dynamics. Demand management and rainwater tanks are likely to ...

  • 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 ...

  • 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 ...

  • 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 ...

  • The Bullwhip effect in water demand management: taming it through an artificial neural networks-based system

    The Bullwhip effect (BE) refers to the amplification of the variance of orders and inventories along the supply chain as they move away from the customer. This is considered as the main cause of inefficiencies in the management of a traditional supply chain. However, the BE is not relevant in the classic system of water distribution, based on long-term supply management. Nevertheless, current ...

  • Dual-use value of network partitioning for water system management and protection from malicious contamination

    This paper considers the introduction of a contaminant into a water supply system using a backflow attack. The recent development of techniques for water network sectorization, aimed at improving the management of water systems, is also an efficient way to protect networks from intentional contamination and to reduce the risk of the dangerous effects of network contamination. Users can be ...

  • 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 ...

  • Short-term demand forecast using a bank of neural network models trained using genetic algorithms for the optimal management of drinking water networks

    Efficient management of a drinking water network reduces the economic costs related to water production and transport (pumping). Model predictive control (MPC) is nowadays a quite well-accepted approach for the efficient management of the water networks because it allows formulating the control problem in terms of the optimization of the economic costs. Therefore, short-term forecasts are a ...

  • Crumbling Concrete Water Networks Linked to Common Water Treatment Additive

    Concrete distribution and sewer networks are being corroded at an alarming rate partly because of a commonly used additive in the domestic drinking water and wastewater treatment process according to published reports in the journal Science. In countries throughout the world from industrialized nations like Australia and the USA to developing nations like Colombia, Ghana and the Philippines, the ...

  • 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 ...

  • 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 ...

  • New indices for reliability assessment of water distribution networks

    This paper presents new indices to evaluate the reliability of water distribution networks (WDNs) usable in the design, planning and management of these networks. Since the pressure-driven analysis (PDA) of WDNs produces more accurate results than the demand-driven analysis, the new indices are proposed based on the PDA. In the proposed measures, nodal pressures, nodal available discharges and ...
