  • Water Distribution System Audit

    In April 2007, a site survey of a spa outside of Paris, France, was jointly performed by LuminUltra Technologies Ltd. and AQUA-tools. The spa utilizes untreated mineral water (from ground wells) in its daily operation. The source water is distributed to 40+ stations for therapeutic purposes. One week prior to the site audit, two stations had tested positive for pathogenic organisms in the ...

  • ´More Stations. More Data. Better Forecasts.´ – the NYS Mesonet

    “More Stations. More Data. Better Forecasts.” – that’s the slogan of New York State Mesonet. The weather observation network consists of a total of 125 weather stations all over the state of New York and Lufft was selected as one of the vendors to support them in capturing the data. All 125 of the weathers stations have the standard instrumentation suite. Of those 125, 17 ...

  • Water Distribution System Security Monitoring

    A water security instrument essentially needs to be able to detect potential contaminants in drinking water. Since a significant number of potential chemical contaminants are organic in nature, a water security monitoring instrument that can detect organic matter in water is perfect for this application. Real Tech has developed an instrument specifically designed for water security ...

  • A history of water distribution systems and their optimisation

    Water distribution systems have a very long and rich history dating back to the third millennium B.C. Advances in water supply and distribution were followed in parallel by discoveries and inventions in other related fields. Therefore, it is the aim of this paper to review both the history of water distribution systems and those related fields in order to present a coherent summary of the ...

  • 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 ...

  • 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 ...

  • Assessment of metrics for resilient design of water distribution networks

    Water distribution networks (WDNs) play a crucial role in the well-being of human populations and economic prosperity. It is essential that they cope with abnormal operating conditions and recover functionality quickly. Traditionally, WDNs are designed using cost and reliability objectives, but there is a lack of consensus on the definition and quantification of reliability which typically is a ...

  • 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 ...

  • Review of rehabilitation strategies for water distribution pipes

    Effective rehabilitation strategies for water pipes play a very important role in both sustaining the reliability of water distribution systems and reducing costs. Pipe breakage prediction models provide a platform for effective rehabilitation strategies. The strength of the rehabilitation strategies is just an extension to those predictive models. There are different techniques and methods for ...

  • Analysis of flushing-path effects in water-distribution networks

    The unidirectional and conventional flushing methods are compared in this study and the water amount and flow velocity at junctions within an EPANET water distribution network are compared. In the unidirectional method, the necessary flow and water pressure for the minimum flow velocity for flushing become greater when pipe diameter exceeds a certain value. Therefore, the maximum length of ...

  • Guidelines for transient analysis in water transmission and distribution systems

    All water systems leak, and many supply systems do so considerably, with water losses typically of approximately 20% of the water production. The IWA Water Loss Task Force aims for a significant reduction of annual water losses by drafting documents to assist practitioners and others to prevent, monitor and mitigate water losses in water transmission and distribution systems. One of the causes of ...

  • 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 ...

  • Study on failure rate analysis for water distribution pipelines

    Many of the waterworks facilities in Japan were constructed during the rapid economic growth period. Today, the deterioration and renovation of these aged facilities have become a pressing issue. There are approximately 600,000 km worth of water pipelines laid out across Japan, accounting for about 70% of the nation's water-related assets (totalling ¥40 trillion). To provide water that is safe to ...

  • Water distribution network simulation by optimization approaches

    When a fire-flow condition occurs and a nodal demand is excessive or when a pipe breaks, a water distribution system (WDS) may temporarily become deficient and unable to satisfy all nodal demands. Thus, estimation of the influences of failure conditions on the network is needed. A method for analyzing the hydraulic condition of the network in such a situation is proposed. The method, which is ...

  • Chlorate formation in water distribution systems: a modeling study

    Chlorine-based disinfection agents are known to favor the production of disinfection by-products (DBPs), whose concentrations are restricted by international guidelines to ensure a safe consumption of drinking water. Hence, it is important to understand the behavior of DBPs within water distribution networks (WDNs) to avoid users' exposure to concentrations higher than guideline values. The ...

  • Automated parameter optimization of a water distribution system

    The hydraulic model EPANET was applied and calibrated for the water distribution system (WDS) of La Sirena, Colombia. The Parameter ESTimator (PEST) was used for parameter optimization and sensitivity analysis. Observation data included levels at water storage tanks and pressures at monitoring nodes. Adjustable parameters were grouped into different classes according to two different scenarios ...
