1Proven Application2URG ENTPIPEREP AIRCase study: Saudi ArabiaPipeline simulators show how pressure transients are causing leaks and burstsby modelling and tracking the transients entering DMA’s from Transmission Mainsthroughout Saudi Arabia. Several real-time simulators were installed throughoutSaudi Arabia, including Al-Lith and NEOM. The simulators include a proven leakdetection capability and a pipeline management function.Pressure logging was also provided on-site to locate blockages in the pipelinesand a training simulator to help operators understand and manage the pipelines.Any operational procedures can be tested out first on the Digital Twin to show thepressure transients (surge / waterhammer) caused by an operational change to givetrue confidence to operators.34Case study: Dubai Water Supply NetworkVariSim Delta is powered byVariSim which is a uniqueindustry leading, real-timesimulator is installed in theDubai Water Control Centreand includes the completewater distribution networkof Dubai.It is driven by hundredsof pressure and flowsensors across the citywhich update every fourseconds to give a highlyaccurate picture of thelive operation of thenetwork in the SCADAcontrol room. It is quitesimply the most advancedreal-time water networksimulator in the world.The hydraulic simulatorshows the pressure, flow,valve position and controlsystem status at everypoint in the water supplynetwork throughout Dubai.The DEWA HydraulicManagement System (HMS)includes all control systemsand is used for manydifferent functions,including water balancing ,event replay and training .The data flow from thepipelines, reservoirs andtreatment plants into thecontrol centre is trulyimpressive. Around onemillion data points areprocessed by theVariSim hydraulicsimulator every minuteand this does not includeany high-speed pressuretransient data.Case study:Qatar WaterDistribution SystemSo why choose Morrison Water Services?Our experience and flexibility enables us to meetthe challenges of an ever-evolving market.We engage early to understand our clients’ business plan.Our people bring commitment, innovation, teamwork andaccountability to achieve successful, long-term partnerships.Morrison Water Services understands the demands of theregulated water sector, and has a long history and significantexperience in the full service delivery of water and wastewaterservices.
