• WaterCAD UDF Flushing simulations velocity

    When running WaterCAD UDF Flushing simulations, when I isolate out a pipe section in the network, why do other pipes in the network still have flow even though there is theoretically no source?
  • Customers meters association in the juctions but considering the closest pipe

    In old WaterGEMS V8i It could associate Customers Meters in the juctions but first checking the closest pipe. I mean, the software get the closest pipe then considering the distance of the start and stop node it get associated with the closest node. In…

  • How to attach an existing junction on an existing pipe line?

    I am working on a model in which many of the junctions are not on the existing pipeline. So, I want to attach the existing junction(which is not attached to the pipeline) to the existing pipeline by not creating a new junction on the pipeline and splitting…
  • Modeling Parallel pipe lines in a gravity network

    Hi, I have a situation where I have to design a gravity network such that I have to utilize the existing pipe in a given network. How to design a parallel pipe in a gravity distribution network. Suppose, the existing pipe has a dia of 100 mm and would…
  • isolation valve position

    Hello, How could I locate an isolation valve at a specific position on a pipe with a schematic drawing? Can an isolation valve replaced by another type of valves in watergems to do the same task?
  • Actual Fire Flow Much Lower than the Ones in the Model

    Dear Community I just had 16 hydrant tests throughout a City of about 30,000 to calibrate the water model. When I compared the fire flows with the model, actual fire flows were lower by 700 gpm on average , 600 gpm on median. At one location, it was…
