  • Senerio creation

    In my network there are total 4 tanks, I want to test the network in case 2 of 4 tanks are not working ( water is being supplied by only 2 tanks) to see how it affect the network. Till now I am using controls to simulate this, Is there any way to achieve…
  • What is the best method for adding new pipelines to existing models whose diameters are frozen? The intent is to minimize design errors and meet requirement of minimum residual head at all nodes

    We have executed distribution network models from about 20 tanks to 20 independent service areas for a client. Pipelines are laid. Now client wants to extend all the networks, by adding 10-15% of pipelines in all models. I have dxf files containing…
  • Watergems: I am trying to add new pipes and junctions from dxf file. But junction elevations are not getting reflected after modelbuilder. I am mapping elevation to "elevation". Generally this method works. But it is not working when i am trying

    My surveyor gives me point elevations in dxf file, situated along centerline of pipeline. When I build my model in Watergems, i usually map "elevation" attribute in junction to elevation field in AutoCAD file. This ensures that i get accurate point elevations…
  • stop and start of pump, based on level of tank

    I want to create a network in which, pump fill Tank from empty to full and then stop; and pump start again when tank is empty(or at a certain level). when the pump is running it should be running on max capacity. In my model, tank level fluctuate…
  • SewerGEMS - some questions about using the program

  • I am completing a calibration based on a hydrant flow test. Can't fathom a smaller HGL difference than what elevations indicate.

    I am completing a calibration based on a hydrant flow test. I have two hydrants 675' elev and 632' elev. So 43' of elevation difference, and 700 feet apart through a 16" water pipe. The static measured by the fire test guy shows only 10 psi difference…
