  • Input Data of Pump Q & H is not matching with Output Results

    Hi, We are using the Water GEMS V8i (Select Series 5). In one of our project, we are checking the adequacy of existing transmission main with existing pumps. In Water Gems, We have modeled the pipeline & pumps as per existing data like Pump Flow & Head…
  • System Head Curve Using PPD

    I am having some complications in generating a system head curve that I am confident in. Let me explain the scenario. I have a model of a fairly small system (200 ish users) and had modeled the system using a PPD analysis since I don't have any reservoirs…
