    Hi all, I was wondering if someone can suggest how I can arrange and simulate private pump stations in my network. I have a relatively small WDN of 505 households and which has been skeletonized to 30 nodes. A brief survey of the area found that about…

    Amine, A typical-looking system head curve cannot be generated in this condition because the operating point of the pump will always be the sum of the downstream demands. A range of flows cannot be tested. For item #1 - the pump will need…
