pump curve

I am modeling a water distribution network for a town. Currently the town only has one pump station (with three pumps, all designed to deliver 500 gpm each, total of 1500 gpm). The pumps are drawing water from a  nearby water tower (from a different town). Can  someone show me how exactly do I draw my pumps and connect it to the tank, I am a little confused as to how the configuration should look like. I know how to assign pumps curves, it is the layout that I am having trouble understanding.

  • "The pumps are drawing water from a  nearby water tower (from a different town)." Correction, the town is currently not drawing water since it is not existing but it has  one connection point to the nearby town and the town the nearby town has one water tower. In that case should I connect my three pumps to a "fictitious" reservoir? and add a three point pump curve using  hydrant flow tests at that connection point and then draw the storage tank in its actual location?

  • M,

    You can disregard the reservoir unless you have one in the field.  I was just using that model as an example of how to draw your pumps and connect them (as a pump station) to your model.

    You should draw your model as close as possible to the components in the field (and their elevations) so there is no need for a "fictitious" reservoir.  Simply place a storage tank (if that's what you have) rather than a reservoir.

    Hopefully this clears things up a bit.

  • Thanks Larry, your response was extremely helpful. Do you know what elevation I should reference when I am drawing the pump station. 

  • When I relocated the tank to where it is actually placed in the field, I keep getting the  following error: node is not connected to, or is isolated from, a boundary (res or tank)?
