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 problem is that the suction side of the pump is not connected to anything. There needs to be a boundary condition (tank or reservoir) on the upstream side of a pump in order for the model to work correctly.

    In your initial description, it sounded like your pumps pull water from a tank, which would indicate that pipes would connect between the pump suction side and the tank like this:
