pump curve

M
Offline

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.

    Hi M,

    Take a look at Example5.wtg which is delivered with the product.  It can be found in C:\Program Files (x86)\Bentley\WaterCAD\Samples.  It has a pump station (2 pumps) pulling from a reservoir.

    Please let me know if this does not contain the information you're looking for.

    Thank-you,
    Larry

    I attached a copy of my model, I just want to make sure I drew the pump and tank correctly. I was not entirely sure what I should be using for the elevation of the pumps and the elevation of the downstream junction (J-121)? thanks for the help. Also when I draw my tank, does it have to be placed in the actual location on site in terms of the water distribution network?

    "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.
