I have been asked to design a non-pot system for a golf course development. They need a design that places 3/4" meters in the back end of 292 lots so that the owners will have access for irrigation. They have designed and installed the golf course irrigation system and have left irrigation stubs at various point coming off the mainline for the golf course. Each stub has a flow rate and size of pipe stub. As I see it, has anybody had experience with this sort of design. I know how to do it on paper, but what is the best way to approach by using FC Cad irrigation.

Robin,
As I understand it, you have 292 Meters stubbing off of the mainline. I imagine your work is ending there, you are showing just the 3/4" meter, and your work is to demonstrate that the design can sufficiently provide the requisite pressure and flow to operate said meters. In this case, you would not place them as a POC in Land F/X -- they are not a Source of water, but are instead a demand. So this is why you would add a Cap to the project under Auxiliary equipment, and place that as your individual meters. Then when you size the mainline, there is still your one true POC, which is the source, and the system will validate it can supply the various caps.

Robin,
From the sound of it, you would place the 292 meters as Caps, instead of meters. In this instance, you want them to act as a demand on the system, not a source. You could place just one, and enter the PSI and GPM demands for it. Then, copy it around the site. And then lastly, pipe to them all.

Thank you Jeremiah! As long as each stub from the golf course mainline is treated has a POC, it will size the mainline or submain in this case? Do I need to make each POC and the mainline and meters a separate work area?
