How should I approach this?

Question

Hi all, 
 
 So I'm working on a unidirectional flow project and I have trouble approaching this project. 
 I've encountered two problems and I don't know how to go about it. 
 1) there's one account and 2 uses (indoor and irrigation), should I combine the two? or should I use one as opposed to the other? 
 2) the other problem is almost the complete opposite, I have two accounts that corresponds to the same address. 
 If anyone could give me a couple pointers that would be greatly appreciated! 
 
 Thank you so much in advance!

Hello Yoko, 
 
 Yes,, you can have separate customer elements for these two purposes of indoor use and irrigation use, which will connect to the same junction meaning adding demands to one junction only. About billing ID, two customer meters can have one unique ID, I tested this in the latest version and it does accept same billing ID for two customer element. 
 If you have several customer accounts on the same address then those will shown at the same spot since their location is same. 
 
 Here is detailed information about customer elements, for your reference.

Hello Huy, 
 
 Whether to combine the indoor flows and irrigation flows into a single model, would depend upon how your irrigation system is set, is it sprinkler system? do you want to use pressure dependent demands for irrigation? 
 Could you please elaborate about two accounts that correspond to same address? Does it mean you are having two water sources feeding the same area and how to model that?

Hello Huy, 
 You mentioned that this is for a "unidirectional flow" project - are you referring to a unidirectional flushing simulation, in which one or more hydrants are opened along with closure of one or more valves? 
 Your questions seem to be about demand loading - are you concerned about accurate placement of demands such that pipe velocities are accurate during a unidirectional flushing event? 
 Regarding the two accounts corresponding to the same address - what is your specific concern about this? I assume that there are two separate water meters at this particular address, which supply different purposes for whomever resides at the address. For demand loading purposes, it sounds like you could model this as two separate Customer meter elements with the corresponding metered flow, connected to a single junction at the location where the customer ties in to the water main. Or, you could model them as two separate demand entries on that junction.
