Multilpe Water Meter Connections Tutorial

Henry,
Unfortunately that is the only page that we have on running multiple water meters. This is definitely a tricky subject and there are all kinds of different scenarios that could possibly come up. We are doing our best to document each scenario as they come up.

It might be helpful for you (and us) to send in a tech support ticket so we could reach out to you personally and walk through your scenario to see what the best route to take would be. In turn, we can update the documentation to expand on the new scenario so it is available to all.

How to submit a tech support ticket

Hi , I have reversed situation. I am working on a mid scale complex with 9 flow zones ( 9 buildings with surrounding landscape) and one POC (pump station conected to reclaimed water from WWTP- Waste Water Treatment Plant). For each building /flow zone , I need to place water meter. How will land f/x work with this? Do I need to anticipate some moves or steps to make this work (in terms of calculating flow, critical analysis, drawing and sizeing mainline ) . System will be centralized , so I do not expect problems on watering schedules and valve shedules ... Any tips or videos on this?

Thank you

Naturalist,
If you have one POC that is feeding the entire system, then that is all you really need to focus on. The main POC is going to hold all of what is available. The sub meters at each building is more of another piece of equipment that should be called out, but not what immediately dictates what the demands of what each building will be sized to.

You have a few options here:
1- Keep the main POC as the single source- Size the entire system with multiple valves at a time, even picking which valves run together for worst case scenario. You could even integrate Flow Zones in and around each of the buildings to keep the flows a bit lower and the main trunk of mainline feeding all buildings a bit higher.
2-Add 9 Points of Connection to your Source Data and input the exact available pressure and flow for each. Place each POC where they would essentially be tied into the main mainline, and size each POC to get the demands of each building.

If you are required to the size the mainline back to the Original POC, you can take the Critical Analysis of each POC, place Caps at each of the 9 POC's and input the demands of each, and pipe the mainline from Caps back to the original POC.

Below are a few links to items referenced above. We are also happy to chat more if you would like to send in a technical support ticket.

2-Add 9 Points of Connection to your Source Data and input the exact available pressure and flow for each. Place each POC where they would essentially be tied into the main mainline, and size each POC to get the demands of each building.

I have a quastion for option 2: If i choose this option I will have total of 10 POC's (1 main POC + 9 "sub" POC's),but the problem is placing caps , because i will need all 9 sub POC's to have free flow in order to size mainline from them to the solenoid valves ? And also, this will be one centralized system, everything will be in one drawing. It is not phased design giving just some connection to Phase 1 , 2 or Phase 9, everything should work together in the same design.

Maybe, option 1 is better solution for this case, as it looks like one design with just water meters and limited flow for different buildings/flow zones, and only one POC which will basically be the pump station ?

Naturalist,
It really just comes down to what information you want the system to generate. If you want to know the exact demands at each building, where it would tie into main feeder line, then you would want to place a POC at each of the buildings. This is going to give you the ability to run a unique Critical Analysis for each building so you know worst case in each area.

Further, if you then want to size the mainline back to the beginning POC, you can place caps (plot or non plot versions as shown in the Power tip I listed previously) next to each POC, and enter the critical analysis values of each POC into each Cap. You can then pipe mainline from the Caps to the main POC (not piping to each buildings POC).

If you just need to know on an overall scale, that the main mainline can handle the overall sizing of the system, then you can place all valves as needed and connect into the same mainline that goes back to the main POC. Sizing this single POC will still give you a Critical Analysis, but not building specific.

Keep in mind that either of these options can be done in a single drawing, and does not have to be done as a phased design.

I hope this is a little more clear, but if not, please reach out and I am happy to discuss things in more depth with you.
