Merging Pressure Zones

00:04

After running a pressure zone manager, trace and analysis,

00:07

you can merge pressure zones in your model

00:10

to begin

00:11

double click the desired project dot

00:13

X file to open

00:15

Agis Pro.

00:16

Once the project starts,

00:18

click the info water pro tab to open the info water pro ribbon

00:22

in the project panel, click initialize

00:26

in a previous PCM run. It was discovered that PGM six should be merged with PGM three.

00:33

In this exercise, you will merge these two zones into a single pressure zone

00:38

on the info water pro ribbon in the project panel, click apps

00:44

then double click P Z M

00:47

in the pressure zone manager, click options

00:52

in the PCM options, dialogue under zone id set, the next ID counter to one

00:58

then click OK.

01:00

This is because the PC M tool has been run prior to this exercise.

01:05

However, if you just started, you would start with PC M seven rather than PC M one.

01:11

So make sure you reset this any time you rerun the PZ M tool.

01:15

Click new to start the pressure zone wizard

01:19

on the first page next to store the elements, zone id in this field, enter zone

01:24

id

01:26

for output time. Enter zero hours.

01:29

Click next

01:32

for step one in the definition of trace area group,

01:35

select no user defined boundary pipes.

01:37

Then click next

01:40

on the step two page.

01:41

You can define intra zone elements for the PC M to ignore them as zone delineates

01:46

but still treat them like junctions in the simulation.

01:49

Click add row

01:51

in the new row, expand the type, drop down and set it to pump.

01:56

Then click select element

01:59

in the model zoom in and select pump P 100

02:04

pump P 100 is the north pump connected to W T P 100 that was included in PCM six.

02:10

In the original analysis,

02:12

you can also type in the pump id rather than manually selecting it from the map.

02:17

Click add row again and repeat these steps to add pump P 120 to a new row.

02:23

Now these pumps will be included in the closest pressure zone.

02:27

Click next

02:28

for step three, no boundary pipe elements are a user to find. So click next

02:34

on the step four page,

02:35

you can see the customized zone information for the six

02:38

start nodes that was created during the earlier run.

02:41

Click clear all to remove this information and then click next

02:46

on the trace and analyze page. Click run

02:50

the PCM performs a trace analysis to identify pressure zones in the model.

02:54

With the updated information you provided,

02:57

you can see that five pressure zones are created

03:00

PCM. One to PCM five

03:03

PZ M six no longer exists and is now part of PZ three.

03:08

Click finish to close the wizard and return to the pressure zone manager

03:13

in the pressure zone manager.

03:15

Click the cell above the zone list to select all the zones and then click show zone,

03:21

move the pressure zone manager window to the side

03:23

and view the map with all pressure zones,

03:25

color coded,

03:27

click close to exit the pressure zone manager.

Video quiz

Required for course completion

When merging pressure zones using the Pressure Zone Manager, on the page, “Step 2 – Designate Intra-Zone Elements” you must list which of the following?

(Select one)
Select an answer

1/1 questions left unanswered

Step-by-step:

After running a Pressure Zone Manager trace and analysis, you can merge pressure zones in your model.

  1. Open the appropriate .aprx file in ArcGIS Pro.
  2. From the ribbon, InfoWater Pro tab, Project panel, click Initialize.

In a previous PZM run, it was discovered that PZM6 should be merged with PZM3. To merge these two zones into a single pressure zone:

  1. On the ribbon, InfoWater Pro tab, Project panel, click Apps.
  2. Double-click PZM.
  3. In the Pressure Zone Manager, click Options.
  4. In the PZM Options dialog box, under Zone ID, set the Next ID Counter to 1.
  5. Click OK.
    The PZM Options dialog box with Next ID Counter set to 1.

IMPORTANT: Resetting the Next ID Counter is necessary because the PZM tool has been run prior. However, if you just started, you would start with PZM7 rather than PZM1. So, make sure you reset this any time you re-run the PZM tool.

  1. Click New to start the Pressure Zone Wizard.
  2. On the first page, next to Store the element's Zone ID in this field, enter “ZoneID”.
  3. For Output Time, enter 00:00 hrs.
  4. Click Next.
  5. For Step 1, in the Definition of Trace Area group, select No User Defined Boundary Pipes.
  6. Click Next.
  7. On the Step 2 page, users can define intra-zone elements for the PZM to ignore them as zone delineators, but still treat them like junctions in the simulation. Click Add Row.
  8. In the new row, expand the Type drop-down and select Pump.
    The Step 2 page of the PZM Wizard with Pump selected as the Type.
  9. Click Select Element.
  10. In the model, zoom in and select Pump P-100, or type “P-100” into the pump ID field.

Note: Pump P-100 is the north pump connected to WTP100 that was included in PZM6 in the original analysis.

The Network map with Pump P-100 selected.

  1. Click Add Row.
  2. Repeat steps 15 – 17 to add pump P-120 to a new row.

Pumps P-100 and P-120 will now be included in the closest pressure zone.

  1. Click Next.
  2. For Step 3, no boundary pipe elements are user-defined, so click Next.
  3. On the Step 4 page is the customized zone information for the six start nodes that was created during the earlier run. Click Clear All to remove this information.
    Step 4 of the PZM Wizard, showing the color codes and start nodes for each zone ID, with Clear All highlighted.
  4. Click Next.
  5. On the Trace and Analyze page, click Run.

The PZM performs a trace analysis to identify pressure zones in the model with the updated information.

Five pressure zones are created, PZM1 through PZM5. PZM6 no longer exists and is now part of PZM3.

  1. Click Finish to close the wizard and return to the Pressure Zone Manager.
    The Pressure Zone Identification and Analysis page of the PZM, displaying the five pressure zones
  2. In the Pressure Zone Manager, click the cell above the zone list to select all the zones.
  3. Click Show Zone.
  4. Move the Pressure Zone Manager window to the side and view the map with all 5 pressure zones color-coded.
    Pressure Zone Manager with all zones selected and Show Zone highlighted with resulting color-coded network map
  5. Click Close to exit the Pressure Zone Manager.
