The demand allocator.

00:05

In info water pro allows for seven distinct allocation

00:08

methodologies to be used for the allocation process.

00:12

In this exercise, you allocate demands using the closest pipe method.

00:16

The closest pipe method works with billing meter data

00:20

for each of the meters.

00:22

The closest pipe is first located with advanced search algorithms.

00:26

The meter demands are then assigned to either the closest

00:29

upstream or downstream nodes for each of the selected pipes

00:33

to begin.

00:34

Double click the desired project dot AP Rx file to open Argi

00:38

Pro.

00:40

Once the project starts,

00:41

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

00:46

in the project panel, click initialize

00:50

start by adding the meter sales data to the arc G

00:52

I S pro contents panel if needed

00:55

from the arc G

00:56

S ribbon on the map tab

00:58

in the layer panel, click add data,

01:03

navigate to and double click the dot GDB file for this exercise,

01:08

select the meter sales shape file and then click OK to add it to the table of contents.

01:14

If you do not want it visible in the map,

01:16

then you can turn off the meter sales layer in the contents panel

01:21

on the info water pro ribbon

01:23

in the allocator panel, click allocation manager

01:28

in the allocation method group, select closest pipe

01:33

in the meter configuration group expand the meter layer dropdown.

01:38

The layers available in this list include all point layers in the argi

01:42

pro contents that are not info water pro layers

01:46

select the meter sales layer.

01:48

If you cannot see the full file path in the field,

01:51

you can hover the cursor over the field or drag the

01:54

edge of the demand allocation manager window to expand it.

01:58

Next in the meter configuration group, expand the demand field dropdown,

02:03

scroll down and select DMDD.

02:07

This signifies that the D MD field in your

02:09

meter layer contains the demands to assign to your model

02:14

in the pipe ID field group.

02:16

Click new field and then in the new field

02:18

pop up specify HX underscore pipe as the new field

02:23

and then click OK.

02:26

This populates the idea of the pipe. Each meter is assigned to.

02:30

If you do not see the HX pipe fields already populated as the pipe ID field,

02:35

you can expand the dropdown and select it from the list.

02:39

Next on the allocation tab set the allocation scaling factor to one

02:45

for the meter assign option.

02:47

You can select either evenly divided or distance weighted.

02:51

If you choose evenly divided,

02:53

then the total demands determined from all meters

02:55

assigned to a particular pipe will be divided

02:57

by two and assigned equally to both the

02:60

upstream and downstream junctions of the pipe.

03:03

If you choose distance weighted,

03:05

then a geometric analysis is conducted for each meter assigned

03:09

demands are then divided between two junction nodes according to their weighting.

03:13

For example, if a meter has a 10 GPM demand and is three quarters of the way down a pipe,

03:19

then one quarter of 10 GPM will go to one junction

03:22

while three quarters of 10 G PM will go to the other

03:26

for this exercise, select distance weighted and then click allocate demand.

03:31

These calculations can take a longer time to assign the

03:34

demands to junctions due to the meter assign option.

03:37

However, it is more accurate than the closest junction method

03:43

in the allocation report and water duty calculator window that appears you

03:47

can view the results of this allocation using the closest pipe method

03:52

when you are finished.

03:53

Click OK to close the allocation report and water duty calculator window

03:57

then click close to exit the demand allocation manager.

Step-by-step:

The Demand Allocator in InfoWater Pro allows for seven distinct allocation methodologies to be used for the allocation process. The closest pipe method works with billing meter data. For each of the meters, the closest pipe is first located with advanced search algorithms. The meter demands are then assigned to either the closest upstream or downstream nodes for each of the selected pipes.

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

To add the meter sales data necessary for the allocation:

  1. From the ArcGIS ribbon, Map tab, Layer panel, click Add Data.
  2. Navigate to and double-click the .gdb file for this exercise.
  3. Select the Meter_Sales shapefile.
  4. Click OK to add it to the table of contents.
    The Add Data dialog box, with the Meter_Sales shapefile highlighted.
  5. On the ribbon, InfoWater Pro tab, Allocator panel, click Allocation Manager.

To set up the allocation in the Demand Allocation Manager:

  1. In the Allocation Method group, select Closest Pipe.
  2. In the Meter Configuration group, expand the Meter Layer drop-down.
  3. Select the Meter_Sales layer added earlier. (If you cannot see the full file path in the field, hover the cursor over the field, or drag the edge of the Demand Allocation Manager window to expand it.)
  4. In the Meter Configuration group, expand the Demand Field drop-down.
  5. Scroll down and select DMD. This signifies that the DMD field in the meter layer contains the demands to assign to the model.
  6. In the Pipe ID Field group, click New Field.
  7. In the New Field popup, specify HX_PIPE as the new field.
  8. Click OK. This populates the ID of the pipe each meter is assigned to.
  9. Expand the Pipe ID Field drop-down and select HX_PIPE, if it is not already selected.
  10. Set the Allocation Scaling Factor to 1.
  11. For the Meter Assign Option, select Distance-Weighted. A geometric analysis is conducted for each meter assigned. Demands are then divided between two junction nodes according to their weighting.
    The Demand Allocation Manager, with settings for this Closest Pipe allocation.
  12. Click Allocate Demand.
  13. Wait for the Allocation Report & Water Duty Calculator window to appear after a few minutes.

Note: These calculations can take a longer time to assign the demands to junctions due to the meter assign option; however, it is more accurate than the Closest Junction method.

  1. In the Allocation Report & Water Duty Calculator window that appears, review the results of this allocation using the closest pipe method.
    The Allocation Report & Water Duty Calculator window displaying the results of Closest Pipe allocation.
  2. When finished, click OK to close the Allocation Report & Water Duty Calculator window.
  3. Click Close to exit the Demand Allocation Manager.
