because consumer demand varies throughout the day, day of the week and time of year.

00:18

Demand categories provide 24 hour profiles for a particular type of consumer.

00:24

Typically,

00:25

consumers belonging to a particular demand

00:27

category will have similar demand patterns

00:31

to define demand patterns.

00:32

You can use the demand diagram which contains categories that

00:36

define the demand pattern for an individual type of consumer.

00:40

In this example,

00:41

you will assign a demand category and specific consumption

00:44

properties to a node for a planned housing development.

00:48

Before starting, you will need to copy session five dot WPT into your database.

00:54

Open the bridge net GEO plan

00:56

and work within a new scenario that has a new node linked to the existing network

01:02

to assign a demand category to the newly created node.

01:05

The demand diagram needs to be open

01:08

from the database model group window,

01:10

expand demand diagram group and then select Bridgetown ad A W

01:17

the demand diagram dialog opens

01:21

next open the properties panel for

01:23

the node representing the future housing development

01:27

from the toolbar, select properties. And then in the GEO plan select the new node

01:34

from the properties panel under demand.

01:36

Notice the demand by category option

01:39

select more which is the ellipsis button to open the demand by category dialogue.

01:45

A demand category can be defined in one of three ways.

01:49

In

01:49

this example, you will define demand per property

01:53

from the demand by category dialogue, expand the demand category dropdown.

01:58

This list is populated by the categories contained in the

02:01

current demand diagram which is running in the background.

02:06

Select domestic

02:08

then expand the category type drop down and select property

02:13

in the number of properties field.

02:15

Enter an estimation for a number of properties within the category such as 100

02:22

in the specific consumption field.

02:23

Enter an estimation of consumption for each property in the category such as 400

02:30

click OK.

02:32

Notice in the GEO plan,

02:33

the node shape updates to a star which represents the new allocation of demand.

02:39

After allocating demand to the node,

02:41

you can then verify the scenario and commit the changes to the master database

02:46

to commit the changes from the model group

02:49

window under session five right click bridge net.

02:52

And from the shortcut menu, select commit changes to master database

02:58

in the comments field. Enter a description of the changes you made and then click OK

03:04

to run accurate simulation results.

03:06

It is critical to allocate appropriate demand

03:08

categories to objects within a model group.

Step-by-step Guide

In InfoWorks WS Pro, allocating demand to nodes throughout a water supply network is crucial to the accuracy of simulations. Because consumer demand varies by time of day, day of the week, and time of year, demand categories provide 24-hour profiles for a particular type of consumer.

The demand diagram contains categories that define the demand pattern for an individual type of consumer. This example assigns a demand category and specific consumption properties to a node for a planned housing development.

  1. Copy Session 5.wspt into your Database.
  2. From the Model Group window, drag-and-drop BridgeNet into the workspace to open the GeoPlan.
  3. In the Scenarios toolbar, expand the Select scenario drop-down.
  4. Select a new scenario that has a new node linked to the existing network.

To open the Demand Diagram window, which must be open:

  1. From the Model Group window, expand Demand Diagram Group.
  2. Select BridgeTown ADAW.

The InfoWorks WS Pro interface, Model Group window, with BridgeTown ADAW selected; and in the workspace, the network GeoPlan open to the Housing Development scenario.

The Demand Diagram window, with tables of values and graphs for a particular demand category.

To define the demand category for the node representing the future housing development:

  1. From the Tools toolbar, select Properties.
  2. In the GeoPlan, select the new node.

The Tools toolbar with Properties selected, and the GeoPlan with the new node selected, both highlighted in red.

  1. From the Properties panel, in the Demand By Category option, select More (…).

The Properties panel with More (…) selected next to Demand By Category.

Note: A demand category can be defined in one of three ways. This example defines demand per property.

  1. In the Demand By Category dialog box, expand the Demand Category drop-down and select DOMESTIC.

Note: This list is populated by the categories contained in the current Demand Diagram, which is running in the background.

  1. Expand the Category Type drop-down and select Property.
  2. In the Number Of Properties field, enter an estimation of the number of properties in the category, such as “100”.
  3. In the Specific Consumption field, enter an estimation of consumption for each property, such as “400”.
  4. Click OK.

The Demand By Category dialog box with values entered for the demand category and OK selected.

Notice in the GeoPlan, the node shape updates to a star, representing the new allocation of demand.

The GeoPlan with the node shape updated to a star to represent the new allocation of demand.

To verify the scenario and commit the changes to the database:

  1. In the Model Group window, under Session 05, right-click BridgeNet and select Commit changes to database.

In the Model Group window, the BridgeNet shortcut menu with Commit changes to database selected.

  1. In the Commit changes to database dialog box, under Comments, enter a description of changes made.
  2. Click OK.

IMPORTANT: To run accurate simulation models, it is critical to allocate appropriate demand categories to objects within a model group.
