Demands are relevant at a range of scales

and can be modelled in several different simulation modes

scenarios, Urban Developer Scenarios are simulated

to generate a database of average water demands for a range of dwelling and end-use types. The average demand databases are used by Urban Water User nodes in a Source Scenario to calculate demands for a suburb or region, based on the distribution of dwelling types and end-uses in that region

Workflow
The workflow for integrating urban demand models with a Source Scenario proceeds as follows:
Urban Scenario Configuration
- Construct one or more Urban Scenarios, called “demand model templates”, using Behavioural Water Use nodes to represent specific dwelling types, including water supply and discharge configurations, and climate conditions. The Urban Developer scenarios also define a range of different appliance types for each of the end-use categories (showers, washing machines, dishwashers, etc). For example, the user might construct four separate Urban Scenarios representing the following dwelling types (e.g. Figure 1):
- detached dwelling
- detached dwelling with rainwater tank
- semi-detached
- apartments
- Simulate each demand model template (Urban Scenario) using the Urban Combination Configuration to generate a database containing the average water demand for every combination of occupancy and end usage type for the given climate.
Figure 1. Example Urban Scenario (demand model template) representing a detached dwelling with a rainwater tank.
Refer to Running Urban Scenarios for further information on configuring and running an Urban Combination Configuration.
Source Scenario Configuration
The results of Urban Combination simulations can be used by Water User nodes in
...
.
Note that, the Source Scenario should be simulated under the same climate conditions as the Urban Scenarios to ensure that water supplies and demands are consistent.
Figure 2 illustrates the methodology for simulating the urban demand models within a Source Scenario.
