1. Creating an Urban Scenario in Source


The Urban Developer Plugin to Source allows the Source user to add an Urban Developer scenario. 

Figure 1. Create an Urban Developer scenario 

This section of the documentation will describe how to set up the node components of an Urban Developer scenario (Figure 2.) and how to configure the interactions between these nodes.

Figure 2. Overview of the node components of an Urban Developer scenario

The urban demand is represented by a Water Use node (Figure 3.). Urban Developer offers two methods for simulating the water use at a water use node, either as:

  • an Average daily model, or
  • a Behavioural model

If relevant, supply can be supplemented by water from a Tank attached to a Roof, represented as two further nodes (Figure 3.) which can be configured.

Figure 3. Urban scenario water use nodes

Urban Developer represents urban demand at the node by simulating individual end-uses at the household level. Currently represented end-uses include:

  • outdoor/variable;
  • shower;
  • washing machine;
  • toilets and
  • indoor hand taps and dishwashers

End-uses such as baths and leaks are not modelled explicitly, but can be lumped with the outdoor/variable end-use. Separating demand into individual end-uses provides the user with the flexibility to apply different supply sources for each of the types of end-use.
