water-saving practices. The discharge from consumption activities can also be apportioned to various water streams.
Restrictions
There are restrictions on which node inputs and outputs you can connect together. See Urban Developer node connection rules.
The Average Water Use node is available for Urban Scenarios only.

Dependencies
| Node Input | Notes |
|---|---|
| Mains supply | Connect to a mains supply node (if available) (Not currently implemented in the Urban Developer Plugin) |
| Tank supply | Connect to a tank node (if available) |
| Alternative supply 1 | Connect to an Alternative supply node (if available) (Not currently implemented in the Urban Developer Plugin) |
| Alternative supply 2 | Connect to an Alternative supply node (if available) (Not currently implemented in the Urban Developer Plugin) |
Node Outputs
| Node Output | Notes |
|---|---|
| Blackwater | Connect to a blackwater stream (if necessary) (Not currently implemented in the Urban Developer Plugin) |
| Greywater | Connect to a greywater stream (if necessary) (Not currently implemented in the Urban Developer Plugin) |
| Irrigation/Other | Connect to any other end-use stream. For example, you can track your garden irrigation through this end-use, and link it back to a pervious area node in your model to capture the effects of run-off of irrigating your pervious area. (Not currently implemented in the Urban Developer Plugin) |
Node Properties
| Node Property | Notes |
|---|---|
| Diurnal pattern | The node will use the diurnal use pattern set in the Appliances option in Urban Settings |
| Indoor average demand | The average indoor demand each month in litres/day/household. This is used to characterise the seasonal variation in water usage. Four Indoor end-uses are available: Hot Water, Laundry, Toilet and Other |
| Outdoor average demand | The average outdoor demand each month in litres/day/household. This is used to characterise the seasonal variation in water usage. Two Outdoor end-uses are available: Garden and Other |
Total Demand Proportion (for indoor & outdoor end uses) | For each end use, enter the percentage of total indoor or outdoor demand. The Total Demand Proportion can also be used to capture the proposed effects of demand management strategies. Percentages for indoor end-uses must sum to 100, and percentages for outdoor end-uses must sum to 100. |
Supply Priorities (for indoor & outdoor end uses) | For each indoor/outdoor source, enter an order of preference for supply; eg for the end use "Toilet":
The option Don't Supply specifies that mains water, rainwater, etc will not supply that particular end use. |
| Discharge breakdown (for indoor & outdoor end uses) | For each end-use, specify the percentage of water discharged as blackwater, greywater, or other wastewater. The percentages must sum to 100%. |
| Demand Management Reduction (for indoor & outdoor end uses) | For each end-use, specify the percentage reduction in demand to simulate demand management options. |
User Interface
The Average Water Use node currently does not support a graphical user interface for editing. Instead, the model parameters can be configured via Scenario Input Sets (Edit»Scenario Input Sets). The Input Set syntax and node parameters are illustrated below:
