Lot WB Template

Warning

This node is currently under testing

The Lot Water Balance Template node defines the “plumbing” on a lot and it connects to the sub catchment network (see Table 2 for the list of connections). For example, a typical configuration combines grey and black water to sewerage, and potable, non potable and outdoor demand to potable demand ( see Table 3 for the default configuration). With the exception of green roofs, lot scale storage and treatment systems are assigned on the basis lot templates (see nodes/lot_catchment_scale_storage). To test scenarios with a limited uptake of storage solution the Fraction of lots to assign template ID can be used. If set to < 1 it will only assign a faction of randomly selected nodes to the new template.

Note

To be able to connect flows at sub catchment level ensure that the lot scale flow is routed correctly. Otherwise the flow will be 0 Eg. for a purple pipe, non-potable and outdoor demand should be combined to non potable demand.
