Lot Scale Storage

Warning

This node is currently under testing

The Lot Scale Storage node serves to implement a representation of lot-scale water capture and reuse systems. The node functions by defining the capture stream, up to three reuse streams, the volume of the storage and on which Lot template the storages are implemented. The reuse streams are priorities with reuse priority 1 having the highest priority followed by 2 and 3. Water will first be provided to the stream with the higher priority until the demand is fulfilled. The overflow of the storage will be directed to the capture stream. As a result a lot scale storage will reduce the capture stream and the demand of the reuse streams. Note that reuse priority 1 needs to be set. The other reuse streams are optional.

Storage Model

The storage behaviour is implemented as a simple bucket or conceptual model and is linked into the flow network based in the defined stream configuration. [Mitchell et al., 2001]

Storage Cascades

Lot scale storages can be arranged in a cascade. The order of the storage is defined by the order of how the lot scale storages are added to the workflow.

Capture streams and reuse streams are routed through the storage cascade. This means that for example a grey water harvesting system represented as a lot scale storage can provide water for non potable and outdoor use. A rainwater harvesting tank connected in series after the grey water harvesting system will provide additional water for outdoor use.

Parameter

Note

The Lot WB Template ID needs to be set correctly. You can find the lot template ID’s currently defined on the map under parcel (this will be assisted by a drop down in a future release)
