Tank Table

The Tank table is accessed via Model Data > Model Tables > Tank. Alternatively, the TableTank Tank Table toolbar button can be clicked.

 

For each tank defined in the model, a line of system data (or tank properties) is required in the Tank table.

 

The most significant fields in the Tank table are described below. Note, the same field grouping is used as for the Node table, except the Demand Allocation field group (for the Swift program) is not applicable for tanks, and the fact that the Planning field group is indeed applicable for tanks:

 

The same Network Topology data can be entered as described for the Node table, but take note of the following:

oThe Node_Type in this case is TANK. This is a node representing a reservoir, storage tank, or elevated tank. It has a fixed water level and, therefore, also a fixed pressure. To be able to better display the various different tank types in the Albion environment, Wadiso offers the following sub-types for tanks, viz.: GL_TANK (i.e. a ground level tank, also known as a reservoir), TANK, TOWER, BULK, WELL, BOREHOLE, DAM, RIVER, WTP (i.e. water treatment plant), BPT (i.e. break pressure tank) and SUMP.

oThe same Node_Code data can be entered as described for the Node table.

oThe same Exists data can be entered as described for the Node table.

 

The required Hydraulic fields are:

oWater_Level: This is the water level above the specified ground elevation for the tank.

 

When a new tank is defined in the topology, it is automatically assigned a water level of 0.0. The actual water level can be entered/edited in the Tank table.

 

The Demand field group consists of the following fields:

oDemand_Zone_AADD: This field holds the AADD (kL/d) of the zone in which the tank is located (i.e the tank must deliver this AADD to the zone).

oFuture_Demand_Zone_AADD: This field holds the future AADD (kL/d) of the zone in which the tank is located (i.e the tank must deliver this future AADD to the zone).

 

The other field groups (viz. Physical; Descriptive; Location; Results; Planning; Assets; Time Simulation Data; Optimization Data; Integrity; GUID and Geometry; and Model Functions) are the same as discussed for the Node table, except the Demand Allocation field group (for the Swift program) is not applicable for tanks, and the fact that the Planning field group is indeed applicable for tanks.
