We recommend that you specify which junctions represent hydrants directly on EPANET or your GIS files. Otherwise, Qatium will not be able to identify them. You can do it following the instructions in the table below.
Data you add to your files
| GIS editor | |
|---|---|
| Field | Group |
| Attribute | hydrant |
| EPANET | |||
|---|---|---|---|
| Option 1 | Option 2 | ||
| Property | Description | Property | Junction ID |
| Value | hydrant | Value |
H_ E.g.: H_12344 |
How Qatium processes that data
If not specified, it’ll remain as junction.
Notes:
You can also specify hydrants directly in the .inp file using a text editor. Add ;_hydrant to the description (i.e., the extra properties column that appears in fifth position after the semi-colon).
Emitter coefficient
Data you add to your files
| GIS editor | |
|---|---|
| Field | Emitter |
| Attribute | <number> |
| EPANET | |
|---|---|
| Property | Emitter Coeff. |
| Value | <number> |
How Qatium processes that data
If not specified, Qatium will ignore it.
Water quality
Currently, Qatium only supports water age to calculate Water Quality. To have accurate water quality data shown in Qatium, you must include the water age parameter in your files.
EPANET- Set Parameter property to Age in the Quality options in EPANET
- Set the Initial Quality property for all the nodes
Include the Water Age property inside your GIS data. Then add a number (up to 2 decimal places) representing the number of hours.
| GIS editor | |
|---|---|
| Field | Water Age |
| Attribute | <number = hours> |
