In InfoWater Pro UDF, a flush sequence is a series of operations that defines how a flush zone will be flushed.
00:11
The goal is to start from a clean water source, such as a pump station or a previously flushed sequence,
00:17
and then select a hydrant to be flushed.
00:21
Then, you determine which valves need closing to increase the water velocity,
00:25
so that it exceeds the minimum flushing (or scouring) velocity in the pipes leading to the hydrant.
00:31
The hydrant must remain open for at least the time needed to turn over the water in the pipes being flushed.
00:38
This is referred to as minimum flushing time.
00:42
To begin, open a UDF model with UDF hydrant and valve layers and symbols already set, and flush zones created.
00:51
From the Model Explorer toolbar, click Run to open the Run Manager.
00:56
Click Run to run a simulation and create outputs for a base scenario.
01:02
Click OK to close the dialog.
01:05
From the UDF tab, use the drop-down next to Flush Zone Manager to pick a zone in which you want to set one or more flush sequences.
01:14
For this example, ZONE_01 is chosen.
01:18
In the map, zoom to a point in the network representing a clean water source.
01:23
In this case, a fixed head reservoir is selected as the flush sequence starting point.
01:28
In the Contents panel, right-click the Pipe layer and pick Label.
01:33
The map updates with pipe IDs.
01:36
Then, from the UDF tab, click Sequence Manager to open the Flush Sequence Manager dialog.
01:42
To create a new sequence, click New.
01:45
This adds Sequence 1 to the list of sequences.
01:49
In the General tab, set a date and start flush time for the new sequence.
01:54
Also, set the number of turnovers, which refers to the number of times the pipe volume will be flushed from the main.
01:60
In this example, 3 turnovers are set.
02:03
From the Target Pipe(s) group box, click Select > to pick the pipes you want to include in the sequence.
02:09
If necessary, drag the dialog out of the way for a better view of the map.
02:14
Click and drag to select each pipe and highlight it in blue.
02:18
Here, pipes 176, 194, 196, 198, and 314 are chosen.
02:29
When you are finished making your selection, right-click the map and select Enter.
02:34
The Target Pipe(s) group box updates to show the IDs of the selected pipes.
02:39
To remove a pipe, click Remove >, and then select it on the map.
02:44
Or, you can click Delete to delete the currently-selected pipe.
02:48
To restart the pipe selection process, click Clear.
02:52
To add a specific pipe, enter the ID in the Pipe field, and then click Add.
02:58
Click Highlight Target Pipes to highlight all pipes that are currently part of the sequence.
03:03
Next, to select a hydrant as the flushing point in the sequence, open the Operations tab.
03:09
In the Hydrant to Operate group box, click the button next to the Primary Hydrant ID field.
03:14
Then, in the map, click and drag to select the hydrant you want to use.
03:19
In this example, hydrant FH31 is chosen, because it is located at the end of the sequence of pipes to be flushed.
03:27
Finally, click Isolate Target Pipes to automatically populate the Valves to Operate table.
03:33
This defines which valves are set as open and closed during each sequence, in order to isolate the pipes being flushed.
03:41
Keep in mind that there are three constraints that must be obeyed to use this tool:
03:46
There is only one flow path among the pipes defined for flushing.
03:49
In other words, the pipes must be in series without any branches.
03:54
The sequence is continuous, meaning all pipes in the current sequence are connected.
03:58
The sequence starts from a clean water source.
04:02
If any of those constraints are violated, a warning appears.
04:06
Note that warnings do not affect flush sequence results,
04:10
but simply inform you that the simulation results do not meet the specified characteristics.
04:15
When you are finished setting flush sequence parameters, click Run Sequence, noting any warnings you may receive.
04:23
Repeat the process, creating and running new sequences as needed.
04:27
To save your created sequences, from the Project ribbon, pick Save Project As, enter a name and location, and then click Save.
