A pipe's hydraulic carrying capacity will deteriorate with
00:28
age due to deposits on pipe walls.
00:31
Flushing restores hydraulic capacity and improves water quality.
00:35
In turn,
00:36
this prolongs the life expectancy of the distribution system
00:39
and reduces the potential for waterborne health risks.
00:42
Flushing can improve water quality by
00:45
restoring the disinfectant residual, reducing bacterial regrowth,
00:50
dislodging biofilms,
00:52
removing sediments and deposits,
00:55
controlling corrosion,
00:57
eliminating taste and odor problems
01:00
and reducing disinfectant demand throughout the system.
01:04
Flushing is also performed to restore the flow
01:07
of water and pressures for firefighting capability.
01:11
The flushing process requires a great deal of water pressure and velocity.
01:15
Therefore, for it to be most effective,
01:17
the pipe network is divided into smaller sections that are flushed individually
01:23
to keep track.
01:24
The flushing schedule object is used for development of
01:27
flushing schedules and for carrying out a flushing simulation.
01:31
The flushing schedule contains a sequence of actions to be used for
01:34
cleaning a water distribution network by flushing the pipes with water.
01:39
This object does not invent a flushing schedule but
01:42
provides you with support to design a flushing scheme.
01:46
The flushing schedule actions are viewed and
01:48
adjusted in the flushing schedule editor.
01:51
This provides an interactive design view to support
01:54
the design and evaluation of the schedule.
01:57
Finally, a few brief notes on flushing actions,
02:01
the basic assumptions about flushing actions are as follows.
02:05
Actions do not overlap in time.
02:08
Normal procedure is to isolate a line of pipes to be
02:11
flushed with water from an already flushed part of the system.
02:15
This maximizes the flushing velocities.
02:19
Branches off this single line of pipes should be closed
02:22
to avoid spreading the disturbed sediment to other pipes.
02:25
More than one flushing point is allowed for an action.

In InfoWorks WS Pro, Flushing Simulations model the effects of a flush or sequence of flushes to clean a network. Certain criteria are used to evaluate the effectiveness of flushing actions.
The hydraulic carrying capacity of a pipe deteriorates with age, due to deposits on pipe walls. Flushing restores hydraulic capacity and improves water quality by:
Flushing is also performed to restore the flow of water and pressures for firefighting capability.
The flushing process requires a great deal of water pressure and velocity. Therefore, it is most effective to divide the pipe network into smaller sections that are flushed individually.
The Flushing Schedule object is used to develop flushing schedules and to carry out a flushing simulation. The flushing schedule actions are viewed and adjusted in the Flushing Scheduler.
