When modeling a water supply network,
00:05
it is necessary to understand the role water plays in support infrastructure.
00:11
While support infrastructure components are typically not included in a
00:14
model or they are only used in specific tasks.
00:18
A basic understanding is needed to provide comprehensive modeling.
00:22
One common type of support infrastructure is the hydrant
00:27
typically used by the fire service.
00:29
Hydrants are also used for pipe flushing exercises.
00:32
Hydrants reserved for fire service are typically
00:35
known as fire hydrants and hydrants intended
00:37
for general use by a water company are commonly known as washout hydrants.
00:42
Hydrant types and mechanisms vary by country
00:46
in much of the world.
00:47
Hydrants are situated above ground and
00:49
connected vertically to the distribution main.
00:52
However, in other countries,
00:54
hydrants are installed in small underground
00:56
chambers often directly above the pipeline
00:60
info works.
01:01
WS PRO allows you to model both fire and
01:03
washout hydrants through the use of hydrant objects.
01:07
Another support infrastructure component is the surge vessel
01:11
while surge vessels are only relevant to transient analysis in WS PRO,
01:16
they are used in distribution networks to
01:18
protect pipelines from surge or transient,
01:21
particularly when caused by pump failures,
01:24
most commonly found at pumping stations
01:27
surge vessels are pressurized metal tanks filled
01:29
with a mixture of air and water that releases into the pipeline.
01:33
If the pressure falls,
01:35
this prevents a scenario in which a pump instantaneously fails.
01:40
Instantaneous failure typically causes a negative wave of pressure away from
01:44
the pump which in turn causes a vacuum to form.
01:48
Search vessels are designed to act in emergency situations.
01:52
There are other search protection or balancing devices such as search towers.
01:56
Although these are less common
01:59
surge vessels are not considered a part of standard network
02:01
modeling and belong to the more specific transient analysis.
02:06
