Understanding support infrastructure

00:03

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

However,

02:06

it is important to understand the role they play in support infrastructure.
