Chapter 14 Water Supply
2
Learning Objective 1

• Explain the ways water supply system components
  are used by firefighters.

3
There are two types of water supply systems
firefighters use.
4
Water supply sources are found in a variety of
locations.
5
The amount of water needed from a supply source
considers several factors.
6
Water treatment or processing facilities remove
impurities in water.
7
The means of moving water depends on the original
source for the water.
(Cont.)
8
The means of moving water depends on the original
source for the water.
(Cont.)
9
The means of moving water depends on the original
source for the water.
10
REVIEW QUESTION

• What are the three main means of moving water
  used by firefighters?

11
Piping is an important aspect of the water
distribution and storage system.
12
Storage tanks are also another component in the
system.
13
Isolation and control valves use several methods
to interrupt water flow.
14
Isolation valves are used to isolate sections of
the water supply system.
15
Control valves are located between public and
private systems.
16
Fire hydrant locations vary depending on the
water system.
17
Friction loss and locations can affect volume and
pressure.
18
REVIEW QUESTION

• How do the main components of water
  distribution and storage systems operate?

19
Learning Objective 2

• Describe types of fire hydrants and hydrant
  markings.

20
Fire hydrants, while a dependable water source,
can fail.
21
There are several commonalities in hydrants a
firefighter may encounter.
22
Dry- and wet-barrel hydrants are designed for
different climates.
23
REVIEW QUESTION

• What are the main types of fire hydrants?

24
Fire hydrant markings can be used to designate
flow capacity.
25
Learning Objective 3

• Explain fire hydrant operation and inspection
  considerations.

26
Hydrant operation and inspection requires
specific knowledge.
27
Some potential problems may be present during
hydrant inspections.
28
REVIEW QUESTION

• How does the operation of a dry- barrel hydrant
  compare to that of a wet-barrel hydrant?

29
Learning Objective 4

• Explain alternative water supply sources and
  methods of access.

30
Alternative water supply sources can be found in
a variety of places.
31
Drafting operations may be required to access
alternative water supplies.
32
REVIEW QUESTION

• When should alternative water supplies be
  identified?

33
Learning Objective 5

• Describe methods used for rural water supply
  operations.

34
Rural water supply operations require planning
and practice.
35
The water shuttle method transfers water to tanks
for use.
36
There are several key components in a water
shuttle operation.
37
Portable tank types require specific set up
guidelines.
38
Water supply volume is calculated on several
variables.
39
You must know ways to use and regulations for
water supply apparatus.
40
Use of self-filling vacuum mobile apparatus has
increased.
41
Relay pumping is used when the water source is
close enough to the fire scene.
42
REVIEW QUESTION

• What are the common operations for accessing
  rural water supplies?

43
Summary

• Because water is the primary fire extinguishing
  agent used by firefighters, and because fires
  often occur considerable distances from major
  water sources, fire departments must develop ways
  to transport the available water from its source
  to the place it is needed.

(Cont.)
44
Summary

• Firefighters must be familiar with the water
  supply systems in their response areas.
• They must know about water sources, pumping
  systems, gravity systems, and the system of
  underground water mains used to distribute the
  water.

(Cont.)
45
Summary

• They must also know how to inspect, maintain, and
  operate the fire hydrants in their jurisdictions.

  connections.
• This objective is measured in Skill Sheet
  14-I-2.

48
Learning Objective 8

• Connect and place a hard-suction hose for
  drafting from a static water source.
• This objective is measured in Skill Sheet
  14-I-3.

49
Learning Objective 9

• Deploy a portable water tank.
• This objective is measured in Skill Sheet
  14-I-4.
