Chapter 14 Water Supply
2Learning Objective 1
- Explain the ways water supply system components
are used by firefighters.
3There are two types of water supply systems
firefighters use.
4Water supply sources are found in a variety of
locations.
5The amount of water needed from a supply source
considers several factors.
6Water treatment or processing facilities remove
impurities in water.
7The means of moving water depends on the original
source for the water.
(Cont.)
8The means of moving water depends on the original
source for the water.
(Cont.)
9The means of moving water depends on the original
source for the water.
10REVIEW QUESTION
- What are the three main means of moving water
used by firefighters?
11Piping is an important aspect of the water
distribution and storage system.
12Storage tanks are also another component in the
system.
13Isolation and control valves use several methods
to interrupt water flow.
14Isolation valves are used to isolate sections of
the water supply system.
15Control valves are located between public and
private systems.
16Fire hydrant locations vary depending on the
water system.
17Friction loss and locations can affect volume and
pressure.
18REVIEW QUESTION
- How do the main components of water
distribution and storage systems operate?
19Learning Objective 2
- Describe types of fire hydrants and hydrant
markings.
20Fire hydrants, while a dependable water source,
can fail.
21There are several commonalities in hydrants a
firefighter may encounter.
22Dry- and wet-barrel hydrants are designed for
different climates.
23REVIEW QUESTION
- What are the main types of fire hydrants?
24Fire hydrant markings can be used to designate
flow capacity.
25Learning Objective 3
- Explain fire hydrant operation and inspection
considerations.
26Hydrant operation and inspection requires
specific knowledge.
27Some potential problems may be present during
hydrant inspections.
28REVIEW QUESTION
- How does the operation of a dry- barrel hydrant
compare to that of a wet-barrel hydrant?
29Learning Objective 4
- Explain alternative water supply sources and
methods of access.
30Alternative water supply sources can be found in
a variety of places.
31Drafting operations may be required to access
alternative water supplies.
32REVIEW QUESTION
- When should alternative water supplies be
identified?
33Learning Objective 5
- Describe methods used for rural water supply
operations.
34Rural water supply operations require planning
and practice.
35The water shuttle method transfers water to tanks
for use.
36There are several key components in a water
shuttle operation.
37Portable tank types require specific set up
guidelines.
38Water supply volume is calculated on several
variables.
39You must know ways to use and regulations for
water supply apparatus.
40Use of self-filling vacuum mobile apparatus has
increased.
41Relay pumping is used when the water source is
close enough to the fire scene.
42REVIEW QUESTION
- What are the common operations for accessing
rural water supplies?
43Summary
- 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.)
44Summary
- 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.)
45Summary
- They must also know how to inspect, maintain, and
operate the fire hydrants in their jurisdictions.
