WELLINGTON COUNTY FIRE TRAINING 2013 - 10 LESSON PLAN

OFM curriculum – Water Supply
Component – 1
Section - 10 / Lesson Plan – Water Supply
Prepared by – T.O karn
Preparation date - Jan 2013
Special Precautions
LEARNING OUTCOME(S): / ESTIMATED TIME:
The learner will be able to describe:
-  Sources for water supply
-  Water processing facilities
-  Distribution and Storage facilities
-  Hydrant types, colour code, locations
-  System pressures
-  Alternate water sources
-  Rural water supply
-  How to operate hydrants
-  Drafting
-  How to gauge water flow pressures
INTRODUCTION: / ESTIMATED TIME:
Being able to quickly supply water to the scene is a primary objective of all fire crews. Having an understanding of where and how to get that water makes us much more efficient at quickly establishing constant water flow. This in turn will help us reach our goal of safely saving lives and property.
APPLICABLE SECTION 21 GUIDANCE NOTES & SAFETY NOTE
Remember as the T/F you are a supervisor for this work period and will observe and enforce all appropriate health and safety measures for you lesson participants.

LESSON OUTLINE / TEACHING AIDS
Water Supply
Components
Source of Supply
-  Lakes, rivers, streams, wells
Water processing facilities
-  Filtration etc.
Means of moving water
-  Pumps
Distribution and Storage Systems
-  Underground piping
-  Water towers
Distribution System
-  Primary Feeders
·  Large pipes 400mm (16”)
·  Brings large amounts of water to different points of a water system
-  Secondary Feeders
·  Intermediate pipes 300mm (12”)
·  Pipes that form a grid between the primary pipes
-  Distributors
·  Grid of smaller mains 200mm (8”) supplying hydrants
Hydrants
Types
-  Dry barrel
-  Wet barrel
Parts
-  Stem nut
-  65mm caps (2)
-  Steamer Cap (1)
-  Operating Stem
-  Main Valve and barrel drains (below frost line)
Hydrant Colour Code
-  Class AA – Blue 5,000 LPM or greater
-  Class A - Green 3,785 – 5675 LPM
-  Class B - Orange 1,900 – 3,780 LPM
-  Class C – Red less than 1,900 LPM
-  Dead End – Black not reliable
Hydrant locations
-  90m (300’) in value areas
-  Usually located near intersections
-  Pre-plan your area
Pressures
Static
-  Water is not moving, it is the potential energy available to force water through a pipe.
-  Normal operating pressure
-  The normal pressure found in a distribution system during a period of normal consumption
Residual
-  The pressure left in a distribution system at a specific location when a quantity of water is flowing
Flow
-  The forward velocity pressure at a discharge opening
Alternate Water Sources
-  Yard hydrants
-  Hose hydrants
-  Draft sources
-  Cisterns and pools
-  Rivers, lakes, ponds
-  Ditches, creeks
Rural water supply
-  Ponds
-  Wells
-  Swimming pools
-  Cisterns
-  Ditches
-  Rivers, creeks
-  Tankers
-  Pumpers
-  Hydrants
System considerations
-  Resistance or friction loss
-  Corrosion
-  Chemicals in water
-  Sediment
-  Pipe size, length
-  Water hammer
Hydrant operation
-  Open and close slowly
-  Open and close fully
-  Drain completely before capping
-  Know open and close direction before trying
Drafting Equipment
-  Pumper or porta-pump
-  Hard suction hose and strainer
-  Fire hose & nozzle
-  Static water source
Determining Hydrant Flow
-  Open hydrant fully
-  Open pitot pet-cock or bleed valve
-  Place blade in stream
-  Hold parallel to port
-  Record velocity pressure / Slide # 1
