State of Georgia BASIC FIRE FIGHTER TRAINING COURSE WATER SUPPLY

WATER SOURCES FOR FIRE FIGHTING Municipal water systems Private water systems Natural supplies Manmade sources Water Supply

FIRE HYDRANTS Wet barrel Dry barrel Used in warm climates Water is always in the barrel Operating nut at each outlet and on bonnet Dry barrel Used in cold climates (Georgia) Water not in barrel Operating nut on top of bonnet Water Supply

CONNECTING TO A FIRE HYDRANT 2½” Outlet Take needed equipment Wrap hose one turn around hydrant Place foot on hose & signal driver to lay hose Place hydrant wrench on operating nut Remove caps from outlet(s) to be used Open hydrant to flush debris (10-20 sec.) Close hydrant Attach hose(s) to hydrant outlet facing fire Attach valve to not-used 2½” outlet Fully open hydrant on signal from pumper operator After use close hydrant Water Supply

HOSE LAYS Forward lay Female coupling off truck first Water Supply

HOSE LAYS Reverse lay Male coupling off truck first Water Supply

HYDRANT MAINTENANCE As required locally Obstructions to hydrant Obvious damage Rust and corrosion Caps removable Hydrant operational Lubricate Water Supply

DRAFTING The process by which water is lifted by means of a vacuum from a static water source into a pump Water Supply

EQUIPMENT NEEDED FOR DRAFTING Pumper Hard suction hose Strainer Mallet Water Supply

A portable device that serves as a temporary reservoir for water PORTABLE WATER TANK A portable device that serves as a temporary reservoir for water Folding Frame Self-supporting Water Supply

TRANSFERING WATER BETWEEN PORTABLE TANKS Simple Siphon Method Utilizing a hard suction hose or other non-collapsible tube or pipe to allow water to flow from one portable tank to another by atmospheric pressure Water Supply

MOBILE WATER SUPPLY OPERATIONS A method of transporting water from a water source to a fire attack apparatus by use of tankers, pumpers, or other apparatus Water Supply

MOBILE WATER SUPPLY OPERATIONS Procedure Supply apparatus transports water to the fire attack pumper Supply apparatus off-loads water: Supply apparatus pumps directly into tank on pumper Pumper drafts directly from the supply apparatus Water off-loaded into portable tank After unloaded, supply apparatus goes to fill point Supply apparatus is filled with water Supply apparatus returns to fire attack pumper Cycle is repeated Water Supply

RELAY PUMPING OPERATION A method of moving water a long distances by the use of two or more apparatus where as one apparatus pumps water to the next May be needed when the length of hose line from the water source to the attack apparatus is such that there is insufficient water/pressure to provide the required fire flow Water Supply

RELAY PUMPING OPERATION PROCEDURES Apparatus are spaced from the incident to the water source Hose lines are laid from apparatus to apparatus Pumping apparatus sets up at the water source First Apparatus pumps from water source to the intake of the next pumper The second apparatus pumps to the next and so on The last apparatus will be operating at the scene Operation can consist of as few as two apparatus or as many as required Water Supply
