The document discusses hydrant systems, which provide water for firefighting. There are two types: internal systems within buildings, and external systems outside. Internal systems include pipes, tanks, pumps and outlets. External systems are similar but provide water outside. When a hydrant valve opens, water pressure drops and the pump engages to maintain pressure. Hydrant systems must meet standards for design, installation, inspection and maintenance to effectively fight fires.
Fire hydrant installation consists of a system of pipe work connected directly to the water supply main to provide water to each and every hydrant outlet and is intended to provide water for the firemen to fight a fire. The water is discharged into the fire engine form which it is then pumped and sprayed over fire. Where the water supply is not reliable or inadequate, hydrant pumps should be provided to pressurize the fire mains.

3. Introduction to Hydrant System
▪ One of the methods for extinguishing fire in towns, cities and industrial buildings is by providing hydrant systems.
▪ Fire hydrant systems consist of suitable capacity reservoirs, arrangements to impart pressure to the water, means to
convey the water to various locations and suitable water outlets at the required locations.
▪ A well-designed and well placed out hydrant system forms the backbone of entire fire protection system.
▪ There are two types of hydrant system,
1. Internal Hydrant System
2. External Hydrant System
4. Internal Hydrant System
▪ Internal Fire Hydrant System provides access to a water supply for the purpose of fighting fires inside the
building/structure to be protected.
▪ Internal Fire Hydrant System is installed of pipes, water tanks, pumps, hydrant outlets, hose reel, hose box containing
hose pipe & nozzle.
5. External Hydrant System
▪ External Fire Hydrant System provides access to a water supply for the purpose of fighting fires outside the
building/structure.
▪ External Fire Hydrant System is installed of pipes, water tanks, pumps, hydrant outlets & hose box containing hose
pipe & nozzle.
6. Operation of Hydrant System
▪ Under normal circumstances, a fire hydrant system is pressurized with water ready for emergency use.
▪ When a hydrant valve is opened, the system experiences a drop in water pressure.
▪ The drop in water pressure is detected by a pressure switch which in turn starts the pump, drawing water from the
water supply to increase the water pressure of the system.
▪ Water from the hydrant is then directed through the lay flat fire hose to a nozzle which is then directed to the seat of a
fire.
7. Before you use the hose reel:
✓ Alert everyone in your immediate vicinity.
✓ Activate the emergency alarm system in your building.
✓ Contact the fire brigade by calling 101.
✓ Alert the designated Fire Warden.
✓ Verify the fuel of the flame (if it is not a class A fire, do not use a hose reel).
Using the reel:
o Ensure that you are standing a safe distance away from the flame and have
a clear path to the nearest exit.
o Check that the nozzle is in the closed position.
o Turn on the valve.
o Reel the hose out until you have enough length to reach the flame.
o Move the nozzle into the open position to allow the flow of water.
o Aim the stream of water at the base of the fire, always from a safe distance.
o Exercise caution and use the nearest exit if the flame is out of control or if
you feel threatened.
Internal Hydrant System
8. External Hydrant System
Hydrant Valve Operation:
o Most hydrants open when the operating nut is turned in a counter
clockwise direction
o Always open and close hydrants slowly
- Opening a hydrant too quickly can cause a sudden decrease in
pressure that could create vacuum in the distribution system;
back-siphonage may occur
- Closing a hydrant too quickly can result in water hammer and
may damage the distribution system
o When operating a hydrant, the valve should be fully open
- 18 to 22 turns of the hydrant valve will fully open or close the
hydrant
o The hydrant valve must not be used to throttle the flow; a fire
hose nozzle or a gate valve attached to the hydrant nozzle can be
used

▪ The distribution of wet riser installation in the building should be so situated as not to be
farther than 30 m from any point in the area covered by the hydrant and at a height of
1 m to 1.2 m from the floor.
▪ Landing valve, connected to a pipe taken from the terrace pump delivery should be provided
at each floor/ landing, A hose reel and directly tapped from the down-comer pipe should also
be provided on each floor/landing.
▪ No portion of a protected building should be more than 45 m from an external hydrant, and where this
requirement cannot be met, internal hydrants are provided.
17. Testing of hydrant system
