Fire Hydrant System

• Fire Fighting Hydrant Systems are the most
  commonly used systems, in many residential and
  industrial projects. If you have ever seen a
  Red colour pipe, circulating around a building
  or factory, you have seen a Fire Hydrant Pipe.

Introduction

• A fire hydrant is a visible connection point
  placed in defined locations for firefighters to
  tap into a water supply. All buildings, parking
  areas, roadsides, mines, industrial areas, etc.
  must have fire hydrants.
• They are designed to provide the water required
  by firefighters instantly to fight and extinguish
  a fire.

Basics

• This is very effective extinguishing system
  suitable for various plants and high-rise
  buildings as well as commercial complexes.
• The system mainly consists of water storage
  reservoir (underground or aboveground), pump set,
  hydrant valves, hoses, branch pipes with nozzles
  and hose boxes.
• In case of fire, the hose can be connected to the
  hydrant valve with the nozzles at the outlet end
  and the pump can be started. For automatic
  operation of the pump the jockey pump is provided
  which normally pressurize the pipes and as soon
  as the valve is open and pressure reduces the
  main pump starts automatically.

How do Fire Hydrant Systems Function?

• A special well is dug, called Fire Well, where
  water is stored throughout the year for 365days.
• This water well is connected to the pump room.
  From the pump room, there are two to three main
  pipes. These pipes form a network of pipe that
  cover the factory compound and the factory.
• The pump has the work, to continuously filling
  all the pipes connected with water under
  pressure. The pressure is nearly 7bar to 10bar.
• When a fire is seen by a person, he activates the
  hydrant system and points it in the direction of
  the fire. A very strong flow of water now,
  attacks the fire and the fire is eventually
  extinguished. The pump continuously pumps the
  water to maintain the system pressure.

Advantages

• Fire Hydrant Systems are very strong and can be
  used from medium to large sized fires. Fire
  Hydrant Systems, have a long range. Since the
  Fire Hydrant System is spread out, the fire
  hydrant can attack fire from different angles.
  This entire systems requires low maintenance and
  virtually, does not leak water. Besides this,
  Fire Hydrant Systems have a long life.
• Being fixed installation it is very easy for
  operation and maintenance.
• For major fire this is most useful system to
  control and extinguish since the availability of
  water and pressure at the base of fire.
• As the hydrant ring outside building is
  underground there is no hindrance for vehicles
  and do not affect due to fire.

Disadvantages of Hydrant system

• There are few disadvantages. The first is that it
  has to be manually activated. The flow of Fire
  Hydrant System is so strong that, there are two
  men required to hold the water hose.
