Fire Hydrant Systems provides the most effective means of manual fire suppression when controlled by Fire Brigade personnel. Availability of fire hydrant is essential to fire protection. Fire hydrants may be used to control the spread of a fire, protect neighbouring properties and extinguish an outbreak of fires. Although fire hydrants are installed within properties for use by fire brigade, they may also be used by trained personnel. An adequate source of water is a fundamental consideration in the design of a fire hydrant installation and may comprise water from more than one source. A source based on 4 hour duration at the design flow rates is regarded as a minimum safe quantity to enable fire brigades to commence an initial attack to limit fire spread, protect neighbouring properties and extinguish the fire. Fire Hydrant System need to be regularly inspected, tested and maintained to ensure continued readiness for use. Where pump set is installed regular maintenance is essential.

The operation of a fire hydrant, involves the attachment of a fire hose to a landing valve, then the valve is opened to provide a powerful flow of water. This hose can be further attached to a fire engine, which can then be used as a powerful pump to boost the water pressure and possibly split into multiple streams.

The pumping facility forms the heart of the fire Hydrant System. The pumps are basically uses water as extinguisher. In certain types of fires, special branch pipes are used to deliver Foam.A raging fire without a proper extinguishing system can be devastating. Hence there is an emphasis on a fire Hydrant system.

In Fire Hydrant System the Water in large quantum is pumped continuously with tremendous force and velocity so as s to reach the seat of fire. Hydrant valves are located at strategic points by virtue of which no place in the premises go unprotected. These work as outlets of water through the Fire Hose. Generally the water is stored in underground sumps, Ground level Water Tanks or Over Head reservoirs. The capacity of theses tanks can be derived based on the nature of hazard I.e., whether it is a residential apartment or a commercial building and also depending on the exact height and floor areas, these capacity is determined

The Piping Network

usually runs underground and finally emerges out of Ground at various points of utility. The network of piping carries water from the point it is pumped into, till the Hydrant and is designed to cater to the pressure within the pipes. It also runs along the height of the building parallel to the staircase having hydrant point at each staircase.

Hydrant Points

are located at required span between each other, at strategic points so as to be able to combat the fire from all sides. Near each Hydrant point, a hose box is provided with set of fire hoses & Branch pipe with nozzle to direct the water to the base of Fire. Hydrants and its components are designed keeping in mind that no time is wasted from the time the fire is detected and the fire fighting commences
