Fire Hydrant System, the oldest and still one of the most effective ones, consists of the following components: Sufficiently large water reservoir Fire pump sets (Main and Standby) Jockey pump set Hydrant valves Fire fighting hoses Branch pipe with nozzles.

This is a semi-automatic system. A network of pipes is laid out depending upon the risk with hydrant valves placed at strategic places. The spacing/distance between yard hydrants is guided by norms viz.

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.
