Working Principle
How It Works
A fire hydrant system stores large volumes of water in a dedicated overhead or underground tank. Motor-driven pump sets (electric + diesel backup) maintain constant pressure in a ring main pipework network. Firefighters or trained personnel connect a fire hose to landing valves on each floor and direct a high-volume water jet at the fire. The jockey pump runs continuously to compensate for minor pressure drops, alerting the system if flow demand increases suddenly.

Maintenance & AMC Tips
Annual flow test — measure actual flow vs design specification
Monthly check of all pump auto-start function and pressure settings
Inspect valves, couplings, and landing valve outlets quarterly
Drain and flush the system annually to prevent corrosion deposits
Verify terrace tank water level is maintained and inlet valve is open
Legal & Compliance Requirement
Fire hydrant systems are mandated by NBC 2016 for industrial buildings above 500 m², high-rise buildings above 15m, hospitals, hotels, and large storage facilities. They are the primary firefighting tool used by fire brigade personnel on arrival and are a non-negotiable requirement for NOC approval for most large commercial and industrial premises in India.
