Fire Hydrant System – Details

A Fire Hydrant System is one of the most important and effective fire-fighting solutions, designed to provide instant water supply at high pressure during fire emergencies. It is mandatory in most commercial and industrial buildings as per fire safety norms.

What is a Fire Hydrant System?

A Fire Hydrant System is a network of pipes, pumps, hydrant valves, and hoses that deliver water from a storage tank to hydrant points located across the building/premises. In case of fire, firefighters or trained staff connect hoses to these hydrants to quickly extinguish the fire.

Components of a Fire Hydrant System

1. Fire Water Tank – Stores water exclusively for firefighting.

2. Fire Pump & Jockey Pump – Ensures continuous water pressure.

3. Riser Mains & Piping – Carries water across all building levels.

4. Hydrant Valves (Landing Valves) – Points where hoses can be connected.

5. Hoses & Nozzles – Used to spray water on fire.

6. Fire Brigade Inlet – Connection point for external fire tenders to pump water into the system.

7. Control Panel – For automatic and manual operation of pumps.

⚙️ Types of Fire Hydrant Systems

• Wet Riser System – Pipes are always filled with pressurized water.

• Dry Riser System – Pipes are empty and filled with water only during fire (used in high-rise buildings).

• External Hydrant System – Hydrants installed outside buildings for quick fire brigade access.

✅ Advantages

• Provides uninterrupted, high-pressure water supply

• Covers large areas and multiple floors

• Works effectively for big industrial & commercial fires

• Complies with National Building Code (NBC) and fire safety laws

• Can be integrated with sprinkler systems for added safety

Applications / Where Used

• High-rise residential and commercial buildings

• Shopping malls, hospitals, hotels, offices

• Schools, colleges, and auditoriums

• Factories, warehouses, and industrial plants

• Petrol pumps, fuel depots, and airports

Maintenance Requirements

• Weekly pump testing for pressure

• Monthly inspection of valves and hoses

• Annual full system test with water discharge

• Ensure fire water tank is always filled
