Fire Fighting System for High-Rise Buildings in Pakistan: A Simple Guide

Why tall buildings need their own fire fighting system

When a fire starts on the 9th floor, fire brigade ladders may not reach and street water pressure is not strong enough to push water that high. A high-rise building must be able to fight fire from inside, using its own water, pumps and pipes.

The main parts, in plain words

1. Fire water tank

A dedicated tank (underground, on the roof, or both) that stores water only for fire fighting. It must never be emptied for daily use.

2. Fire pump set

Pumps push water up the building at high pressure. A typical set built to the NFPA 20 standard has:

• An electric main pump that does the heavy work.
• A diesel standby pump that starts if the electricity fails, which matters during load-shedding.
• A small jockey pump that keeps the pipes full and under pressure, so water is ready instantly.

3. Risers (standpipes)

Strong vertical pipes that carry water to every floor, covered by the NFPA 14 standard. We use MS Schedule 40 pipe, a thick-walled steel pipe that handles high pressure.

4. Hose reels and landing valves

On each floor, a red hose reel box lets trained staff fight a small fire early. Landing valves let firefighters connect their own hoses.

5. Sprinklers

Sprinkler heads on the ceiling open automatically when they get hot and spray water right on the fire. Sprinkler systems are designed to NFPA 13.

6. Fire brigade inlet

A connection outside the building where the fire brigade can pump extra water into the system.

7. Fire alarm

The alarm warns everyone to leave while the water system fights the fire. See which fire alarm to choose.

How it all works together

1. A fire starts and the sprinkler above it opens, or someone opens a hose reel.
2. Pressure in the pipes drops.
3. The fire pump starts automatically and pushes water from the tank up the risers.
4. Water reaches the fire while the alarm tells everyone to get out.

Common mistakes we see

• Fire tank used for daily water, so it is empty when needed.
• Diesel pump never tested, or no fuel in the tank.
• Valves left closed after repair work.
• Hose reel boxes blocked by shop goods or locked.
• Cheap thin pipes that leak or burst under pressure.

Real example

At Essa Heights in Rawalpindi, a basement + ground + 10 floor tower with a roof plaza, we installed the fire fighting system together with the fire alarm, plumbing and HVAC. See more on our projects page.
