Fire Water Tank Inspection

Short answer: A fire water tank is a separate water reserve that provides an uninterrupted water supply to sprinkler, hydrant, and cabinet systems. It is periodically inspected under the Fire Water Resources Management Regulation (BYKHY) framework in terms of volume, fill level, automatic filling, and structural integrity.

The fire tank is the source of the entire water-based fire extinguishing system. Insufficient water level, a malfunctioning filling valve, or leaks will leave the system without water in the event of a fire.

Periodic inspections ensure that the tank will have enough water to meet the designed flow rate for the necessary duration in the event of a fire.

What is checked?

  • Maintaining water level and fire reserve (required volume).
  • Automatic filling valve (float) and supply line
  • Level indicator and low level alarm.
  • Tank internal/external structural integrity and leak-proofness.
  • Suction lines, vortex arrester and filter.
  • Protection against freezing and contamination.

Methodology and Design Basis

The inspection includes verifying whether the storage volume meets the design requirements, functional testing of the level/filling systems, and structural inspection. BYKHY determines the fire reserve volume according to the building class and the systems it supplies; it is essential that this volume is not allocated for other uses.

Legal Basis and Period

Fire water tanks are evaluated within the scope of BYKHY (Fire Water Resources Management Regulation); inspections are carried out and reported by authorized personnel.

Common Nonconformities

  • The fire reserve is used up for daily purposes.
  • Non-functioning/leaky automatic filling valve
  • Absence of low-level alarm
  • Suction line blockage due to sediment, dirt, or algae.

Frequently Asked Questions

How much water should a fire tank hold?

The building class and the systems it is supplied by are determined by BYKHY (Building Quality Standards) and design calculations.

Can fire water be used for other purposes?

No; the fire reserve must always be protected and separated from other uses.

Why is automatic refueling critical?

It ensures the continuity of the reserve by replenishing the level that decreases due to use or evaporation.
