A sprinkler tank is a key part of a building's fire protection. To ensure that it works properly when it is really needed, regular inspection of the tank's condition and function is required.
Using Cistern Solutions' modern underwater drones, the inspection can be carried out quickly, safely and efficiently - without the need to empty the tank and without disabling fire protection. Business can therefore continue as usual throughout the inspection.

How to inspect a sprinkler tank
Our underwater drone is equipped with a high-resolution 4K camera, powerful lighting and, if needed, sonar sonar that allows you to see and measure even in murky water.
The drone is controlled by an inspector who follows the process in real time and documents the entire inspection. At the end of the inspection, all material is compiled into a detailed inspection report with written notes, images and video footage.
After the inspection
After completion of the inspection, we deliver a complete report with pictures, video and clear recommendations. If necessary, we can immediately prepare a quote for the measures required to ensure optimal function and service life.
The inspection report contains
- General condition of the tank - walls, floor, partitions and structure
- Presence of corrosion on sheet metal, pipes, flanges and fittings
- Status of seals and joints - any damage or leaks
- Need for cleaning - sediment, deposits or pollution in the water
- Recommendations for action and preventive maintenance
Important when renovating a sprinkler tank
If the inspection shows that refurbishment is needed, it is important not to settle for anti-corrosion painting or a new liner. Such measures may hide damage temporarily, but will not restore the tank's bearing capacity or structural strength.
A proper refurbishment should always include rebuilding the structural steel to the same strength as when the tank was new. Weakened sections should be repaired or replaced before the shell is restored.
Simply painting over rust gives a false sense of security - and in the worst case can put both the facility and people's safety at risk.
If you receive a proposal that only includes painting or liner, always get a second expert opinion. It could be the difference between a safe tank and a future risk.
