What should not be in a sprinkler reservoir? – The importance of regular underwater inspections

 

AtNordicSub, we have conducted numerous underwater inspections of sprinkler reservoirs in Denmark and Sweden. During these inspections, we have often observed conditions that can compromise the functionality and safety of the tank. It’s crucial to understand what should not occur in a sprinkler tank and why regular inspections are essential.

 

Unwanted conditions in sprinkler system reservoirs
A sprinkler system reservoir must always be in optimal condition to ensure effective fire extinguishing. The following conditions are unacceptable:
– Corrosion: Rust on the internal surfaces of the tank can lead to leaks and structural weaknesses.
– Deposits and sediment: Dirt build-up can block outlets andreducewater quality.
– Vegetation: Roots and plants inside the tank can damage the structure and contaminate the water.
– Biological growth: Algae and bacteria can affect water quality and cause clogging.
– Foreign objects: Objects such as debris or animals can contaminate the water and hinder equipment function.

 

Why are regular inspections important?

 

Regular underwater inspections ensure that the tank is functioning properly and meets safety standards. Benefits include:
– Early detection of issues: Identifyingpotential faults before they develop into serious damage.
– Regulatory compliance: Many countries require periodic inspections to ensure fire safety.
– Safety of personnel and property: A well-functioning tank is essential in emergency situations.
– Cost savings: Prevent major repairs through early intervention.

 

Consequences of lack of maintenance

 

Failure to perform regular inspections can lead to:
– System failure during a fire: A faulty tank can prevent effective fire extinguishing.
– Legal consequences: Failure to comply with safety standards can result in fines or liability for damages.
– Increased maintenance costs: undetected issues can escalate and require expensive repairs.

 

NordicSub’sapproach to inspection

 

We useadvancedROV (Remotely OperatedVehicle) technology to perform detailed underwater inspections without emptying the tank. This ensures minimal disturbance andaccurateassessment of tank condition.

 

Our inspectionprocess includes:
– Visual assessment: Identification of corrosion, deposits and structural damage.
– Documentation: High-resolution images and videos for reporting.
– Reporting: A comprehensive report with recommendations for maintenance or repair.
