Sprinkler Tank Relining Systems

Sprinkler tank relining is a critical maintenance process designed to extend the life of existing fire protection water storage tanks, ensuring they remain functional, safe, and compliant with regulatory standards. This process is essential for tanks that have developed leaks, corrosion, or other signs of wear that could effectively compromise their ability to supply water in the event of a fire.

Why Sprinkler Tank Relining is Necessary

Water tanks can deteriorate over time due to various factors, including corrosion, sediment build-up, and exposure to harsh environmental conditions. Such degradation risks the tank’s structural integrity and poses a significant safety hazard. Relining is often a more cost-effective and less disruptive alternative to completely replacing the tank.

The Relining Process

The relining process typically involves a thorough inspection and cleaning of the tank to remove any debris and identify areas of damage. Specialised coatings or liners are then applied to the tank’s interior surfaces. These materials are designed to be durable, water-resistant, and safe for potable water in cases where drinking water storage is combined with fire protection.

Types of Linings

Various lining materials are available, each suited to different types of tanks and specific water storage needs. Common materials include butyl, EPDM, epoxy resins, polyurea coatings, and fibreglass linings. The choice of material depends on factors such as the tank’s construction, the quality of the stored water, and environmental considerations.

Benefits of Tank Relining

  • Extended Tank Life: Relining can significantly extend the service life of a tank, delaying the need for costly replacements.
  • Leak Prevention: By sealing cracks and holes, relining helps prevent leaks, preserving the tank’s water supply.
  • Improved Water Quality: New linings can prevent contamination, ensuring the water remains clean and safe.
  • Cost Efficiency: Relining is generally less expensive than installing a new tank, offering savings on materials and labour.
  • Environmental Responsibility: Extending the life of existing tanks reduces waste and the environmental impact associated with manufacturing and transporting new tanks.


When planning sprinkler tank relining, it’s important to work with experienced professionals who can recommend the best lining material for your specific needs and ensure the process meets all safety and quality standards. Regular inspections and maintenance are also crucial to identify potential issues early and decide whether relining is appropriate.

In summary, sprinkler tank relining is vital to maintaining a building’s fire suppression system, ensuring that it remains reliable, effective, and compliant with safety standards. Through this process, facility managers can safeguard their properties against fire risks while optimising their investment in fire protection infrastructure.
