Tank refurbishment is the process of restoring an existing water tank to optimal working condition, rather than replacing it entirely. This may involve repairing leaks, reinforcing structures, relining interiors, cleaning, or applying protective coatings. It’s a cost-effective, sustainable solution that extends your tank’s lifespan and improves water quality.
In Sydney, where water storage is critical for commercial, industrial, and residential properties, tank refurbishment helps property owners meet operational needs without the high expense and downtime of a full replacement.
Why Choose Refurbishment Over Replacement?
Refurbishment offers many advantages:
- Cost savings – Often 30–50% cheaper than replacing a tank.
- Faster turnaround – Many refurbishment jobs are completed in days, not weeks.
- Sustainability – Extending a tank’s life reduces waste and resource use.
- Compliance – Ensures tanks meet Australian Standards such as AS1851 for fire water storage systems.
- Custom solutions – Repairs can be tailored to your tank type, size, and condition.

How to Repair Water Tank Leakage
Water tank leakage can be caused by corrosion, cracks, poor seals, or liner damage. The repair process typically involves:
- Draining and cleaning the tank.
- Inspecting and locating leaks.
- Applying patch repairs or sealants.
- Installing a new liner if needed.

How Long Does Tank Refurbishment Take?
The timeframe depends on:
- Tank size – Small potable tanks: 1–2 days; large industrial tanks: up to 7 days.
