In Australia, maintaining the performance and safety of water tanks—especially those used for firefighting or essential services—is more than a good idea. It’s a legal obligation. The AS 1851-2012 standard outlines the inspection, testing, and maintenance requirements for fire protection systems, including water storage tanks.
If your tank is part of a building’s fire system, failing to meet this standard can lead to safety risks, insurance problems, and even fines.
What Is AS 1851-2012?
AS 1851-2012 is the Australian Standard for the routine service of fire protection systems and equipment. It includes specific guidelines for the inspection and maintenance of water storage tanks used for fire suppression.
The standard applies to:
- Fixed fire sprinkler systems.
- Fire hydrant systems.
- Water tanks connected to fire systems (steel, concrete, or other types).
Why It Matters for Water Tanks
If a water tank supports fire protection, it must:
- Be inspected and maintained at regular intervals.
- Remain structurally sound and free from leaks.
- Provide clean water with no biological growth or debris.
- Include appropriate signage, access, and overflow systems.
Non-compliance can:
- Compromise safety during emergencies.
- Invalidate insurance coverage.
- Breach regulatory requirements under building or fire codes.
Key Inspection Requirements from AS 1851-2012
| Inspection Frequency | Action Required |
|---|---|
| Monthly | Visual inspection for leaks or obstructions |
| 6-Monthly | Internal/external tank condition check |
| Annually | Full functional inspection and testing |
| Every 5 Years | Full internal clean, inspection, and repair |
These inspections must be recorded and carried out by a competent person or licensed provider.
Role of Tank Liners in Meeting the Standard
Old or unlined tanks may fail inspection due to:
- Corrosion or flaking interior walls.
- Contaminated or stagnant water.
- Cracks, leaks, or liner delamination.
Installing a certified tank liner (e.g. PVC or HDPE, food-grade) helps meet AS 1851-2012 by:
- Creating a watertight, corrosion-resistant barrier.
- Preventing microbial growth.
- Making inspections and cleaning easier and safer.
Tank Types Covered by AS 1851-2012
- Concrete tanks.
- Steel panel tanks.
- Galvanised or epoxy-coated tanks.
- Modular and bolted tanks with liners.
All these must be inspected and, if necessary, repaired or relined to maintain compliance.
Tips to Ensure Your Tank Meets the Standard
- Schedule regular inspections (monthly, annually, 5-year).
- Keep documentation of maintenance and repairs.
- Line older tanks to extend life and improve hygiene.
- Work with certified professionals for inspection and lining.
