As more older Perth households shift to modern heating solutions, older kerosene heating oil tanks are becoming less common. If you’ve recently upgraded or no longer use your kerosene system, it’s important to decommission your tank safely and responsibly. Here’s what’s involved and why it matters.

Why Decommissioning Is Important
Unused kerosene tanks pose several risks:
Environmental hazard: Leftover kerosene can leak and contaminate soil or groundwater.
Fire safety: Old tanks with residual fuel vapours are a potential fire risk.
Structural risk: Corroding tanks, especially underground ones, can weaken over time and collapse or leak.
Legal compliance: In some areas, leaving tanks in place without proper decommissioning may breach local council or EPA guidelines.
When Should You Decommission?
You should consider decommissioning if:
Your kerosene heating system has been removed or is no longer in use.
The tank is more than 20 years old.
You’ve switched to electric, gas, or other modern heating options.
You’re selling your property and want to ensure it’s free of legacy risks.
What’s Involved in Decommissioning?
Decommissioning doesn’t just mean “leaving it be.” It’s a process that should be done professionally and includes the following steps:
1. Tank Inspection
A qualified technician will assess the tank’s condition, type (aboveground or underground), and contents.
2. Fuel Removal
Any remaining kerosene is safely pumped out and disposed of or recycled in accordance with environmental regulations.
3. Tank Cleaning
The interior is cleaned to remove sludge, scale, and vapours, which reduces the risk of corrosion or fire.
4. Disconnection
All associated piping and lines are disconnected and sealed.
5. Removal or Inert Filling
Aboveground tanks: Typically dismantled and taken off-site for disposal or recycling.
Underground tanks: Normally excavated and removed, but in a small minority of situations where excavation is not possible, filled with an inert material like sand or foam to prevent collapse.
6. Final Site Check
The area is inspected for signs of leakage or contamination. If soil remediation is needed, this is done immediately.
