Water Tanks for Bushfire Protection
What Type of Water Tank for fire fighting?
Water tanks made from metal are extremely durable because they keep their structural integrity during a bushfire. Researchers from the CSIRO and Monash University have conducted extensive testing on the performance of water tanks in bush fires. They found:
Stainless Steel Tanks did not burn or split when fully exposed to fire for over 30 minutes. They became slightly scorched but there was no structural damage and only minor water loss.
Aquaplate (Colorbond) Tanks maintained structural integrity in a fire but when the temperature reached above 65 degrees, the thin plastic lining on the inside of the tank began to delaminate, causing slight water loss.
What size water tank for fire fighting?
It’s important to remember that if you install a tank for fire-fighting purposes, a minimum capacity of 10,000 litres is required. Anything less will not provide enough water to fill a fire truck or effectively use around your house or outbuildings. Additionally, the hoses and fittings should be durable enough to withstand being dragged through an active fire.
If you plan to use the tank for both fire-fighting and general property use, it’s advisable to opt for a larger capacity. For instance, a 30,000-litre tank could be installed, allowing 20,000 litres for everyday use and reserving 10,000 litres for fire-fighting. This way, you can arrange the tank fittings to ensure that there is always enough water available for fire emergencies.

Water Tanks BAL ratings or BASIX Requirements
The tanks can be made to have the Storz fitting [NSW] or Camlock fitting [Qld] installed to meet the local council requirements for the BAL Rating, on your property.
If you have a single water tank designated for fire-fighting, it must be equipped with two separate outlets—one for domestic water use and another for fire-fighting purposes. The outlet supplying water for household needs should be positioned higher up the tank, ensuring that the water below this point is reserved specifically for fire-fighting.
