Perth Water Tanks Guarantee Adequate Water Supply during a Bushfire

Homes in the City of Swan came close to being razed to the ground by a bushfire early January, which claimed more than 5,000 hectares of forest. With the help of 50 km/h winds and the Perth heat, the fire swept across lush vegetation. Fortunately, a contingent of firefighters were able to fight off the blaze, as well as ember attacks in the suburbs.


Should another bushfire of this magnitude happen again, not even adequate defensible space will be enough to defend the home from a fire. In times when firefighters need access to water lines, there’s no guarantee that homes will have running water to fight off the blaze. In addition, power interruptions may render pumps inoperable in a bushfire.

Even if you have your own pump and draw water from underground, there’s a chance that the charred residue will contaminate the water. As a result, both underground and surface water may be deemed unfit for consumption following a fire. It’s for these situations that homes should come prepared with their own water supply.

At the very least, Perth water tanks should suffice. These corrugated steel tanks are connected to the gutter to collect rainwater and come with a spigot at the bottom for easy access. While it may seem that it rarely rains in Perth, the winter months between June and August bring heavy rains to the region. This is due to the formation of strong cold fronts and low pressure areas.

A Perth water tank will come in handy during this time. Those from Rainfill Tanks and Curved Roofing Supplies, for example, can be designed to hold up to 22,730 litres. The amount of rainwater you can collect is dependent upon the average rainfall for your location, the roof surface area supplying rainwater to your tank and the number of down pipes connected to your tank. The formula to use when calculating how much water you can collect is ‘One millimetre of rain falling on one square metre of roof (1m x 1m) will collect one litre of water’

Based on these calculations a water tank can hold many seasons’ worth of rain (excluding occasional rains in non-rainy seasons).

You can store your water for emergency use when the situation calls. Everyone, not just firefighters, must play their respective roles in protecting the things that matter.
