Why having a water tank is highly valuable

You may not be aware, but Australia is one of the driest continents on Earth. Antarctica is officially number one when it comes to the least amount of rainfall recorded each year, with Australia coming in right behind them. The expectation for our rainfall is not going to get any better according to many long-range rainfall forecasters. A more realistic forecast is that it is only going to get drier with even more droughts expected and each time the severity of these droughts will be worse. This is explained in more detail in the Annual Climate Statement 2019.

Expert research on predicted rainfall including this abovementioned report discusses that they expect when it does rain in Australia, we can anticipate receiving larger amounts of rain in a shorter period. This is when we will need to harvest as much of this rain as possible and the size of you tank will be important. According to SEQ Water an average person’s water consumption in 2017 on the Sunshine Coast in Queensland was 203 litres per person per day. Therefore, as a guide, if you have 4 adults living in a house without town water and we do not receive rain for a 3 month period your family would need approximately 97,440l of water tank storage to maintain this level of usage.

Above Ground
Concrete Water Tanks

Our standard roof load water tanks can be built above ground or placed in the ground. The roof of the tank must be a minimum 150mm out of the ground. The roof can accommodate pedestrian traffic only. A popular use for these tanks is to cast a clothsline into the roof.
Our standard tank size ranges from 16,400L up to 360,000L with 14 standard sizes available.

Concrete Water Tanks

North Coast Tanks offers several options when it comes to burying your concrete water tank. Our most popular options are a 5Kpa and 7Kpa roof load. A 5Kpa roof load can be buried with up to 300mm of fill (enough to grow a lush green lawn). A 7Kpa roof load can have either 300mm of fill or a driveway/ concrete slab and can accommodate light vehicles. ie Landcruiser Wagon etc.
