The state government of Queensland, Australia made it compulsory for new dwellings to have a rainwater tank installed as of January 1, 2004. The vast majority of these are in the form of underground water tanks. This is actually a fantastic method to collect rainfall in order to use as water for use in the future. There are often water restrictions imposed on the state, and indeed the country as a whole, and this is a great way to have access to water as and when you need it.
It is estimated that the average Australian household will discharge anywhere up to 200,000 litres of water into the storm water drains on an annual basis. This was seen as a huge waste and by installing an underground water tank, you are typically helping the environment as well as ensuring you have an ample supply of water whenever you need it.
Concrete Water Tanks
There are many different types of water tanks available, including plastic, fibreglass and galvanised, although the most popular is proving to be concrete. Concrete water tanks hold many advantages over the other types of material and there have, in fact, been many problems caused by these alternative materials.
There have been instances of copper poisoning from the use of plastic water tanks. It is said that the acidic rainwater which forms in the plastic water tanks can actually corrode the system of copper piping used, thus causing a reaction and potentially causing copper poisoning. This in turn will mean that you are likely to find dissolved copper in your drinking water, which can cause no end of ailments and illnesses. These include, gastric-related issues, headaches and there have even been certain cases of cirrhosis of the liver which have been caused by drinking this water over a period of time.
Other Benefits of Concrete Water Tanks

- Concrete is actually made up of materials which are said to be fairly environmentally friendly.
- Concrete tanks have the ability to be buried underground – typically 90% to 100% and this will provide many other benefits including ensuring that the water you drink is much cooler than other systems used.
- You can more or less totally eliminate the growth of algae, as algae doesn’t like the cool temperatures at which a concrete underground water tank will remain.
- Simply by removing algae from a system such as this, you will experience far less problems with the valves and pumps used, therefore saving yourself money on potential repairs.
- Even if you have a huge water tank installed, you will typically see less than 10 centimetres of this above the ground and in most cases, the protruding part of the water tank is actually the lid.
- You will find that concrete water tanks have a far longer lifespan than the other materials used and they are extremely hard-wearing, which means you won’t have to worry about wear and tear of using a system such as this.
- The sweltering temperatures of the summer months will not affect the concrete in the same way as some of the others materials, mainly that it will be completely fire proof.
