There are many benefits of water tanks , but there is one impactful effect that it do es not only apply to specific households, but to the totality of water consumption. As you list everything that you are doing regularly with the help of water, then check the things where you can use “used” water instead of water directly coming from your faucets at home. Some of it is watering of plants, washing our clothes, cleaning our house, washing our dishes, and other things where clean water is not really needed. Based on the report given on the water consumption of Australian residents, there are 240,000 liters of water annually which are being allotted for domestic purposes which are mentioned earlier. That is approximately 40% of the total water consumption, which is almost half of the total water usage for a year in Australia.
Those 40% can be saved in a year or the 240,000 liters of water can be used in succeeding years if everyone will use a water tank. You also have an option to buy cheaper water tanks for sale if your budget is not enough to have one at home. Focusing on the domestic usage alone will help not just the Australian government, but the totality of the Australian residents. Then you could make some adjustments on other areas where water can be conserved more other than the domestic side. You can even focus on the volume of water that you are using when you take a bath, which actually contributes to the volume of domestic usage.
