So, keep the body healthy, the water should fill in the amount left by food. This means the 8-ounce glasses might not be enough to keep you healthy if you eat a lot of dry food.

Now if you are wondering on the average household water usage per day Australia, here are some of the factors that could determine how much water to drink per day: 


Age is one of the factors that determines the amount of water that one drink per day. You don’t expect a kid of 12 years to drink the same amount of water as a 30 years old man. Medical experts recommend that kids between 1-4 years should drink at least 1 litre of fluid per day. Kids between 6-13 years should drink about 1.5 litres of fluid.  

For adults, men should take around 3.7 litres, while women should take 2.7 litres of fluid daily. So, if you have got a family with kids, everyone will need a different amount of water per day to remain healthy.
