how much water does the average toilet use per flush?
In the 1830s the average person in the UK would have got by on just 18 litres of water per day, however nowadays we are using over 135 litres a day (7.5 times the volume). Toilet flushing accounts for 1/3 of water used in the home today; one toilet flush using an older style toilet uses 14 litres of water.
