Between 6 to 13 litres
In a modern toilet you use 13 litres per flush.
If the toilet works each time on one flush, they use roughly half the water of a standard toilet. You would then use half as much a month on the toilet. They do not always flush completely on the first flush and the toilet is only a part of the water bill.
It takes 1 bucket of water when we flush.
One gallon or 3.8 liters.
