Depends on how old it is. old toilets used about 5 gal. per flush. newer ones use about half that now.
A semi flush uses about half the water that a full flush uses. This saves using water when it is not necessary to use more than is required. It saves money plus helps the environment.
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.
If you have an older style toilet (15 years or more) then you are flushing away about 18 litres of water per flush. All new toilets flush an average of 13 litres per flush and many even give the choice of a 6 or 13 litre flush with the use of a dual flush button. Many municipalities in Canada have now banned the sale of old style full flush toilets. -In US and Canada people are incredibly wasteful of water in general. We use nearly 2-3 times per capita what most other countries use.

A dual flush cistern helps conserve water usage in a household by offering two different flush options - a full flush for solid waste and a half flush for liquid waste. This allows users to use less water when flushing liquid waste, reducing overall water consumption.
Using a dual flush valve in a toilet system can help save water and reduce water bills. It allows for a choice between a full flush for solid waste and a partial flush for liquid waste, conserving water with each use.
Double flush toilets help conserve water usage in households by providing two different flush options - a full flush for solid waste and a reduced flush for liquid waste. This allows users to use less water when flushing liquid waste, ultimately reducing overall water consumption.
If you want to use less water per flush, you put a brick in the bottom of the tank. You do not want to reduce the height of the water in the tank so much as use less water per flush.

Dual flush toilets usually use 3 and 6 liters of water depending on which way you push the flush handle - 3 liters for a little job and 6 liters for a major event. Single low-flush toilets use either 4.5 liters or 6 liters.
