The Dual Flush Toilet
A dual-flush toilet is a variation of the flush toilet that uses two buttons or handles to flush different levels of water.
In 1980, with $130,000 government assistance, Bruce Thompson of Caroma developed a cistern with two buttons and flush volumes (11.0 litres and 5.5 litres). This wasn't easy because the toilet bowl had to be redesigned to make sure less water could still remove the waste.
Advantage:
The dual flush toilet system has the ability to save up to 67% of water usage.
Disadvantage:
More expensive than other low flow toilets
