Dual flush toilet. 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. It was proposed by American industrial designer Victor Papanek in his 1976 book Design for the real world, but the first practical implementation was designed in 1980, by staff at Caroma.
This led to international interest in the design. Most modern dual flush toilets use less than a gallon of water (3 liters, approximately) to flush liquid waste and around 1.6 gallons (6 liters) to flush solid waste [source: Nash ]. This is a big savings over old toilet styles that used five gallons (19 liters) or more for each and every flush. Today, dual flush toilets are used widely in Australia, Europe and Asia, and they're catching on in other areas as well.
