Abstract

A toilet to reduce water consumption for waste disposal. One embodiment uses a toilet which has a frustum-shaped bowl, whose outlet can be hermetically sealed by a saucer-shaped valve, wherein the bowl contains no water. In one embodiment, a user who deposits only urine can depress one button to automatically open the saucer vertically down and rinse and flush the urine into an adjoining drain line with about 250 ml (0.25 gallon) of water. If the user deposits solid waste, another button is depressed to release a staggered flush (first and second quantities of water) capable of causing solid human waste, test plastic balls, or equivalents to carry further in an adjoining drain line.
