Title: Water closet

Abstract: A water closet in which a substantial reduction in water use is accomplished by flushing liquid waste from the bowl using a high-pressure stream of water which passes through the bowl and into an S-trap. Solid material is flushed in the normal way. The high pressure stream occurs in two phases; a first phase which has high momentum and evacuates the bowl, and a second phase which has low momentum and refills and reseals the bowl.
