The Water, Sanitation & Hygiene program of the Bill

& Melinda Gates Foundation recently challenged 22

universities to submit proposals for how to invent a

waterless, hygienic toilet that is safe and affordable

for people in the developing world and doesn’t have

to be connected to a sewer. Eight universities were

awarded grants to “reinvent the toilet.”

The Swiss Federal Institute of Aquatic Science and Technology (EAWAG) and industrial design company EOOS propose to design and construct a functional

model of a urine-diverting toilet that recovers water

and is user-friendly, attractive, hygienic, and provides

water for cleansing.
