The Blue Diversion Toilet has been selected for exhibit in the main “Fundamentals” exhibition, curated by the renowned Dutch architect Rem Koolhaas. It stands prominently next to a Japanese high-tech toilet and one of the first commercialized flush toilets - the Optimus Valve Closet developed in 1870 by Stevens Hellyer. Eawag’s Blue Diversion was selected as an example of a “21st century outhouse” that seeks to push the frontiers of technological innovation beyond the flush-and-forget solution invented 240 years ago (by A. Cummings in 1775 – it took almost 100 years to reach commercialization!).
