The urine diverting dehydration toilet (UDDT) is located in a public toilet blok in the Olympic Forest Park (OFP) in Beijing. The big hole is for the excreta, the small for urine. The switch at the wall is the light barrier to activate the slide to push the excreta to the chamber. The Olympic Forest Park is located north of the city center of Beijing, the capital of the Peoples Republic of China. Photo by P. Feiereisen in July 2009.
