The 11^th World Toilet Summit was hosted in Hainan Province, China during 22-24 November 2011.  The annual summit serves as a platform for discussion on the global sanitation crisis that is affecting billions of people globally.  The Toilet Design Award (TDA) was launched at the 2011 Summit to showcase the improvements in toilet design.  The competition was divided into the three categories – urban, low-cost and tourist area toilets.

Chen Xiaojing, Expert Toilet Designer commented “This competition has demonstrated the application of energy conservation and environmental protection technologies in the design of toilets.  It is of great help in increasing the quality of toilets.  Many designs actively apply solar energy and water collection technology.  In addition, given the conditions in tropical area, the designs of ventilation and lighting are also very creative and green, which can give people a favourable experience when they go to the toilet.”

Among the variety of toilets, one transparent toilet was highlighted during the event.   Although transparent is not always the best aesthetic choice for a toilet, it could save up to 40% more water when flushed.  A 16-year-old girl was awarded for designing a toilet that made sure bathroom goers would flush before leaving, as only the flush button would unlock the toilet door.  In total, over 115 toilet design entries were received by participants in over 15 countries.
