Urine diverting dry toilet in Guangxi-Province, China (supported by SIDA and Unicef)
Large ecosan project in the phase of up-scaling 1997, pilot project funded by
SIDA/Unicef, 70 ecosan (urine diverting dehydration toilets) built in pilot village, Dalu Village
1998, 10.000 urine-diverting toilets were built in 200 ecosan villages in Guangxi
2002, 100.000 ecosan toilets in Guangxi
2003, 685.000 ecosan toilets in 17 provinces (Ministry of Public Health)
Factors of success: cultural acceptance, political commitment, technical flexibility, low cost, income generation, pressure from water pollution and water scarcity, promotion and marketingso
