This paper summarizes the experiences of WECF and partners from implementingUDDTs for individual households and in schools.


This paper presents experiences with the implementation of urine diverting dry toilets (UDDTs) in the EECCA countries. In total 960 individual, 50 school and kindergarten and 7 public UDDTs have been implemented. A huge variety of different designs and materials of the sanitation facilities was applied by the WECF network partners. Experience based indications are given related to the success factors for acceptance of the individual toilets and for school sanitation projects.


Since 2003, WECF has implemented Urine Diverting Dry Toilets (UDDTs) (individual and public/schools) as sustainable sanitation solution in Central and Eastern Europe,
the Caucasus and Central Asia (EECCA), specifically in Afghanistan, Armenia, Azerbaijan, Belarus, Bulgaria, Georgia, Kyrgyzstan, Kazakhstan, Moldova, Romania, Tajikistan, Ukraine and Uzbekistan. The UDD technology is especially suitable for areas without functioning water supply and wastewater andimproves the hygienic and environmental conditions at once.
