How to build an Urine Diverting Dry Toilet, UDDT

Urine Diverting Dry Toilet, UDDTAt the beginning, the toilet bowl used by the Dry Toilet was very simple, without the water trap. The solids and liquids felt directly to the drying buckets under the surface. In 2010, a Urine Diverting Toilet Bowl was built and this new toilet bowl transformed the Dry Toilet in an UDDT: Urine Diverting Dry Toilet.
Estuardo Quispillo, technician and instructor from EcoSur Ecuador went to Haiti to train the staff in UDDTs building using a very practical fiber glass mould.


With this fiberglass mould is very easy to produce toilet bowls concrete moulds. The fiberglass mould weights only 30 kg and can be moved easily to the construction site. Once there, an UDDT concrete mould per day can be built.

EcoSur can give all the technology transfer for UDDT production (including the fiberglass mould) as well as the construction of the Dry Toilet "Otji" style. Please contact us for further information.
