Technology Review of Urine-Diverting Dry Toilets (UDDTs) Overview of Design, Operation, Management and Costs

This technology review deals with a type of toilet designed specifically for dry excreta management called the urine-diverting dry toilet (UDDT). It is a sanitation system for households and public facilities as well. The functional design elements of the UDDT are: source separation of urine and faeces; waterless operation; and ventilated vaults or containers for faeces storage and treatment. UDDTs may be constructed with two adjacent dehydration vaults or one single vault with interchangeable containers.
