TAF assessment undertaken by WaterAid with Netwas Uganda

The design of the Urine Diverting Dry Toilet facilitates the separation of urine and faeces into different compartments. The toilet pan or bowl is segmented to capture and drain urine at the front. Faeces are deposited at the back of the pan or bowl and fall into a separate compartment.


The following recommendations were noted to ensure sustainability and scalability of the UDDT:

  • There is a very strong need for permanent, ongoing sensitisation on how to use UDDTs and how to gain benefit from compost bi-products. Without this, misuse develops and compost potential remains un-utilised.
  • There is need to design a UDDT management model at institutional and community levels to ensure misuse is minimised.
  • Private sector involvement in purchase, trade and use of compost must be encouraged and stimulated as there is currently very weak demand.
  • Further studies on cultural barriers to use of the UDDT and compost should be carried out in different parts of the country.

Lastly, there is a need to modify design of the UDDT to respond to the desires of the different groups within communities, yet still preserve the principles and meet the same purpose. For example, adding the facility for provision and disposal of water for anal cleansing.
