==Adequacy=Appropriateness= == A UDFT is adequate when there is enough water for flushing, a treatment technology for the brownwater and a use for the collected urine. To improve diversion efficiency, Urinals (U.3) for men are recommended. UDFTs are suitable for public and private applications, although significant training and awareness is required in public settings to ensure proper use and minimize clogging.
The toilet should be installed carefully with an understanding of how and where clogs may occur so that they can be easily removed. A UDFT is adequate when there is a limited supply of water for flushing, a treatment technology for the brownwater (i.e. faeces, dry cleansing material and flushing water) and a use for the collected urine. To improve diversion efficiency, Urinals for men are recommended. UDFTs are suitable for public and private applications although significant education and awareness is required in public settings to ensure proper use and to minimize clogging. This Since this technology requires dual plumbing (separate pipes for urine and brownwater)collection, which the plumbing is more complicated than plumbing for Cistern Flush Toilets. Particularly, the proper design and installation of the urine pipes is crucial, and requires expertise.
===Health Aspects/Acceptance== = Information cards and/or diagrams are essential for ensuring proper use and for promoting acceptance; if users understand why the urine is being separated, they will be more willing to use the UDFT properly. Correct plumbing will ensure that there are no odours.
Information cards ===Operation & Maintenance=== As with any toilet, proper cleaning is important to keep the bowl(s) clean and prevent stains from forming. Because urine is collected separately, calcium- and magnesium-based minerals and salts can precipitate and build up in the fittings and pipes. Washing the bowl with a mild acid (e.g., vinegar) and/or diagrams are essential for ensuring proper use hot water can prevent the build-up of mineral deposits and scaling. Stronger (> 24% acetic) acid or a caustic soda solution (2 parts water to 1 part soda) can be used for promoting acceptance; if users understand wh Ythe urine is being separated they will removing blockages. However, in some cases manual removal may be more willing to use the UDFT properly. Proper plumbing will ensure that there are no odoursrequired.
