<br>The UDDT toilet is built such that urine is collected and drained from the front area of the toilet, while faeces fall through a large chute (hole) in the back. Depending on the Collection and Storage/Treatment technology that follows, drying material such as lime, ash or earth should be added into the same hole after defecating. Men, as well as women, need to sit while urinating to ensure that the urine is diverted into the correct channel.

===Design Considerations=== '''It is important that the two sections of the toilet are well separated to ensure that a) faeces do not fall into, and clog the urine collection area in the front, and that b) urine does not splash down into the dry area of the toilet. :

Water used for anal cleaning must be kept separate in order a) faeces do not to dilute faeces or pollute fall into and clog the urine with pathogens. This requires a separate facility for anal cleaning. Small amounts of anal cleaning water can be infiltrated. Larger volumes need to be treated (together with grey water) to prevent ground water pollution.collection area in the front, and that

There are also 3-hole separating toilets that allow anal cleansing water to be separated from the b) urine and the faeces does not splash down into a third, dedicated hole. It is important that the faeces remain separate and dry. When area of the toilet is cleaned with water, care should be taken to ensure that the faeces are not mixed with water. '''

There are also 3-hole separating toilets that allow anal cleansing water to go into a third, dedicated basin separate from the urine drain and faeces collection. Both a pedestal and a squat slab can be used to separate urine from faeces depending on user preference. Urine diverting dry toilets can tends to rust most metals; therefore, metals should be made out avoided in the construction and piping of ceramicthe UDDT. To limit scaling, ferro-cementall connections (pipes) to storage tanks should be kept as short as possible; whenever they exist, fibre-enforced materialspipes should be installed with at least a 1% slope, or strongand sharp angles (90°) should be avoided. A pipe diameter of 50 mm is sufficient for steep slopes and where maintenance is easy. Larger diameter pipes (> 75mm) should be used elsewhere, durableespecially for minimum slopes, plastic and painted woodwhere access is difficult. It is important that To prevent odours from coming back up the pipe, an odour seal should be installed at the surface is smooth and hardenedurine drain.

==Health Aspects / Acceptance=Appropriateness===The UDDT is not intuitive or immediately obvious simple to some users. At firstdesign and build, users may be hesitant about using it such materials as concrete and mistakes wire mesh or plastic. The UDDT design can be altered to suit the needs of specific populations (i.e.g, smaller for children, people who prefer to squat, etc. faeces in the urine bowl) may deter others from accepting this type of toilet as well. Education and demonstration projects are essential in achieving good acceptance with users.

==Maintenance=Health Aspects/Acceptance===A The UDDT is slightly more difficult not intuitive or immediately obvious to keep clean compared some users. At first, users may be hesitant about using it, and mistakes made (e.g., faeces in the urine bowl) may deter others from accepting this type of toilet as well. Demonstration projects and training are essential to other toilets because achieve good acceptance with users. For better acceptance of both the lack of water system and the need to separate avoid urine in the solid faeces and liquid urine. For cleaningcollection bowl, a damp cloth may be used to wipe down the seat and the inner bowls. Some toilets are easily removable and toilet can be cleaned more thoroughlycombined with a Urinal (U. No design will work for everyone and therefore3), some users may have difficulty separating both streams perfectly which may result in extra cleaning allowing men to stand and maintenanceurinate.

===Operation & Maintenance=== A UDDT is slightly more difficult to keep clean compared to other toilets because of both the lack of water and the need to separate the solid faeces and liquid urine. No design will work for everyone and, therefore, some users may have difficulty separating both streams perfectly, which may result in extra cleaning and maintenance. Faeces can be accidentally deposited in the urine section, causing blockages and cleaning problems. As well, urine pipes/fittings can become blocked over time and may require occasional maintenance.

This is a waterless technology All of the surfaces should be cleaned regularly to prevent odours and water to minimize the formation of stains. Water should not be poured down in the toiletfor cleaning. As wellInstead, urine tends a damp cloth may be used to rust most metals; thereforewipe down the seat and the inner bowls. Some toilets are easily removable and can be cleaned more thoroughly. It is important that the faeces remain separate and dry. When the toilet is cleaned with water, metals care should be avoided for taken to ensure that the construction and piping of the UDDTfaeces are not mixed with water.

Because urine is collected separately, calcium- and magnesium-based minerals and salts can precipitate and build up in pipes and on surfaces where urine is constantly present. Washing the bowl with a mild acid (e.g., vinegar) and/or 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 removing blockages. However, in some cases manual removal may be required. An odour seal also requires occasional maintenance. It is critical to regularly check its functioning. == Movie = Manuals, videos, and links ===
