Although this is the cheapest option, it is doubtful that EU financed toilets should
look like this. Hence, it is questionable how durable this superstructure is. But
however this option is much more affordable and therefore worth while to consider.
3.4 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.
For cleaning, a damp cloth may be used to wipe down the seat and the inner bowls.
Some toilets are easily removable and can be cleaned more thoroughly. 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.

3.5.1 Using urine as a fertilizer
Urine is rich in nitrogen and thus has similar fertilizing effect as that of a
nitrogenous fertilizer (Vinnerås et.al, 2003). If collected and stored in a correct
manner, it can be used in fertilizing crops and vegetables that have high demand
for nitrogen. The amount of urine to be applied should be based on the amount of
nitrogen demanded or required by a particular crop. This is often already documented
especially in respect to chemical fertilizers. If this is not known, then a rule of thumb
can be used.
