Changes

==Adequacy==

The Urinal can be used with or without water and the plumbing can be developed accordingly. If water is used, it is mainly used for cleaning and limiting odours (where the water acts as a water-seal). Water-based Urinals use 8 to 12 litres of flushwater, whereas low-flush models use less than 4 litres of flushwater. Because the Urinal is exclusively for urine it is important to also provide another toilet to be used for faeces. Waterless Urinals are available in a range of styles and complexities.

==Health Aspects/Acceptance==

The Urinal is a comfortable and easily accepted User Interface. In some cases, the provision of a Urinal is useful to prevent the misuse of dry systems (e.g. [[Urine Diverting Dry Toilet|UDDT]]). Urinals, although simple in construction and design, can have a large impact on the well-being of a community. When men have access to a Urinal, they may be encouraged to refrain from urinating in public, which reduces unwanted odours and allows women to feel more comfortable. Men have generally accepted waterless Urinals, as they do not call for any change of behaviour.

==Maintenance==

Maintenance is simple, but should be done frequently. Minerals and salts may build up in pipes and on surfaces where urine is constantly present. To prevent scaling, slightly acidic water and/or hot water can be used to dissolve any minerals that form. All of the surfaces should be cleaned regularly (bowl, slab and steps) to prevent odours and to minimize solids formation.
