'''A Dry Toilet is a toilet that operates without water. The Dry Toilet may be a raised pedestal that the user can sit on, or a squat pan that the user squats over. In both cases, excreta (both urine and faeces) fall through a drop hole.'''
HereIn this compendium, a Dry Toilet dry toilet refers specifically to the device that over which the user sits or squats over. In other literature, a Dry Toilet dry toilet may refer to a variety of technologies, or combinations of technologies (especially pits). [[Image:dry_toilet.png|thumb|right|150px|[[Dry toilet |Dry toilet]], in Mexico (for credits, click the picture)]] [[Image:slatsanc.jpg|thumb|right|150px|[[Dry toilet |SanPlat]]-type dry toilet. (for credits, click the picture)]] The Dry Toilet is usually placed over a pit; if two pits are used, the pedestal or slab should be designed in such a way that it can be lifted and moved from one pit to another.
The slab or pedestal base should be well sized to the pit so that it is both safe for the user and prevents stormwater from infiltrating the pit (which may cause it to overflow)[[Image:dry_toilet.png|thumb|right|200px|Dry toilet, in Mexico]]

===Design Considerations===
The dry toilet is usually placed over a pit; if two pits are used, the pedestal or slab should be designed in such a way that it can be lifted and moved from one pit to another. The slab or pedestal base should be well sized to the pit so that it is both safe for the user and prevents stormwater from infiltrating the pit (which may cause it to overflow). The hole can be closed with a lid to prevent unwanted intrusion from insects or rodents. Pedestals and squatting slabs can be made locally with concrete (providing that sand and cement are available). Fibreglass, porcelain and stainless steel versions may also be available. Wooden or metal moulds can be used to produce several units quickly and efficiently.
==Adequacy==
Dry Toilets are easy for almost everyone to use. Because there is no need to separate urine and faeces, they are often the most physically comfortable and natural option.

==Health Aspects / Acceptance==
Squatting is a natural position for many people and so a well-kept squatting slab may be the most acceptable option.
Since ===Appropriateness===Dry Toilets do not toilets are easy for almost everyone to use though special consideration may need to be made for elderly or disabled users who may have a water sealdifficulty. When dry toilets are made locally, odours may they can be a problem depending on specially designed to meet the needs of the target users (e.g., smaller ones for children). Because there is no need to separate urine and faeces, they are often the Collection simplest and Storage/ Treatment technology to which it is connectedphysically most comfortable option.
==Maintenance=Health Aspects/Acceptance===The sitting or standing surface should Squatting is a natural position for many people and so a well-kept squatting slab may be kept clean the most acceptable option. Since dry toilets do not have a water seal, odours may be a problem depending on the Collection and dry to prevent pathogenStorage/disease transmission and Treatment technology connected to limit odoursthem.
===Operation & Maintenance=== The sitting or standing surface should be kept clean and dry to prevent pathogen/ disease transmission and to limit odours. There are no mechanical parts and so ; therefore, the Dry Toilet dry toilet should not need repairs except in the event that it cracks.
