Re: Toilet design for a unique situation
Right, that's what I thought.
But then I don't understand what you meant with this statement:
Thank you, Chris. Interesting and useful reponse.
We are Muslims here in Pakistan. We use water in toilets. Thank you
To me it sounded like you are saying Muslims cannot use the type of toilet that Chris Canaday is talking about (urine-diverting dry toilet, UDDT)? If I got it wrong, what was the particular point you were trying to make, or was it just a general statement that had nothing to do with UDDTs?

Seems like you have got me wrong. Keep aside the name(s) of the toilets, for a moment.
Any toilet that allows anal cleaning with water is acceptable to Muslims.
You write: "But that doesn't mean they have to use flush toilets." Nearly 90 per cent of the households in the poor, rural areas here, do not have the facility of flush toilets, simply because, either they cannot afford it, or the arrangements for the flush toilets are not available. That doesn't mean that they don't use water for anal cleaning. Even in rural areas, no matter to what extent poor they are, the Muslim population always use water for anal cleaning.
Muslims do position their toilets, such that when are using the WC, they should not face Makkah.

Re: Toilet design for a unique situation
Can you please introduce yourself a bit more so that we know who is talking to us? Thanks a lot - and welcome to the forum!
Also, was your question referring to UDDTs or to one of the other toilets mentioned above?
If it was about UDDTs, then I want to point out that there is quite a bit of work with UDDTs in Bangladesh for the very reason that UDDTs can withstand floods better than pit latrines.
See e.g. here on the forum:
forum.susana.org/forum/categories/34-uri...nology-in-bangladesh
A famous photo of a UDDT in Bangladesh which is sitting pretty above the flood line:

Re: Toilet design for a unique situation
You keep pointing out that Muslims use water for washing after toilet use - I think most people are aware of this... I am assuming you are pointing this out here again because you are thinking that muslims can't use UDDTs (dry toilets) for this reason? If that is the case then you are mistaken.
We had a converation about it here on the forum:
forum.susana.org/forum/categories/34-uri...re-wipers-or-washers
Also, you find information about it here in the UDDT technology review:
susana.org/lang-en/library?view=ccbktypeitem&type=2&id=874
See on page 8:
3.3.3 Options for anal washing
The integration of anal cleansing with water is achieved through the installation of a separate wash bowl or washing area on the floor adjacent to the toilet seat (see Figure 7). The foremost design objective for UDDTs that accommodate anal washing is to minimise the risk of wash water entering the faeces vault. This is commonly achieved by installing a separate anal washing device. The washing mechanism must be equipped with a drain and discharge piping system.
Figure 7, right:

Figure 7. Left: Example in Kyrgyzstan with washing area in the centre of the photo (photo: WECF, 2011).

Another example from India (the anal washing area is towards the front of the photo):

And again from India (the anal washing area is towards the back of the photo, that second green pan):

Here again the photo that was mentioned above from Afghanistan (the anal washing area is towards the back of the photo):

Example from Morocco (the anal washing area is towards the right of the photo):

So in summary yes, Muslims use water in toilets. But that doesn't mean they have to use flush toilets. You need water to wash yourself and a place to do so. This can easily be provided, see above.
I am wondering: would you be happy to use such a toilet for example the one from Morocco? Or would there be anything holding you back? Anything specific to your faith maybe? (I know that the toilet mustn't be located so that the user's bottom would point towards Mecca)

A nice Urine-diverting Dry Toilet (UDDT) with an ample vent pipe, maybe 11 or 16 cm diameter, should be fine and odor-free inside the building, especially if a permanent staff member is interested and willing to check on it daily ... and education and consciousness-raising among the children should be constant, with an emphasis at the beginning of each school year. Older children could be required to clean up if they leave the toilet messy.
A single-chambered toilet with a plastic bin lined with woven sacks, which get changed as they fill, would be convenient, since there would be no fixed carrying capacity and the sack can be changed whenever there starts to be a problem with smell or flies.
A version for squatting could have a drop hole only 12 cm wide for the smallest children, so they do not feel like they will fall in. Similarly, a bench design could be made just the right height for each age group, as opposed to the flush toilet that comes in one single size generally ... and the urine diverter could also be accordingly smaller.
If there is electricity, there could be a fan connected to the light switch.
Cover material is also key ... and regular forum users know that I promote recycling the cover material, after a prudent detention time of drying and decomposing (and maybe spread in the sun to finish the treatment). This controls smell more than sawdust or ashes, plus it inoculates the new deposit with the microbes that broke down everything in the previous cycle. Sifting can get the rocks out, which can be boiled to also be recycled.

Re: Toilet design for a unique situation
Does anyone have a similar experience of people putting solid objects like rocks into the systems you've designed? Has anyone discovered a "foolproof" method of separating the these foreign objects from regular waste? I've considered grates, large P or S traps with removable U-Bends, and a trough with a reasonable run to carry waste but not rocks...
If anyone has tried or seen any of these methods tried, please let me know. The nature of this location is such that trial and error testing is almost impossible as I am only able to be on site 3-4 times a year. I'm strictly a volunteer and will likely be spending my own money on this design and implementation.
