Here is a look:



It was kept pretty clean and the overall construction was sound. It was missing an ventilation pipe though, but maybe the reason for that was that it gets very cold there and the UDDT was heated (a bit) and attached to the house (no direct airflow into the house though).

However the reason why I mentioned this installation was that this toilet was the single most complained about thing in the trip I took, and that was because of smell (or as one other tourist said "the most horrible toilet I ever used"). Of course being used to African communal pit-latrines it was actually not that bad, but I could definitely understand why people complained.

Given that "low odour" is a pretty big selling point of UDDTs, we as sanitation professionals should be very careful with this as the risk is high that seemingly false claims hurt a theoretically sound technology like UDDTs a lot.

That said, the issue was clearly overloading as there are easily a hundred tourists or more per day at that place, of which a significant part is probably using this two-stanced UDDT as it is the only toilet within 1-2 hours driving (and of course those that stay over night in the hostal... 30 people or so capacity).


(UDDT and hostal behind, not in that small house that serves as a changing room for the hot spring pool)

I also think that this issue is pretty common in other circumstances: Often toilets are shared amongst neighbours, and especially a newly constructed one will attract a lot of curious visitors.

It is therefore very important to note that UDDTs are a household level technology that due to the time it needs for feces to dry, can not be used by too many people in too short a time. This is a fundamental difference to pour-flush toilets and needs to be better communicated I think.]]>

Sorry for the delay....I am travelling in Asia...in process for returning to USA from Japan.

Here is the link to my dissertation abstract:

etd.lsu.edu/docs/available/etd-03312008-000156/

This is the link to my dissertation. In there are pictures in many places on the toilets, and the manufacturer of the toilet molds is in there with their catalog, and their contact information back in 2008. Just flipping through the report, you will easily find the pictures of the toilets and mold...recommend you look at all photos...they tell a story of the reality of implementation of "compost toilets" (urine diverting dehydration toilets - UDDT's)....and read what you wish, especially the abstract, introduction and conclusion. There are various tables and charts that are easy to read and quite revealing.

etd.lsu.edu/docs/available/etd-03312008-...ricted/Bates_dis.pdf

I will try to contact the manufacturer, confirm if their contact info reference above is still current, and see if they can ship you a mold and at what cost. They actually had a university make these molds out of fiberglass....not an easy process...and took years to refine the process... a process that we supported them with. The manufacturer/not for profit group has always been very reasonable in their costs and in supporting our organization and projects. The Architect's name who founded and runs their group is Cesar Anorve...look for him in my dissertation.

We need to discuss/confirm...exactly what you need.... a mold to make the basins, or how to make the mold itself...like I said a university made the sophisticated molds they use, but you can make the molds "by hand" in the field, which is how we started out.

More later,

The upside down bucket is simply a riser and the waste would fall right on through into the pit.

Thank you very much for your message, I am glad you enjoyed the video.

Regarding the questions you had:

- Yes, the toilet waste can be used as a fertilizer. Toilet users are trained on how to use the toilets properly as well as in harvesting and safe use of the 'humanure' produced. Our aim is to have more people using and/or selling this 'humanure' as fertilizer, which is very important especially in a highly agricultural country as Malawi.

- The ecological toilets use a urine diversion system. Only the solid waste goes to the chambers for composting, the urine is diverted with a soak away pit system.

- The 'action-research approach' is, as you say, a valuable method that we have been using for some time. You can find more information about the SHARE research project here www.shareresearch.org/

- In terms of the solid waste you see in the video. Waste management is a big problem in the country, where the government services for collection are minimum or inexistent. Most solid waste (around 70%) produced is organic, and the are building the capacity of community groups to set up enterprises to recycle this and produce compost manure, which they can then sell and generate income. In some areas, we support community groups are collecting waste (plastics in particular) and selling them to private recycling companies, whilst others are learning to produce recycled products from waste.

I hope this has helped to clarify some of your questions, and please be in touch if you require any further information.

Best wishes,

Mariana.-]]>

  1. Who took care of the toilet and who paid for him/her?
  2. How many hours per day did he/she spend on taking care of it?
  3. The container for the urine looks quite small, was it emptied daily?
  4. How is the container for the faeces accessed, do you have a photo for that? Is it by lifting up part of the toilet seat or is it by access from the back of the housing structure?
  5. Are you going to supply more constructions sites with such UDDTs or was this a one-off situation? Is there a potential market opportunity here?



1. We paid a women living near by during the construction time.
2. Max. 15 min
3. There are two urine container but yes - small. There is no use for the urine.
4. HAve a look in the manual (here) but yes you can take off the upper part. Very easy.
5. No market oportunity - in the case of interest we would provide it, but really no market in sight until now.

thanks for sharing insights of your work.

I am interested in the measures you take. As far as I understood, you construct more dry toilets and let people use soil and ash as cover material. Additionally, the new built toilets offer the possibility to use the excreta as fertiliser?

I am confused by the "UDDT"-title. I did not see any urine-diversion in the video.

Furthermore I am interested in the "action research approach". Sounds like a good method to me, collecting data with the community for further research and at the same time taking action to improve the sanitation situation.

I am wondering about the solid waste that gets thrown in the environment. Is there any concept how to handle this?

Best regards,

We have instructed some communities here in the Amazon to use wood ash, but the consensus later was that they had to be very careful to collect all of the ash or there was not enough for the UDDTs. And it is key for the cover material to never be lacking, which is all the more reason to use abundant materials and to recycle.

Ash could potentially be part of the mix, but my thinking is that we do not want to try to kill everything with pH, but rather allow the beneficial soil microbes, fighting on their home turf, to wipe out the pathogenic fecal microbes.

Limestone may be very abundant, but its transformation into powdered lime is very labor- or capital-intensive.

There must be some forest there somewhere. I would go out into the forest with a 1x1 cm mesh to separate out the leaves, sticks and roots. The same mesh can be used to sift the dried and decomposed barnyard manure. Even if you do not manage to get very much, a little bit of the right microbes goes a long way. (Please share these messages with the DNAE people; it would great to get their perspective.)

Rice hulls are great and should be very abundant there, so I would put 50% rice hulls.

Wood ash might best be mixed into the urine to improve its fertilizer value, as has been shown in several recent studies.

For the study, you might have 2-3 types of cover material, one being the mix I suggest, another being wood ash.

I suggest only filling the sacks to about 20 liters, so that they do not get too heavy. So changing the sacks can be part of a weekly routine, even if less feces have been collected.

(Thanks for pointing out that you were referring to my video. It seemed you were mentioning another.)

Sure, I'll take all the variables you can throw at this project ... as long as they come with your experience in how to work with them.**

I already omitted sawdust (not that plentiful), and will add D&D manure and soil. Really feel we must try firepit ash or powdered lime to raise pH; lots of 3 rock fires and limestone in Sumba. Your advice is noted.

Cheers,
Stew

** A couple years ago I participated in a joint Rotary Wasrag-UNC exercise to try and provide over 100 variables in various categories, in an effort to semi-automatically identify issues, weight them, and improve the quality of design in WaSH systems. The automation proved fruitless, though the categories did function as a checklist; and surveyors helped us a lot due to that preparation. There's no substitute for local knowledge of culture and conditions, experience in the field, and the wisdom to apply things judiciously. That's why I'm here, learning.]]>

Great discussion. Please do not worry about it going new directions.

About the cover material, I would suggest trying to include some kind of soil and/or dried and decomposed barnyard manure. Our climatic conditions here in the Amazon are comparable to those of Indonesia and when we used a mix of wood ashes and sawdust, we had a lot more problems with smell and flies than we do now with the use of recycled cover material. This could even be a new variable for your study (in case you are ready to handle more variables).
