I really like your plan to build UDDTs without stairs. So many times I've seen UDDTs with steep and narrow stairs and wondered "is this really a good idea? How about the elderly and people with disabilities?!".
My gut feeling is that having the vaults below ground wouldn't be that detrimental to drying. Wouldn't most of the drying be influenced rather by the correct vent pipe arrangement and - more importantly - by users taking care of not letting urine enter the faeces vault? (provided you can ensure that no rainwater or flood water enters your vaults)

Also, I remember the UDDTs built in the Durban area used the slope of the ground to do away with stairs but still have the vaults mostly above ground. The user enters the toilet at the higher part of the slope and the access doors is at the lower part of the sloping ground. That's if the area is sloping a bit (see case study from 2011 here: and more documents in SuSanA library can be found by using the search term eThekwini).

Would be great if someone from EnviroSystems in South Africa could also comment. I will alert Jacques to this thread.

Please do let us know how you get on with those UDDTs in Ethiopia.

Therefore, I think they will be ok slightly buried.

Thanks for the advice - I would never have thought of that myself.

Re: FSM innovation challenge - iniated by The Netherlands Red Cross - by: JKMakowka It doesn't seem like there is any direct financial support to build the prototype or something like that?

I was actually working on this exact topic a few years back trying to do a PhD in sanitary engineering, but ultimately I had to shelve the idea because there was no-one willing to fund the production of a prototype. Yeah, maybe I am a bit bitter in that regard, but really: couldn't it be done like the Gates Foundation's innovation challenges that pre-select candidates and give a small start-up fund to get things rolling?

Anyways, I did a lot of research on this, and in my opinion the only technology capable of fulfilling the above requirements are ATADs. Maybe this company could be contacted and asked if they want to participate:

Back then they were mildly interested in the idea (really almost exactly what this project is asking for), but couldn't justify the expenses for building and testing a prototype.]]>

I work with a 4200l truck it only takes 7 to 15 minutes and it also depends with what type of effruent tht you are working on

Kind regards

FSM innovation challenge - iniated by The Netherlands Red Cross - by: fmeulman
Hi from a collaborative project between The Netherlands Red Cross and Open House - Amsterdam, The Netherlands. With this post I would like to create awareness of a new sanitation innovation challenge.

The Netherlands Red Cross is calling on companies to present innovative solutions for faecal sludge collection and treatment, to be used during humanitarian response. The Red Cross partners with Open House as the latter enables access to music festivals as a safe testing ground.

Please feel free to inform anyone that could contribute to this challenge. Below is a short description of the problem, some design requirements, and information to subscribe / get in contact.

The development of suitable treatment and disposal methods of large quantities of human excreta in (post) emergency settings has often been neglected due to other priorities. We aim to develop a system that can be rapidly deployed to safely collect and treat faecal sludge to prevent further harm to people affected by humanitarian disasters. The common problem regarding treatment and disposal facilities for emergency situations is the unavailability of cost-effective, rapid-deployable, low-tech and effective methods for the treatment and disposal of faecal sludge.

Solution design requirements
  • Small land footprint (<500m2)
  • Easily transported (flat pack, light and compact design; according to the following formula: 1m3 transport volume = 100m3 operational volume)
  • Can be installed on the surface rather than being dug-in the ground in case of floods / hard bedrock; Also usable in urban contexts
  • At least some of the material can be sourced locally
  • Installation is quick (no more than 2 weeks) and can be done with simple tools
  • Capable of dealing with liquid and semi-solid sludge (20m3 per day)
  • Minimum 2log pathogen reduction (99%) decontamination capacity
  • Waste does not need secondary treatment; can safely disposed of (e.g. dump-site)
  • Not dependent on existing infrastructure, can be deployed independently for 3mnths
  • If necessary supplied with own generator
  • Reasonable initial investment cost (<75k USD) and reasonable operational costs
  • Reasonable training requirements and labour requirements
  • The technology should be beyond initial design phase and have potential to scale-up
  • Supplied with scope for local business plan

Please submit proposals through
  • Click on ‘Register’ at the bottom of the page.
  • Then select ‘programs’ in the drop-down
  • Halfway the next page at ‘select a challenge’, select ‘humanitarian’ from the drop-down box.
  • All proposals should be in English.
  • Operational (prototype) testing should be possible during summer 2017.
  • Ideas / solutions not required to be fully developed or commercialized when submitted.
  • In the form, include technical, financial, user-acceptance and business model details.
  • Business model innovation is encouraged too: renting instead of owning? Or…?
  • You may add information on evaluation or operational test results.
  • The methodological and analytical rigour and independence of tests will be taken into account when assessing the track record.
  • Please provide a brief description of the track record of the company and (if applicable) details of previous projects and adaptations made to current models, evaluations and operational testing, and user-satisfaction surveys.
  • Do include a brief description of how the technology will be deployed or developed on site, and if prior preparation and/or local input is required of local populations.
  • A brief description of how the installed solution would be sustained – without additional external funding – and how the approach could be scaled up in the future also needs to be included.

Here you can find a file with all information:

Selected solutions will be introduced and operationally tested at selected festivals in 2017 in collaboration with and under the operations of Open House. After, The Red Cross can decide to apply successful pilots in aid camps. The Innovation Committee reserves the right to reject some or all applications.

Again, please feel free to inform companies or people you know that could contribute to this challenge. If you have any questions or require more information, feel free to contact Freek Meulman (Open House) at This e-mail address is being protected from spambots.

I have just registered for this virtual conference (my first one). I noticed that the program only becomes available AFTER registration (or is there a link for it? Maybe this link works even for non-registered people):

Also, could you please explain a little bit how this virtual conference will work. Which system will you use (Adobe Connect) and what is the time of the day?
Do I guess right that it starts at 8:00 New York time and finishes at 4:15 pm New York time?

My experience with webinars is that it helps people if you give them a few equivalent time zones, e.g. London, Delhi and Sydney. This makes it easier for people to orientate themselves.

Re: UUDT's in Zambia - for school in Ndola, in the Copperbelt region of Zambia - by: muench
Thanks for this additional information. Can you tell us more about this requirement by the Ministry of Education? Do they make recommendations about the type of toilet, maintenance and ownership issues? Do have a requirement for number of toilets per pupil? I recommend that you also install plenty of urinals (can be of the waterless type) as pupils might need to pee more than poo during a school day.

I am still working in the background to get some people with Zambia UDDT connections to reply to your post... With regards to reuse, that conference page from Tampere from 2015 (link in my previous post) had quite a bit of information (and we have more in the SuSanA library). Everyone agrees that urine is a very good fertiliser, it just needs to be applied correctly, but that's quite easy. The dried faeces is also a fertiliser but one needs to be more careful because of the pathogens that don't get totally destroyed by just drying in a UDDT.

For those who are new to this field (like yourself, I assume), we have listed here some key documents on urine reuse:

and here some key documents on excreta reuse in general:

And of course there's also a pretty good Wikipedia page on reuse of excreta:


P.S. Do you have any photos of the existing school toilets that you could post here?]]>

Discussion on incorporating the science of habit into behaviour change programmes - by: kurich
Here is a link to the recording, as well as a page that highlights resources that were mentioned during our discussion.

We wanted to expand the conversation to a broader group for the next couple of weeks. This is a two part question:
1. How can we practically incorporate the Science of Habit into behaviour change programmes on the ground, in a way that is usable to field users?
2. How can we strengthen an emphasis on habit formation into our existing behaviour change programmes?

Please feel free to address these questions above and/or post your own!

Re: How to measure job creation potential for sustainable sanitation systems? - by: stevensugden
The sustainability indicator below is taken from the Market Systems Development sector and one which I think has more meaning than most. It may be hard to measure consistently.

Indicator of sustainability = Adapt: The market player that adopted the behaviour/practice changes pioneered during the pilot has made qualitative and/ or quantitative investments that allow them to continue with or augment changed practices, without programme support. These actions, independent of the programme, constitute an ‘acid test’ for whether pro-poor outcomes will be sustained.]]>

Re: Request for advice on UDDT slab design - by: Angus
It has been suggested this might reduce the effectiveness of the drying inside the vault. Does anybody have any experience of vaults that are sunk below ground - did it make any difference to the drying?

Thanks again,
