Dear Cecilia,

I was at that conference, and I came back with a hardcopy of the proceedings which are now in the library at GIZ in Eschborn. This doesn't help you much...
Here is a scan of the first two pages so that you know at least what it looks like.
www2.gtz.de/Dokumente/oe44/ecosan/en-TOC...-conference-2008.pdf

(if you need a specific paper, perhaps someone at GIZ could scan it for you)

I also did a search on Google (which you have probably done, too), and found references to the proceedings but I think it exists either only as hardcopy or one has to pay for it (did you check in the IWA Publishing website?)

Either way, if you are looking for something on governance you might be disappointed. If I remmeber right, it was actually more technical than governance themes.

One of the presentations which I remember to this day from this conference was a presentation on Peepoo bags by Annika Nordin!
That one is the in the SuSanA library:
susana.org/lang-en/library/library?view=...p;type=2&id=1598

It is a pity that it still not yet standard to make all conference presentations available online after the conferences... (OK this one is 5 years ago now, but still).

So I suggest you search for the program and then contact the individual authors.
If you get some good presentations or papers, please ensure they also get put into the SuSanA library so that others can benefit.
Thanks!

Greetings from Rabat,
Elisabeth

P.S. Funny: when I searched on Google for the mentioned conference proceedings, guess which item came up first in the Google Search results? Your post! Ha! The Google algorithm likes this forum.

Hi Gerwin,

you need to invent your solution. With SuSana, you can find all the existing systems. If it does not exist, create it. But it is a long way and a lot of money; believe me.
I think that you can find a easier solution. Try to find a mix solution, using an existing system and you complete it by another part.
Sometimes, it is better than developing a complicated new system.
Good luck

Bernard,
Good to learn more about the workings of your fancy blue toilet! We thought of the first solution as well but rejected it because users would stay in the same squatting position when cleansing their ass, and thus foot activation will not work very well.
The new solution I like because the mechanism is more simple. However, there seems to be some clever hidden way of closing the lid when the hand shower is used. How does this work?
I'm very curious about the results of your tests in Kampala.
Cheerio

Emmanual, thanks!
I like the simplicity of your fluid/solid separation (and good job with the design of the toilet!). However, this solution does not meet my demand because it mixes water with urine. I'd like to keep the water separated from the urine (and feces) to avoid cross contamination. Any thoughts on that?

Hi Gerwin,

We are facing the same problem

We figured, there are basically two options;

1) separate the feces hole and the user during washing.
as you stated yourself, moving the user is no desirable option.
so you could move the feces hole away.
we did show this approach on the rttc fair in 2012.

lots of mechanics. probably not the best approach for our target market...

2) option two would be to cover the feces hole while washing.
much less mass has to be moved that way.
have a look at that approach:

still work in progress but I hope these ideas help...

best

Looking for the proceedings of the IWA Conference Sanitation Challenge: New Sanitation Concepts and Models of Governance - by: CeciliaRodrigues

Tue, 14 May 2013 16:37:18 +0000

Hello everyone,

I am looking for the proceedings of the International IWA Conference 'Sanitation Challenge: New Sanitation Concepts and Models of Governance', realized in Wageningen, May 19-21, 2008. I found only a couple of papers. Do any of you have the soft copy or know where to find it online? It may be available somewhere...

Thanks a lot in advance.

Best regards,
Cecília.

Hello,

I am manufacturing UD toilets using a conveyor belt and the conveyor separate urine and feces. Like that, you do not have different holes but only one. Have a look on my website. The english version is not update but you can find good information on it and you can also look at the drawing in the french version.
Tell me if you need more information

Regards

Hi Emmanel,
Please tell me more...

Hello,

I can provide you a solution with 1 hole and you can collect on one side feces and on the other side urine and wash water. Is it something interesting for you ?

Emmanuel

Dear all,

Since dry toilets are not suitable for 'washers', I was wondering if you know of any solutions that divert anal cleansing and flushing water from the waste. In other words, how can the waste (feces/urine) and water streams be collected separately? Squatting pans in specific. I'm aware of the pans with 3 holes, so I'm looking for other solutions (preferably the user does not have to move to another hole or bidet).

Much appreciated!
Gerwin

What is your perception of the health risk associated with sanitation systems and practices? - by: jonpar

Sat, 30 Mar 2013 21:52:14 +0000

Can you help me with my PhD research please? I need just 5 minutes of your time to respond to a short questionnaire...

Data on the reality of the sanitation situation in many cities in low income counties is often limited. Municipalities do not have the resources to do detail surveys of household and the local level sanitation systems.

As part of my PhD I am developing a rapid participatory risk assessment tool for urban sanitation systems. The tool asks communities to evaluate their situation and health risk against a number of indicators.

There is limited scientific data which quantifies the relative risk to human health posed by different poor sanitation systems and practices and therefore it is difficult to weight the different factors into an overall risk score.

I am interested to understand your perceptions of these risks. I would be grateful if you could fill in the questionnaire. It contains a bit of information about yourself and 3 questions relating to different elements of risk; sanitation systems, exacerbating factors and vulnerability.

Here is the link: www.surveymonkey.com/s/7J3WLCD

If you have internet issues - please get in touch and I can send a PDF copy that can be filled in off-line.

Many thanks,

Philippa Ross

Rough History of Sanitation in the West - by: mollydanielsson

Mon, 25 Mar 2013 17:33:52 +0000

Mathew Lippincott prepared this blog post, http://www.phlush.org/2012/11/27/a-rough-history-of-sanitation-in-the-west/, for PHLUSH.org before the Random Hacks of Kindness event in Seattle in December 2012, participating in Toilet Hackers. The event in Seattle was cancelled but the info is great and Trevor asked us to share it with you all. Below is an excerpt:

Researching sanitation is a passion of ours, so we, Molly and Mathew, thought we’d put together a very rapid rough history of sanitation in the US, Canada, and Western Europe in the past 200 years. There’s a stack of citations below, but the general thrust of this history can be credited to Joel A. Tarr’s essay Water and Wastes and the 1979 National Science Foundation report he chaired, Retrospective Assessment of Wastewater Technology in the United States, 1800-1972.

Oxygen is bubbled into to tanks of sewage to encourage soil bacteria to devour the nutrients in sewage. Keeping soil bacteria alive in water is energy intensive.
Piped water service began in the early 19th century before sewers were used for anything other than stormwater drainage. Convenient water that didn’t have to be hauled from a shared pump led to a 10-fold increase in water consumption that overwhelmed infiltration and open drainage systems. Worse, wealthier urbanites installed flush toilets. This new, unanticipated technology started overflowing the cess pits that otherwise contained undilute excrement that could accumulate for years without having to be emptied (facts and figures below). Sanitary sewers were built to mitigate overflowing sewage and eliminate the health risk related to the threat of disease from miasmatic sewer gas. These sewers failed to stop the spread of typhoid, increased its infection rates downstream of sewer outlets, and the miasmatic gasses they were designed to mitigate turned out to not exist.

Read more: check out http://www.phlush.org/2012/11/27/a-rough-history-of-sanitation-in-the-west/ with links to primary sources.

In related toilet news. Mathew just finished a Tedx Talk on March 23rd, in Portland about toilets and sanitation. It should be online soon.

Thank you,
