I suspect this system will emanate odor.
Worms do not like the ammonia (or something else) of urine, but if they can get away from it, it can work.
I imagine you'll want a more enclosed system with a leachate drain.
I would install active ventilation.
Let us know how it's working in one year.]]>

Social inclusion, toilet rights, and legal protection for transgender Americans (and unisex public toilets) - by: muench
Thanks for bringing this up! I've also been wondering about this: first we learn that gender separated public toilets are key (especially at schools), now we learn that unisex (or "all-gender") public toilets are also with merits. I would be keen to hear more from people outside of the U.S. how this conversation is perceived?

I have moved your post into an existing thread that Carol had started (please scrol up). I think it fits nicely together. Carol is THE expert on this topic for the situation in the U.S., where it has become a very hot topic, even going all the way up to the level of president Obama and now president Trump, as Carol explained in her posts.

Of course there are also Wikipedia articles about this topic which are rapidly developing:

There is this one on unisex public toilets:

And there is this one on Sex segregation in public restrooms:

I have suggested to my fellow Wikipedians to merge the two articles into one to avoid dublication of information (awaiting an outcome on that discussion).

Ti - Toilet Integration - Bus Toilet for women (Pune, Maharashtra, India) - by: muench
Thanks for posting about your work here on the Forum!
I recently created a specific sub-category for public toilets innovations in India, to make it easier to find these threads again. A few of them are about the eToilets by Eram Scientific.
This is the sub-category:

I have a few small questions to you just to get the ball rolling:
  1. Who is funding this pilot work? (You said: The pilot project has three Ti buses in Pune, Maharashtra stationed outside high footfall areas.)
  2. Is it easier/cheaper to install toilets and showers into old buses than it would be into standard shipping containers like others do? Or is it really important to be able to drive them to other places?
  3. What actually happens to the wastewater? Does it go to a sewer and treatment plant or is it treated onsite?
  4. How does your system compare to the eToilets of Eram Scientific?

I look forward to reading your answers.

Field testing of off-grid, self-sustained, modular, electronic toilet for slums, with water, energy/ fertilizer recovery (Eram Scientific, India) - by: svmidhu
eToilet is coming with auto flushing and floor washing mechanisms, remote monitoring capabilities, robust and strong structure which can easily installed at site, unique maintenance options and multiple revenue generations models. We are in search of a unique combined model of eToilet along with a perfect back end processing which can have the resource generation/recovery capability to cater increasing need of resources like water, electricity etc. all over the world.

This project will be conducted in 2 distinct phases. Phase 1 focuses on the design and construction of the community model eToilet and NEWgenerator. Phase 2 fully integrates the slum-based eToilet with the NEWgenerator, and demonstrates the successful operation of the combined system. Combining anaerobic membrane bioreactor (AnMBR) and solar (PV and thermal) technologies, the NEWgenerator allow for localized recovery of nutrients, energy and water from human wastes. This is accomplished by fully treating and recycling the flush water through the combined biological and membrane treatment system and by recovering energy in the form of biogas from anaerobic degradation.

This off-grid and modular treatment system enables the combined e-toilet/NEWgenerator system to be rapidly deployed to high-density urban areas as well as areas suffering from water scarcity and low-electrical grid connectivity.

This project is to provide a cost effective, modular sanitation technology that is relevant to broader segments of the Indian population. This will be accomplished by refining and adapting the existing electronic toilet, eToilet, design to ensure that it meets the specific needs of communities. Full integration of the eToilet and NEWgenerator will allow the combined system to be implemented in a greater variety of settings, including locations with unreliable or non-existent electricity and water connection.

Plans underway for five star public toilet (in Lae, Papua New Guinea) - by: shaji Public toilets, community toilets, shared toilets Tue, 14 Mar 2017 10:08:54 +0100 People counting system for public toilets? (Question from Malawi) - by: groverhmc
Currently WASTE Advisers is implementing the Sanitation Service Level Agreements in Blatyre Malawi, one of the components is Public Toilets. We are engaging private operators to run public facilities, we are analyzing different PPP modalities and one of the key parameters is to determine the number of users in public toilets. I am writing to get advice from any colleague who can recommend a people counting system for public toilets.
I will appreciate if you can share your experience and recommend any system.

Best regards

Updates on Sanergy in Kenya (public toilet business with urine diversion and composting) - by: kevintayler
I have just got onto this thread while looking for information on Sanergy's composting work. One of the presentations has a diagram showing the various units that are located on the treatment plant site. They include windrows, 'compost boxes' (which I take to mean the compost bins that are referred to in other publications and notes) biodigester and Biomax (in addition to the black soldier fly unit that Elisabeth has already explained is experimental.

I would be interested to know how the various units link - are they completely separate streams or do some of them link up (with windrows following compost boxes for instance. If they are separate streams, it would be interesting to know more about the purpose and, where appropriate, relative merits of the various streams.

Thanks in advance for replies

Festival toilets in Europe (Great Britain, France, Germany, ...) - by: Kevinkuhn
I want to give a quick update and answer the questions above.

First of all, there is a great article about the German market for sustainable festival toilets published at the 5th Dry Toilet Conference by Roach et al. :

That article might answer a couple of questions, however the sectors development is moving very quickly. The numbers are not correctly anymore and for example EcoToiletten has today around 300 composting toilets available and we fully covered the Feel Festival with 18.000 visitors on four days with 180 toilets. It is hard to tell what market share the companies altogether have, but it will be no more than 5%.

The companies (that I am aware of) are listed in the article. If one might also include the german speaking part of Switzerland, than there is also Kompotoi in Zurich. All of us are frequently in contact and meet at least once a year. No mergers happen so far and competition is fairly low. Everyone has the goal to promote sustainable sanitation in their own fashion.

We dispose the material usually to regular composting plants with the waste code "AVV 200399". But in a few regions only MBT plants are available. Also a few biogas plants take the material. However, waste water treatment plants are not an option for the solid residuals, because it would disorder the processes.

The supplier of chemical toilets dispose the material directly into municipal waste water plants. However the material need the be diluted with water by a factor of 20 (see attachted file from the Bavarian ministry for hydrology). Smaller treatment plants are unable to process that load in a short period. Therefore at larger events in rural areas the supplier of chemical toilets need to approach more WWTPs.

@Florent. Please keep us updated of the developments on the French market.

Struvite reactor For Festival in France - by: ben
1) As mentionned, the festival was organized by the communist party, so I call them the Comrads ... just a joke so.
2) We do have a couple of farmers accepting our urine in our homeland, in the south of France montpellier, but around Paris we don't have yet a re-use site. So unfortunatly all the urine was then thrown in the sewer.
3) We established a partnership with WC Loc, french leader of toilet renting (40% of the national market). They wanted for a long time shift to dry toilets systems but it was literaly impossible for their staff to deal with wood dust. So they welcomed very warmly our separation system with conveyor for several reasons :
  • The fact there's no emptying before 50 000 uses is ecnomicly very interesting for them
  • No electric or sewer connection is very interesting too
  • Only one person dealing with more than 15 cabins (cleaning / recharge of paper and gel) makes loads of savings
  • Obvioulsy communication on the ecological move

Paris has recently commited to place only ecological toilets in all the events next year, if the intention is proven in Public bidding soon there's good chances that WC Loc will renew it's park with a decent quantity of our systems. That would be a big shift for autonomous toilet market in france, stoping the sterile war between dry toiletes and plastic cabin renters that has lasted far too long.

The goal at ecosec is to democratized ecological sanitation, and we don't beleive this is possible if our solutions are not economicly competitive. We beleive with the reduction of manwork managing the cabins we can compete with other technologies.

Thanks for your interets
Best ,

Large centralized dry sanitation system in Tampere, Finland - by: muench
In case you missed it, a discussion about the "" which Carl mentioned above also took place on the forum here:

New strategy stops pollution and saves the plant nutrients for future recovery (new Smart Toilet from Sweden, a new type of composting toilet)

It might answer some of your questions, although maybe not the question about application for public toilets; the thread focused more about application at household level if I recall correctly.

Duncan Mara article on shared sanitation - by: JKMakowka

Doreen wrote: Shared sanitation facilities are paramount in low income urban areas and it is totally wrong to say that they are mostly unhygienic. The expectation that each family will have one toilet in a plot is just not feasible. Taking into consideration that many plots e.g. in Kenya have approximately 5 families living within the plot and there is very very limited space.

Sometimes I have the feeling that the people who actually contributed to some of these policy's/ SDG's have no background information on what is actually happening on the ground.

Yes you can get that feeling very often, but in this case I actually think it is just a different perspective of looking at the topic. SDGs etc. are mostly commitments by national governments and like the GDP are measured in really abstract terms like population coverage statistics and so on.

Based on previous experience, it is just way too easy for the respective government departments to hugely inflate coverage figures using shared sanitation. And even if parts of those shared sanitation facilities are perfectly fine, it is not a good thing to have a government proclaiming success in sanitation coverage (and then diverting funds to other sectors) when the reality on the ground is that unhygienic conditions, long waiting times and difficulties in night time access lead to many people using flying toilets as a common "backup".

Looking at it from this perspective also explains why there seems to be little movement to "soften up" the definition of shared sanitation and/or counting private neighborhood toilets differently, as these governmental negotiations are always a huge game of watering down everything (to avoid real commitments), and changing the definition of shared sanitation is seen as an attempt to water down minimum sanitation standards, even if technically justified.

Edit: over-crowed living conditions are also for many other reasons something the government should not be allowed to just accept by changing their minimum standards. Of course this is not something that will be possible to change over night, and in the meantime shared sanitation is often a good interim solution. But if it becomes accepted as a standard, the incentive to actually improve the overall conditions in the longer term (provide social housing etc.) becomes much lower for government technocrats that just care about numbers and minimum standards (and their next promotion ;) ).]]>

Méthode HIMO / Use of High Intensity Labor method to build public toilets and sanitation networks - by: cecile My specific question is what shall we do to ensure a good collaboration and coordination between
- beneficiaries who are not paid because they participate in the projet as part of their mandatory contribution
- regular workers who are employed to do so

I would think that the regular workers and the free workers should probably be given different tasks but I would like to have the feed back of practionners who have experienced this situation in the field.

Thanks for your help !]]>
