Re: The Earth Auger Toilet: Innovation in Waterless Sanitation (Fundacion In Terris, Ecuador)
Yes, we are very happy with the foot flush, etc. and YES there is work to be done! We just now are working on final designs to send to the injection molding companies, and expect a complete new model by June-ish. We'll be sure to post at that time!

I really like that new "flushing" mechanism of the western-style version*. Seems perfectly suitable for in-home use. Obviously still a bit to do interface design wise, but for those good examples already exists (maybe it would be good to team up with an experienced UDDT toilet seat design company to avoid the common mistakes?).
However this seems to be an example of the small size of the company holding back the overall idea. I hope the exposure through these kind of events will interest someone with more financial reserves to speed up development and bring it to scale.

Hi!
Find attached the interview that SuSanA did to us during the Reinvent The Toilet Fair in India.
It was amazingly motivating being there. We get great connections from visitors, but also potential partnership and alliances with other exhibitors -plus the quick learnings and feedback that you can harvest just during the fair-. I will not say more, since I am sure that after playing the videos comments and questions will come!
Thanks SuSanA team for this!

Hi Elisabeth!
Prototype's final cost and other associated costs (as housing and restrooms accesories -urinals, sink, greywater pipes-) are still under research and development.
To supply the units or let the users doing it by theirselves is a good question. Critical Practices is now working on developing Injection-molded units because it is the most cost-effective way to manufactur the toilets, but the alternative of working in drawings and manuals for a "do it by yourself" is something that I know its under analysis.
The expectation would be that the unit's cost, Ex-Factory, would be between $100 and $200 depending on the prototype (Chuck can explain further about this). Then users can decide on superstructure and accesories, as well as installation. However, we are also developing easier and cost-effective approaches to the superstructure and accesories. One goal -thinkign in the Latin American context-, is that we could have a complete unit, including the Earth Auger toilet, accesories, superstructure, reainwater collection system and greaywater+urine irrigation system for less than $700; that could mean that users do a downpayment of aprox $80 and then monthly payments of $15 to $20 for 3 years. Of course a simpler alternative could be less than $500, including superstructure and basic accesories. We are approaching local MFI's in Ecuador and will have more information during the year.

Dear All,
I am in love with the innovation shown in this research.
I am currently working on waterless toilets piloting in a main market in Nigeria and will love to have all inputs to make it a success.
we have done the baseline and knew the preferences of the market users and had to develop a system where seperate facilities will be provided for male and female, in addition to some add-ons requested by the female respondents, during the qualitative data collection.
However, my main challenge is how do we limit odour to the barest minimum, reduce sight of faeces by toilet users, if possible and turn the end products, faeces and urine into organic fertiliser in a collaborative effort.
in addition, the 4-compartment units (4 each for male and female) is planned for privatization and i am concerned about success since the NGO that engaged our services is looking to market and replicate good practices.
I therefore request for support in this venture from group members.

Dear Marcos & dear Henry,
Why not teaming up with the South African Developer's of the first conveyer (auger) toilet (a non UD)? So many not written down and informal good and bad experiences made could be incorporated in your new R&D...
All the Best

Dear Marcos and Chuck,
Congratulations on this Phase 2 extension for your project! I looked up the grant amount in the publicly available database of the BMGF and found that it's nearly 1 million USD!:
www.gatesfoundation.org/How-We-Work/Quick-Links/Grants-Database
Not bad at all for a dry toilet research project! (who says the BMGF only funds high-tech things
).
I hope you will keep us posted about your progress in Ecuador.
I attach below a presentation that you had sent me by e-mail to make it available for others who are interested in your project. I have also uploaded it to the SuSanA library here:
susana.org/lang-en/library?view=ccbktypeitem&type=2&id=1779
About this objective:
How much will each toilet cost when you produce it at this large scale and will the families have to pay the whole amount, a fraction of the amount or nothing at all?
Are you envisioning a service provider model with a professional company or will the users handle everything themselves? (sorry if this has already been asked and I overlooked it)
Regards,
Elisabeth

About this objective:
1- To develop large-scale demonstrations of our new prototypes (a total of 300 to 500 toilets built and installed in Ecuador) in order to assess the acceptability, logistics, utilization of by-products (fertilizers) and fate (destruction) of pathogens.
How much will each toilet cost when you produce it at this large scale and will the families have to pay the whole amount, a fraction of the amount or nothing at all?

Re: The Earth Auger Toilet: Innovation in Waterless Sanitation (Fundacion In Terris, Ecuador)
Yes! My preference is to have it in the house, or attach something like this as an extension to a house with a door between. As we've seen in most of our installations, there simply is no room for a toilet; the addition of something like this that becomes part of the house is a real bonus, especially if it can include other ancillary features like a shower, sink, urinal, etc.

Re: The Earth Auger Toilet: Innovation in Waterless Sanitation (Fundacion In Terris, Ecuador)
We really liked the concept of the rotating sawdust delivery system that was, indeed as you pointed out, actuated as part of the single foot pedal operation. There are a few reasons that we are now testing this different system: (1) it can deliver any amount of cover material, rather than a fixed amount and at any time (i.e., you don't have to flush to add the cover material, conversely you don't have cover material added if you just want to move the material out of the chamber). (2) It is far more flexible for different cover materials used (is not as dependent upon the particle size). (3) yes, it is far less complex, thus much less expensive (something we are finding out is the biggest constraint we have heard from potential purchasers). Our goals continue to be first: effective, secondly: inexpensive, and finally: elegantly simple.

Yes! Similar, but different. We had some discussion about this. Check the posts before!

Dear Marcos,
Very Nice!
Looks to me a bit like the South African dehydration toilet:
at: www.ecosan.co.za/product_info.html
It seams to me you have a more lighter and simplified UD-version of a conveyer system too, right?
Good Luck
Detlef

Ahh, ok I understand. Those pictures look great by the way.
One small remark: So far it is missing some simple means for better access regarding elderly and people with disability.
I recommend you have a look at this:
wedc-knowledge.lboro.ac.uk/details.html?id=16357
P.S.: I think the real strength of this design is the possibility to include it in a house and not building such an "out-house". But I guess this is more for testing purposes, right?
